Nuclear Energy Institute Comments on Quadrennial Energy Review 3

I. Introduction

The Nuclear Energy Institute1 (NEI) appreciates the opportunity to provide input to the

Department of Energy’s (DOE) Quadrennial Energy Review (QER). The Obama Administration

deserves great credit for recognizing the need for an integrated assessment of U.S. energy supply

and demand as a first step toward formulation of a coherent energy and environmental policy.

This QER – and a coherent energy and environmental policy for the United States – is long-

overdue.

NEI believes energy policy and environmental policy are inextricably intertwined. Any

meaningful discussion and analysis of one must include discussion and analysis of the other.

Accordingly, NEI’s comments will encompass both energy policy and environmental policy

issues.

NEI also believes that any assessment of America’s electricity policy must recognize that the

electric power industry operates with long time horizons. This industry invests in power plants

and other infrastructure that will operate for 40 to 80 years. It can take decades for the

consequences of policy decisions to play out. Once those consequences are recognized, it can

take decades more to implement course corrections.

The electric power business today is a product of decisions made 20 to 25 years ago – when the

1992 Energy Policy Act opened access to the transmission system and turned electricity

generation into a competitive business, when roughly one-half of the states decided to restructure

the electricity business and create competitive markets, when states began to establish renewable

portfolio standards.

Just as the electric power industry today is a product of decisions and investments made 20 to 25

years ago, so also the power sector 20 to 25 years hence will be the product of decisions and

investments made in the next decade or so. America’s electricity policy and planning, and this

year’s Quadrennial Energy Review, must reflect that reality.

By around 2050, electricity consumption will be 25-30 percent higher than today. Virtually all

of the generating capacity operating today will have been retired.

1 NEI is responsible for establishing unified nuclear industry policy on matters affecting the nuclear energy

industry, including regulatory, financial, technical and legislative issues. NEI members include all companies

licensed to operate commercial nuclear power plants in the United States, nuclear plant designers, major

architect/engineering firms, fuel cycle facilities, materials licensees, and other organizations and individuals

involved in the nuclear energy industry.

By mid-century, it is safe to say that the United States will:

have a meaningful program to eliminate air pollution from production of electricity,

including an economy-wide program to reduce emissions of carbon. This means that use

of natural gas – today’s fuel of choice – will be constrained and more costly, since a gas-

fired power plant produces roughly one-half the CO2 of a coal-fired power plant.

burn much less coal for electricity production (although coal will still be used extensively

around the world, as developing economies attempt to produce the electricity needed to

support economic growth and population growth).

place greater reliance on renewable sources of energy. This, in turn, places a high

premium on emission-free sources of electricity that are “dispatchable” and “flexible” –

i.e., that will operate when needed, and can fill in for those intermittent resources when

those resources are not available.

assign a high premium to technologies with a small environmental “footprint” – i.e.,

technologies that minimize land and water use, and minimize production of waste by-

products, typically by recycling them.

place a high value on technologies that can provide a broad range of services and

attributes – e.g., a product slate that might include electricity, process heat, hydrogen,

clean water for drinking and irrigation, and so forth.

be increasingly electrified, continuing a trend that has been underway for decades. The

share of the U.S. economy driven by electricity is growing, and will continue to grow –

as manufacturing substitutes electrotechnologies for direct burning of fossil fuels, for

example, and as electricity captures a larger share of the transportation sector.

Nuclear energy will play a strategic role in this future. NEI’s input to the 2016 Quadrennial

Energy Review discusses how and why nuclear energy must play a critical role in the transition

to an electric sector that is largely carbon-free, and outlines the policies necessary to ensure

nuclear energy’s promise is realized.

America’s Place in the World. The trends listed above are not confined to the United States.

Electrification and increasing reliance on carbon-free resources is a worldwide phenomenon –

necessarily so if the world is to achieve meaningful reductions in CO2 emissions.

The Energy Information Administration’s 2016 International Energy Outlook,2 forecasts a 69-

percent increase in world electricity generation by 2040, from 21.6 trillion kilowatt-hours (kWh)

2 http://www.eia.gov/forecasts/ieo/

Nuclear Energy Institute Comments on Quadrennial Energy Review 5

in 2012 to 25.8 trillion kWh in 2020 and 36.5 trillion kWh in 2040. “Electricity is the world’s

fastest-growing form of end-use energy consumption, as it has been for many decades,” EIA

notes.3 Electricity generation worldwide rises by 1.9-percent per year on average from 2012 to

2040, with the strongest growth in non-OECD countries. Increases in non-OECD electricity

generation average 2.5-percent per year – “as rising living standards increase demand for home

appliances and electronic devices as well as for commercial services, including hospitals,

schools, office buildings, and retail and grocery stores.” In the OECD nations, where

infrastructures are more mature and population growth is relatively slow or declining, electric

power generation increases by an average of 1.2-percent per year from 2012 to 2040.

In the world’s future, nuclear energy will play as important a role as it will in the United States.

The 2016 International Energy Outlook forecasts electricity generation from nuclear power

worldwide roughly doubling – from 2.3 trillion kWh in 2012 to 3.1 trillion kWh in 2020 and to

4.5 trillion kWh in 2040, “as concerns about energy security and greenhouse gas emissions

support the development of new nuclear generating capacity.”

If America wishes to retain its position as a world leader, it must lead this transition to a clean

energy future that includes a growing contribution from nuclear energy, not follow it.

3 This trend away from direct burning of fossil fuels and towards electricity is a common feature in all major

forecasts, including ExxonMobil (The Outlook for Energy: A View to 2040); the International Energy Agency’s

World Energy Outlook; the World Energy Council (World Energy Scenarios – Composing Energy Futures to 2050),

and the “New Lens Scenarios” from Royal Dutch Shell.

II. Executive Summary

The Obama Administration has embraced two signature initiatives in energy and environmental

policy – an “all of the above” energy policy and a commitment to reduce carbon emissions from

the electric power sector, as evidenced by the Environmental Protection Agency’s regulations to

reduce carbon emissions from new and existing sources.

Neither of these initiatives can succeed without preserving and expanding America’s existing

nuclear energy infrastructure.

Stated another way, both of these initiatives are at serious risk, to the extent the United States

continues to shut down operating nuclear power plants, and fails to make provision for the new

nuclear generating capacity that will be needed starting in the next decade.

NEI believes that our nation’s nuclear energy assets – the 100 nuclear power plants that provide

approximately 20 percent of the nation’s electricity and approximately two-thirds of the nation’s

carbon-free electricity – provide a uniquely valuable set of attributes:

Nuclear power plants produce large quantities of electricity around the clock, safely and

reliably, when needed. They operate whether or not the wind is blowing and the sun is

shining, whether or not fuel arrives by truck, barge, rail or pipeline when needed.

Nuclear plants provide price stability.

They provide “reactive power” – essential to controlling voltage and frequency and

operating the grid.

Nuclear power plants have portfolio value, contributing to the fuel and technology

diversity that is one of the bedrock characteristics of a reliable, resilient electric sector.

Finally, nuclear power plants provide clean air compliance value. In any system that

limits emissions – of the so-called “criteria” pollutants or carbon dioxide – the emissions

avoided by nuclear energy reduce the compliance burden that would otherwise fall on

emitting generating capacity.

Other sources of electricity have some of these attributes. None of the other sources has them

all.

According to a recent analysis by The Brattle Group,4 nuclear energy:

contributes approximately $60 billion annually to gross domestic product;

4 The Nuclear Industry’s Contribution to the U.S. Economy, The Brattle Group, July 2015.

accounts for about 475,000 full time jobs (direct and secondary);

helps keep electricity prices low. Without nuclear generation, retail rates would be about

6 percent higher on average, and

is responsible for nearly $10 billion annually in additional federal tax revenues, and $2.2

billion in additional state tax revenues.

These values reflect the incremental contribution of the nuclear industry to the economy,

measured by comparing the performance of the U.S. economy with and without the nuclear fleet.

This approach nets off the

contribution of the

alternative generation that

would be necessary if the

nuclear industry did not

exist, to determine its

incremental contribution.

Without nuclear plants, the

economy would rely more

heavily on existing and new

natural gas-fired generating

plants, and to a lesser

extent, additional

generation from existing

coal-fired plants. This

greater use of fossil

generation would mean

higher electricity prices – wholesale prices would be 10 percent higher on average; retail prices

would rise about 6 percent.

Nuclear energy is America’s largest source of low-carbon electricity. In 2015, nuclear energy

produced 19 percent of U.S. electricity supply (797 billion kilowatt-hours) and prevented 564

million metric tons of CO2 emissions.

Nuclear energy accounted for 62 percent of America’s carbon-free electricity in 2015 – three

times more carbon-free electricity than hydropower and four times more than wind energy. For

perspective, just three typical nuclear power stations produce approximately 24 billion kilowatt-

hours of carbon-free electricity every year – approximately equal to the production from all

utility-scale solar in the entire country in 2015.5 The amount of CO2 emissions avoided by U.S.

nuclear energy facilities is equal to the CO2 emissions from 128 million passenger cars – more

5 U.S. utility-scale solar output in 2015 was 26 billion kilowatt-hours.

Nuclear Energy Institute Comments on Quadrennial Energy Review 8

than all the passenger cars in

the United States. Without

nuclear power plants

operating in 30 states,

carbon emissions from the

U.S. electric sector would be

27 percent higher.

In those states fortunate

enough to enjoy the zero-

emission, safe, reliable, low-

cost electricity from nuclear

power plants, nuclear energy

represents the major portion

of those states’ carbon-free

electricity. In Alabama, for

example, nuclear energy

represents 81 percent of the

state’s carbon-free

electricity; in Arkansas, 79 percent; in Connecticut, 97 percent; in Florida, 98 percent; in Illinois,

91 percent; in Minnesota, 54 percent; in Mississippi, 100 percent; in New Jersey, 98 percent; in

New York, 60 percent; in

Ohio, 91 percent; and in

Pennsylvania, 94 percent.

All mainstream analyses of

the climate change issue by

independent organizations,

in the United States and

around the world, show that

reducing carbon emissions

will require a portfolio of

technologies, that nuclear

energy must be part of the

portfolio, and that major

expansion of nuclear

generating capacity over the

next 15-30 years is

essential.6 According to the

most recent assessment by the United Nations’ Intergovernmental Panel on Climate Change: “No

single mitigation option in the energy supply sector will be sufficient. Achieving deep cuts [in

emissions] will require more intensive use of low-GHG technologies such as renewable energy,

nuclear energy and CCS [carbon capture and storage].”

America’s 100 nuclear reactors are also a significant Clean Air Act compliance tool. They avoid

over one million tons of sulfur dioxide and 650,000 tons of nitrogen oxide emissions annually.

In the absence of nuclear energy, emissions of SO2 and NOx from the U.S. electric sector would

be 13 percent and 18 percent higher every year, respectively.

In its analysis,7 The Brattle Group estimated the value to society of the emissions avoided by

America’s nuclear power plants, using the federal government’s social cost of carbon emissions

($43.31 per ton) and the National Academy of Sciences’ externality estimates for SO2, NOx,

PM-10 and PM-2.5. The analysis showed that the avoided social cost of carbon emissions

avoided by nuclear

energy is almost $25

billion per year. The

avoided costs of SO2

and NOx are $7.2

billion and $1.2 billion,

respectively. The

avoided costs of

particulate matter

emissions are

approximately $0.7

billion.

Nuclear energy

facilities (like other

carbon-free sources of

electricity) do not

produce greenhouse

gases when they

generate electricity, but the processes used to build and fuel the plants do. This is true for all

energy facilities. Independent studies have assessed nuclear energy’s life-cycle emissions and

found them to be comparable to wind, solar, geothermal and hydroelectric generation.

Even at less-than-one-percent annual growth in electricity demand, the Energy Information

Administration (EIA) forecasts a need for 196 gigawatts of new electric capacity by 2040 (22-

7 The Nuclear Industry’s Contribution to the U.S. Economy, The Brattle Group, July 2015, p. 13.

Page 10: Department of Energy’s...Jul 01, 2016  · Department of Energy’s (DOE) Quadrennial Energy Review (QER). The Obama Administration deserves great credit for recognizing the need

percent growth) in the United States. To satisfy this demand at lowest possible cost without

compromising the nation’s environmental goals, the U.S. electric power industry must have a

portfolio of electricity generating technologies, particularly low-carbon technologies.

Unfortunately, trends are moving in the other direction. America’s electric generating

technology options are narrowing dramatically:

Coal-fired generating capacity is declining in the face of increasing environmental

restrictions, including the likelihood of controls on carbon, and uncertainty over the

commercial feasibility of carbon capture and sequestration. The U.S. has about 280,000

MW of coal-fired capacity, and the consensus is that about 60,000 MW of that will shut

down by 2021 because of escalating environmental requirements.8 In addition, the

pipeline of coal-fired projects under development is all but empty.

Natural gas-fired generating capacity is growing dramatically. Since 1995, the United

States has built approximately 367,000 megawatts of gas-fired capacity, approximately

73 percent of all capacity additions. Coal and nuclear, the two sources of electricity that

can produce electricity around-the-clock at stable prices, represent a scant six percent of

the generating capacity added. Clearly, the United States should not continue to build

only gas-fired generating capacity.

Renewables will play an increasingly large role but, as intermittent sources, cannot

displace the need for baseload generating capacity, absent dramatic advances in energy

storage.

According to analysis by IHS Energy,9 the United States “is at a critical juncture because in the

next decade the need for power supply to meet increased customer demands, replace retiring

power plants, and satisfy policy targets will require fuel and technology decisions for at least 150

gigawatts (GW) – about 15 percent of the installed generating capacity in the United States ….

[C]urrent trends in energy policy could push that power plant turnover percentage to as much as

one-third of installed capacity by 2030. The implication is clear: Power supply decisions made

in the next 10-15 years will significantly shape the U.S. generation mix for decades to come.”

NEI believes that the Quadrennial Energy Review must begin by acknowledging the challenges

facing the U.S. electric power sector:

8 This is the estimated coal-fired capacity likely to be shut down due to existing regulation of so-called “criteria

pollutants” (e.g., SO2, NOx, fine particulates, mercury, air toxics). The Environmental Protection Agency’s

regulation to reduce carbon emissions from existing power plants would lead to an additional 30,000-35,00 MW of

coal-fired retirements, by most estimates. 9 The Value of U.S. Power Supply Diversity, IHS Energy, July 2014.

Page 11: Department of Energy’s...Jul 01, 2016  · Department of Energy’s (DOE) Quadrennial Energy Review (QER). The Obama Administration deserves great credit for recognizing the need

Nuclear Energy Institute Comments on Quadrennial Energy Review 11

The U.S. electricity sector is losing one of its major strengths – fuel and technology

diversity. A diverse portfolio of generating options is an essential characteristic of a

robust and resilient system. If current trends continue, that diversity is seriously at risk.

The United States is at risk of becoming overly dependent on one fuel for production of

electricity – natural gas. This could expose consumers of natural gas and electricity to

price volatility and loss of reliability. Some parts of the country have already had

repeated warnings.

The merchant markets serving large portions of the United States are still – almost 15

years since restructuring and deregulation – not functioning as they should. The

competitive markets are not providing the price signals necessary to stimulate investment

in new generating capacity (except for gas-fired capacity), or providing the prices

necessary to support continued operation of existing capacity – including, in some cases,

nuclear generating capacity.

Significant changes in the electricity landscape are coming in the next few decades as

much of today’s generating capacity reaches retirement age. For example, between 2029

and 2055, all 100 operating reactors will reach 60 years of life. Replacing these facilities

with new ones, which will operate for 40-60 years at least, will be a capital-intensive,

multi-decade proposition.

With a clear understanding of the challenges, the policy discussion can then turn to identifying

the solutions.

Recommendations

It is clear that preserving existing nuclear generating capacity, and preparing to build relatively

large amounts of new nuclear capacity starting in the next decade, are strategic imperatives.

Failing to do so would seriously compromise U.S. energy and environmental goals. A

continuing, growing contribution from nuclear energy is essential to produce the baseload

electricity needed at stable prices, and to sustain reductions in emissions of carbon and other

pollutants.

Given that, NEI proposes a number of actions to maintain the operating nuclear power plants and

to create the conditions under which companies can build new nuclear power plants when

needed. Some require federal legislation; some can be accomplished by Executive Branch

action; some require state government action, or action by the Regional Transmission

Organizations.

Page 12: Department of Energy’s...Jul 01, 2016  · Department of Energy’s (DOE) Quadrennial Energy Review (QER). The Obama Administration deserves great credit for recognizing the need

Nuclear Energy Institute Comments on Quadrennial Energy Review 12

NEI has identified several priority areas:

1. Preserving existing nuclear generating capacity;

2. Continuing construction of large Generation III+ light water reactors, to capitalize on the

lessons learned during construction of the Vogtle and Summer plants in Georgia and

South Carolina;

3. Developing a credible roadmap for small modular reactor deployment (which represent a

large growth opportunity in the United States and worldwide10

), and

4. Developing a durable program to finance development, demonstration and deployment of

advanced nuclear technologies.

10

Small modular reactors are particularly well-suited as a zero-carbon baseload option for developing nations that

may not have well-developed transmission and distribution systems. Whatever the nuclear technology, however,

U.S. engagement in the world’s nuclear markets is essential, and not just for commercial and economic reasons.

Absent such engagement and leadership, the United States will not be in a position to influence safety practices,

regulatory frameworks or nonproliferation policy around the world. America must begin to treat commercial

nuclear energy exports as an instrument of U.S. foreign policy, as a means of projecting U.S, influence around the

world, in much the same way as the U.S. government treats military sales. Other nations, including Russia, do this

routinely.

Nuclear Energy Institute Comments on Quadrennial Energy Review 13

III. Fuel and Technology Diversity: Portfolio Value at Risk

All fuels, all technologies carry some level of risk. In extreme cold, coal piles at coal-fired

stations freeze, shutting down the power plants. Frozen rivers can halt barge deliveries of fuel.

Natural gas wells shut down in the winter when moisture in the gas freezes at the wellhead.

Wind farms tend to produce least when electricity demand is highest, and vice versa. Nuclear

power plants sometimes shut down as a precaution in advance of major hurricanes.

Some technologies – coal and nuclear power, for example – have high initial capital costs and

long permitting and construction times, but low, stable and predictable operating costs. Others –

gas-fired power plants, for example – have low capital costs and can be built relatively quickly.

But approximately 90 percent of the cost of electricity from a gas-fired combined cycle plant is

the cost of fuel, so these plants are very sensitive to fluctuations in fuel price. And although

there are no doubts about the size of the natural gas resource base, there are concerns about

whether the necessary infrastructure – gathering systems, gas processing facilities and pipelines

– will be in place at the right time.

Page 14: Department of Energy’s...Jul 01, 2016  · Department of Energy’s (DOE) Quadrennial Energy Review (QER). The Obama Administration deserves great credit for recognizing the need

Nuclear Energy Institute Comments on Quadrennial Energy Review 14

A diverse portfolio of fuels and technologies – coal, nuclear, natural gas, hydro, non-hydro

renewables, efficiency – is the core strength of the U.S. electric power supply system. This fuel

and technology diversity serves as a hedge against price volatility or supply disruptions in any

part of the portfolio. As with a financial portfolio, risks are lower with a diversified mix of

assets.

In the electric power sector, this fuel and technology diversity is at risk. Since 1995, the United

States has built approximately 367,000 megawatts of gas-fired capacity, approximately 75

percent of all capacity additions. Coal and nuclear, the two sources of electricity that can

produce electricity around-the-clock with virtually no price volatility, represent a scant six

percent of the generating capacity added.

In addition, a significant amount of U.S. fossil-fueled generating capacity is expected to shut

down in the next 5 years or so, largely due to increasingly stringent environmental requirements.

Consensus estimates suggest that approximately 170 gigawatts (GW) of generating capacity –

over 10 percent of U.S. generating capacity – will be retired this decade. Nearly 75 gigawatts

(GW) of U.S. generating capacity has shut down since 2011, and an additional 93 GW is

expected to be retired by 2020.

Much of this capacity (60,000 megawatts or more) is coal-fired capacity – typically older,

smaller coal-fired plants, which will close because it does not make economic sense to invest in

the pollution control technology necessary to meet tighter environmental requirements

(particularly the limits on mercury and air toxics). Some of the capacity that will be shut down is

old oil-fired and gas-fired steam capacity. Unlike the modern, efficient gas turbine power plants,

this steam capacity is inefficient and costly to operate.

The Environmental Protection Agency’s (EPA) rule to reduce carbon emissions from existing

power plants will only add to these numbers. Most analyses show that EPA’s rule could force

shutdown of an additional 30,000-35,000 MW of coal-fired generating capacity.

In addition, five nuclear power plants have shut down prematurely in the last three years, an

additional nine reactors are scheduled for premature retirement over the next several years, and

(as discussed in Section V) others are at risk.

Until very recently, Americans enjoyed the benefits of a diverse portfolio of electricity sources,

based on fuel and technology decisions made decades ago. This diversity is taken for granted,

difficult to quantify and, as a result, undervalued. In a 2014 analysis,11

IHS Energy

demonstrated analytically the value of fuel and technology diversity. IHS compared a base case

11

The Value of U.S. Power Supply Diversity, IHS Energy, July 2014.

Page 15: Department of Energy’s...Jul 01, 2016  · Department of Energy’s (DOE) Quadrennial Energy Review (QER). The Obama Administration deserves great credit for recognizing the need

Nuclear Energy Institute Comments on Quadrennial Energy Review 15

– reflecting the current generation mix in regional U.S. power systems during the 2010-2012

period – with a reduced diversity case involving a generating mix without meaningful

contributions from coal and nuclear power, with a smaller contribution from hydroelectric power

and an increased share of renewable power. The remaining three-quarters of generation in the

scenario would come from natural gas-fired plants. This is clearly the direction in which the

United States is heading.

In this analysis, IHS found that:

the cost of generating electricity in the reduced diversity case was more than $93 billion

higher per year, the potential variability of monthly power bills was 50 percent higher

compared to the base case, and retail electricity prices 25 percent higher.

The typical household’s annual disposable income was around $2,100 less in the reduced

diversity scenario.

There would be around one million fewer jobs compared to the base case and U.S. gross

domestic product (GDP) would be nearly $200 billion less.

“These negative economic impacts are similar to an economic downturn,” IHS said. “Additional

potential negative impacts arise from reducing power supply diversity by accelerating the

retirement of existing power plants before it is economic to do so. For example, a transition to

the reduced diversity case within one decade would divert around $730 billion of capital from

more productive applications in the economy.”

IHS Energy concluded:

“The economic benefits of diverse power supply illustrate that the conventional wisdom

of not putting all your eggs in one basket applies to power production in much the same

way as it does to investing. This is the portfolio effect. In addition, diversity enables the

flexibility to respond to dynamic fuel prices by substituting lower-cost resources for more

expensive resources in the short run by adjusting the utilization of different types of

generating capacity. This ability to move eggs from one basket to another to generate

fuel cost savings is the substitution effect. Looking ahead, the portfolio and substitution

effects remain critically important to managing fuel price risks because of the relative

fuel price dynamics between coal and natural gas.

“The shale gas revolution and restrictions on coal are driving an increased reliance on

natural gas for power generation and provide strong economic benefits. However, this

past winter demonstrated the danger of relying too heavily on any one fuel and that all

fuels are subject to seasonal price fluctuations, price spikes, and deliverability and

infrastructure constraints. The natural gas price spikes and deliverability challenges

Nuclear Energy Institute Comments on Quadrennial Energy Review 16

during the past winter were a jolt for a number of power systems that rely significantly on

natural gas in the generation supply. These recent events demonstrated that natural gas

deliverability remains a risk and natural gas prices continue to be hard to predict, prone

to multiyear cycles, strongly seasonal, and capable of significant spikes. The root causes

of these price dynamics are not going away anytime soon. The best available tool for

managing uncertainty associated with any single fuel or technology is to maintain a

diverse power supply portfolio.”

IV. Natural Gas Dependence: Warning Signs

Natural gas has many advantages – a relatively clean burning fuel, sourced domestically, with a

large resource base. Low-cost natural gas is driving a manufacturing renaissance in the United

States – particularly in the chemicals industry in the Gulf Coast states. Power plants fueled with

natural gas have many unique advantages. Simple cycle gas turbines and combined cycle plants

are flexible and relatively nimble – increasingly important for regions with large amounts of

intermittent renewable generating capacity.

Gas-fired capacity has long been used to meet peak demand and mid-merit or intermediate load

requirements. For the last decade, the capacity factor of the combined cycle fleet has averaged in

the low- to mid-40-percent range. Current trends suggest, however, that these plants are

increasingly used to meet baseload requirements, running 24-by-7.

Excessive reliance on natural gas carries with it vulnerability to price volatility and supply

interruptions. The United States has had repeated warnings over the last five years of the

dangers associated with excessive dependence on natural gas. In 2011, it was Texas; in the

winter of 2013, New England; in the winter of 2014,the PJM region and the midcontinent.12

This year, the warning came in southern California, the result of major problems with the Aliso

Canyon natural gas storage reservoir.

In October 2015, a gas leak was detected at the Aliso Canyon natural gas storage facility in

southern California. The Aliso Canyon facility is a critical component of the gas system in the

Los Angeles Basin. It is one of the largest natural gas storage facilities in the U.S. and is

essential in providing a reliable gas supply to 18 large power plants with approximately 9,800

megawatts of capacity in the Los Angeles basin. Of its 86 billion cubic feet (Bcf) working gas

capacity, only 15 Bcf is being stored currently. 13

There is a moratorium on injection of fuel into

Aliso Canyon until all wells at the facility have been checked and appropriate action taken to

ensure no further leaks. On as many as 12 to 21 days, gas service curtailments could be large

enough to force the California ISO and LADWP [Los Angeles Department of Water and Power]

to curtail electricity service to customers across a wide area in the L.A. Basin. Fourteen of these

days could occur in the summer.

In a recent report – another in a series of such reports going back several years – the North

American Electric Reliability Council warned of the threat to reliability associated with

excessive dependence on natural gas in the power sector:

“Until recently, natural gas interdependency challenges were most experienced during

extreme winter conditions and focused almost exclusively on gas delivery through

pipelines. However, a recent outage of an operationally-critical natural gas storage

facility in Southern California—Aliso Canyon—demonstrates the potential risks to BPS

reliability of increased reliance on natural gas without increased coordination between

the two industries. The risk associated with Aliso Canyon, which may result in controlled

load shedding, is expected to persist through the 2016 summer season, and potentially

into the 2016/2017 winter and 2017 summer seasons. The challenges faced in

California represent a series of risks that have been layered into the system over the

past decade: significant dependency on a single and just-in-time delivery fuel source,

specifically for ramping capability to meet load and generation variability; reduced

amount of baseload and dispatchable resources; increased amounts of variable and

distributed resources; increasing need of system flexibility; gas system dependency on

storage to maintain operating pressure; and a lack of clear understanding of natural gas

operational characteristics and potential impacts on BPS [bulk power system] operations

….(Emphasis added.)

“[A]reas with a growing reliance on natural gas-fired generation are increasingly

vulnerable to issues related to gas supply unavailability. Common-mode, single

contingency-type disruptions to fuel supply and deliverability in areas with a high

penetration of natural gas-fired generation are reducing resource adequacy and

potentially introducing localized risks to reliability …. Not only can impacts to BPS

reliability occur during the gas-load peaking winter season, but they can also manifest

during the summer season when electric demand is high and natural gas facilities are out

of service, which can lower the operational capacity and flow of the pipeline system ….

“As gas-fired generation increases, the amount of generation capacity potentially

impacted also increases, particularly when conditions affect a wide geographic area and

support from the neighboring areas is unavailable. [E]xtreme weather events serve as

early indicators of more frequent impacts to the BPS as more natural-gas-fired units

continue to rely solely on just-in-time and non-firm fuel sources.”

Particularly in New England, the grid operator continues to raise concerns about the region’s

growing dependence on natural gas for power generation. In its 2016 Regional Electricity

Outlook, published in January 2016, ISO New England notes:

“[W]intertime access to natural gas has grown tight over recent years because the

regional fuel transportation network has not kept up with demand from both generation

and heating sectors. These natural gas constraints have led to grid reliability challenges,

emission increases during winter, and spikes in wholesale electricity prices. The

situation is exacerbated by other market dynamics: low gas prices during most of the

Page 19: Department of Energy’s...Jul 01, 2016  · Department of Energy’s (DOE) Quadrennial Energy Review (QER). The Obama Administration deserves great credit for recognizing the need

Nuclear Energy Institute Comments on Quadrennial Energy Review 19

year except winter are putting economic pressure on coal, oil, and nuclear resources. By

2020, resources representing about 30% of regional capacity have committed to cease

operation or are at risk of retirement. Taking their place are even more natural-gas-

fired units—currently, more than 60% of new generation being proposed by private

investors across the six states will be primarily or exclusively fueled by natural gas ….

The region’s growing dependence on natural gas for power generation exposes consumers of

electricity to increasing price volatility:

“Because so much of the region’s generating capacity runs on natural gas, the price of

this single fuel source sets the price for wholesale electricity about 70% of the time. Both

electricity and gas prices have seen dramatic swings in recent years. Between February

and June 2015, for example, the region’s average monthly wholesale electricity price

plummeted from the third-highest price to the lowest price since 2003, the year that

competitive markets in their current form were introduced in New England. Behind these

ups and down is the region’s inadequate natural gas delivery infrastructure, which can

cause price spikes.” (Emphasis added.)

When New England’s gas-fired generators have unconstrained access to natural gas, wholesale

electricity prices are competitive nationally. During the winter, when gas supplies are

constrained, it is a different story.

In its report, ISO-New England compares electricity and natural gas prices in the Midcontinent

ISO with those in New England during an average summer (June–August 2015) and winter

Gas-Fired Power Plants: A Strain on the System

Natural gas-fired power plants running at baseload consume prodigious volumes of natural gas.

Among all customer classes, a single gas-fired power plant is generally the largest single

consumer of natural gas on the system. A 1,000-MW gas plant burns more gas in a day than

peak sendout for many large gas distribution companies. A one-thousand-megawatt gas plant

running at 90 percent capacity factor burns 59-60 billion cubic feet a year – the same quantity as

New Hampshire’s entire natural gas consumption in 2015, and more gas than 18 states burned

for electric power production in 2015.

Power plant loads are a challenge for gas pipelines. “Even on non-peak days, gas-fired

generation requires

high-volume, high-

pressure loads with

large load swings that

pipelines may not

have been designed to

accommodate,” says a

2013 report from the

North American

Electric Reliability

Corp.14

“Pipelines

need to align a slow-

moving product (gas)

with a fast-moving

product (electricity)

that is subject to large

variations (gas-fired

generators come on-

or off-line on short

notice). The sudden demand swings from generators may cause pipeline pressure drops that

could reduce the quality of service to all pipeline customers.”

Several analyses have shown that a large gas-fired combined cycle power plant could easily draw

down a gas pipeline’s “line pack” in a matter of hours, potentially compromising the pipeline’s

ability to serve other customers. (Line pack is the amount of gas held in the pipeline at any given

time. It represents a localized form of short-term gas storage that pipeline operators can use to

meet fluctuating demand from firm customers. In the winter, when gas demand typically peaks,

pipelines build up line pack overnight, then draw it down during the day to meet demand.)

Conclusion

At a time when the conventional wisdom holds that the United States has virtually limitless

supplies of natural gas at low prices, it is not fashionable to question whether or not those

resources will be available when needed, where needed, at stable prices – the criteria by which

electric sector fuel sources should be judged.

It’s clear, however, that growing U.S. electric sector dependence on natural gas deserves

attention. In its report reviewing the performance of America’s bulk power system during the

2014 Polar Vortex, the North American Electric Reliability Corp. observed:

“Unlike coal and fuel oil, natural gas is not easily stored on site. As a result, real‐time

delivery of natural gas through a network of pipelines and bulk gas storage is critical to

support electric generators. Natural gas is widely used outside the power sector, and the

demand from other sectors—particularly coincident end-user gas peak demand during

cold winter weather—critically affects the gas providers’ ability to deliver interruptible

transportation service in the power sector. Additionally, demand for natural gas is

expected to grow in other sectors (e.g., transportation, exports, and manufacturing).

“As observed during the polar vortex, increased reliance on natural gas exposed the

industry to various challenges with fuel supply and delivery. These challenges are

predicted to escalate as more baseload generating plants are retired. While baseload

generators are replaced with renewables, they are generally not available at full rated

capacity during extreme weather events and do not significantly contribute to capacity

during these periods.”15

V. The Challenges Facing Existing Nuclear Power Plants

Since a number of states restructured their electricity markets in the late 1990s, the business of

producing and transmitting electricity has evolved into two distinctly different enterprises.

In those states still subject to traditional cost-of-service regulation, companies and regulatory

commissions use the process of integrated resource planning to evaluate resource options on a

long-term basis, analyze project economics over a 40-year or 60-year time horizon, and assign

value to “public goods” like fuel and technology diversity and forward price stability.

Restructured merchant states have not yet developed mechanisms to value these “public goods”

and internalize them in their decision-making.

Fifteen years of experience with deregulated markets suggests that these markets are not

producing price signals sufficient to stimulate investment in new generating capacity (except for

gas-fired capacity), or to support continued operation of existing capacity.

Since 2013, four nuclear reactors (Crystal River 3 in Florida, San Onofre 2 and 3 in California,

Kewaunee in Wisconsin, and Vermont Yankee) have shut down permanently. Entergy

announced in October 2015 that it would close its Pilgrim plant in Massachusetts by June 2019,

and possibly sooner. In November 2015, Entergy announced that it would shut down its

FitzPatrick nuclear plant in upstate New York in late 2016 or early 2017. In May 2016, Exelon

announced that it planned to close two of its Illinois plants – the Clinton plant and the two-unit

Quad Cities station – in June 2017 and June 2018, respectively. In June, Omaha Public Power

District decided to close its Fort Calhoun nuclear plant, and Pacific Gas & Electric announced

the shutdown of Diablo Canyon 1 and 2 when their licenses expire. And there are other nuclear

plants at risk in addition to these.

Crystal River and San Onofre were unique situations that are unlikely to be repeated. Diablo

Canyon is the victim of aggressive state renewable and energy efficiency goals that would force

the reactors to operate only part of the time, thereby compromising their economic viability.

But Kewaunee, Vermont Yankee, Pilgrim, FitzPatrick, Clinton, Quad Cities, and Fort Calhoun

all fell victim to a combination of market-related factors (and, in some cases, a combination of

several factors), including:

Sustained low natural gas prices, which are suppressing prices in wholesale power

markets, and will continue to do so. In ERCOT, for example, the average gas price in

2015 was $2.57 per MMBtu, down roughly 40 percent from the 2014 average price of

$4.32 per MMBtu.16

In PJM, the load-weighted average real-time locational marginal

price (LMP) was 31.9 percent lower in 2015 than in 2014 – $36.16 per MWh versus

$53.14 per MWh. The average price in 2015 was about 20 percent lower than the

average of annual prices in all years from 1999 through 2015.17

Relatively low growth (in some markets, no growth) in electricity demand due partly to

subpar economic performance since the 2008 recession, partly to greater efficiency.

Federal subsidies and state mandates for renewable generation, which tend to suppress

prices, particularly during off-peak hours (when wind generation is highest and the

electricity is needed the least).

Transmission constraints, which require a power plant to pay a congestion charge or

penalty to move its power on to the grid. Certain nuclear plants at particularly congested

points on the grid pay a penalty of $6-9 per megawatt-hour to move their power out.

Market designs that do not compensate the baseload nuclear plants for the value they

provide to the grid, and market policies and practices – e.g., reliance on out-of-market

revenues – that tend to suppress prices.

This combination – which represents a unique combination of short-term, unsustainable factors –

is a “perfect storm,” which is forcing companies to make decisions in the short-term that do not

serve the long-term national interest.

Thanks to these factors, or a combination of them, some nuclear plants – particularly the smaller,

single-unit nuclear stations – operating in competitive markets are not able to recover their costs

from market revenues.

“Out of Market” Revenue for Renewables. It is worth noting, however, that wind and solar

facilities did not cover their costs out of the market either – but they had the advantage of other

sources of “out of market” revenue.

In ISO-New England, for example, “over 70 percent of the estimated net revenues for both wind

and solar units in the 2015/16 period were from federal and state programs, such as the purchase

of Renewable Energy Credits (RECs) and the Investment or Production Tax Credits (ITC or

PTC).”18

Similarly in the New York ISO: “A new solar PV project would have earned 58 percent to 69

percent of its 2015 net revenues from RECs and the ITC, depending on the location. Similarly,

Nuclear Energy Institute Comments on Quadrennial Energy Review 24

onshore wind units would have received 51 percent to 66 percent of their 2015 net revenues from

state and federal programs.”19

Needless to say, it is difficult for an unsubsidized nuclear unit to compete in these markets, given

the advantage conferred on other forms of carbon-free generating capacity and the price

suppression that occurs as a result of federal and state subsidies and mandates.

The Impact of Premature Nuclear Power Plant Shutdowns

Closing down a nuclear power plant has major impacts – on the environment, on consumers of

electricity (who will pay more for electric power in the long-term than they would if the nuclear

plant continued to operate), and on the states, counties and towns in which they are located.

A. Environmental Impact

The nuclear plant shutdowns that have already occurred, or that have been announced, are a

major setback for the Obama Administration’s Clean Power Plan, because the zero-carbon

nuclear energy has been, and will continue to be, replaced largely with gas- and coal-fired

generation.

Consider, for example, the shutdown in 2013 of Units 2 and 3 at the San Onofre Nuclear

Generating Station in southern California. According to a 2014 study by IHS Energy,20

closing

San Onofre made California power production more carbon-intensive. “The two nuclear units

were a major reason that the CO2 intensity of California power production was around 0.5

pounds (lb) per kilowatt-hour (kWh). Replacement power coming from in-state natural gas-fired

power plants has associated emissions of about 0.9 lb per kWh. Replacement power coming

from the rest of the Western Interconnection has associated emissions of 1.5 lb per kWh. Even

additional wind and solar power sources in California with natural gas-fired power plants filling

in and backing them up have a 0.7 lb per kWh emissions profile.”

In total, these reactors represent between 47 million tons and 64 million tons of increased CO2

emissions, depending on what sources of fossil-fueled electricity replace them (see table, next

page). As a point of comparison, the EPA’s analysis21

includes an estimate that the Clean Power

Plan will lead to CO2 emissions being reduced 82 million tons by 2020, so the loss of the

avoided emissions from the nuclear plants that have closed or are scheduled to close negates

more than one-half of this expected reduction.

In addition to this, companies have declared publicly that other power reactors are at risk, absent

action to recognize their value: Ginna and Nine Mile Point Unit 1 in New York, Davis-Besse

in Ohio, and Three Mile Island Unit 1 in Pennsylvania. Shutting down those plants would

increase carbon emissions by an additional 12 to 17 million tons, bringing the increase in carbon

emissions to between 59 million tons and 80 million tons. The higher number represents nearly

20 percent of the 414-million-ton reduction expected in 2030 under the Clean Power Plan.

The loss of nuclear generating capacity clearly compromises the Clean Power Plan goals, under

almost any set of assumptions and under any scenario.

B. Impact on Consumers

Closing a nuclear power plant – even one of the higher-cost single-unit stations like Kewaunee,

Vermont Yankee or Pilgrim – results eventually in higher electricity prices to consumers.

For example, the closure of the San Onofre Nuclear Generating Station resulted in higher

electricity bills. On top of an increase in carbon emissions of 9 million tons a year, California

consumers paid $350 million more for electricity in the year following the closure.22

It might be possible to find cheaper electricity off the grid for a short time – for as long as there’s

spare gas-fired combined cycle capacity, and spot gas available below $2 per million Btu, which

is clearly not sustainable.

later, that nuclear

capacity must be

of electricity from U.S. nuclear plants – the fleet average, the average for multi-unit plants (like

the Quad Cities plant scheduled for shutdown) and single-unit plants. The most costly nuclear

plants – the smaller single-unit stations – produced electricity, on average, for approximately $45

per megawatt-hour in 2014.

The blue bars show various estimates of the levelized cost of electricity from a new gas-fired

combined cycle plant – from the Energy Information Administration, from an integrated resource

plan filed recently by a regulated utility, and from Lazard. All are above – sometimes well

above – the cost of electricity from even the single-unit nuclear sites.23

The bottom line: It makes no logical sense to shut down a carbon-free $45-per-megawatt-hour

nuclear plant that provides 600-or-so direct jobs, and replace it with a $50-80 per-megawatt-hour

gas-fired plant that provides maybe 30 jobs and has roughly one-half the carbon emissions of a

coal-fired power plant.

Some New England states are looking north – to Canada’s untapped hydroelectric potential – to

satisfy their needs. Last year, Massachusetts Governor Charles Baker proposed legislation

authorizing the state to issue RFPs (requests for proposals) for an amount of power equal to one

third of Massachusetts’ total electricity use (and one sixth of New England’s power

requirements) each year for a 15-25 year contract period.

Based on published estimates of the cost of transmission and recent contracts between Hydro-

Quebec and New England utilities, The Analysis Group24

estimated that the cost of transmission

alone would be approximately $42 per megawatt-hour. “The electricity commodity cost would

be added on top of the ~$42/MWh. By comparison, this represents a significant share of

wholesale power prices in New England, which averaged around $55/MWh between July 2012

and June 2015 and which currently are around the same price (~$55/MWh) in forward power

markets in New England.” In total, then, the cost of Canadian hydro landed in Massachusetts

would be in the range of $97/MWh.

This is well above the $45-50/MWh electricity produced by Vermont Yankee or Pilgrim.

“This represents $777 million in above-market costs that Massachusetts consumers would be

paying every year,” according to The Analysis Group.

The bottom line: Productive nuclear generating assets are being retired, fuel and technology

diversity is being compromised, and electricity consumers are being exposed to long-term

reliability risks and price volatility. Market conditions are forcing companies to make decisions

that our nation will regret for the next 20 or 30 years, or longer, on the basis of short-term,

unsustainable price signals.

C. Not Nuclear Energy Or Renewables; Nuclear Energy And Renewables

It is unfortunate – and a profound disservice to a reasoned public policy discussion – that certain

individuals and organizations continue to assert that renewable sources of electricity can, and

should, replace nuclear energy as part of a national or international program to reduce carbon

emissions.

There is no credible analysis to support this assertion. In fact, independent analyses25

demonstrate unequivocally that nuclear energy, solar, wind and technologies to capture and

sequester CO2 will all be necessary to achieve meaningful reductions in carbon emissions.

Renewable sources of electricity clearly have an important place in a well-balanced generation

portfolio, particularly a portfolio designed to reduce carbon and other emissions. But renewable

sources are intermittent and do not have the same value to the grid as dispatchable baseload

resources like nuclear plants.

More to the point, renewables simple do not have – and may never have – the scale necessary to

replace existing nuclear plants.

In 2015, for example, America’s nuclear power plants produced 798 billion kilowatt-hours of

electricity. Wind and solar together produced 217 billion kilowatt-hours. So wind and solar

output would have to increase by 3.5 times, simply to match the output from U.S. nuclear plants.

Looking to the future, the Energy Information Administration’s Annual Energy Outlook expects

nuclear energy to produce 789 billion kWh in 2040. By then, EIA forecasts wind and solar will

25

Including the International Energy Agency’s World Energy Outlook, the United Nations Intergovernmental Panel

on Climate Change, the World Energy Council’s scenarios, and scenarios developed by such companies as Royal

Dutch Shell (see Appendix I for additional detail).

Nuclear Energy Institute Comments on Quadrennial Energy Review 29

produce 818 billion kWh. So it will take the next 25 years for wind and solar to catch up to

where nuclear energy is today.

The table above compares the electricity produced by renewable sources (the red bars) in several

states with the electricity produced by various nuclear plants in those states (the green bars).

These are all states where nuclear power plants have closed or where nuclear plants are at risk of

early shutdown. The data demonstrate clearly the enormous impact of closing a nuclear power

plant, and how difficult it would be to replace lost nuclear generation with renewables.

In New York, for example, loss of even a relatively small single-unit nuclear station like Ginna

would undo all the renewable development in the state. Closing the state’s nuclear facilities

“would eviscerate the emission reductions achieved through the state’s renewable energy

programs,” said New York Governor Andrew Cuomo last December, explaining why he was

ordering the state Public Service Commission to develop a Clean Energy Standard – and a

system of “zero emission credits” – to preserve New York’s nuclear energy assets.

When Vermont Yankee was closed in 2014, its generation was replaced by natural gas. Nuclear

generation in ISO New England declined by 5.3 billion kWh in 2015 compared to 2014 when

Page 30: Department of Energy’s...Jul 01, 2016  · Department of Energy’s (DOE) Quadrennial Energy Review (QER). The Obama Administration deserves great credit for recognizing the need

Nuclear Energy Institute Comments on Quadrennial Energy Review 30

Vermont Yankee was in operation. This fall was offset by natural gas use increasing by 5.7

billion kWh, and carbon emissions increasing by five percent in New England.

In Wisconsin, after Kewaunee closed, gas-fired generation increased by roughly two billion

kWh, coal-fired generation by 4.4 billion kWh.

In Illinois, the Quad Cities and Clinton plants produced about as much clean electricity in 2015

as all of the wind in Oklahoma and Kansas in that year. Quad Cities alone generated more non-

emitting electricity than all of the wind in California. This is not to diminish the importance of

wind energy: The broad deployment and technological advancements are an achievement worth

celebrating. But if wind energy is significant in meeting environmental goals, then so too is

preserving well-running nuclear plants. Under the Clean Power Plan, Illinois must reduce

carbon emissions by about 30 million tons by 2030. Losing Quad Cities and Clinton would

increase that compliance obligation by an additional 20 million tons a year.26

Existing Nuclear Plants: Least-Cost CO2 Reduction. Finally, the cost of avoiding carbon

emissions by preserving a nuclear power plant is significantly lower than other options,

particularly the other carbon-free options.

In its assessment of the New England market, the market monitor calculates the cost of reducing

CO2 emissions using various technologies.27

The results showed that:

a new combined cycle unit with access to gas priced at Iroquois Zone 2 would cost $30-

$32 per ton, depending on the efficiency of the unit.

Building a new onshore wind unit would cost $64-$68 per ton, excluding state and

federal subsidies.

Retaining a small, single-unit nuclear plant would cost $20 per ton.

Using utility-scale solar PV resources would cost $139 per ton.

The market monitor found similar results in its assessment of the New York ISO.28

Retaining

existing nuclear capacity in upstate New York would cost $20-$43 per ton. Using onshore wind

26

It is worth noting that the rate-based compliance approach embedded in the Clean Power Plan (CPP) would allow

Illinois to absorb the loss of nuclear capacity, replace it with generation from new gas-fired plants, and remain in

compliance with the CPP – even though CO2 emissions would increase. This is one of the serious structural defects

in the CPP. 27

and utility-scale solar PV resources on Long Island would cost $41 and $115 per ton,

respectively.29

29

These values for carbon-abatement cost apply to the Northeast. Regions of the country with different wind

regimes and solar insolation levels would have different values. But preserving existing nuclear power plants is

clearly one of the lowest-cost ways to reduce CO2 emissions. In its proposed rule for the Clean Power Plan, the

Environmental Protection Agency used these values: keeping “at risk” nuclear plants operating costs $12-$17 per

metric ton of CO2 abated; adding renewable capacity costs $10-$40 per metric ton of CO2 abated; increasing natural

gas combined cycle power plant utilization rates to 70 percent costs $30 per metric ton of CO2 abated; and

implementing demand-side management programs costs $16-$24 per metric of CO2 abated.

VI. Ensuring Continued Operation of Existing

Nuclear Power Plants: Policy Recommendations

To best serve the national interest, one of the top priorities must be to ensure continued safe,

reliable operation of as many of today’s nuclear plants as possible, for as long as possible, and as

long as continued operation makes economic sense. Achieving and sustaining meaningful

reductions in carbon emissions from the U.S. electric power sector will be difficult, if not

impossible, without the existing nuclear plants.

Market Design and Guiding Principles

There was nothing wrong with any of the nuclear plants that have shut down for market-related

reasons, or any of those at risk. Kewaunee, Vermont Yankee and others were all solid

performers – highly reliable plants with high capacity factors and relatively low generating costs.

When the Vermont Yankee nuclear plant closed at the end of 2014, it had just completed a 633-

day continuous run. The nuclear plants at risk in western PJM are producing in the low-$30-per-

megawatt-hour range.

For these plants, there’s clearly something wrong with the markets in which they’re operating.

The markets are not structured to recognize the value of the resources in place. They are not

operated so that all costs are reflected in prices. They are distorted by out-of-market revenues

and mandates.

The process of developing solutions to this set of problems must start with simple economic

principles. Goods and services will only be produced in a competitive market when they are

priced and valued in the market. It is also a mistake to think of electricity as an undifferentiated

bulk commodity. Every kilowatt-hour of electricity on the grid has a unique set of attributes,

depending on how it is produced.

So, for example, electricity generated from wind is carbon-free (a valuable attribute) but it is not

dispatchable and it tends to be correlated inversely with demand (the wind generally blows at

night when the electricity is needed the least).

Electricity from coal-fired power plants is dispatchable (a valuable attribute), and it has reserves

of fuel on site (another valuable attribute), but it’s not carbon-free.

On-site fuel supply, and the ability to run when needed, is a valuable attribute. It deserves

compensation. The New England ISO and PJM recognize this, with their “pay for performance”

and Capacity Performance capacity markets. Other ISOs have not yet evolved to that point.

Nuclear generating capacity has its own set of attributes, starting with production of large

quantities of electricity around the clock, safely and reliably. In some markets, even that value is

Page 33: Department of Energy’s...Jul 01, 2016  · Department of Energy’s (DOE) Quadrennial Energy Review (QER). The Obama Administration deserves great credit for recognizing the need

Nuclear Energy Institute Comments on Quadrennial Energy Review 33

not fully recognized because of the price suppression that’s occurring. Nuclear power plants also

provide forward price stability, and they have portfolio value, contributing to the fuel and

technology diversity that is one of the characteristics of a reliable, resilient electric sector. These

attributes are not valued. Nuclear power plants also provide clean air compliance value. This

attribute, too, is not valued. Nuclear power plants also provide reactive power – essential for

voltage support and frequency control – but the modest compensation for this service does not, in

many cases, fully reflect the value of this service.

In short, every kilowatt-hour of electricity on the grid has a distinct pedigree. If markets fail to

identify those attributes, incorporate them in decision-making, and value them in market design

and market policies, then companies will stop providing those attributes – and that, of course, is

what’s happening.

To achieve sustainable results, competitive electricity markets must satisfy the needs of

consumers, grid operators, electricity suppliers, asset owners and investors, regulators and

policy-makers. As Dr. Susan Tierney noted in comments in a 2013 FERC proceeding on

capacity markets: “We continuously expect our electric industry to solve a complex

‘simultaneous equation’ in which the countless decisions of myriad actors need to produce a

reliable, efficient and increasingly clean supply of electricity.” In Tierney’s view, the markets

today are not solving that ‘simultaneous equation’ correctly: “Something has to change for the

numbers to support a sustainable, healthy and vibrant electric industry capable of meeting system

operators’ technical necessities, consumers’ implicit needs, policy makers’ explicit demands, and

investors’ inherent requirements. That entire equation must be satisfied, or the system isn’t

sustainable.”30

Sustainable and effective market design demands appropriate consideration of all the factors that

constitute a robust and resilient market – including short-term prices, long-term price stability,

environmental factors, the portfolio value associated with fuel and technology diversity and

others. Although short-run cost is an important and necessary metric, solving this complex

equation for one variable only – i.e., lowest short-run electricity price – is unlikely to produce a

satisfactory result in the long-term.

Progress to Date

There has been movement on the part of the Federal Energy Regulatory Commission (FERC)

and a number of Regional Transmission Organizations to address some of the underlying

problems.

Supplemental Comments of Susan F. Tierney, Managing Principal, Analysis Group, Post-Technical Conference

Comments on Centralized Capacity Markets, January 8, 2014, Docket AD13-7-000.

Page 34: Department of Energy’s...Jul 01, 2016  · Department of Energy’s (DOE) Quadrennial Energy Review (QER). The Obama Administration deserves great credit for recognizing the need

Nuclear Energy Institute Comments on Quadrennial Energy Review 34

In 2015, for example, FERC approved a proposal from PJM to reform its capacity market to

provide additional compensation to generating resources – like nuclear power plants – capable of

sustained, predictable operation. These so-called Capacity Performance resources are expected

to be available and capable of providing energy and reserves when needed, and face substantial

penalties if they are not.

PJM held its first capacity auction – for the 2018-2019 delivery year – in August 2015 and two

transitional auctions in September. In all three auctions, the Capacity Performance resources

cleared at significantly higher prices than previous auctions that did not include a Capacity

Performance product.

There’s clear evidence that these market reforms work. They provided a short-term reprieve to

certain nuclear plants in 2015. But by themselves, they are not enough. Unfortunately, any

gains from Capacity Performance last year had been eroded by year’s end by the continuing

deterioration in the energy markets.

In the energy markets where baseload plants generate most of their revenue, accurate price

formation is absolutely essential. The goal here is relatively simple: Ensure that all costs

necessary to operate the system are reflected in locational marginal prices (or LMPs).

Transparent, accurate price formation breaks down when grid operators take actions that deviate

from least-cost dispatch. In such cases, system operators manually dispatch a resource that is

needed to resolve a constraint, or address a reliability concern, but those costs do not show up in

the clearing price. The RTOs provide make-whole payments, or “uplift” payments, to those

resources. This uplift tends to suppress price signals and inhibit accurate price formation.

FERC has developed an exhaustive record on price formation issues, starting with a series of

technical conferences in late 2014. Last September, FERC took a first step, with a Notice of

Proposed Rulemaking (NOPR) that would revise its regulations governing how the Regional

Transmission Organizations set prices in the energy markets.

The agency followed the NOPR with an order directing the RTOs to report back on how they

manage various price formation issues, including uplift. Earlier this year, FERC proposed

another change to its regulations in this area. The most recent proposal would change the policy

on offer caps, and would allow the RTOs to use the higher of $1,000 per megawatt-hour or a

cost-based offer.

FERC’s first step – the NOPR last September addressing settlement intervals and shortage

pricing – proposed two changes.

Page 35: Department of Energy’s...Jul 01, 2016  · Department of Energy’s (DOE) Quadrennial Energy Review (QER). The Obama Administration deserves great credit for recognizing the need

Nuclear Energy Institute Comments on Quadrennial Energy Review 35

The first would require that each RTO settle energy transactions in its real-time markets

at the same time interval it dispatches energy. Any misalignment between dispatch and

settlement intervals may distort the price signal.

The second change would require that RTOs trigger shortage pricing for any dispatch

interval during which a shortage occurs. There’s an obvious problem if there’s a delay

between the time when a system experiences a shortage and the time when prices reflect

the shortage condition.

FERC recently issued an order requiring the RTOs to implement the changes to settlement

intervals and shortage pricing. Although welcome, the two changes could be described as “low-

hanging fruit.” These are issues that influence the real-time market, but revenue to the baseload

nuclear units is determined in the day-ahead market. So closing the gap between day-ahead and

real-time markets is also essential.

And despite the progress, there is enormous reluctance in some quarters to acknowledge the

problems that have surfaced in competitive m markets over the last several years.

For example, in a recent white paper,31

PJM Interconnection declared: “No evidence suggests the

PJM markets inadequately compensate legacy units and thus are forcing a premature retirement

of economically viable generators.”

Ironically, the PJM white paper was published a day before Exelon announced that it would

close its Clinton and Quad Cities nuclear stations – two low-cost generating stations – because

the markets do not recognize their value.

Additional Steps Are Needed

The economic foundation under today’s nuclear power plants would be much stronger if the

United States had a meaningful, economy-wide program to reduce carbon emissions. Given that

such a program is both necessary and inevitable, the sooner it is in place, the better. For the

electric power industry, which makes 40- to 80-year investment decisions, certainty over an issue

like carbon is an imperative, and the continuing uncertainty over potential carbon regulations

makes long-term planning extremely difficult.

Continued operation of the existing nuclear plants would not even be an issue if there was a

meaningful price signal for carbon. Or, put another way, continued operation of the existing

nuclear plants would be assured if the nuclear plants’ carbon-free attribute was valued by the

market.

Nuclear Energy Institute Comments on Quadrennial Energy Review 36

Failing this, however, the federal government (including the Executive Branch, the Federal

Energy Regulatory Commission and the Congress), the regional transmission organizations and

the states have a sizeable inventory of options available to preserve existing carbon-free baseload

generating capacity. The inventory of solutions is significantly larger than commonly assumed,

and demonstrates that the challenges are not as intractable as frequently supposed.

Some of the options involve systemic changes to the policies, practices and protocols that govern

operation of the competitive markets. These should be accomplished quickly, whether or not any

power plants are at risk, because they represent necessary steps toward a more efficient market.

They will ensure more accurate price formation and appropriate valuation of the attributes

associated with each source of electricity.

Other options involve state government action to preserve valuable assets, or to maintain fuel

and technology diversity, or to ensure price stability.

The Nuclear Energy Institute provides this inventory simply to catalogue policy options that

could be addressed, if state and federal policymakers choose to do so. All the options listed have

a common denominator: They would help preserve existing nuclear generating capacity. Federal

and state policymakers must weigh the options based on their unique situations and

circumstances, and reach their own judgments about which approaches are most desirable.

One fact is certain, however: Policymakers cannot avoid taking action on one or more of the

items in this inventory, and likely other options not identified here, or the loss of carbon-free

baseload generating capacity will continue.

Federal and Regional Options

Competitive markets must fully value the attributes of existing nuclear plants, and the

services they provide to the grid. The competitive markets must continue the process,

already started to a limited extent, of identifying the services and attributes provided by

the nuclear plants, and developing mechanisms – either through the capacity markets or

the ancillary services markets – to provide compensation for those services and attributes

(like Capacity Performance in PJM or Pay-for-Performance in ISO-New England). In

addition, the Federal Energy Regulatory Commission (FERC) and the regional

transmission organizations (RTOs) must continue (with greater urgency than evidenced

to date) their ongoing efforts to ensure accurate price formation in energy markets.

FERC and the RTOs could consider additional reforms to capacity markets, including (1)

bifurcated capacity markets where zero-emitting resources are cleared separately; (2)

Page 37: Department of Energy’s...Jul 01, 2016  · Department of Energy’s (DOE) Quadrennial Energy Review (QER). The Obama Administration deserves great credit for recognizing the need

Nuclear Energy Institute Comments on Quadrennial Energy Review 37

longer-term (e.g., 10 or even 20 years) capacity products,32

and (3) separate markets for

as-available (intermittent) and on-demand (firm) power.

FERC and the RTOs must complete the ongoing reforms to policies and practices

governing the energy markets (the source of 80-90 percent of the revenue for a baseload

power plant). FERC recently finalized its proposed rule on shortage pricing and

settlement intervals.33

Prompt action is required to address remaining issues, including

offer caps and uplift.34

FERC and the RTOs could address the distortions occurring in the energy markets due to

federal and state subsidies and mandates. FERC has already determined that out-of-

market subsidies can harm capacity markets, and has approved a Minimum Offer Price

Rule (MOPR) or similar mechanism in each of the eastern RTOs to minimize the effects

of subsidies in capacity markets.35

Subsidies can also compromise competitive market

outcomes in the energy markets, and the Commission could take steps to ensure that the

value of out-of-market subsidization is not factored into markets for energy. Allowing

market participants to reflect out-of-market revenues in their bids into the energy markets

distorts and suppresses competitive price signals.

Congress could authorize investment tax credits or other tax benefits that would place

carbon-free nuclear energy on a level field with renewables like wind and solar.

The Executive Branch should revise the December 2013 Presidential Memorandum,

which ordered federal agencies to procure 20 percent of their energy from renewable

sources by 2020. That order should be revised to include carbon-free nuclear energy.

This might be particularly appropriate in light of the tripartite U.S.-Canada-Mexico

agreement to produce 50 percent of North America’s electricity needs from clean energy

– including nuclear energy – by 2025.

32

In ISO-NE and PJM, capacity products have a one-year term and a three-year time period between auction and

delivery. A one-year price signal three years in advance does not provide the pricing and investment certainty

necessary. The other RTOs generally have bilateral or shorter term centralized capacity markets or, in the case of

ERCOT, no capacity market. 33

The new rule would require that each regional transmission organization (RTO) and independent system operator

(ISO) settle energy transactions in its real-time markets at the same time interval it dispatches energy, and require

that each RTO/ISO trigger shortage pricing for any dispatch interval during which a shortage of energy or operating

reserves occurs. 34

Centralized power markets make uplift payments to generating resources whose commitment and dispatch result

in a shortfall between the resource’s offer and the revenue earned through market clearing prices. When the cost of

such payments are recovered through socialized uplift charges, energy prices are dampened. 35

See PJM Interconnection, LLC, 137FERC ¶61,145, in which FERC found: “Our intent is not to pass judgment

on state and local policies with regard to the development of new capacity resources, or unreasonably interfere with

those objectives. We are forced to act, however, when subsidized entry supported by one state’s or locality’s

policies has the effect of disrupting the competitive price signals that PJM’s RPM is designed to produce, and

that PJM as a whole, including other states, rely on to attract sufficient capacity.” (Emphasis added.)

Nuclear Energy Institute Comments on Quadrennial Energy Review 38

State Options

States could authorize long-term PPAs (power purchase agreements) to secure the output

from nuclear plants at prices that reflect their true value to the grid.

States could return certain nuclear plants to traditional cost-of-service regulation on the

grounds that they constitute critical infrastructure that is too valuable to lose because

price signals are distorted and prices are suppressed in the short-term by unsustainably

low natural gas prices.

States with renewable portfolio standards could modify them into zero-carbon or low-

carbon portfolio standards, and/or create a system of zero-emission credits (as New York

proposes to do) which explicitly credit nuclear energy as a carbon-free source, since

reducing carbon emissions is the main purpose of any such standard.

States could require load-serving entities under their jurisdiction to procure a balanced

and diversified portfolio of supply, including zero-carbon, dispatchable, baseload

resources.

Assuming the Clean Power Plan survives judicial review, the states could elect mass-

based compliance programs, covering both existing and new sources, which would

implicitly value carbon-free nuclear generating capacity.

Other Necessary Actions

In addition to market-

related actions to ensure

continued operation of the

nation’s nuclear energy

assets, a number of

additional steps are

necessary:

Ensuring a stable,

predictable regulatory

framework for second

license renewal. By

2030, several nuclear

power reactors in the

U.S. will have been

generating electricity

for 60 years and, by

Page 39: Department of Energy’s...Jul 01, 2016  · Department of Energy’s (DOE) Quadrennial Energy Review (QER). The Obama Administration deserves great credit for recognizing the need

Nuclear Energy Institute Comments on Quadrennial Energy Review 39

2040, half of the nation’s nuclear fleet will have turned 60. Second license renewal is

essential to sustain as much of this generating capacity as possible. The regulatory process

here is well-established, and the Nuclear Regulatory Commission (NRC) affirmed last year

that the existing process needs no revision. The industry, the Department of Energy (DOE)

and the NRC are conducting extensive research and development on managing aging issues

safely during a second 20-year license renewal period. The research has shown there are no

generic technical issues that would prevent a nuclear plant from operating safely beyond 60

years. Absent second license renewal, if all U.S. nuclear reactors shut down at 60 years and

are not replaced with new nuclear generating capacity, any gains from the Clean Power Plan

will be virtually eliminated (see figure, previous page). The Clean Power Plan will reduce

carbon emissions by 414 million tons in 2030. Replacing the lost nuclear capacity with new

gas-fired combined cycle plants will add back 356 million tons a year.

Providing a financial incentive to companies that pursue second license renewal. Preparing a

nuclear power plant for operation past 60 years will require capital investment – likely on the

order of $1 billion to $1.5 billion – to replace major components and systems and perform

other upgrades necessary to ensure safe, reliable operation. Some form of tax benefit – e.g.,

bonus depreciation or an investment tax credit – would provide a signal that these plants are

critical national assets and should be preserved. So would a Presidential mandate that federal

government agencies and installations buy a certain amount of their electricity from carbon-

free sources, including nuclear plants.

Continuing progress by the NRC toward a more safety-focused, more efficient regulatory

regime managed by a leaner, more effective agency.

Restructuring the used fuel management program – creating a new management entity to

operate the program, completing the licensing of the Yucca Mountain disposal facility, and

building one or more storage facilities until such time as a permanent disposal facility is

operating.

VII. New Nuclear Development: Priorities and Recommendations

As noted earlier in these comments, electrification and increasing reliance on carbon-free

resources is a worldwide phenomenon, and necessarily so if the world is to achieve meaningful

reductions in CO2 emissions.

Global Perspective

The Energy Information Administration’s 2016 International Energy Outlook, forecasts a 69-

percent increase in world electricity generation by 2040, from 21.6 trillion kilowatt-hours (kWh)

in 2012 to 25.8 trillion kWh in 2020 and 36.5 trillion kWh in 2040. “Electricity is the world’s

fastest-growing form of end-use energy consumption, as it has been for many decades,” EIA

notes. Electricity generation worldwide rises by 1.9-percent per year on average from 2012 to

2040, with the strongest growth in non-OECD countries. Increases in non-OECD electricity

generation average 2.5-percent per year … “as rising living standards increase demand for home

appliances and electronic devices as well as for commercial services, including hospitals,

schools, office buildings, and retail and grocery stores.” In the OECD nations, where

infrastructures are more mature and population growth is relatively slow or declining, electric

power generation increases by an average of 1.2-percent per year from 2012 to 2040.

In the world’s future, nuclear energy will play as important a role as it will in the United States.

The 2016 International Energy Outlook forecasts electricity generation from nuclear power

worldwide roughly doubling – from 2.3 trillion kWh in 2012 to 3.1 trillion kWh in 2020 and to

4.5 trillion kWh in 2040, “as concerns about energy security and greenhouse gas emissions

support the development of new nuclear generating capacity.”

If America wishes to retain its position as a world leader, it must lead this transition in energy

supply, not follow it. U.S. engagement in the world’s nuclear energy markets is essential, and

not just for commercial and economic reasons. Absent such engagement and leadership, the

United States will not be in a position to influence safety practices, regulatory frameworks or

nonproliferation policy around the world. America must begin to treat commercial nuclear

energy exports as an instrument of U.S. foreign policy, as a means of projecting U.S, influence

around the world, in much the same way as the U.S. government treats military sales.

U.S. Perspective

Planning for the long-term future of the U.S. electricity system – and the role of nuclear energy

in that system – must start by defining a reasonable and desirable destination.

It is not unreasonable to expect that, by mid-century, the U.S. electric grid will include a range of

reactors, varied in size, design and mission – the product of several decades of continuous

innovation. Some will make electricity around the clock. Others will produce electricity when

Page 41: Department of Energy’s...Jul 01, 2016  · Department of Energy’s (DOE) Quadrennial Energy Review (QER). The Obama Administration deserves great credit for recognizing the need

Nuclear Energy Institute Comments on Quadrennial Energy Review 41

it’s needed, as a critical component of an integrated low-carbon grid that also relies heavily on

intermittent renewable energy. Some will provide high-quality heat for chemical processing or

other industrial uses. Some will supply the transportation market, either with electricity to

charge batteries, or hydrogen or other chemicals to be burned in engines, in a system with a

vastly reduced carbon footprint. Some will make fresh water, or move water to where it is more

valuable. Some reactors will produce energy from the used fuel of light-water reactors and, in

the process, reduce the volume and toxicity of these materials.

The runway to that future is a continuum of developments, which starts with preservation of

America’s existing nuclear power plants (including second license renewal), proceeds through

construction of more large Generation III+ nuclear plants, then small modular reactors and,

finally, development, demonstration and deployment of advanced non-light-water reactors.

Allowing existing nuclear plants to close down prematurely because markets do not recognize

their attributes and value compromises – perhaps fatally – America’s ability to develop and

deploy the more advanced technologies.

Allowing existing nuclear plants to close down prematurely leads to loss of technical knowledge

and operational experience; erosion of the infrastructure that provides fuel, components and

services, and loss of political and corporate confidence in the technology – the foundation on

which the next generation would be built.

Conversely, failure to create a durable long-term program to develop and deploy new nuclear

plants and the advanced nuclear technologies makes preservation of the existing nuclear plants

even more difficult.

New nuclear plants and the advanced nuclear technologies are a magnet drawing the nuclear

enterprise toward a sustainable future in which nuclear power plants – of varying sizes and

designs – supply bulk electricity and a range of other products and services, and allow

integration of larger amounts of renewable energy than might otherwise be possible. A

promising future creates a compelling rationale for tackling challenges in the present.

In a short-term world of low-cost natural gas and no cost for releasing CO2 to the atmosphere, it

is counterintuitive and difficult to plan for construction of more large light water reactors and

SMRs, and development and deployment of even more advanced nuclear technologies. But

long-term planning is essential, and government and industry must both play their part.

A. Continued Deployment of Large Generation III+ Reactors

The first imperative is capitalizing on the lessons learned during construction of the new reactors

in Georgia and South Carolina. When Vogtle and Summer are completed and operating is

precisely the time for companies pursuing combined construction and operating licenses (COLs)

to move toward construction of additional plants – assuming, of course, a need for the electricity.

Page 42: Department of Energy’s...Jul 01, 2016  · Department of Energy’s (DOE) Quadrennial Energy Review (QER). The Obama Administration deserves great credit for recognizing the need

Nuclear Energy Institute Comments on Quadrennial Energy Review 42

For those

companies

AP1000 design, the

detailed design and

engineering will

have been

completed, thanks

to the Vogtle and

Summer projects,

thus removing a

major threat to cost

and schedule

certainty. In

addition, the

lessons learned

from these two

projects can be

applied

immediately to new projects, before too much time passes and those lessons are forgotten, in

both the regulatory process and in construction and startup activities.

Since the licensing process will have been tested on these first projects, and since the next

projects will have already received and banked their COLs for a design that is already certified, it

should be possible to reduce time-to-market to the time required for construction.

Companies must also satisfy themselves that new nuclear development makes economic sense.

Here there’s a big gap between the generating companies and what’s needed. Generating

companies today typically will not contemplate new nuclear development in a world dominated

by low-cost gas.

New nuclear capacity is closer to being economically viable than commonly assumed, however.

Lazard (see table above) puts the unsubsidized levelized cost of electricity from new nuclear

capacity in a range from $97 to $136 per MWh, with the plants now under construction in

Georgia and South Carolina at an estimated $124 per MWh. At the low end, this is much closer

than commonly assumed to the cost of electricity from a new gas-fired combined cycle plant.

(Lazard’s analysis assumes a long-term equilibrium natural gas price of $3.50 per million Btu.)

Other estimates of the cost of electricity from a combined cycle plant are directionally similar.

But Lazard’s estimates assume a traditional 50-percent-debt/50-percent-equity capital structure.

With a more leveraged capital structure (i.e., 80-20 debt-equity) and non-recourse project

Page 43: Department of Energy’s...Jul 01, 2016  · Department of Energy’s (DOE) Quadrennial Energy Review (QER). The Obama Administration deserves great credit for recognizing the need

Nuclear Energy Institute Comments on Quadrennial Energy Review 43

financing supported by a federal loan guarantee, the $124/MWh nuclear plant becomes an $80-

85/MWh plant, more closely competitive with the gas-fired option – and even more competitive

when accounting for the other attributes of a nuclear power plant, like carbon-abatement value,

forward price stability, and others.

So the most significant difference between a new nuclear project and a gas-fired combined cycle

plant is not cost. This is not to say that a nuclear project and a combined-cycle gas project are

identical. The nuclear project has unique licensing risks and construction execution risks. Time

to market is longer for the nuclear project. But cost of electricity produced is not the massive

impediment commonly assumed.

How, then, to manage the large risks associated with a new nuclear construction project? How to

move beyond the reluctance, on the part of any single company, to sponsor a new nuclear

project?

The answer: Divide the risks into manageable portions, and then fence off the risks from the

sponsoring companies’ balance sheets.

The major challenge for a new nuclear project is scale. These are large capital investments – $6-

7 billion for a new reactor – being built by relatively small companies. The U.S. electric power

sector consists of many relatively small companies, which do not have the size, financing

capability or financial strength to finance power projects of this scale on their own, in the

numbers required to reduce the electric sector’s carbon “footprint.”

Projects this large are not unique in the energy sector. In fact, $6-7 billion projects – and much

larger – are routine in the petroleum industry. Shell’s Prelude floating LNG facility offshore

Australia cost in excess of $10 billion. Chevron’s Gorgon natural gas project in Australia –

which includes production, gathering and liquefaction facilities – cost more than $50 billion.

Even the major oil companies, large as they are, seldom undertake major project development on

their own.36

They form project consortia to carve up the risk into portions they can readily

absorb.

New nuclear projects will require similar approaches: special-purpose entities to develop

projects, with financing support to manage the scale risk – to offset the disparity in scale between

project size and company size. For new nuclear projects, the federal loan guarantee program –

authorized in the 2005 Energy Policy Act – is an essential financing technique. Loan guarantees

have many benefits – they allow the industry to use project-finance-type structures, to employ

higher leverage in the project’s capital structure, and to fence off the project’s credit risk from

the project sponsor’s balance sheet.

36

Exxon-Mobil, for example, has a market capitalization of approximately $389 billion; Chevron Texaco, $198

billion. Southern Company’s market cap is $50 billion; Duke’s, $59 billion. (Data as of July 1, 2016.)

Page 44: Department of Energy’s...Jul 01, 2016  · Department of Energy’s (DOE) Quadrennial Energy Review (QER). The Obama Administration deserves great credit for recognizing the need

Nuclear Energy Institute Comments on Quadrennial Energy Review 44

Equally important, as structured in the 2005 Energy Policy Act, the loan guarantees are not a

subsidy, since the project sponsor pays the so-called “credit subsidy cost,” which reimburses the

government for the risk-adjusted cost of providing the guarantee.

Continuing deployment of large light water reactors like the AP1000 and the ESBWR

(Economic Simplified Boiling Water Reactor) will require a number of steps:

Develop innovative approaches to financing, project development and ownership, and

identify other policy changes (e.g., CWIP for wholesale nuclear plants in competitive

markets or tax-related benefits) that would support a more forward-leaning construction

program than is now contemplated. In addition to financing, new approaches to project

development and ownership should be explored – including, for example, formation of a

project development company, consisting of all companies interested in new nuclear

development or all companies committed to a certain reactor design, that would finance

and build new projects on a non-recourse basis, then sell them to a host utility when

ready for commercial operation.

The clean energy loan guarantee program, established in Title XVII of the 2005 Energy

Policy Act, is as important a risk-management tool today as it was when the law was

enacted. The Department of Energy should undertake an exercise, jointly with the

nuclear energy industry, to identify lessons learned from initial implementation of the

Title XVII loan guarantee program, including the reasons for certain projects abandoning

the program. For example, calculation of the credit subsidy cost was a major stumbling

block for certain nuclear projects. The industry believes that the most accurate and

equitable process for calculating credit subsidy costs is a detailed, project-specific

assessment. The approach used in 2009-2010, which relied on standard assumptions

applied to all technologies, with limited project-specific flexibility, cannot produce

accurate results, and will not serve the loan guarantee program’s objectives – to support

deployment of clean energy technologies in such a manner that the risk to the federal

government is offset by fees paid by the borrower.

In addition to lessons learned from past experience with the loan guarantee program, the

Department of Energy should prepare – no later than 2020 – for a significant addition to

its loan guarantee authority (or loan volume) to support additional large projects. The

existing loan guarantee authority (approximately $10.5 billion) will be quickly consumed,

and project sponsors must have certainty and line-of-sight to financing in order to

continue project development.

The Department should also consider changes to current practices – e.g., allowing project

sponsors to finance the credit subsidy cost (standard practice at the Export-Import Bank)

– and seek legislative authority to accomplish this, if necessary.

Nuclear Energy Institute Comments on Quadrennial Energy Review 45

Targeted revisions to the Atomic Energy Act are also necessary to produce a more stable,

more efficient licensing process, and to incorporate lessons learned during the licensing

and construction of the new Vogtle and Summer projects.

B. Development and Deployment

of Small Modular (Light Water) Reactors

In parallel with continued construction of large light water reactors will come first deployment of

small modular reactors (SMR) in the early to mid-2020s.

Small modular reactors are a major step toward greater flexibility – e.g., shorter construction

time, flexibility in siting, and possibly more manageable financing. Because of their small size

(typically 50-250 megawatts), they can be built in a factory and assembled on site, minimizing

field construction. An SMR facility will consist of several self-contained modules, so they allow

a utility to add new generating capacity in smaller increments, which may be particularly

valuable in a world where electricity demand is growing slowly. Financing may be easier, since

construction of an SMR facility does not require a single large $6-7 billion commitment: The

capital investment can be staged as modules are constructed. SMRs could be used to replace

older fossil-fueled generation facing new clean air requirements that are too costly to meet.

SMRs will be more flexible operationally than large nuclear plants, able to follow load. And

some will use dry cooling, minimizing water requirements.

To reduce the financial risk of the first movers and accelerate commercial deployment of SMR

technologies, the U.S. Department of Energy (DOE) launched a cost-shared industry partnership

program in early 2012. The DOE Licensing Technical Support program is funded on a 50-50

cost-shared basis by DOE and industry participants, with U.S. government support capped at

$452 million over six years.

This program – which will carry a single SMR design through NRC design certification – is

clearly not sufficient. A cost-shared program beyond the current DOE SMR program is

essential. That program must include a much larger federal financial commitment and larger

scope, including funding for at least two designs and design finalization beyond what’s necessary

for design certification.

Necessary next steps include:

The small modular reactor (SMR) program must be re-baselined to reflect realistic

expectations of cost and private sector capability. The Department of Energy and

Congress should increase support for small reactors beyond the current cost-share

program. Even doubling or tripling the size of the current program – from $452 million

to $1 billion or $1.5 billion – would represent a sound investment. DOE and the industry

Page 46: Department of Energy’s...Jul 01, 2016  · Department of Energy’s (DOE) Quadrennial Energy Review (QER). The Obama Administration deserves great credit for recognizing the need

Nuclear Energy Institute Comments on Quadrennial Energy Review 46

should also explore innovative approaches to close the funding gap, including use of the

Title XVII loan guarantee program.

Where appropriate, federal installations (like those operated by the Department of Energy

and the Department of Defense) should use their unique positions and resources to

advance SMR deployment – e.g., by serving as customers for the output. Options include

long-term power purchase agreements, favorable leasing agreements, and making sites

available. Discussions about federal facilities serving as initial customers for SMRs have

been going on for years. Analysis by several U.S. government national laboratories has

shown that this is feasible. The time has come to move beyond discussion and analysis.

C. Development and Deployment

of (Non-Light Water) Advanced Reactors

As the first SMRs start commercial operation in the mid-2020s, industry and government will be

building and operating the facilities needed to demonstrate the safety and commercial feasibility

of even more advanced designs. The goals:

Demonstrate two or more advanced non-light water reactors by 2025.

Ensure two or more advanced non-light water reactor designs are commercially available

(i.e., ready to build) in the U.S. by 2030.

Develop a licensing approach to facilitate deployment of these advanced technologies

and encourage continued private-sector investment.

Develop a business model that will support financing of the advanced technologies’

development, demonstration and licensing.

Advanced non-light water reactor designs offer many technological advantages – passive cooling

even in the absence of an external energy supply; operation at or near atmospheric pressure,

which reduces the likelihood of a rapid loss of coolant; consumption of nuclear waste as fuel; the

ability to adjust output to match intermittent sources of energy like wind and solar; and a larger

product slate, including process heat for industrial applications, hydrogen for automobiles, clean

water for human consumption and irrigation.

Advanced non-light water reactors come in various sizes, ranging from a few megawatts to over

1,000 megawatts. There are several advanced reactor technologies with great promise – molten

salt (in which the molten salt serves as both fuel and coolant); liquid metal coolants, which have

much higher heat transport capability than water, and thus provide a larger safety margin; and

high temperature gas-cooled reactors.

Page 47: Department of Energy’s...Jul 01, 2016  · Department of Energy’s (DOE) Quadrennial Energy Review (QER). The Obama Administration deserves great credit for recognizing the need

Nuclear Energy Institute Comments on Quadrennial Energy Review 47

The uncertainties associated with designing, testing and demonstrating, licensing, building, and

operating first-of-a-kind technologies are major challenges. As with light-water SMRs,

designing and licensing advanced non-light-water reactors is a capital-intensive proposition.

Due to the capital cost and long lifetime of a nuclear reactor, potential customers will likely want

to see a demonstration of any particular technology to prove technical feasibility and cost-

competitiveness.

Industry and government must address several major challenges to move successfully from

proof-of-concept and small-scale fuel and component testing (today) to commercial deployment

by 2030. Success requires a new licensing approach and a new platform to finance

demonstration and development. As with continued deployment of large light water reactors,

and development and deployment of SMRs, “business as usual” will not lead to success.

Licensing. Licensing conventional light water reactors is challenging and time-consuming.

Licensing an advanced reactor is even more challenging because the existing regulatory

framework is, understandably, based on light water reactor technology. The existing regulatory

structure is not designed to facilitate innovation or encourage private investment. The structure

must be modernized to establish a more technology-inclusive, risk-informed, performance-based

framework. The regulatory approval process must be staged – i.e., it must include meaningful

regulatory milestones that match investment decisions, to give investors confidence that the

technology will meet NRC safety requirements and can be licensed.

Financing. Developing a new approach to financing the demonstration and development of

these advanced technologies is also a top priority. In January 2016, the Department of Energy

awarded funds (up to $80 million over five years) to two consortia for advanced reactor

development. This was a good first step, but this traditional “business as usual” approach – a

government-industry program in which costs are roughly equally shared – will simply not work.

Neither the private sector nor the federal government will be able to raise the funds necessary.

As a rule of thumb, a demonstration reactor – necessary to demonstrate basic design and safety

concepts – can be expected to cost at least $1 billion.37

Sufficient design and engineering to

obtain a design certification from the NRC will add another $1 billion to $1.5 billion. The

detailed first-of-a-kind engineering – necessary to produce bid specifications and support an

engineering-procurement-construction contract – will add another $500 million. In all,

approximately $2.5 billion to $3 billion per design.

It is likely that there are two or three different designs – each with different capabilities and

attributes – with major commercial potential. This brings the total development and

37

This is likely unrealistically conservative. The 600-megawatt (thermal) demonstration project contemplated

under the NGNP (Next Generation Nuclear Plant) program was estimated to cost approximately $4 billion.

Page 48: Department of Energy’s...Jul 01, 2016  · Department of Energy’s (DOE) Quadrennial Energy Review (QER). The Obama Administration deserves great credit for recognizing the need

Nuclear Energy Institute Comments on Quadrennial Energy Review 48

demonstration cost to perhaps $9-10 billion. Even spread over 10 years ($900 million to $1

billion a year), this is much larger than any program currently contemplated. For example,

funding for advanced reactors in the 2016 fiscal year is $141 million. The Department of Energy

requested $109 million for FY2017.38

The Department’s budget request for FY2017 included a nuclear energy budget of approximately

$994 million. But the cost of operating and maintaining the Idaho National Engineering

Laboratory represents a little over 35 percent of that (or about $356 million). The proposed

budget for Reactor Concepts RD&D was $109 million, but that included $35.3 million for the

Light Water Reactor Sustainability program – a necessary and important program to extend the

lives of today’s reactors. That leaves only $73.5 million for advanced reactor technologies – a

long way from the $1-billion-per-year need.

Given the funding needs, in parallel with reforms to the NRC licensing process to accommodate

advanced, non-light-water technologies, industry and government must start immediately to

create a new, durable platform to finance advanced technology development. It is difficult to

imagine that the Department of Energy (or the private sector, for that matter) will be able to raise

the funds necessary to meet the challenge through annual appropriations.

Although the financing challenge seems daunting, the dollars required are not large by historical

standards. For perspective:

Between 1950 and 1962, the Atomic Energy Commission spent $26 billion (2010 dollars)

on nuclear reactor R&D.39

Between 1963 and 1975, the AEC spent another $33.7 billion

on reactor R&D (about 20 percent of its total spending of $163 billion). That’s $60

billion over a 25-year period. In the 12-year period between 1963 and 1975, nearly 25

percent of all reactor R&D funds ($8.2 billion out of $33.7 billion) was devoted to one

program – the liquid metal fast breeder reactor.

In 2040 the U.S. electric sector will generate 919 billion kilowatt-hours of coal-fired

electricity, according to the Energy Information Administration’s 2016 Annual Energy

Outlook. At a modest $10-per-ton carbon price, that coal-fired output would represent a

carbon cost of approximately $9.5 billion, in a single year (above and beyond what the

electricity might cost). At the social cost of carbon ($43.31 per ton), that coal-fired

output would represent a carbon cost of approximately $40 billion per year. That cost

would fall – every year – on consumers of electricity.

38

Senate appropriators raised that to $130 million; House appropriators, to $140 million. 39

Against this backdrop, the $9 billion to $10 billion cost of carrying several advanced reactors

through demonstration, through NRC design certification, to the point of commercial

deployment is a modest investment that would pay handsome dividends for all Americans.

VIII. Conclusion

NEI believes the Quadrennial Energy Review should begin by developing an inventory of the

challenges facing the U.S. electric power sector. These include:

The U.S. electricity sector is losing one of its major strengths – fuel and technology

diversity. A diverse portfolio of generating options is an essential characteristic of a

robust and resilient system. If current trends continue, that diversity is seriously at risk.

The United States is becoming overly dependent on one fuel – natural gas – for

production of electricity. This could expose consumers of natural gas and electricity to

price volatility and loss of reliability. Some parts of the country have already had

repeated warnings. Increased dependence on natural gas for electricity generation is

occurring at a time of growing gas demand for industrial uses and for export markets,

placing additional stress on the supply and delivery infrastructure for natural gas.

The merchant markets serving large portions of the United States are still – almost 15

years since restructuring and deregulation – not functioning as they should. The

competitive markets are not providing the price signals necessary to stimulate investment

in new generating capacity (except for gas-fired capacity), or providing the prices

necessary to support continued operation of existing capacity – including, in some cases,

nuclear generating capacity.

Significant changes in the electricity landscape are coming in the next few decades as

much of today’s generating capacity reaches retirement age. For example, between 2029

and 2055 all 100 operating reactors will reach 60 years of life. Replacing these facilities

with new ones, which will operate for 40 - 80 years, will be a capital-intensive, multi-

decade proposition.

NEI believes that preserving existing nuclear generating capacity, and preparing to build

relatively large amounts of new nuclear capacity in the next decade, are strategic imperatives.

Failing to do so would seriously compromise U.S. energy and environmental goals. A

continuing, growing contribution from nuclear energy is essential to produce needed baseload

electricity at stable prices and to sustain reductions in emissions of carbon and other pollutants.

In the world’s future, nuclear energy will play as important a role as it will in the United States.

The 2016 International Energy Outlook forecasts electricity generation from nuclear power

worldwide increasing from 2.3 trillion kWh in 2012 to 3.1 trillion kWh in 2020 and to 4.5 trillion

kWh in 2040.

If America wishes to retain its position as a world leader, it must lead this transition toward a

clean energy future, not follow it.

APPENDIX I

Independent Analyses Demonstrate that

Nuclear Energy is Essential for Carbon Reduction

Independent assessments of ways to reduce greenhouse gas (GHG) emissions worldwide have

concluded that no single technology can, by itself, slow and reverse increases of pollutants in the

atmosphere. A portfolio of technologies and approaches will be required to reduce carbon

emissions.

All these studies and analyses suggest that aggressive pursuit of energy efficiency and

conservation, renewable resources such as wind and solar, clean coal, electric vehicles, and

distributed resources must be accompanied by a substantial expansion of nuclear-powered

electricity generation.

IEA’s World Energy Outlook. In its 2015 World Energy Outlook (WEO), the International

Energy Agency40

(IEA) presents energy projections to 2040 under three different scenarios: (1)

the New Policies scenario, (2) the Current Policies scenario, and (3) the 450 Scenario (which

models what must be done to contain carbon concentrations in the atmosphere to 450 parts per

million of CO2-equivalent, generally considered the level necessary to hold global temperature

increases to 2 degrees C).

In both the New Policies Scenario and the Current Policies Scenario, world energy

demand increases substantially, fossil fuels continue to dominate the world’s energy

supply, and carbon emissions continue their upward trajectory.

In the Current Policies Scenario, nuclear energy production increases by 60 percent from

today’s levels (from 2.4 trillion kilowatt-hours in 2015 to 3.9 trillion kWh in 2040); by 88

percent in the New Policies Scenario (to 4.6 trillion kWh by 2040), and by 155 percent in

the 450 Scenario (to 6.2 trillion kWh in 2040).

The bottom line: In order to meet the 450 ppm target, production by nuclear power plants

worldwide must more than double. Nuclear generating capacity must obviously increase

as well – from 387 gigawatts (GW) in 2015 to 837 GW by 2040 in the 450 Scenario.

Intergovernmental Panel on Climate Change. Formed in 1988 by the UN’s World

Meteorological Organization and United Nations Environment Program, the Intergovernmental

40

The IEA is an autonomous organization within the Organization for Economic Cooperation and Development

(OECD) that works to ensure reliable, affordable and clean energy for its 28 member countries and beyond.

Nuclear Energy Institute Comments on Quadrennial Energy Review 52

Panel on Climate Change (IPCC) surveys and summarizes contemporary scholarly research in

several disciplines relating to climate change. IPCC’s Fifth Assessment consists of a Synthesis

Report and three Working Group Reports (on science, impacts and adaptation, mitigation). The

Working Group III report, “Mitigation of Climate Change,” published in April 2014, confirms

that nuclear energy is one of the lowest carbon-emitting technologies, and necessary to mitigate

the impacts of carbon emissions.

“No single mitigation option in the energy supply sector will be sufficient. Achieving

deep cuts [in emissions] will require more intensive use of low-GHG technologies such

as renewable energy, nuclear energy and CCS [carbon capture and storage].”

When the IPPC report accounted for direct emissions and lifecycle emissions, nuclear

ranked with wind energy at 12 gCO2/kWh.

The report’s “Summary for Policymakers” states that low-carbon technologies must

expand dramatically to curb the effects of climate change: “At the global level, scenarios

reaching 450 ppm CO2eq [consistent with a likely chance to keep temperature change

below 2 degrees C relative to pre-industrial levels] are also characterized by more rapid

improvements to energy efficiency, a tripling to nearly a quadrupling of the share of zero-

and low-carbon energy supply from renewables, nuclear energy and fossil energy with

carbon dioxide capture and storage (CCS) or bioenergy with CCS by the year 2050.”

The report found that, for a majority of low-stabilization scenarios, the share of low-

carbon electricity supply (renewables, nuclear and CCS) must increase from 30 percent

today to more than 80 percent of electricity generation by 2050.

EIA and EPA Analyses. Over the years, the Energy Information Administration and the

Environmental Protection Agency have analyzed the impact of various legislative proposals

designed to reduce carbon emissions. Although these legislative proposals – and the EIA and

EPA analyses – are now several years old, the climate goals in the American Power Act of 2010

(the so-called Kerry-Lieberman legislation) and the American Clean Energy and Security Act of

2009 (the Waxman-Markey legislation) are similar to those in President Obama’s June 2013

Climate Action Plan: a 17-percent reduction in carbon emissions from 2005 levels by 2020, and

deeper cuts in subsequent years. Both pieces of legislation also aimed for approximately an 80-

percent reduction in carbon emissions by 2050. EIA and EPA analyses of Kerry-Lieberman and

Waxman-Markey highlighted the essential role of nuclear energy.

Kerry-Lieberman – EIA’s analysis of the Kerry-Lieberman legislation (July 2010) concluded

that nuclear power would contribute 20-30 percent of electricity generation by 2035 (increasing

Page 53: Department of Energy’s...Jul 01, 2016  · Department of Energy’s (DOE) Quadrennial Energy Review (QER). The Obama Administration deserves great credit for recognizing the need

Nuclear Energy Institute Comments on Quadrennial Energy Review 53

from 891 billion kWh in 2010 to 1,463 billion kWh). EIA’s base case scenario projected that

72.3 GW of new nuclear capacity should be built by 2035 (52 new nuclear plants) and the

nuclear fleet would be generating 28 percent of U.S. power, slightly more than any other source.

EPA’s analysis forecast similar results: Nuclear energy was projected to generate 44.2 percent

of U.S. electricity in 2050, more than any other source. Total nuclear capacity was projected to

more than double from 101 gigawatts in 2010 to 256 gigawatts in 2050.

Waxman-Markey – EIA’s

analysis of the Waxman-

Markey legislation

(performed in August

2009) included a number

of model runs. The

“basic” scenario

represented an

environment in which low-

emission technologies,

including nuclear, fossil

with carbon capture and

sequestration, and various

renewables, are developed

and deployed on a large

scale in a timeframe

consistent with the

emissions reduction requirements of H.R. 2454. Under this scenario, the U.S. would need to

build 96 gigawatts of new nuclear generation by 2030 (69 new nuclear plants). This would result

in nuclear energy supplying 33 percent of U.S. electricity generation, more than any other source

of generation (see Table 1). In EPA’s analysis of the Waxman-Markey legislation, the primary

energy share of low- or zero-emission technologies (including carbon capture and sequestration,

renewable energy and nuclear energy) would increase from 14 percent, the current level, to 18

percent by 2020, to 26 percent by 2030, and to 38 percent by 2050. Without Waxman-Markey,

the clean energy supply percentage remains at 14 percent. EPA’s modeling showed that nuclear

generation would increase by 150 percent – from 782 billion kWh in 2005 to 2,081 billion kWh

in 2050. If all existing U.S. nuclear power plants retire after 60 years of operation, 187 new

nuclear plants would need to be built by 2050.

Clean Energy Standard – EIA also analyzed the impact of clean energy legislation proposed by

then-Sen. Jeff Bingaman (D-N.M.). Bingaman’s Clean Energy Standard Act of 2012 would

have required electricity retailers to supply a specified share of their electricity sales from

qualifying clean energy resources. The overall targets increased from 45 percent in 2015 to 80

percent in 2035 and remained constant thereafter. EIA found that the legislation’s goals could

only be met if, by 2035, nuclear power provided 30 percent of electricity generation (1,435

billion kilowatt-hours), with the construction of 81.3 GW of nuclear capacity (58 new nuclear

plants).

APPENDIX II

Canaries in the Coal Mine:

Previous Warnings About Natural Gas Dependence

In addition to continuing evidence of vulnerability in New England and this year’s Aliso Canyon

incident, major markets in the United States have had repeated warnings about what can happen

when states or regions find themselves too heavily dependent on natural gas – the Polar Vortex

in 2014, New England in early 2013, and Texas in February 2011.

The Polar Vortex

The extreme cold during the winter of 2013-2014 – the so-called “Polar Vortex” – caught the

attention of grid operators, power plant operators, load-serving entities and policy-makers alike:

Gas and power prices reached record highs. On January 6-7, 2014, spot gas reached over

$34 per million Btu (MMBtu) at the Algonquin city gate and over $55 per MMBtu at the

New York city gate; reached over $120 per MMBtu at the New York city gate on January

22, and approximately $50 per MMBtu in Chicago a week later.

PJM and MISO both experienced forced outage rates well in excess of average. Of

PJM’s 140,000 MW of generating capacity, 41,000 MW (almost 30 percent) was out of

service. Of that, almost 10,000 MW was gas-fired capacity that could not obtain gas at

any price; the rest, largely coal-fired capacity where coal piles or coal-handling

equipment froze. Of MISO’s 107,000 MW of generating capacity, almost 33,000 MW

was forced out of service – over 6,500 MW because it could not obtain natural gas.

New England in 2013

The New England region, which depends on natural gas for over 50% of its electricity supply

(almost double its dependence in 2000), found itself skating on thin ice several times in January

and February 2013, with reliability of electric service at risk and spot prices for natural gas and

electric power spiking dramatically.

In late January 2013, New England experienced the coldest five-day stretch since 2009 and two

weeks later, in February, a weekend blizzard left record snowfall across the region. The cold

stretch occurred Monday, January 21, through Friday, January 25, but no major power outages

were reported during this period and system conditions did not require ISO New England to

implement emergency procedures. The blizzard occurred Friday, February 8, and continued into

Sunday, February 10, knocking out power to more than 645,000 distribution customers,

Page 56: Department of Energy’s...Jul 01, 2016  · Department of Energy’s (DOE) Quadrennial Energy Review (QER). The Obama Administration deserves great credit for recognizing the need

Nuclear Energy Institute Comments on Quadrennial Energy Review 56

primarily in southern New England. Again, system conditions did not require the ISO to

implement emergency procedures.

The lack of more severe ISO actions, however, “was not a true indication of the volatility of

operating conditions that have persisted throughout the winter, severely testing the reliability of

the New England power system. These two events presented extreme challenges for ISO New

England system operators and the operators of power system resources across the six-state

region.”41

According to ISO New England: “High wholesale electricity prices … are an indicator of the

challenge, but do not explain the severity of the challenge, which is this: the region’s growing

dependence on natural gas for power generation is a rapidly-escalating strategic risk for the

region. This dependence on natural gas and the declining utilization of oil for power generation

have contributed to major reductions in oil inventories at power plants in the region. This risk

has already materialized in the ISO New England control room as operators must manage the

system in the face of growing uncertainty of the fuel supply for natural gas and oil-fired

generating resources—a condition that is unsustainable.”

These challenges have an impact on consumers of electricity. The total value of New England’s

wholesale energy markets from January 1 to February 20, 2013, was estimated to be about $2

billion. For comparison, the value of the energy market totaled about $5 billion for all of 2012.

ISO New England’s assessment of the situation is a plea for action: “This winter has

demonstrated that New England’s natural-gas dependency risk is escalating rapidly and that the

current fuel arrangements of generators, including the structural inflexibility of the fuel delivery

systems for oil and gas, is leading to extremely vulnerable and likely unsustainable operating

conditions when the power system and fuel-supply chains are stressed.”

Of greater concern, this was not the first such warning: “The ISO has documented the risk for

more than a decade through numerous reports and studies and in the past few years has identified

it as the highest-priority strategic risk for the region. This risk is not isolated to extreme cold

weather events, or even to winter events. The challenges—which are most acute during the

winter—are showing up in real-time system operations on an ongoing and year-round basis and

will threaten the reliability of the power system for the six-state region if not addressed in a

timely manner.”

Texas in 2011

As a major gas-producing state, Texas is (and always has been) heavily dependent on natural gas

for power production. This dependence cost the state dearly in February 2011, when extreme

cold brought the electric system to near-collapse. Because of the cold, a large number of power

plants failed and gas supply at the wellhead was interrupted by wellhead freeze-offs. Problems

with natural gas supply rippled into the electric sector, as a number of power plants could not

obtain fuel to operate. And problems on the electric side then propagated back into the gas

sector, as pumping stations, compressors and other key gas-related equipment lost power. At

one point, the Electric Reliability Council of Texas (ERCOT), which covers most of Texas, lost

one-third of its generating capacity. At various times between February 2 and February 4, 4.4

million Texans found themselves cold and in the dark.

The arctic cold front that descended on the Southwest during the first week of February 2011

was unusually severe in terms of temperature, wind and duration. The geographic area hit was

also extensive, complicating efforts to obtain power and natural gas from neighboring regions.

The storm, however, was not without precedent.

Going into the February 2011 storm, neither ERCOT nor the other electric entities that initiated

rolling blackouts during the event expected to have a problem meeting customer demand. But

193 ERCOT generating units failed or were derated, representing a cumulative loss of 29,729

MW. Combining forced outages with scheduled outages, approximately one-third of the total

ERCOT fleet was unavailable at the lowest point of the event. These extensive generator failures

overwhelmed ERCOT’s reserves, which eventually dropped below the level of safe operation.

Had ERCOT not shed load, it would very likely have suffered widespread, uncontrolled

blackouts throughout the entire ERCOT Interconnection.

According to a post-mortem prepared by the Federal Energy Regulatory Commission and the

North American Electric Reliability Corporation:42

“Generators and natural gas producers

suffered severe losses of capacity despite having received accurate forecasts of the storm,” says

the FERC-NERC assessment. “Entities in both categories reported having winterization

procedures in place. However, the poor performance of many of these generating units and wells

suggests that these procedures were either inadequate or were not adequately followed. The

experiences of 1989 are instructive, particularly on the electric side. In that year, as in 2011,

cold weather caused many generators to trip, derate, or fail to start. The Public Utility

Commission of Texas investigated the occurrence and issued a number of recommendations

aimed at improving winterization on the part of the generators. These recommendations were

not mandatory, and over the course of time implementation lapsed. Many of the generators that

experienced outages in 1989 failed again in 2011.”

“While extreme cold weather events are obviously not as common in the Southwest as

elsewhere, they do occur every few years. And when they do, the cost in terms of dollars and

human hardship is considerable.”
