Speaker: Terry MohnCompany: General MicroGrids
General MicroGrids General MicroGrids, Inc (GMI) is an end-to-end solution provider for renewable energy
technologies and transformational microgrid construction. GMI’s Balance Energy intelligent energy software platform “iESP”, manages microgrid
control, dispatchable renewable generation and resource control systems for campuses, industrial complexes, electric cooperatives, small communities and distribution utilities.
Safe, controllable and reliable MicroGrids integrating renewable generation are complimentary infrastructure with customer assets that increase grid reliability, stabilize long-term energy costs, and mitigate negative environmental impact.
GridWise Alliance The GridWise Alliance, founded in 2003, has developed into an organization that
represents a broad range of the energy supply chain from utilities to large tech companies to academia to venture capitalists to emerging tech companies.
This variety of stakeholders gives the Alliance a unique diversity of perspectives which enables interactive dialogue between members.
Being a consensus based organization; the assortment of opinions produces deliberate and highly reflected upon resolutions to key issues

Climate legislation is uncertain
Demand is increasing in spite of recession
Economic environment
The U.S. Energy Information Agency (EIA) estimates that renewable energy totaled 10.51% of all U.S. energy production at the end of 2009. The Administration states that it has created or saved 640,000 jobs since January 2009. This number includes roughly 51,700 new and 11,000 saved “green” jobs since January 2009.
The American Recovery and Reinvestment Act of 2009 (ARRA) created and expanded government financing opportunities, and to date marks the Administration’s single largest effort to promote renewable energy.
The Obama Administration’s stated mandate is to increase the renewable energy percentage of the U.S.’s total energy portfolio from 7.5% to 15%, and to create 5 million new renewable energy jobs, within 3 years of taking office (or by January of 2012).

Obama has commented that some sort of “price on pollution” – specifically on this “really bad thing for the environment” (GHGs) – would speed the development of U.S. jobs and deployment of cleaner energy resources.
Obama is leaving himself plenty of room to endorse any agreement which may arise from cap-and-dividend, net-zero carbon tax or other discussions, if they come together.
The FY11 White House budget proposal retained a place holder – but no details – for a regulatory structure for GHG emissions.
The American Clean Energy and Security Act of 2009, “Waxman‐Markey Bill” and the Clean Energy Jobs and American Power Act, “Boxer‐Kerry Bill”
Climate legislation looks increasingly unlikely to pass. It may be too politically controversial in an election year, and the mid-term elections are expected to complicate the legislative agenda. As such, more states may pass their own cap-and-trade legislation to supplement the 29 states already having such programs.
Congress may take up a new comprehensive energy package that would exclude climate provisions, but include tax titles, the creation of a Clean Energy Development Agency (CEDA, the so-called “Green Bank”), extensions of various ARRA programs, and some tax and non-tax incentives to promote energy efficiency and conservation.

PV SolarBioPower
NREL 2009 Report Since 2000, renewable electricity
installations in the United States (excluding hydropower) have nearly tripled, and in 2008 represent 42 GW of installed capacity.
Wind and solar PV are the fastest growing renewable energy sectors. In 2008, wind capacity installations increased by 51% and solar PV grew 44% from the previous year.
While the Legislature made several proposals to increase non‐wind generation, none of the proposals passed.
PURA 39.904(a) sets a target of having at least 500 MW of renewable generation other than wind.
Commission Staff issued a strawman rule proposal in Project No. 35792 on January 11, 2010.

Grid parity
Apr 4, 2010 - Chicago Tribune The key challenge facing developers is that existing transmission
lines, substations and transformers are inadequate to handle the amount of energy expected to come from wind farms
"It's easy to be green and say let's build wind but we have to think about - how are we going to deliver that?" said Thomas O'Neill, chief operating officer at Chicago-based Exelon Transmission Co., a unit of Exelon Corp.
The estimated cost to move that wind power east could range from $64 billion to $93 billion in 2009 dollars and would require 17,000 to 22,000 miles of transmission lines to be built in the eastern half of the country alone, according to National Renewable Energy Laboratory.
It isn't feasible for businesses to pay costs associated with the transmission upgrades. Many withdraw their requests to hook in once they realize the significant upgrades that would be needed, according to Midwest ISO.
Smart grid is new with many benefits
Communication infrastructure
Data privacy, security
Increased penetration of renewable energy into the generation mix
Technology upgrades within the utility New systemic impact occurring behind the
meter Distributed energy resources will likely
become the normal state; therefore, how do we integrate:◦ analog-centric power system ◦ digital-centric information infrastructure
Responding to these issues requires a new approach
“We’ll fund a better, smarter electricity grid and train workers to build it…” President Barack Obama
“To meet the energy challenge and create a 21st century energy economy, we need a 21st century electric grid…” Secretary of Energy Steven Chu
“A smart electricity grid will revolutionize the way we use energy, but we need standards …” Secretary of Commerce Gary Locke
“It is the policy of the United States to support the modernization of the Nation's electricity [system]… to achieve…a Smart Grid.” Congress, EISA 2007

Going greenPV, EV, Power MeterSustainability
Use of EV/PHEVs can help lower emission of pollutants, utilize less fossil fuels as the amount of wind generation in Texas grows, and help address energy security issues by reducing the amount of imported oil.
Powering a car on electricity would result in 93 percent less smog‐forming volatile organic compounds and 31 percent less nitrogen oxide emissions than powering a car on gasoline.
Operating costs of plug‐in cars are likely to be significantly lower than those of gasoline‐powered cars.
Electricity costs three to five cents per mile with average electric rates, or the equivalent of $0.75 to $1.25 per gallon of gasoline.
Consumer engagement with resources to solve power issues locally
Two-way power flow in distribution As prices increase, local renewables will
increase in residential, commercial, and industrial
Imperative to transform from passive to active control in distribution
New ways for distribution to become a transmission resource
Improved grid reliability “Green” alignment Improved energy use
and fuel costs Improved operating
