Dimensions of Demand ResponseCapturing Customer Based Resources in New

England’s Power Systems and Markets

Connecticut’s Energy FutureHartford, CT

December 2, 2004

Americans have trouble managing energy demands

NEDRI Overview

Genesis: 1990s – Electric Restructuring underway in New England But Power shortages, price spikes of 1999-2001 – something

important is missing ! Regional load growth raises price, reliability and environmental

concerns Goal: balanced energy markets – regional scope Breadth: Remove market and policy barriers to all

customer-based resources: load response, energy efficiency, and distributed generation

Depth: Propose coordinated policies and programs for wholesale, retail and wires

New England can lead, provide a model

NEDRI Process: Key Points Sponsorship: ISO-NE, NECPUC, NESCAUM, NYISO,

DOE, EPA, FERC State + Regional + Federal agencies Utility + Environmental regulators Direct support and participation by FERC

Broad, Regional Stakeholder Participation: More than 30 stakeholder groups, including 3 ISOs, 6 state PUCs, utilities

and DR providers, DOE , EPA, state air directors, market participants, state energy offices, and advocates

Maine PUC and Public Advocate were active participants Working Groups developed recommendations for plenary review

Expert consulting team provided Framing Papers, technical support – great library of resources

Expert facilitation led to productive dialogue and consensus on almost all issues

NEDRI Approach: Four Themes

Broad view of DR: includes short-term response (load management) and long-term

(energy efficiency), pricing, and distributed generationExamine links in the market chain

Wholesale market rules, transmission tariffs, retail rate design Identify (and mitigate) barriers -

Reveal value of DR resources to customersAlign utility profits with cost-effective actionsSupport viable business models for DR providers

Challenge to ISO-NE, FERC and the states:Eliminate barriers to DR at wholesale, transmission, distribution, and

retailWork together to link retail and wholesale incentives, price signalsBe creative – we have unraveled the historic franchise, we need new

approaches to efficiency and reliability.

NEDRI’s Broad View of Demand Response Resources

“DR resources include all … modifications to the electric consumption patterns of end-use customers that are intended to modify the timing or quantity of customer demand on the power system in total or at specific time periods.” –NEDRI Report, p. 6

Includes responses to reduce capacity and/or energy required to serve load

Main types: Short-term load response, Long-term energy efficiency, On-site generation and CHP

NEDRI Conclusions and Recommendations

NEDRI Stakeholders adopted 38 recommendations; Almost all by consensus –

limited exceptions on options for transmission expansion and non-transmission alternatives

Organized into 5 substantive areas: Regional Demand Response ProgramsEnergy Efficiency as a DR ResourcePricing, Metering, and Default Service ReformDR for Contingency ReservesDR and Power Delivery (Transmission and Distribution)

Selected NEDRI recommendations—ISO’s Regional DR programs

NEDRI adopted numerous detailed recommendations for ISO Emergency and Day-Ahead/Price-based DR programs Higher minimum payments; capacity payments to enrolled resources Lower entry barriers, greater bid flexibility Longer term commitments (up to 3 years)

Many adopted by ISO-NE, ordered by FERC Demand Response Working Group established

Enrollment more than doubled, 2002 to 2003 (400MW+) Programs proved valuable restoring power after the August

2003 blackout: up to 130 MW load reduction, 90 MW average over 10-hour period

DR lowers the market clearing price – (so does efficiency)

Selected NEDRI recommendations– Energy Efficiency

EE-1: Ratepayer support for EE should be maintained, and potentially increased “to capture all cost-effective energy efficiency”

EE-3: New England states should adopt common model appliance/equipment standards for ten specific products – Better state and federal standards could displace 25% of load growth to 2020

EE-4: Update building codes and improve their implementation across the region –could displace 10% of load growth to 2020;

EE-6: Create a regional coordinating council for EE program design, cooperation, and assessment.

Demand Response includes embedded efficiency

Selected NEDRI recommendations – Pricing and Metering

PM-1: PUCs should investigate time-sensitive pricing for franchise and default service customers PUCs should bite the bullet and take a hard look at this. Pricing may vary by customer size and by availability of metering Options to consider include:

Real-time pricing Critical peak pricing Inverted block rates

PM-2C: Target efficiency to peak load uses PM-3C: Remove distribution company disincentives to

deliver aggressive DR programs. Mechanisms could include incentives, lost revenue adjustments,

revenue capped PBR

Selected NEDRI recommendations – Power Delivery

Key point: Strategic investments in DR can improve reliability, defer T and D upgrades

PD-4: (Planning process) Evaluate “on an even-handed basis” all reasonable solutions to grid needs: transmission, generation, and demand-response options (NEDRI consensus)

PD-6: (Regional investment policy) Majority view: “Efficient Reliability Rule” – only the least-cost,

reliable solution, (including demand response) is eligible for regional funding support;

Minority view: Regional funding should be available for transmission upgrades, but only for those upgrades;

Recent news: ISO announced “all-resources” bid for 5 years’ reliability solutions in SW Connecticut – including DR options

PD-7: Distribution companies should invest in DR resources that would improve reliability & defer more costly upgrades

What if the NEDRI Recommendations were implemented actively?

One post-NEDRI estimate:

Thus: Energy efficiency could offset 30-50% of incremental load growth And: DR and Pricing could provide an additional ~300 – 1800 MW of resources –Source: Lawrence Berkeley National Lab estimates (C. Goldman and G. Barbose), based on 2003

NEDRI Report after adoption, thus not reviewed or endorsed by NEDRI participants.

Progress to date Price-based and Reliability-based Demand Response:

ISO-NE creates Demand Response Department, hires highly-qualified director;

FERC orders adoption of NEDRI DR program designs – enrollment doubles;

States adopting output-based emissions standards for DG; DOE, ISO-NE, national labs studying use of DR for contingency

resources; Pricing and Metering:

NH PUC begins investigation of pricing and metering options; CT DPUC opens investigation into pricing and metering, including time

of use, seasonal, and efficiency-promoting rates VT DPS holding workshop on PRB to eliminate throughput problem

Energy Efficiency: CT joins Maryland in passing model appliance standards legislation—

which by 2020 will lower Connecticut power bills by a total of $380 million, lower peak demand by 126 MW and save 440 GWH annually.

Appliance standards bills moving in other states: VT, NJ, MA, ME Several states have recommitted to funding efficiency programs

Progress (con’t) Transmission and distribution:

National Grid pursues Brockton Pilot, other cases to study value of DR in deferring distribution upgrades;

VELCO applies “efficient reliability rule,” studies demand-side alternatives to transmission upgrade for NW Vermont;

ISO-NE (on CT’s urging) issues all-resources RFP for SW Connecticut reliability “gap” – but only limited demand-side resources enrolled.

Other: FERC orders NE RTO to create a new governance sector

for alternative resources, including DR; Certain NEDRI policy recommendations now under

deliberation in NYISO, PJM, and MISO.

Demand-side challenges for Connecticut

Connecticut is showing leadership and has taken some excellent steps: Appliance standards help create “critical mass” and inspire other states CEAB Energy Plan has many positive elements Resource-neutral RFP process for meeting energy needs is promising All-resources RFP for SW CT is a (half) step in the right direction

Ongoing challenges and opportunities: Critical value of energy efficiency funding – how to maintain ? Rate design investigation – many opportunities here Crucial need: reform the utility throughput incentive ! Can CT add efficiency to the resource mix in Standard Offer? What about delivering more accurate price signals through LMP zones in

CT, as in MA and NY ? Regional advocacy –

Can CT help the NE RTO to adopt resource-neutrality in system planning and expansion policies?

Can CT help Regional Greenhouse Gas Initiative to build pro-efficiency policies into the regional cap-and-trade program?
