Overview of Talk Overview of Talk

  • DR strategies and design principles in

wholesale markets

  • Elements of a “successful” DR program
  • Lessons Learned
  • ISO DR programs/markets
  • Related actions needed to support regional

DR programs

Wholesale Markets and DR Resources: Wholesale Markets and DR Resources: Objectives, Design Principles, Key Issues Objectives, Design Principles, Key Issues

Wholesale Market/ DR Strategy DR Program Objectives Design Principles and/or Key Issues Day-Ahead Energy Market (DADRP)

  • Increase competition

among suppliers

  • Put downward

pressure on day-ahead market clearing price

  • Ensure equitable treatment of supply and

demand-side resources while recognizing that Customer Loads are not Generators

  • Degree of Integration into ISO scheduling &

settlement processes “Emergency

Resources” (EDRP)

  • Restore system

security to design levels and help avoid load shedding

  • Resource value/pricing related to customers’

value of lost load Real-time Energy Market (RT Price Response Program)

  • Put downward

pressure on real-time market clearing price

  • Customers willingness/ability to respond with

limited notice

  • Degree of integration into ISO Scheduling

process Targeted Load Response for Constrained Area

  • Lower locational

market clearing price

  • Preserve transmission

grid reliability

  • Consider offering higher incentives to reflect

value of congestion relief

Defining “Success” in the Defining “Success” in the DR World DR World

  • Improve electric system reliability during

system contingencies: Potential & Actual performance

  • Improve efficiency of wholesale electricity

markets - demand-responsiveness

  • Broad portfolio of participating loads & program

types

  • High Penetration Rates in Target Markets
  • Effective coordination between ISO & retail

markets (LSE,PUC)

NEDRI Public Meetings: What do NEDRI Public Meetings: What do customers want in DR programs? customers want in DR programs?

  • Timely and certain payments for performance
  • Minimal downside risks (e.g. performance

penalties)

  • Relatively certain stream of benefits in order to

make “business case” for investment

  • Easy to enroll and participate (Low “hassle

factor)

  • Useful “toys”: enabling technology that can be

used to manage energy costs

  • Customized, tailored service offerings
  • Clear program goals that align with their

business interests or priorities

Characteristics of Innovative Utility Characteristics of Innovative Utility DR Programs DR Programs

  • Substantial customer response at high
  • ffer prices
  • Multiple program options & features
  • ffered under a single “brand”
  • LSE/customer share benefits (often not

transparent to customer)

  • Lots of customer care & education
  • Use of customer-specific baselines
  • Variety of forward contracting options
  • Motivated or “incented” LSEs

Real Real-

  • Time “Emergency” DR Programs

Time “Emergency” DR Programs

  • NEDRI recommendations on ISO-NE
  • higher minimum floor payments for called resources

(higher of RT LMP or $500/MWh minimum for 30 minute notice or $350/MWh for 2 hour notice)

  • reduce entry barriers for Demand Response

Providers ($500 annual fee)

  • a longer-term commitment to DR programs (3 years

starting with SMD; with option to extend)

  • Impact
  • Doubling of MW enrolled in ISO-NE “emergency” DR

program from 2002 to 2003 (112 to 260 MW)

  • Aug. 15, 2003: ~75 MW load reduction in SW CT for

10 hours

  • NYISO
  • Decent enrollment (~400 MW); few

accepted bids (~10 MW)

  • Location, location, location – most enrolled

participants upstate; highest need in NYC

  • NEDRI Recommendations for ISO-NE:
  • ISO-NE commit to developing an

“economic, price-driven” day-ahead market DR program by summer 2004, which draws upon “best practices”

Role of regulated utilities in delivering Role of regulated utilities in delivering ISO DR Programs ISO DR Programs

  • Policy and market implications to how ISO

payments are shared between providers and customers

  • NEDRI Recommendation
  • State PUCs adopt retail tariffs that support delivery
  • f ISO-NE DR Programs
  • 70% of ISO incentive payment for load curtailment

show flow to customer; 30% to be retained by regulated service provider

  • NY
  • 90% of payment passed on to customer

  • vercome DR market barriers
  • vercome DR market barriers
  • Significant market and institutional barriers limit

customer load participation in wholesale markets

  • Experience in selected states (NY, CT, CA) suggests

that small amount of SBC funds ($1-3M/yr or ~<5%) can increase DR infrastructure deployment significantly

  • NEDRI Recommendation
  • Additional funds to support DR enabling infrastructure,

technical assistance, and customer education/information. Funds should preferably be incremental to existing SBC funds, come from regional or state sources and be relatively small in amount

  • Enabling infrastructure includes: web-enabled EIS; advanced

Metering, communication and notification tech.; load control devices

Monitor and Limit Environmental Impacts of Monitor and Limit Environmental Impacts of DR Programs DR Programs

  • Issue: more frequent use of high-polluting

back-up generation

  • NEDRI Recommendations
  • Adopt output-based technology-neutral standards for

new onsite generators

  • Update state regulations for existing generators
  • Provide information base for envr. Analysis of DR

program impacts

  • 2003 ISO-NE Programs

Air regulators work with Demand Response providers

to develop user-friendly interface and process to expedite processing of permits and waivers

ISO-NE make info on actual load response events

available to air regulators to evaluate envr. impacts
