Historical Summary of EDRP/SCR Events
8
August 2, 2006
  • EDRP and SCR resources were activated in Zones
    JK from 1 pm to 7 pm, and Zones A, B C from 2
    pm to 7 pm.
  • Zone J activated for local reliability, K for
    forecast reserve deficiency, A,B C for Western
    NY area voltages
  • Record Peak Load 33,939MW
  • Fraser SVC and Leeds SVC taken out of normal for
    Oakdale and Ramapo voltage
  • 1,300MW of Emergency Energy to ISO-NE in HB13,
    ISO-NE in 5 voltage reduction
  • Emergency Transfer Criteria on the 91 92 lines
    (Leeds-Pleasant Valley) to support SENY PJM
    Transfers
  • Estimated performance by Zone
  • A 328 MW (300 MW SCR, 28 MW EDRP)
  • B 60 MW ( 59 MW SCR, 1 MW EDRP)
  • C 94 MW ( 80 MW SCR, 14 MW EDRP)
  • J 429 MW (334 MW SCR, 95 MW EDRP)
  • K 261 MW (174 MW SCR, 87 MW EDRP)
  • Total 1172 MW

Summary of 2006 Performance
  • 5 events called
  • 1170 MW (estimated) peak response on August 2
  • Submitted meter data is currently being processed
    for settlement
  • Demand response averaged roughly 2-3 of peak
    system load during this period

15
Developing Issues in DR
  • Emissions Impact of distributed generators NYS
    Dept. of Environmental Conservation
  • Demand side participation in ancillary services
    markets

16
Summary of Proposed DG Rules
  • The NYS Dept. of Environmental Conservation (DEC)
    has drafted rules (Part 222.1) that address
    environmental restrictions on the use of
    emergency generators in demand response programs.
  • Draft rules impose limits on MW registration in
    the NY metropolitan area (roughly Zones H-K) and
    elsewhere
  • NYCMA Upstate
  • January 1, 2007 271.9 MW 111.4 MW
  • January 1, 2011 150.0 MW 100.0 MW
  • January 1, 2014 50.0 MW 50.0 MW
  • 30-hour annual limit on use within sponsor demand
    response programs (including NYPA, LIPA and Con
    Ed)

17
Current Status
  • Proposed rule is being reviewed by NY Governors
    Office of Regulatory Reform
  • Will be open to public comment period following
    GORR review
  • NYISO is working with sponsors to develop
    registration process consistent with NYSDEC
    proposed rules
  • Rule needs to be implemented in a straightforward
    manner to avoid market uncertainty

18
Demand Side Participationin Ancillary Services
Markets
  • In early 2006, FERC ordered the NYISO to put in
    place the necessary software and rule changes to
    accommodate demand response participation in the
    ancillary service markets (spin and non-spin
    reserves, regulation).
  • The NYISO has been developing the functional
    requirements for such changes, with a deployment
    goal of Q3-2007.

19
Implementation Issues
  • Settlements
  • Payments for ancillaries / load reduction in
    response to basepoint signals
  • Metering
  • Real-time revenue-grade metering
  • Communications
  • Modeling
  • Full integration into Day-Ahead and Real-Time
    markets
  • Treatment of regulation providers
  • Operational Issues
  • Reserve pickup duration
  • Performance tests, impact on participation

20
Demand Response Whats on the Horizon?
  • Submitting meter response data in near-real-time
  • Automation of demand response activities
    registration to settlements
  • More targeted activations w/reflection in
    scarcity pricing
