NYISO formed December 1, 1999 Independent board and management Highly divested and complex marketplace

featuring co-optimization market clearing systems

Most of the State’s generation is independently

  • wned

NYISO market volume was $10.7 billion in 2005

and $41.1 billion since inception

Unique challenge: New York City is world’s biggest

and most complex load pocket

Demand Response Program Overview Demand Response Program Overview

The NYISO operates two reliability-directed demand response programs:

  • The Emergency Demand Response Program (EDRP):
  • resources paid the greater of $500/MWh or the prevailing LBMP for

curtailments

  • no consequences for enrolled participants that fail to curtail
  • minimum 100 kW requirement – can aggregate resources
  • The Installed Capacity Special Case Resources Program (SCR):
  • certified resources can offer unforced capacity (UCAP) to Load Serving

Entities (LSEs).

  • resources are obligated to curtail when called upon to do so with two or more

hour’s notice, provided that they were notified on the day prior

  • resources are subject to testing to verify that they can fulfill their curtailment

requirement.

  • failure to curtail could result in penalties administered under the ICAP

program.

Participants register either for EDRP or ICAP/SCR but not both.

Distributed Generator Rules Distributed Generator Rules Proposed by the NY DEC Proposed by the NY DEC

  • 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 NYISO, NYPA, LIPA and Con Ed)

Characteristics of DG in NY Characteristics of DG in NY Demand Response Programs Demand Response Programs

To better understand emergency generator

participation in EDRP/SCR, the NYISO surveyed CSPs/RIPs in summer 2006

11 sponsoring organizations responded to

survey (out of 36 registered)

246 sources reported

96 sources surveyed are known to be generators in

NYISO records (39%) – 57.8 MW of ICAP

150 sources surveyed are not listed as generators

in NYISO records (61%) – 26.8 MW of ICAP

ICAP Markets in New York ICAP Markets in New York

ICAP Requirements are set for the upcoming

capability year

Load serving entities can meet their ICAP

requirements by:

Self-Supply Bilateral Transactions with Suppliers Forward Auctions Deficiency/Spot Market Auctions After-the-fact penalty procurement

slide-20
SLIDE 20

20

Locational ICAP Locational ICAP

Due to transmission constraints into certain

localities, areas or zones, some LSE’s must procure at least some of their ICAP requirements from resources electrically located within that locality

New York (NY) has had locational requirements

since inception. There are two such transmission constrained zones:

  • New York City and
  • Long Island
slide-21
SLIDE 21

21

Demand Curve Demand Curve -

  • NYISO Objectives

NYISO Objectives

Improve the traditional ICAP market Increase system reliability by valuing

additional ICAP above the NYCA and Locational Requirements

Reduce price volatility and send a more stable

revenue signal for new resources

Continue to ensure a competitive, fair, and

non-discriminatory market for capacity in the NYCA

slide-22
SLIDE 22

22

Demand Curve Spot Market Auction Demand Curve Spot Market Auction

Replaced previous Deficiency Auctions Uses a Demand Curve as a proxy for LSE Bids The Demand Curves are based on the cost of new

entry, with decreasing prices for ICAP above the NYCA or Locational Requirements

Conversely, the Demand Curve increases prices/value for

ICAP when resources are short of the NYCA or Locational Requirements Resources have the opportunity to supply ICAP above

the NYCA and/or Locational ICAP Requirements

Reduces stranded capacity

slide-23
SLIDE 23

Current NY ICAP Initiatives Current NY ICAP Initiatives

If accepted by FERC, implement mitigation

rules for NYC divested generators

Update demand curve parameters Expand ICAP Automation software Investigate need for and approaches to a

forward capacity market

Reflect FERC’s deliverability requirement in

the ICAP market once the FERC accepts the NYISO proposal
