NYs Renewable Portfolio Standard (RPS)
  • 25 of energy retailed in NY should come from
    eligible renewable resources by 2013
  • Current level is about 19.5
  • RPS estimates that this need will be met by
  • 2,779 MW of NY-based Wind Farms
  • 1,350 MW of Imports (including 250 MW of Wind in
    PJM)
  • 294 MW of Biomass Co-Firing w/Coal
  • 121 MW of Landfill Gas
  • Initial RECs awards made to 7 renewable
    facilities 820,000 MWh contracted for 2006
    first-year payments estimated at roughly 18
    million

How Will RPS Impact System Reliability?
  • GE Energy Consulting engaged by NYSERDA and NYISO
    to evaluate reliability needs of RPS
  • Looked at 3300 MW of wind resources connected to
    NY system by 2008
  • Phase II study results released on Feb. 10, 2005
    available at www.nyserda.com/rps

Study Objective
  • To produce empirical information that will assist
    the NYISO in evaluating the reliability
    implications of the large scale integration of
    wind generation
  • Phase 1 Preliminary Overall Reliability
    Analysis
  • Phase 2 System Performance Evaluation

Study Findings Interconnection Req.
  • If state of the art wind technology is utilized,
    the NYSBPS can reliably interconnect wind
    generation on a large scale with only minor
    adjustments to its existing planning, operation,
    and reliability practices.
  • State of the art wind generators would have the
    following features/capabilities
  • Low-Voltage Ride Through
  • Leading/Lagging Power Factor Range
  • SCADA
  • Ratings of wind farms would need to be within the
    capacity of local transmission facilities and
    subject to congestion management
  • Power Curtailment Capability

Study Findings Capacity Value
  • Based on rigorous LOLP calculations using 2001 -
    2003 load and wind profiles
  • Inland Wind Sites
  • Capacity factors 30
  • Effective capacity, UCAP 10
  • Offshore Wind Site
  • Capacity factors 40
  • Effective capacity, UCAP 39
  • Developed approximate calculation method
  • UCAP On-Peak Capacity Factor for 100-500pm,
    June-August

Market-Related Wind Issues Schedule for Market
Participant Discussions
  • The NYISO is developing straw proposals
    addressing a number of market-related issues
  • Centralized wind forecasting system
  • Interim market rules clarification of 500 MW
    limit
  • End-state market rules
  • NYISO expects to discuss these proposals within
    the Market Structures Working Group in the
    July/August timeframe
