RTS Brings Important Improvements to NYISO Systems
  • Co-optimization of energy and ancillary services
    fully meeting the intent of FERCs SMD
  • Better price convergence between day ahead
    commitment and real-time commitment and dispatch
  • Look-ahead features in RTC and RTD are important
  • Improvements in market flexibility, efficiency
    and reduction in uplift
  • Multiple transactions per hour
  • Two-settlement system for ancillary services
  • Real-time market power mitigation
  • More robust computer and communications
    infrastructure

Schedule
  • NYISO staff working intensely to maintain
    schedule
  • Massive tariff changes released for review during
    the last few weeks
  • Market participants have responded with
    concentrated review of scope and tariffs
  • Most controversial issue is the Reserve Demand
    Curve (RDC)

4
Reserve Demand Curve (RDC)
  • NYISO addressed reliability concerns
  • Reserve requirements will be met    
  • TOs expressed concerns on market power incentives
    and on setting and revising price levels
  • RDC-based prices when there were no physical
    shortages
  • Unwarranted spiking RDC prices at times of
    scarcity
  • Market power exerted to cause RDC to trigger high
    prices
  • NYISO responded comprehensively
  • NYISO response was well received
  • Not all concerns resolved yet
  • Market Advisor made a presentation to MSWG
  • TO involvement has been useful
  • There is a better understanding of RDC concepts
  • New protection measures have evolved

5
Reserve Demand Curve (RDC)
  • TOs confident that NYISO will address and resolve
    TO issues
  • There are concerns that RDC might result in
    excessive price levels
  • It is important to get this new function right
  • There is still time to constructively deal with
    remaining TO concerns within current schedule
  • NYISO to provide detailed justification of RDC
    price levels
  • NYISO to provide criteria for revising RDC prices
    up or down
  • TOs pledge to continue efforts to resolve
    concerns and still meet NYISO schedule
