existing dispatch filtering
Existing Dispatch Filtering
  • Filter prevents sending out dispatch instructions for small changes in scheduled quantities
  • New dispatch instructions issued for provision of energy change from the previous dispatch instruction provided greater than the lesser of 2% of maximum offer/bid capability and 10 MW
filtering enhancements
Filtering Enhancements
  • More adaptive filtering capability to help maintain adequacy and minimize CMSC that:
    • disables filtering of dispatch instruction within filter thresholds for:
      • energy resource dispatches to the facilities HIGH or LOW operating limit; and
      • energy reduction changes when previous dispatch instruction is > max. offer
filtering enhancements cont d
Filtering Enhancements cont’d
  • disables filtering every 30 minutes & prior to dispatch hour (intervals 1, 7 and 12)
  • permits filter thresholds to be energy resource configurable
policies procedures
Policies & Procedures
  • Enhance operational communication protocols & communication content involving the IMO, transmitters & connected marketparticipants
  • Potential changes to controlled rotational & U/F load shedding
  • Clarify procedures for emergency reduction of majorgenerating facility output to mitigate OSL after a contingency.
opsrp
OPSRP
  • Emergency Preparedness Task Force annual review of OPSRP - after the Nov. 26, 2003 exercise
  • Lessons learned from the Aug. 14 blackout
    • EPTF sponsored Restoration Working Group feedback - end of Nov.
opsrp cont d
OPSRP Cont’d
  • Reinforce need for key facility and critical component testing
  • Reinforce need for restoration plan market participants to open circuit breakers
control action breakers15
Control Action Breakers
  • By removing from service certain circuit breakers & eliminating the breaker failure contingency there are opportunities to improve transfer capabilities
  • This is required for TLR (TLR 4), but can also help to relieve interface congestion, enhance our ability to mitigate adequacy concerns, and provide additional transaction opportunities
  • Should this policy change be adopted it would require changes to market manual 7.4 and Appendix E “EOSCA list”
