Mario DePillis and Bob LauritaINTERNAL MARKET MONITORING
Mitigation under NCPC Redesign
Synopsis
• Eliminating Day-Ahead General Threshold Mitigation
• Adding Manual Dispatch Mitigation
• Adding Manual Commitment Mitigation
• Start-Up and No-Load Fee Offer Limits (and Mitigation)
2
Manual Commitment and Dispatch
• Manual Commitment– Applies to manual decisions made by operators – Same low load cost test as other commitment mitigations
• Manual Dispatch– Applies if a resource is both manually dispatched and out
of merit– Out of Merit resources have LMPs below their offer for the
desired dispatch point (DDP) megawatts– Ends when resource becomes in merit or resource returns
to Eco Min
3
Commitment Mitigations
• The three types of commitment mitigation will use the same “Low Load Cost” test
• Low Load Cost test will be calculated using and commitment period known at the time of commitment as well as offer parameters and reference levels
• Duration of commitment mitigation is the duration of commitment period
4
Start-Up and No-Load Fees Overview
• Limited to 200% above reference level
• eMarket Bidding interface limit– Section III.A.6
• Standing offers (no bid made for the day) – Start-Up or No-Load Fees can become greater than 200% of Reference
Levels when fuel prices decline– Failure treated with mitigation – Section III.A.5.5.7.
