Real-Time NCPC

What is Real-Time NCPC?

Net Commitment Period Compensation (NCPC) is the "make whole" payment to an eligible Generator and/or external transaction that did not recover its offered costs from the Energy Market during an operating day. NCPC is determined by comparing the generator's energy offer costs with its actual revenue from the market for the day. Real-Time NCPC is calculated for Resources scheduled by ISO New England in the Real-Time Market. If the Generator does not fully recover its Real Time offer costs through the Real-Time Energy Market, a Real-Time NCPC payment will provide the cost recovery. If a Resource is partially Self-Scheduled in the Real-Time Market, any generation dispatched by ISO New England in excess of the Self-Schedule is eligible for NCPC. The complete set of rules for NCPC eligibility is detailed in Market Rule 1, Appendix F.
