Due to the non-performance of committed Synchronized Reserve resources during Synchronized Reserve Events since the implementation of Reserve Price Formation (October 1, 2022) and to maintain compliance with NERC Standards, effective from May 19, 2023, PJM will carry an additional 30% on the Reliability requirement component of Synchronized and Primary reserve in the RTO only in the Day-Ahead, and Real-time Markets for all hours until further notice.
For example (rounded to whole MW): If the largest single contingency = 1,630 MW
Default (100% of largest contingency)
Synchronized Reserve requirement: 1,630*1 + 190 = 1,820 MW
Primary Reserve requirement: 1,630*1.5 + 190 = 2,635 MW
30-Minute Reserve requirement: Max(3,000, gas contingency, PR reliability) + 190 = 3,190 MW
Increased reliability by 30%
Synchronized Reserve requirement: 1,630*1.3 + 190 = 2,309 MW
Primary Reserve requirement: 1,630*1.3*1.5 + 190 = 3,369 MW
30-Minute Reserve requirement: Max(3,000, gas contingency, PR reliability) + 190 = 3179 + 190 = 3,369 MW
