Increased Reserve Requirements
  • Markets Gateway
  • Messages
No action required/information only

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
