Upcoming Changes

Increased Reserve Requirements

1.8.2026 00:00 to 12.31.2026 00:00

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 carried 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. Effective January 9, 2026 instead of 30% PJM will carry an additional 20% 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 20%

Synchronized Reserve requirement: 1,630*1.2 + 190 = 2,146 MW

Primary Reserve requirement: 1,630*1.2*1.5 + 190 = 3,124 MW

30-Minute Reserve requirement: Max(3,000, gas contingency, PR reliability) + 190 = 3000 + 190 = 3,190 MW
