Date/Time of Change	Details	Duration of Impact
1.8.2026 - 12.31.2026 12:00 a.m. - 12:00 a.m.	Increased Reserve Requirements Tool/Website: Markets Gateway, Messages Impacts: Environment: Production Actions Required: No action required/information only, Please share within your organization 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: 1,6301 + 190 = 1,820 MW Primary Reserve requirement: 1,6301.5 + 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: 1,6301.2 + 190 = 2,146 MW Primary Reserve requirement: 1,6301.2*1.5 + 190 = 3,124 MW 30-Minute Reserve requirement: Max(3,000, gas contingency, PR reliability) + 190 = 3000 + 190 = 3,190 MW If you have any questions regarding this message, please contact PJM Customer Service at (866) 400-8980 or send an email to custsvc@pjm.com.
