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

PJM Multi-factor Authentication Enhancements - Markets Gateway - October 19

10.19.2026 00:00 to 10.20.2026 00:00

PJM is upgrading the multi-factor authentication (MFA) process for all tools that use soft token-based authentication, including PJM.com. The following updates will take effect:

Enhanced device recognition framework will improve overall security, You will be prompted to complete MFA (soft token) more frequently, The soft token will expire after 15 minutes (reduced from 30 minutes) for enhanced protection

What Should You Expect? After this change takes effect, you will be asked to re-authenticate with a soft token on your next sign-in, Signing in from a new or unrecognized device will always require multi-factor authentication, After four invalid soft token attempts, the user account will be locked and must be unlocked by contacting their Customer Account Manager (CAM)

What Is Not Impacted? Applications and browserless transfers that use PKI-based MFA (Certificate based MFA) will not be affected by this change, PJM CLI and automated job transfers will not be affected

Impact on Automated Scripts Users who rely on automated scripts to log in to PJM.com and access or download files may experience script failures, as the login process will require manual entry of the soft token. The soft token will be sent to their registered email address.

Recommendations If the files being accessed are publicly available and do not require authentication, we recommend updating scripts to access the files directly without logging in to PJM.com. If you are unsure whether a file requires authentication, try accessing the file link without logging in to the website.
