Please share this communication internally within your organization with anyone who will be using PJM Tools Thursday, June 28, from 7-11 p.m. EPT (1900 to 2300 hours).

• Prior to the updates starting, please download any information you may need to access during the scheduled maintenance.

PJM is replacing the certificates for the majority of its PJM Tools URLs on pjm.com Thursday, June 28, from 7-11 p.m. EPT (1900 to 2300 hours).

During the upgrade time frame, those trying to sign in to PJM Tools may experience brief, intermittent outages.

Key Messages

• PJM is intentionally upgrading the certificates for PJM Tools on pjm.com to ensure uninterrupted data availability in the future for all our stakeholders.

• This is PJM’s second planned maintenance to replace the certificates that caused brief, unexpected outages during the May 24 replacement. Any member-facing issues that arose during that time were resolved. The certificates for the June 28 replacement have already been validated in advance of this upgrade to minimize the likelihood of an outage to PJM Tools beyond the scheduled upgrade time frame.
