PJM will conduct maintenance for PJM Tools login on Friday, July 19, from 10 a.m. to 6:30 p.m. EPT (1000–1830 hours). During this maintenance period, logging into PJM Tools (excluding PJM.com Corporate Website) may require re-authentication. This could potentially result in stale data on PJM's homepage, Markets & Operations, Planning Landing pages, PJM Now, Data Miner, and Data Viewer.
