This week, PJM issued a Capacity Advisory for Oct. 12–14 and escalated to a Maximum Generation Alert and Load Management Alert on Oct. 13, while recalling planned maintenance outages for Oct. 14. PJM attributed the tight conditions to unusually warm fall weather coinciding with significant planned generation and transmission outages, with roughly 62,000 megawatts of generation outages expected during the affected period. Outages of this scale are common for traditional thermal power generation during the fall season.
The U.S. Department of Energy also issued an emergency order for Oct. 13–16 that temporarily expands PJM’s ability to access additional generation, including, under specified emergency conditions, backup generators at data centers and other large commercial and industrial facilities. Ohio manufacturers participating in PJM’s demand response program may have been called to curtail this week during the alerts. 10/15/2026
