PJM expects to have 182 GW of capacity ready to roll this winter—that’s plenty to meet the grid’s forecasted peak demand (a potential record of roughly 147.5 GW). But, the org noted, “reserve margins continue to tighten as demand outpaces new power supplies.” To ease grid stress, PJM is increasingly relying on demand-response programs.
Elsewhere: As we reported, MISO has secured 135 GW of capacity for winter, which is more than enough to serve its predicted seasonal peak of 113 GW.
Looking back: According to data collected last year, 99% of continental US winter capacity can operate in extreme cold, NERC noted in a recent report. That’s thanks to “ongoing industry efforts to strengthen winter preparedness,” the agency wrote in a statement, including ramped-up collaboration.
