PJM Interconnection’s “Summer Outlook 2026” predicts adequate electricity generation to power the region through a hot summer. However, the North American Electric Reliability Corporation’s “Summer Assessment” is more cautious.
While the standard reserve is 18.6 percent to cover a once-in-ten-years peak demand, PJM predicts a 26 percent reserve.
PJM anticipates a peak load this summer of approximately 156,400 megawatts, and will have 180,200 megawatts available to handle it, with another 7,800 megawatts contracted if needed. Last year’s peak was on June 23rd, when the demand was for 161,300 megawatts of electricity. The record demand was 165,563 megawatts in 2006.
In the report, PJM’s senior vice president of operations, Michael Bryson, says that while the grid operator for thirteen states expects “to operate reliably this summer, the outlook…reflects a new reality-continued load growth driven by data centers that is outpacing the addition of new generation.”
North American Electric Reliability Corporation has issued a Level-Three Alert, asserting that large computations loads such as data centers can behave differently than “traditional” electricity usage, and questioning whether electric utilities are prepared to meet the demand.
