PJM Power Auction Falls Short as Data Center Demand Surges

The shortfall emerged from the 2028/2029 Base Residual Auction, which procured 138,318 megawatts of capacity. While an additional 10,864 megawatts were secured through fixed resource requirements, the total remains below the threshold needed to meet the grid's one-event-in-10-year reliability standard. PJM, which serves 67 million customers across 13 states and Washington, D.C., now faces pressure to implement emergency procurement measures to bridge the gap.

Prices for the auction cleared at a FERC-approved ceiling of $325 per megawatt-day. Despite this cap, the cost of power remains volatile; internal analysis suggests that without regulatory intervention, prices would have been 70% higher. PJM CEO David Mills acknowledged the situation is untenable, noting that electricity demand is currently outpacing the development of new supply. The grid operator is now coordinating with the Federal Energy Regulatory Commission and state governors to address the deficit, with a special backstop procurement mechanism planned for September. This move aims to shift the financial burden of capacity expansion toward the hyperscalers and data center operators driving the rapid consumption growth.
