Exelon Data Center Load Projections Drop Nearly 40 Percent

Exelon reported on July 30, 2026, that its high probability data center load fell from 18 GW at the end of the previous year to approximately 11 GW in the second quarter. The company attributed the nearly 40 percent decline to a strategic effort to weed out speculative projects through transmission security agreements (TSAs) designed to shield ratepayers from costs.

As part of this process, Exelon's subsidiary, Commonwealth Edison, canceled a TSA with PowerHouse Hillwood Holding on July 24. This action impacted a planned 1.8-GW, $20 billion data center in Joliet, Illinois. Additionally, the company's data center interconnection pipeline decreased from 43 GW in May to 25 GW.

To manage capacity needs within the PJM Interconnection market, Exelon's Atlantic City Electric subsidiary proposed a $1 billion, 500-MW battery storage system in Pittsgrove, New Jersey. Company leadership noted that the current market is failing to attract the level of new supply required by the system, even at the highest allowed prices.
