- Developer
- FirstEnergy Corp. of Akron, Ohio, through its Pennsylvania utility, FirstEnergy Pennsylvania Electric Company, which covers the Met-Ed, Penelec, Penn Power and West Penn Power rate districts, and its transmission subsidiary, Mid-Atlantic Interstate Transmission. CEO Brian X. Tierney presented the Pennsylvania figure at the July 15, 2025 summit in Pittsburgh.
- Tenant
- This is a utility grid program that serves all customers, so there's no single tenant. FirstEnergy says its contracted data center demand reached 6.4 gigawatts company-wide in mid-2026, and its plan includes projects to support more data center load. FirstEnergy hasn't named Pennsylvania data center customers in the documents we reviewed.
- Current stage
- Work is underway across the territory, according to Sen. McCormick's office, which reported in July 2026 that grid upgrades are in progress. A $28 million transmission rebuild in Lehigh and Berks counties started in August 2025, and FirstEnergy planned to bring its $334 million Erie South to Piney line rebuild to the Public Utility Commission in summer 2026. The company-wide Energize365 plan grew to $36 billion for 2026 through 2030.
- Decision body
- The Pennsylvania Public Utility Commission sets FirstEnergy Pennsylvania's distribution rates, approves its quarterly infrastructure surcharge and its default power supply plans, and reviews new transmission line projects. PJM controls the transmission system's operation, and the Federal Energy Regulatory Commission regulates transmission rates.
- Top issues
- The main issue is what customers pay, since FirstEnergy Pennsylvania's base rates went up about $225 million a year in January 2025 after a request for about $502 million, and residential default power prices rose again on June 1, 2026 in all four rate districts as PJM capacity costs climbed. The other question is how much of the new grid work is driven by data centers and whether those customers pay for it, which the commission's 2026 large load tariff is meant to address.
- Key opponents
- No organized opposition group has been reported against the $15 billion program itself. In the 2024 rate case, the Office of Consumer Advocate called FirstEnergy's requested 11.3 percent return on equity "excessive," and state Sen. Lindsey Williams testified against the request at a public input hearing. In the commission's 2026 large load tariff proceeding, FirstEnergy pushed for a threshold of at least 200 megawatts, while the Office of Consumer Advocate and environmental groups, including Earthjustice, Sierra Club, Clean Air Council and PennFuture, mostly backed the 50 megawatt threshold the commission adopted.
- Key supporters
- Sen. Dave McCormick, who featured the pledge at his Energy and Innovation Summit, and the International Brotherhood of Electrical Workers, which is expanding an apprenticeship program with FirstEnergy. IBEW Locals 459 and 777 also signed the 2024 rate case settlement.
