FirstEnergy $15 Billion Pennsylvania Grid Expansion

56 of 67 Pennsylvania counties

FirstEnergy's pledge to spend $15 billion on its Pennsylvania grid, serving 56 of the state's 67 counties, is part of a $36 billion company-wide plan that's partly driven by data center growth, with distribution costs recovered from customers through rates set by the Public Utility Commission.

FirstEnergy's $15 billion Pennsylvania grid spending is underway

The number that mattersAbout $13 billion of FirstEnergy's $36 billion five-year grid plan is slated for Pennsylvania, according to the Erie Times-News.
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.

How we got here

2024: FirstEnergy Pennsylvania requests about $502 million in new annual revenue; the Office of Consumer Advocate and Sen. Lindsey Williams object. November 21, 2024: The Public Utility Commission enters its order in the rate case, and the settled increase of about $225 million a year takes effect January 1, 2025. July 15, 2025: FirstEnergy pledges $15 billion for Pennsylvania at the Energy and Innovation Summit. August 2025: Construction starts on the Allentown to Lyons to South Hamburg rebuild. February 3, 2026: FirstEnergy Pennsylvania files its default service plan for June 2027 through May 2031. March 2026: FirstEnergy outlines the $334 million Erie South to Piney rebuild. April 30, 2026: The commission adopts its large load model tariff. June 1, 2026: New default service prices take effect. July 2, 2026: A default service plan settlement is filed. July 28, 2026: FirstEnergy reports 6.4 gigawatts of contracted data center demand.

Update, October 26, 2026. On October 22, 2026 the Public Utility Commission took up exceptions to the recommended decision on FirstEnergy Pennsylvania's default service plan for June 2027 through May 2031, and its opinion and order was made public and served on the parties on October 26.

What is at stake

Impacts raised and open questions

Energy costs and the grid

High

FirstEnergy Pennsylvania's base rates rose about $225 million a year starting January 1, 2025 under a settlement of its roughly $502 million request,. The settlement bars a new general base rate increase before January 1, 2027.

Pennsylvania Public Utility Commission

Energy costs and the grid

Medium

Residential default service prices rose June 1, 2026 in all four FirstEnergy Pennsylvania districts, to about 13.95 cents per kilowatt-hour in Met-Ed, 13.14 in Penelec, 13.48 in Penn Power and 12.08 in West Penn Power, according to the company's PUC filing. ElectricityRates.com estimated increases of 6.9 to 11.9 percent and tied them mainly to higher PJM capacity costs.

Visual and light

Medium

The planned $334 million Erie South to Piney rebuild would run 82 miles from Summit Township in Erie County to Piney Township in Clarion County, replacing a 1950s line with steel monopoles built alongside the existing corridor. It needs PUC approval and a Pennsylvania Department of Environmental Protection stormwater permit, and construction is expected to take about four years.

Jobs and tax claims

Low

FirstEnergy said more than 40 new journey-level hires and apprentices would join its Pennsylvania team in 2025, tied to an apprenticeship expansion with the International Brotherhood of Electrical Workers.

Coverage of this project

Sources

Know your rights

In Pennsylvania, the local zoning ordinance sets the route. A conditional use is decided by the elected governing body (supervisors, commissioners or council). A special exception or variance, and an appeal of a zoning officer’s decision, go to the Zoning Hearing Board. Each is a public hearing on a record: affected neighbors can ask for party status, cross-examine witnesses, and appeal. Municipalities can also adopt data center ordinances with enforceable standards.

Take action

Organized community opposition is the single most effective check on these projects in Pennsylvania. Show up to hearings, submit comment when it is taken, support legal and expert-witness costs, and press your municipality for a real ordinance. Pennsylvania municipalities cannot simply freeze applications, but a curative amendment under the Planning Code gives them a defined window to fix a defective ordinance.
