The Pennsylvania Department of Environmental Protection issued an air quality plan approval on November 20, 2025, allowing Homer City Generation to begin site preparation for the natural gas power plant at the 3,200-acre campus. Full construction is scheduled to start later in 2025, with electricity generation expected by 2027.
Former Homer City Power Station is set to become US’s largest natural gas-powered AI data center campus. Pennsylvania’s largest coal-burning power plant, the old Homer City Power Generating Station, is set for an unprecedented transformation. Located about 50 miles east of Pittsburgh, the site will be converted into a 3,200-acre natural gas-powered data center campus to serve the growing demands of artificial intelligence and high-performance computing.
Homer City Redevelopment (HCR) and Kiewit Power Constructors Co. collaborated to construct this innovative project, which will have seven gas-fired turbines generating up to 4.5 gigawatts of electricity—sufficient to power approximately 3 million households. Interestingly, the new plant should reduce greenhouse gas emissions by 60-65% per megawatt hour compared to its previous coal-fired operation.
GE Vernova (NYSE: GEV) will deliver seven high-efficiency 7HA.02 hydrogen-fueled gas turbines, with initial deliveries scheduled for 2026. Kiewit Power Constructors Co., a leading engineering and construction contractor, will oversee the construction process this missive Homer city data center campus .
“This project will acknowledge Homer City’s place in the proud history of Pennsylvania energy production, while accelerating the state and local community’s ability to meet the needs of a rapidly changing energy era,” said HCR President and CEO William Wexler.

Power generating facilities
The redevelopment rides on available infrastructures within the site, including transmission lines that are connected to the PJM and NYISO power systems, substations, and access. The construction of the power generating facilities will be initiated this year, while its power generation can be expected by 2027.
The build is a massive economic investment, with initial estimates in the $10 billion ballpark and potentially billions more to site prepare and construct data centers. The Pennsylvania state government has already awarded the project a $5M grant to move a gas line to the site, which is strategically situated over the Marcellus Shale natural gas reserve.
As part of the economic and energy benefits, the project is highly lucrative, with up to 10,000 job opportunities during its construction phase as well as nearly 1,000 permanent technological, operational, and energy-related jobs.
The Homer City project underscores Pennsylvania’s growing role as a major hub for large-scale data centers, highlighting the state’s ability to provide the infrastructure and resources needed for high-capacity computing. Pennsylvania already hosts some of the nation’s largest data centers, including Amazon’s $20 billion expansion to support its AI and cloud operations. Projects like Homer City reinforce the state’s strategic position in the data-driven economy and signal strong potential for future investments in both technology and energy infrastructure.
