- Developer
- Energy Capital Partners announced the project through Calpine, which owned York 2. Constellation Energy bought Calpine on January 7, 2026, and must sell York 2 under the Justice Department's merger terms. Constellation announced on March 18, 2026 that it agreed to sell five PJM plants, Bethlehem, York 1, York 2, Hay Road and Edge Moor, to LS Power for $5 billion, with closing expected later in 2026 subject to regulatory approvals. It hasn't said what that means for the data center plan.
- Tenant
- Not disclosed. No end user has been named publicly.

- Decision body
- Peach Bottom Township Zoning Hearing Board, which would decide any special exception under Ordinance No. 2026-02, and the Board of Supervisors for any rezoning. The township says water withdrawals from the Susquehanna River and electric rates are regulated by state agencies.
- Top issues
- Water use and groundwater, noise, diesel backup generators and air quality, electric rates, farmland preservation, traffic, setbacks from homes and schools, and how little has been disclosed about the project or its end user.

- Key supporters
- York County President Commissioner Julie Wheeler called the announcement 'huge news for York County,' and York County Economic Alliance President and CEO Kevin Schreiber called it 'a massive investment in York County's economy.'
How we got here
Energy Capital Partners announced the $5 billion data center at Calpine's York 2 Energy Center on July 15, 2025, at the Pennsylvania Energy and Innovation Summit, and the York County Economic Alliance put construction employment at about 2,500 jobs. The 828 megawatt dual-fuel combined-cycle plant sits in the same township as the Peach Bottom nuclear station. Township supervisors said on November 5, 2025 and January 5, 2026 that no one had contacted or filed anything with the township. Constellation completed its purchase of Calpine on January 7, 2026, under federal terms that require selling York 2, and reported agreeing in March 2026 to sell five PJM plants to LS Power. Meanwhile the township wrote data center rules: the planning commission forwarded a draft on March 17, 2026, York County planners reviewed it in April and May, and supervisors adopted Ordinance No. 2026-02 on August 5, 2026.
