Energy Capital Partners / Calpine Corporation. On-site at 828 MW gas turbine plant adjacent to Peach Bottom nuclear (Constellation/PSEG). Bundled with 51 community solar projects (24,000 homes). Tenant TBD. Energy Capital Partners announced a $5 billion data center to be built on the site of its subsidiary Calpine's York 2 Energy Center, an 828 MW dual-fueled combined-cycle gas turbine station in Peach Bottom Township. The project was unveiled July 15, 2025 at the Pennsylvania Energy and Innovation Summit at Carnegie Mellon, part of the more than $90 billion in state investments announced there by Sen. Dave McCormick with President Trump present. The York County Economic Alliance put construction employment at 2,500, and county leaders including President Commissioner Julie Wheeler and YCEA head Kevin Schreiber welcomed it publicly. The developer controls its own on-site generation, so the campus does not depend on new grid supply. The site sits near the Peach Bottom Clean Energy Center, the Constellation and PSEG nuclear station that employs more than 750 people and has sought a license renewal to 2054. As of early 2026 the project remained in pre-construction with no groundbreaking reported.

Know your rights
In Pennsylvania, a data center on industrial land usually needs a special exception or conditional use, decided by a local Zoning Hearing Board after a public, quasi-judicial hearing. Neighbors can request party status, cross-examine witnesses, and build an evidentiary record. Municipalities can also write data-center ordinances with enforceable standards.

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 ask your municipality for a moratorium and a real ordinance.
