In data centers, the power plant is now part of the real estate.
Homer City was Pennsylvania's largest coal plant. Its replacement is a gas plant that would supply the campus.
AWS plans 36 buildings, office and storage space, a substation and redundant generation.
Four phases run from Dec. 2026 to a final start in Jan. 2032, with completion in June 2036.
Estimated permanent jobs are 1,500 to 2,000; Knighthead Capital is helping finance the project.
Separately, Google's Constellation deals include a 2.7 GW, 15-year purchase across PJM not tied to a single plant.
Implications
The generation asset is now part of the site. A decade-long phasing schedule means land, power and permits are underwritten as one package, and the campus is only as certain as its gas plant.
Flags: This follows Oct. 7 coverage of ERCOT power timing; the angle here is PJM and onsite generation. The 8.1M SF total and 2.25x ratio are CRE360 derivations. DCD's description of one Constellation-related plant location appears inconsistent and is not used.
