Updates, newest first

  1. Oct. 20, 2026 DEP's tracker lists both an Amazon data center and a Homer City Redevelopment data center at the site as proposed, with no permit applications received. (Pennsylvania Department of Environmental Protection, Oct. 20, 2026)
  2. Aug. 27, 2026 Amazon Data Services filed a project narrative with Indiana County planning for 39 two-story data centers on six sites, built from December 2026 to 2036. (Indiana County Office of Planning and Development, Aug. 27, 2026)
  3. Dec. 17, 2025 Clean Air Council, PennFuture and Sierra Club appealed the air permit to the state Environmental Hearing Board. (PennFuture, Dec. 17, 2025)
  4. Nov. 18, 2025 DEP issued the air plan approval (No. 32-00457A) for the Homer City gas plant, seven GE Vernova turbines of up to 4.4 GW. (Homer City Generation (Business Wire), Nov. 20, 2025; Technical.ly, Nov. 19, 2025; PennFuture, Dec. 17, 2025)

Conflicts and open questions

  • Dates inferred: the Nov. 18, 2025 air approval date comes from Technical.ly's Nov. 19 story ('yesterday'); the approval number is from PennFuture's appeal release. The Amazon narrative carries no date; Aug. 27, 2026 is from its file name and PDF creation date.
