Being built
Homer City Energy Campus (gas power plant + Amazon data center campus)
Also called: Homer City Redevelopment, PIT100 Masterplan, AWS Homer City
The old Homer City coal plant is being turned into a huge gas power plant to run data centers. Amazon has filed plans for 39 data center buildings on about 2,200 acres in Center and Black Lick townships. The gas plant's air permit is being challenged by environmental groups.
Where things stand: Only the gas power plant is being built (first steel April 2026). The Amazon data center buildings are not approved yet. Amazon filed a master plan in Aug. 2026 and county review is pending. DEP says no state permit applications for the data centers have been filed.
🕒 Latest update (Aug 28, 2026): Amazon filed a master plan with the county for 39 two-story data center buildings on about 2,200 acres, built in six phases from December 2026 to 2036.
