Warren Generating power station is a retired 84-megawatt (MW) coal-fired power station in Warren, the state of Pennsylvania, United States.

The current use of the Site includes the Warren Combustion Turbine (CT) facility owned by Warren Generation LLC.  The CT is a 57-megawatt natural gas- and distillate fuel oil-fired electric generating station, which consists of one operational simple-cycle CT and ancillary equipment and systems. Fuel for the CT is delivered by pipeline (natural gas) and tanker truck (oil). 

The Site previously had housed two coal-fired 42-megawatt steam electric generation units (Units 1 and 2), which were installed in 1948 and 1949, respectively, and retired in September 2002. Since the units’ retirement in 2002, all coal has been removed from the Site. 

Historically two on-site landfills were utilized: the North Disposal area, located northwest of the power generation facilities, was closed in 1984 via capping with native soils; and the South Disposal area, located west of the power generation facilities, was closed 2003 via capping with native soils. Waste materials placed in these landfills consisted of fly ash, bottom ash, and pyrites.  The South Disposal Area was operated under Solid Waste Permit No. 300858.  The Ash Pond Nos. 1 & 2 were closed in 2002-200 3.
