Keystone Generating Station

The Keystone Generating Station is a 1.71-gigawatt (1, 711 MW), coal power plant in Plumcreek Township, Armstrong County, Pennsylvania. Occupying roughly 1,500 acres (610 ha) of land north of the community of Idaho, the plant sits along a bend of the Crooked Creek west of Shelocta. Built in 1967 and expanded in 1968, the plant has had a number of improvements to reduce the level of environmental pollution, especially measures to cut down acidic emissions of nitrogen and sulphur oxides. The station was scheduled to close by December 31, 2028 due to environmental protection regulations to reduce the amount of mercury, arsenic, and selenium the plant emits into nearby streams and rivers. However, the plant's operators and the Pennsylvania Department of Environmental Protection negotiated by Democratic Governor Josh Shapiro entered into a proposed consent decree to allow the plant and others in the state to remain in operation through 2032 subject to facility improvements to mitigate the environmental and health harm to the area.
