This is a list of electricity-generating power stations in the U.S. state of Pennsylvania, sorted by type and name. In 2024, Pennsylvania had a total summer capacity of 48.9 GW through all of its power plants, and a net generation of 241,498 GWh. In 2023, the electrical energy generation mix was 58% natural gas, 30.3% nuclear, 7.1% coal, 1.4% wind, 1.1% hydroelectric, 0.8% solar, 0.6% biomass, 0.3% other gases, 0.1% petroleum, and 0.3% other. Small-scale solar, which includes customer-owned photovoltaic panels, delivered an additional net 1,479 GWh of energy to the state's electrical grid in 2025. This was about 20 percent less than the 1,882 GWh of generation by Pennsylvania's utility-scale photovoltaic plants.
The generating mix in Pennsylvania has been shifting from coal to gas, as in other U.S. states. Extraction of the state's fossil-fuel resources for domestic and foreign export sale ranked among the highest in the nation during 2019.
