List of power stations in Oregon explained

This is a list of electricity-generating power stations in the U.S. state of Oregon, sorted by type and name. In 2022, Oregon had a total summer capacity of 17,243 MW through all of its power plants, and a net generation of 61,317 GWh.[1] In 2023, the electrical energy generation mix was 42.1% hydroelectric, 38.1% natural gas, 14.7% wind, 3.2% solar, 1.6% biomass, and 0.4% geothermal. Small-scale solar, including customer-owned photovoltaic panels, delivered an additional net 515 GWh to the state's electrical grid in 2023. This compares as less than one-third of the amount generated by Oregon's utility-scale photovoltaic plants.

During 2019, Oregon was one of the top-five U.S. states in its share of renewable electricity generation. It was the second largest generator of hydroelectric power after the state of Washington. Oregon ranks third in the nation behind California and Nevada for its geothermal generation potential.[2]

Nuclear power stations

The Trojan Nuclear Power Plant generated 1,095 MW of electricity during years 1976-1992.[3] Decommissioning and removal of the nuclear components was completed in 2006.[4] Oregon had no utility-scale plants that used fissile material as a fuel in 2019.
