Avista Corporation operates primarily through two segments: Avista Utilities and Alaska Electric Light and Power Company (AEL&P). Avista Utilities provides electric distribution and transmission, as well as natural gas distribution services, across a 30,000-square-mile territory in eastern Washington, northern Idaho, and parts of Oregon. The AEL&P segment serves as the primary electric utility for the city and borough of Juneau, Alaska. The company's electric generation resource mix is heavily weighted toward renewable energy, particularly hydroelectric power, supplemented by thermal and wind facilities. Founded in 1889 as The Washington Water Power Company, Avista has grown into a diversified multi-utility focused on grid modernization and clean energy transition.
