Sources of Alaska utility-scale electricity generation, full-year 2023: [1]

  Natural gas (52.4%)

  Petroleum (13.5%)
  Coal (10.8%)

  Biomass (0.6%)
  Solar (0.1%)

This is a list of electricity-generating power stations in the U.S. state of Alaska , sorted by type and name. In 2022, Alaska had a total summer capacity of 2,820 MW through all of its power plants, and a net generation of 6,694 GWh. [2] The electrical energy generation mix in 2023 was 52.4% natural gas, 20.7% hydroelectric, 13.5% petroleum, 10.8% coal, 2% wind, 0.6% biomass and 0.1% solar. [1] The nation's only coal plant constructed since 2015 began operations in February 2020 at the University of Fairbanks. [3]

A grid known as "the Railbelt" serves about two-thirds of the state's population; extending from Fairbanks through Anchorage and into the Kenai Peninsula. Many of Alaska's power stations are diesel generators which service isolated communities and their localized transmission and distribution networks. Alaska is second behind Hawaii in the consumption of petroleum for electricity generation. The Alaska Village Electric Cooperative serves 58 communities in rural Alaska. Many rural residential customers receive the Power Cost Equalization subsidy to bring high electric costs closer to what urban residents pay. The state has vast untapped renewable resources, including wind near its coastlines, hydropower in its high-precipitation mountain regions, biomass from its forest and agriculture products, and solar from its rooftops.

Nuclear power stations

There were no utility-scale nuclear facilities in the state of Alaska in 2022. A proposed nuclear power station was the Galena Nuclear Power Plant.
