Who generates Washington's electricity

Washington has 377 operable generating units on EIA's inventory totalling 28,973 MW of net summer capacity. The largest single plant is Grand Coulee , a conventional hydroelectric station operated by U S Bureau of Reclamation , rated 7,079 MW.

Balancing authorities keep supply and demand matched on the grid; the largest here by capacity are Bonneville Power Administration, Puget Sound Energy and Seattle City Light.

What Washington's Electricity Data Tells Us

Residential customers in Washington pay 13.11¢/kWh in 2025, across 3.4M metered households, placing the state 24.2% below the national residential average of 17.30¢/kWh. Commercial rates sit at 10.95¢/kWh while industrial buyers pay 6.88¢/kWh. These sector averages describe recorded revenue per kWh; this dataset alone does not establish why they differ. Annual residential sales total 39.0M MWh on roughly $5.1B in utility revenue. Sales and revenue are reported retail-series measures and should not be treated as a local load forecast.

Washington prices its sectors in step: 44 of 51 residential against 45 industrial. A state this consistent is the exception rather than the rule, and it means the residential figure above is a fair proxy for how the whole grid is priced. Hydro carries the majority of Washington's in-state generation at 63.6%, though not the whole grid: natural gas supplies 15.9% and wind a further 8.4%. It is the leading fuel in 4 states. Renewable fuels (solar, wind, hydro, geothermal and biomass) account for 73.4% of Washington's electricity output. These shares describe in-state generation, not a utility-specific customer bill.

Looking back across EIA records, residential prices in Washington moved from 9.48¢/kWh in 2016 to 13.11¢/kWh in 2025, a 38.3% shift over that window. States charging a similar rate include Oklahoma, Utah, Nevada, a useful peer set for a sanity check. Hydro is the one leading fuel whose availability is weather, not a purchase. A dry year in Washington means replacing water with something bought on a market, so the rate above is stable in ordinary years and carries a drought exposure no fuel contract can hedge. Read the number as a floor rather than a promise. A statewide average this far under the national figure is usually held down by a few large low-cost generators, and a household on the wrong side of a service-territory boundary in Washington can pay well above it.

Washington Average Price by Sector and Year (¢/kWh)

The chart above tracks households only. In 2025, Washington households paid 13.11¢/kWh while businesses paid 10.95¢/kWh, a 19.7% residential premium, a moderate household-versus-business gap. Every year EIA has published is below, so a single year can be read across all three sectors rather than assembled from three separate EIA queries.

Using Washington's numbers

A grid this renewable is close to the end of the supply-build phase, so Washington's rate is increasingly set by what it costs to keep power available in the hours renewables do not cover, not by adding more of them.

  • Washington sits 24.2% below the national average, see exactly where it lands among all 50 states. See the rankings
  • Check the multi-year trend before you judge the rate, a low price rising fast can cost more over a decade than a steady one. Washington price trend
  • Compare Washington side by side with the US average and peer states using the tool above, then estimate your own bill from your monthly kWh. Cost calculator

Figures are EIA state averages by sector, computed as revenue divided by sales, so delivery and taxes are inside them but not broken out. Your actual rate depends on your utility, plan, and usage, see our disclaimer.
