Washington Electricity

What Washington's Electricity Data Tells Us

Residential customers in Washington pay 11.90¢/kWh in 2024, spread across 3.4M metered households, placing the state 27.8% below the national residential average of 16.48¢/kWh. Commercial rates sit at 9.99¢/kWh while industrial buyers pay 6.61¢/kWh, reflecting the cost differentials that come from voltage level, load factor, and contract length across EIA Form-861 survey respondents. Annual residential sales total 38.6M MWh on roughly $4595.9M in utility revenue, a useful yardstick for sizing local demand against the grid mix that serves it.

The generation mix is led by hydro at 59.7% of in-state production, with natural gas providing 17.8% and nuclear supplying 9.8%. Renewable fuels, solar, wind, hydro, geothermal, and biomass, collectively account for 69.5% of Washington's electricity output, a figure that matters because each renewable megawatt-hour displaces fuel costs that otherwise flow through to retail bills. A portfolio this clean typically carries lower marginal generation costs once capacity is built, though transmission upgrades can offset part of the saving.

Looking back across EIA records, residential prices in Washington moved from 9.48¢/kWh in 2016 to 11.90¢/kWh in 2024, a 25.5% shift over that window. Comparable-priced neighbors include Louisiana, Utah, Oklahoma, which gives a peer set for sanity-checking local quotes. For anyone negotiating a supplier contract, weighing an energy-efficiency upgrade, or modeling a household budget, the combination of current rate, multi-year trend, and generation mix offers a sturdier footing than any single data point on its own.
