Average electric bill in Washington

Over the last 12 months the average price was 14.20¢ per kWh and the average home used 927 kWh a month, so a typical Washington household spent about $132 a month on electricity, or $1,580 a year. Use is close to the US average of 875 kWh a month, peaking in January at 1,269 kWh.

The state average hides the real spread. Utilities in the same state charge different prices, and on a time-of-use plan the same kWh costs more in the peak hours than off-peak; each utility page shows by how much. Open PSE’s page to see its plans, prices by hour and fixed charge, or run the calculators below with Washington preloaded.

Natural gas for homes averaged $1.67 per therm over the 12 months to August 2026 (EIA, all charges included), and a typical gas-heated home uses about 557 therms a year for heating. The heat pump calculator compares that with electric heating on your plan.

A south-facing, 20° rooftop array in Washington produces about 1,060 kWh per installed kW a year (NREL PVWatts at the state’s population center). What that is worth depends on your utility’s export rule, shown on each utility’s page.
