Washington Net Metering and Efficiency Rebates by Utility

Utilities in Washington reported 69,352 residential customers on net metering in 2025, with 564.5 megawatts of capacity, which averages 8.1 kilowatts per customer. That is 20.4 customers per 1,000 homes. Among the 51 places that reported, Washington ranks 25th, and the national ranking is on the net metering by state page.

The value of a solar export depends on the credit your utility pays. As an illustration, take 7,000 kWh of solar power in a year, a made-up figure and not a forecast for any home. At the 2025 Washington average price of 13.17 cents per kWh, that power is worth $922 if the utility credits it at the full retail price. If the utility credits exports at half that rate, it is worth $461.

The gap shows why the export credit matters so much. Ask the utility which applies to you, and use the solar savings calculator to set the retail and export prices separately.

In 2025, 28 Washington utilities reported efficiency programs to EIA. Together they paid about $96,234,600 in incentives to residential customers, or $28.24 per home, which ranks 9th of 50. The programs reported 270,512 megawatt hours of first year residential savings, about 2.8 kWh for each dollar of incentive.

The IRS says the residential clean energy credit, which covered solar panels, does not apply to expenditures made after December 31, 2025, and the home improvement credit does not apply to property placed in service after that date. That is true in every state. What remains are state and utility offers, and the federal home energy rebates that states run. See solar incentives and home energy rebates.
