Washington electricity bills in context

The average monthly residential electricity bill in Washington is $130, ranking 40th among the 50 states and DC—closer to the middle than to the extremes. This bill is $25 below the national average of $155, or 16.4% lower. The difference comes from both directions: the price at 13.89¢/kWh runs 3.95¢/kWh below the national rate of 17.84¢/kWh, while homes use 65 kWh more per month than the national average of 871 kWh, pushing the bill upward. The pull downward from price is stronger, leaving the state well under the national figure.

Over the past year, since June 2025, the average bill has risen 9.7%, from $118 to $130. The longer view shows steeper growth: since May 2021, five years ago, the bill has climbed 32.9% from $98.

How this is calculated

EIA’s retail-sales dataset reports, for every state and month, total residential revenue and the number of residential customers served. The average monthly bill is simply the first divided by the second — total spending across all households, spread evenly over all accounts.

bill = revenue ÷ customers · averaged over 12 months (June 2025 – May 2026)

Two caveats worth knowing. It is an average, so it blends apartments with large houses — a typical household in Washington may pay well above or below $130. And it counts what was actually billed for electricity, including fixed service charges, so it is not the same as multiplying your own usage by the advertised rate.
