Electricity Rates in Washington (2026)
National average: 16.72¢/kWh · Source: EIA, January 2026
Why Washington Has the Cheapest Electricity in the Country
Washington's electricity rates are the lowest in the nation, and the reason is hydropower. The Columbia River and its tributaries generate roughly 65-70% of the state's electricity through a network of federal and public dams, including Grand Coulee, one of the largest hydroelectric facilities in the world. Hydropower is extremely cheap to operate once built; the fuel (flowing water) is free. This structural advantage has kept Washington's rates below 12 cents per kWh for decades, even as rates in other states have climbed.
Public Utilities Keep Rates Lower Than Private Ones
Washington has an unusually high number of public utility districts (PUDs) and municipal utilities. Over 60% of the state's residents are served by publicly owned utilities, which operate as non-profits and pass savings directly to ratepayers. If you live in a PUD service area (common in central and eastern Washington), your rate may be even lower than the state average shown here. Seattle City Light, Tacoma Power, and Snohomish PUD are among the largest and cheapest utilities in the country.
Rates Are Rising, But From a Very Low Base
Washington's rates have increased roughly 15-20% over the past decade, driven by infrastructure upgrades, wildfire mitigation costs, and the addition of wind and solar to the generation mix. The state's Clean Energy Transformation Act requires 100% clean electricity by 2045, which will require significant new investment. Even with these increases, Washington is projected to remain one of the five cheapest states for electricity through at least 2030. A 20% increase on a 10.76 cent base still leaves you well below the national average.

Tips for Reducing Your Electricity Bill in Washington
- Take advantage of your low rates to electrify: heat pumps, electric water heaters, and EV charging are all exceptionally affordable in Washington compared to other states.
- If you are on a time-of-use plan (available from some Washington utilities), shift heavy usage like EV charging and laundry to off-peak hours for even deeper savings.
- Check whether your utility offers rebates for Energy Star appliances. Many Washington PUDs and municipal utilities have aggressive rebate programs that stack on top of already-low rates.
- Even at the nation's lowest rates, a space heater running 8 hours a day still costs about $39/month. Insulation and weatherization pay off everywhere.
Frequently Asked Questions About Washington Electricity
Hydropower. Washington generates roughly 65-70% of its electricity from hydroelectric dams on the Columbia River system. Once a dam is built, the operating cost is very low because the fuel, flowing water, is free. This gives Washington a structural cost advantage that most other states cannot replicate. Additionally, the prevalence of publicly owned utilities (PUDs and municipal utilities) means profits are reinvested into lower rates rather than distributed to shareholders.
The average Washington household uses about 950 kWh per month, resulting in a monthly electricity bill of approximately $100-$110 at the state average rate of 10.76 cents/kWh. This is well below the national average bill of about $148/month. Households in eastern Washington tend to use more electricity (electric heating is common) but also tend to have access to the cheapest PUD rates.
Rates are expected to rise moderately over the next decade as utilities invest in new wind, solar, and battery storage to meet the Clean Energy Transformation Act's 2045 deadline. However, Washington starts from such a low base that even a 25-30% increase over 10 years would still leave rates below the current national average. The transition away from the small amount of natural gas generation in the state will have a limited impact because hydro already dominates.
The payback period for solar in Washington is longer than in sunnier, higher-rate states like California or Arizona. At 10.76 cents/kWh, the value of each kilowatt-hour you generate is relatively low, and Washington's cloudy winters limit annual production. A typical residential solar system in western Washington might take 12-18 years to pay back, compared to 6-8 years in California. That said, net metering policies and federal tax credits can still make solar worthwhile if you plan to stay in your home long-term.
