Commercial electricity and gas rates, energy market structure, regulations, and utility providers for property managers operating in Washington.
Washington has a regulated electricity market with a mix of investor-owned utilities and public/municipal utilities. Seattle City Light (municipal) serves Seattle, while Puget Sound Energy serves many surrounding areas. The state benefits from abundant hydroelectric power, keeping base rates lower than national averages.
What this means for property managers:
In Washington's regulated market, your utility provides both generation and distribution at rates set by the state public utility commission. While you cannot choose your electricity supplier, you can optimize costs through rate schedule analysis, demand management, and participation in utility efficiency programs.
Rates are set by the public utility commission. No supplier choice available.
Stable
Hydroelectric generation keeps rates relatively stable, though drought years can cause spikes. Seattle City Light rates have increased modestly (4% in 2025) to fund grid modernization.
Washington's Clean Buildings Act (HB 1257) established the first statewide building performance standard in the nation, requiring commercial buildings over 50,000 sqft to meet energy use intensity (EUI) targets starting in 2026. Seattle has its own energy benchmarking ordinance requiring annual disclosure for commercial buildings over 20,000 sqft. The Clean Energy Transformation Act (CETA) requires all electricity to be carbon-neutral by 2030 and carbon-free by 2045.
