Electric Companies in Washington: Utilities and Their Rates

Source: U.S. Energy Information Administration, Form EIA-861 (final 2025 data). Homes in WA counts only the customers in this state. Price and bill cover the utility's whole territory and bundled customers only. Delivery only means the utility carries power but does not sell it.

Each type is run differently. An investor-owned company answers to shareholders and a state commission. A municipal utility answers to a city. A cooperative answers to its members. That is why the same state can have very different prices and service from one address to the next.

Source: U.S. Energy Information Administration, Form EIA-861 (final 2025 data). Customer-weighted average of the prices utilities report for bundled residential service. It leaves out delivery-only customers and retail providers.

Outside the investor-owned companies, the largest municipal utility is Seattle City Light (472,309 homes), and the largest electric cooperative is Inland Power and Light (42,351 homes), and the largest public power district is Snohomish County PUD (349,905 homes).

Price differences between types come from costs, customer density and the way each type is financed, so a lower average does not decide which is better for your home.

These Washington utilities are among the 600 largest in the country, and each has a profile with its service area, reliability and rate options.
