Puget Sound Energy

Puget Sound Energy (PSE) is Washington state's oldest local energy utility providing electrical power and natural gas primarily in the Puget Sound region of the northwest United States. The utility serves electricity to more than 1.1 million customers in Island, Jefferson, King, Kitsap, Kittitas, Pierce, Skagit, Thurston, and Whatcom counties; and provides natural gas to 750,000 customers in King, Kittitas, Lewis, Pierce, Snohomish and Thurston counties. PSE’s 6,000-square-mile (16,000 km2) electric and natural gas service area covers the largest metropolitan region north of San Francisco and west of Chicago. This area includes much of the more developed areas of western Washington State, excluding electrical service to the major cities of Seattle, Tacoma, and Everett, which are served by Seattle City Light, Tacoma Power, and Snohomish County PUD respectively. PSE shares effective control over electric transmission in the region with Bonneville Power Administration, which owns or controls much of the state's large transmission lines and hydro generation.
