Puget Sound Energy (PSE), founded in 1872 and headquartered in Bellevue, Washington, is the state's oldest and largest regulated utility. It supplies electricity to over 1.1 million customers and natural gas to more than 800,000 customers across 10 counties in the Pacific Northwest, serving residential, commercial, and industrial users alike.
PSE's core operations span electricity and natural gas distribution, with a service territory that covers a significant portion of western and central Washington state. As a regulated utility, its infrastructure investments and rate structures are subject to oversight by the Washington Utilities and Transportation Commission.
Beyond its distribution business, PSE has active programs in renewable energy, energy efficiency, and sustainable infrastructure - areas where it is directing capital investment as part of a broader shift in its energy mix. The company also runs energy equity initiatives aimed at ensuring that customers across its service territory can participate in the benefits of the clean energy transition.
Technology plays an increasingly central role in PSE's operations, spanning grid modernization, smart infrastructure, and the systems required to manage a more complex and distributed energy network across its 10-county service area.
