Washington Clean Energy Guide
Washington leads with hydroelectric power and is rapidly adding wind and solar to meet its 100% clean electricity mandate, one of the nation's most comprehensive clean energy laws.

Policy Overview
Washington's Clean Energy Transformation Act (CETA) is among the nation's most ambitious climate policies, requiring utilities to be coal-free by 2025, greenhouse gas neutral by 2030, and 100% clean by 2045.
The state benefits from Bonneville Power Administration's extensive hydroelectric system, while utilities are adding wind and solar to meet growing demand and replace retiring thermal generation.
Grid Operations
Washington is part of the Western Interconnection, with Bonneville Power Administration coordinating much of the transmission system. The state is exploring participation in regional market initiatives.
Active Projects
Wind Energy
Eastern Washington's Columbia Plateau hosts significant wind capacity, with ongoing development to meet CETA requirements and serve regional markets.
Battery Storage
Energy storage projects are being developed to balance hydro and wind resources and provide grid services during low-water periods.
