Clean Energy Transformation Act (CETA) - Washington Department of Commerce
CETA (SB 5116) was implemented in May 2019. It commits Washington to an eletricity supply free of greenhouse gas emissions by 2045.
"CETA is a complex law requiring transformation of an essential service, electricity, and many agencies and stakeholders will work together to achieve its objectives. Commerce will work closely with the Utilities and Transportation Commission (UTC), which regulates the rates and service of investor-owned utilities. Other state agency partners include the state auditor and the departments of Ecology and Health.
More than 60 electric utilities must comply with CETA. Interested stakeholders represent business customers, low-income and vulnerable communities, consumers, environmental advocates and renewable energy developers." WA State Energy Office - WA Dept of Commerce
