Clean Energy Transformation Act

On May 7, 2019, Governor Jay Inslee signed into law the Clean Energy Transformation Act (CETA) (SB 5116, 2019), which commits Washington to an electricity supply free of greenhouse gas emissions by 2045. Clean electricity will allow Washington residents and businesses to power their buildings and homes, vehicles, and appliances with carbon free resources, such as wind and solar. Reductions in fossil fuel use will improve the health of communities, grow the economy, create family-sustaining jobs, and enable the state to achieve its long-term climate goals.

The law provides safeguards to maintain affordable rates and reliable service. It also requires an equitable distribution of the benefits from the transition to clean energy for all utility customers and adds and expands energy assistance programs for low-income customers. Commerce is a key leader in implementing this law. Working with utilities, other state agencies and multiple stakeholders, Commerce will develop rules, reporting procedures and regular assessments to ensure success.

Energy Assistance

Electric utilities must make energy assistance programs and funding available to low-income households and submit assessments to Commerce to inform a biennial report on energy assistance programs and funding levels.

Clean Energy Implementation Plans

Clean energy implementation plans (CEIPs) are four-year planning documents to meet the clean energy and equity requirements of CETA. Commerce collects CEIPs from consumer-owned utilities, and the State Auditor audits them for compliance with the law. The Utilities and Transportation Commission (UTC) collects and reviews CEIPs for investor-owned utilities.
