Clean Energy Transformation Act (CETA)

On May 7, 2019, Governor Jay Inslee signed into law the Clean Energy Transformation Act (CETA) (E2SSB 5116, 2019), which commits Washington to an electricity supply free of greenhouse gas emissions by 2045.

Clean electricity will allow the state to replace fossil fuels in other end uses, especially transportation, and achieve its long-term climate goals.

The Washington Department of 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.

Rulemaking Activities

Energy storage accounting issues

Commerce is delaying a request, issued on April 5, for written comments on energy storage. A new date and a list of questions will be published in a future CETA rulemaking bulletin.

Public hearing for phase 3 rules

Wednesday, April 28, 2021 

 1:00 p.m.

Commerce will be holding a public hearing on proposed rule to define two terms used in CETA: energy assistance need and low-income. The hearing is at 1:00 p.m. on Wednesday, April 28. The proposed rule defines energy assistance need as the amount of assistance necessary to achieve an energy burden equal to 6% of household income for utility customers. Low-income is defined as household incomes that do not exceed higher of 80% of area median income or 200% of federal poverty level, adjusted for household size. These definitions are the same definitions adopted by the Utilities and Transportation Commission. 

Written comments may be submitted to by the close of business Wednesday, April 28. The agencies will schedule a workshop on the topic after reviewing comments.
