The bill expands the authority of consumer-owned utilities in Washington State to enter into joint use agreements for the development, use, and ownership of electric generating facilities and transmission systems. It introduces provisions that allow cities of the first class, public utility districts, and joint operating agencies to engage in agreements with a wider range of entities, including those involved in renewable energy and energy storage. The bill mandates that each participant in these agreements must own a percentage of any common facility that corresponds to their financial contribution, and it introduces the concepts of joint ventures and limited liability company agreements. Additionally, it removes outdated provisions related to coal-fired thermal electric generating plants and clarifies the liability of participating cities, ensuring they are only responsible for their own actions.

Furthermore, the bill authorizes operating agencies to engage in various activities related to electricity generation and transmission, including contracting for necessary facilities and negotiating agreements with governmental entities. It allows joint operating agencies to enter into agreements with each other and with electrical companies, rural electric cooperatives, and other entities for the development and ownership of electric generating plants and facilities across various energy sources. The requirement for equitable ownership based on financial contribution is emphasized, promoting fair control over the electrical output generated by these facilities. The bill was passed by both the House and Senate in April 2025 and received the Governor's approval.
