The bill adds new duties and authorities to "the department" (the specific department is not identified in the provided text) and amends an existing Growth Management Act provision (RCW 43.330.120). It creates new sections (Secs. 2–4) in chapter 43.330 RCW and clarifies the department's role as a central coordinator for state implementation of chapter 36.70A RCW. The change is primarily procedural and organizational: it establishes clean energy siting and development as a state priority and gives the department authority to assemble and share siting information, conduct planning and development functions for clean energy generation and manufacturing, support tribes and local governments, offer technical and financial assistance, provide alternative dispute resolution, and review compliance, subject to appropriations. The act authorizes the department, subject to available appropriations, to provide public information on clean energy technologies; work with the interagency clean energy siting coordinating council and other agencies to identify local best practices; support tribally led clean energy development and access to funding; develop guidance and templates for community benefits agreements and project labor agreements; support dual-use and agricultural colocation approaches through R&D and pilot projects; and assess tax provisions related to clean energy projects. It also permits the department to provide ADR services to resolve disputes among local governments, tribes, and project applicants, with tribal information kept confidential and exempt from public disclosure under chapter 42.56 RCW. The bill directs a focused battery energy storage work group (membership including tribal representatives, local governments, developers, regulators, emergency responders, and environmental justice interests) to address safety, emergency response, zoning, siting, and permitting for large-scale battery storage, to incorporate relevant nonproject EIS information, and to develop policy and regulatory templates. That work group must report findings and recommendations to the governor and legislature by July 1, 2026. Several authorities and activities in the act are explicitly subject to the availability of amounts appropriated. The statutory definition of "clean energy project" is referenced to RCW 43.158.010 but is not included in the provided text.

If enacted, a state department would become the central coordinator helping speed up and guide where and how clean energy projects get built, so cities and counties, tribes, and developers would get new state-provided tools: planning support, templates for community benefits and labor agreements, technical and financial assistance, and a confidential liaison for tribally led projects. That means local governments and tribes could see lower informational and negotiation costs and more options for dispute resolution, but the department will need funding to deliver these services and many activities are explicitly dependent on future appropriations. The bill also sets up a battery storage work group to produce safety, siting, and permitting best practices and a menu of policy options with a report due by July 1, 2026, which could make permitting and emergency planning more consistent for developers and first responders. Important details are missing, however: the text here does not name which department takes on these duties or specify funding levels, so how quickly and fully these practical changes happen is uncertain.
