Bill
SB 5466
Establishes a Washington Electric Transmission Authority to plan, fast-track high-voltage transmission upgrades, boosting reliability and clean energy delivery statewide.
Status and procedural timeline
- Introduced: January 23, 2025.
- Key actions: Passed the Senate (third reading) 03/10/2025; underwent multiple substitute and engrossed amendments in Senate and House committees in Feb–Apr 2025.
- Most recent action (04/27/2025): By resolution, returned to Senate Rules Committee for third reading. The bill has several competing amendments still reflected in committee reports.
Purpose and legislative intent
- Establish a statewide entity to plan, develop, coordinate, and accelerate upgrades and expansion of high‑voltage electric transmission to support Washington’s clean energy and reliability goals (carbon neutral by 2030; carbon‑free by 2045).
- Address growing electricity demand (electrification, data centers, manufacturing), resilience to extreme weather, and access to regional renewable resources.
Core provisions (common to principal bill versions)
- Creates a new state body — various drafts call it the Washington Electric Transmission Authority (or Office initially housed in the Department of Commerce) — charged with long‑term transmission planning, development services, siting/permitting coordination, and collaboration with utilities, tribes, local governments, regional and federal entities.
- Duties include: supporting new interstate and intrastate transmission projects; promoting grid‑enhancing technologies, reconductoring, and non‑wires alternatives; assisting community microgrids and distributed energy resources; and evaluating regional wholesale market participation.
- Governance and staffing: a governor‑appointed board (7–10 members in different drafts) plus an executive director (appointment requires board affirmative votes) and staff to implement the authority’s duties.
- Planning and reporting: requires a statewide transmission needs assessment (to be updated by October 30, 2031 and at least every five years thereafter) and periodic activity and financial reports to the Governor and Legislature (deadlines vary by amendment—initial reports due Dec 1, 2025; then annually).
- Regulatory relationships: many drafts state the authority and facilities it acquires are not subject to Washington Utilities and Transportation Commission (WUTC) jurisdiction, though utilities cannot recover costs in rate base absent WUTC approval.
Notable, contested provisions and amendments
- SEPA categorical exemption: some versions provide a categorical SEPA exemption for certain upgrades/rebuilds of existing transmission lines (115 kV+); other amendments would remove that exemption.
- Eminent domain: proposals differ — one amendment would prohibit the authority from using eminent domain until a wildfire claims fund holds $200 million; another would eliminate the authority’s eminent domain power entirely.
- Local permitting: some drafts require counties to adopt specific permitting processes and make grants available to cover adoption costs; other amendments remove those requirements.
- Incentive ratemaking: certain versions permit an incentive rate of return for investor‑owned utilities on new transmission upgrades (e.g., 15 years), subject to WUTC authorization.
Who would be affected
- Electric utilities (investor‑owned and consumer‑owned), transmission developers, regional entities (including BPA), local and tribal governments, labor (electric workers), landowners and rights‑of‑way holders, ratepayers, and overburdened communities. Environmental, cultural resource protection, and wildfire mitigation are explicitly included in the authority’s duties.
Potential impacts and policy considerations
- Intended to accelerate transmission delivery needed for clean energy buildout and reliability, but raises tradeoffs around local permitting, environmental review (SEPA), eminent domain, and the degree of regulatory oversight (WUTC). Implementation timing, funding, and governance details remain focal points in amendments and committee debate.
