State of Washington
69th Legislature
2025 Regular Session
BySenate Environment, Energy & Technology (originally sponsored by Senators Shewmake, Slatter, Conway, Nobles, and SaldaƱa)
READ FIRST TIME 02/19/25.
AN ACT Relating to improving reliability and capacity of the electric transmission system in Washington state; reenacting and amending RCW 43.84.092 and 43.84.092; adding a new section to chapter 43.330 RCW; adding new sections to chapter 43.21C RCW; adding a new section to chapter 80.28 RCW; adding a new chapter to Title 43 RCW; creating a new section; providing an effective date; and providing an expiration date.
BE IT ENACTED BY THE LEGISLATURE OF THE STATE OF WASHINGTON:
NEW SECTION.  Sec. 1. (1) The legislature finds that Washington has committed to decarbonizing its electricity system so that it is carbon neutral by 2030 and carbon free by 2045. Achieving those goals includes retiring coal and gas resources, adding new generation from renewable and nonemitting resources, and leveraging energy storage technologies. At the same time, demand for electricity is increasing significantly due to the electrification of vehicles, home heating and cooling, and manufacturing, and the expansion of the information services sector in Washington. There are significant federal, state, and private investments in clean energy development, including wind, solar, and battery storage, that support decarbonization goals and supply new electrical load. However, Washington's existing transmission system lacks the capacity to accommodate the growing demand for clean electricity.
(2) The legislature also finds that extreme weather events and changes to seasonal highs and lows puts new strain on the existing transmission system and threatens reliability. Extreme weather events such as high-speed winds, floods, freezing, and heat domes can damage grid infrastructure and cause disruptions to the power supply. Warmer summers and colder winters increase the need for heating and cooling and thereby intensify and extend periods of peak demand.
(3) The legislature further finds that to maintain reliability and build resilience, Washington's transmission system needs to be expanded and upgraded to access diverse portfolios of clean and reliable energy across the region, including solar resources in the southwest and wind resources across the mountain west. A more robust and updated transmission system will support affordability and reliability goals by enabling the efficient dispatch of least-cost resources across the region.
(4) Therefore, it is the intent of the legislature to create the Washington electric transmission authority to improve transmission reliability, resilience, and affordability. The Washington electric transmission authority will serve as a centralized body to achieve these goals by engaging in long-term planning; providing development transmission services; coordinating siting and permitting; leveraging research; and engaging with utilities, transmission developers, local jurisdictions, state agencies, regional entities, the federal government, and affected communities. The legislature intends for the authority to achieve the following goals:
(a) Improve reliability and resilience, including during extreme weather events;
(b) Increase access to low-cost renewable energy;
(c) Achieve clean electricity requirements and greenhouse gas emissions limits;
(d) Support economic growth; and
(e) Maintain affordable energy rates.
PART I - WASHINGTON ELECTRIC TRANSMISSION AUTHORITY

Moneys in the account may be spent only after appropriation. Expenditures from the account may be used by the executive director of the authority, or the executive director's designee, to reimburse management costs incurred by the authority on electric transmission projects, for the acquisition of interests in land or other real property to be managed as electric transmission projects, and for all other nonoperating cost purposes consistent with this chapter.

(b) "Critical energy infrastructure information" means information regarding critical energy infrastructure where the information:
(i) Contains records of actual, potential, or threatened interference with, attacks on, compromise of, or incapacitation of critical energy infrastructure or protected systems by either physical or computer-based attacks, or other similar conduct that violates federal, state, or local law, harms interstate commerce of Washington state or the United States, or threatens to disrupt or diminish the supply of energy to the extent that the public health, safety, and general welfare may be jeopardized; or
(ii) Does not simply give the general location of or relay publicly available information about the critical energy infrastructure.
PART II - APPLICATION OF THE STATE ENVIRONMENTAL POLICY ACT TO TRANSMISSION IMPROVEMENTS
NEW SECTION.  Sec. 10. A new section is added to chapter 43.21C RCW to read as follows:
The following utility-related upgrading and rebuilding activities for existing electric transmission lines over 115 kilovolts, except on lands covered by water or underwater, are categorically exempt from compliance with this chapter:
(1) Rebuilding or upgrading within an existing right-of-way including reconductoring with advanced conductors and grid-enhancing technologies as defined in section 2 of this act;
(2) Relocating segments of transmission lines within an existing right-of-way or within adjacent previously disturbed or developed lands; and
(3) Widening an existing transmission line right-of-way to meet current electrical standards. The widening must be within previously disturbed or developed lands and only as needed to comply with applicable electrical standards.
NEW SECTION.  Sec. 11. A new section is added to chapter 43.21C RCW to read as follows:
(1) For a project that is categorically exempt under section 10 of this act, the authority must notify the department of archaeology and historic preservation created in chapter 43.334 RCW and each federally recognized Indian tribe with usual and accustomed areas and ceded treaty areas in the area where the right-of-way exists before commencing the project. The purpose of the notification and consultation required under this section is to allow the authority to determine that there are no existing archaeological, cultural, or tribal resources in the right-of-way. The department of archaeology and historic preservation may require a survey to be done in coordination with the affected federally recognized Indian tribe, must ensure that consultation with such tribes occurs, and must determine whether archaeological, cultural, or tribal resources are identified in an existing right-of-way. If any such resources are identified, the department of archaeology and historic preservation must ensure that the utility or transmission developer accounts for and protects the resources under chapter 27.53 RCW. Information provided by the federally recognized Indian tribe must be kept confidential and exempt from public disclosure under chapter 42.56 RCW.
(2) The definitions in section 2 of this act apply throughout this section unless the context clearly requires otherwise.
PART III - INCENTIVES FOR ELECTRIC TRANSMISSION INVESTMENT
NEW SECTION.  Sec. 12. A new section is added to chapter 80.28 RCW to read as follows:

The commission must consider and may adopt other policies to encourage increased deployment of electric transmission infrastructure improvements that increase the capacity of existing transmission infrastructure.
(2) An incentive rate of return on investment under this section may be allowed only if the company chooses to pursue capital investments in grid-enhancing technologies or reconductoring with advanced conductors. In the case of an incentive rate of return on investment allowed under this section, an increment of up to two percent may be added to the rate of return on common equity allowed on the company's other investments with demonstrated benefits to ratepayers.
(3) The incentive rate of return on investment authorized in subsection (2) of this section applies only to projects which have been installed after July 1, 2025.
(4) The incentive rate of return on investment increment pursuant to this section may be earned only for a period of 15 years. By December 31, 2029, the commission must report to the appropriate committees of the legislature on the use of any incentives allowed under this section, the quantifiable impacts of the incentives on electric transmission deployment, and any recommendations to the legislature about further utility investments in electric transmission.
