This bill amends Washington’s Clean Energy Transformation Act provisions (including RCW 19.405.040 and stated amendments to RCW 19.405.020 and 19.405.100) to require that all retail electricity sales in the state be greenhouse gas neutral by January 1, 2030 and to establish four multiyear compliance periods from 2029–2044. Utilities must pursue all cost‑effective conservation and efficiency and must use nonemitting generation and renewable resources equal to 100% of their retail electric loads in each compliance period, with up to 20% of a utility’s obligation through December 31, 2044 allowed to be met by specified alternative compliance options. Those options include an alternative compliance payment, use of unbundled renewable energy credits (RECs) under no‑double‑counting rules, investments in energy transformation projects, investment in advanced nuclear reactor projects, and electricity from certain municipal solid waste energy recovery facilities that a life‑cycle analysis shows reduce net greenhouse gases. The bill also limits use of hydroelectric resources constructed after May 7, 2019, requires REC retirement in a tracking system selected by the department, and requires that nonemitting generation used for compliance be generated during the compliance period with the utility owning the nonpower attributes. The bill makes procedural and rulemaking changes: it directs the Washington utilities and transportation commission to adopt rules for investor‑owned utilities and the Department of Commerce (referred to in the text as “the department”) to adopt rules for consumer‑owned utilities, reporting requirements, thermal REC measurement and tracking, and verification procedures for advanced nuclear reactor projects and energy transformation investments. The Department of Ecology must adopt criteria and conversion factors to convert emissions reductions from energy transformation projects to megawatt‑hours, and rules are required for verifying that projects meet statutory requirements. The measure also creates an early action compliance credit allowing a utility to count electricity allocations before December 31, 2025 toward compliance if the utility demonstrates a real, permanent greenhouse gas reduction in the western interconnection; multistate utilities must request use of these credits in their implementation plans and may not use them beyond 2035. Utilities that fail to meet requirements are subject to the administrative penalty in RCW 19.405.090(1). Several statutory definitions are added or clarified in the bill text provided, including definitions for “advanced nuclear reactor,” “energy transformation project,” “nonemitting electric generation,” “renewable resource,” “renewable energy credit,” “market customer,” and others. Important implementation details and some statutory text are missing from the extracted material: the full amended texts of RCW 19.405.020 and 19.405.100 and a new section referenced in the bill are not included here; some definitions (for example the full definition of “nonpower attributes”) are truncated; and portions of subsection text continue beyond the provided excerpts, so specific eligibility rules and other operational details for advanced nuclear projects, the REC tracking system, and conversion protocols are not fully shown.

If enacted, utilities would have to make their Washington retail electricity sales greenhouse gas neutral by January 1, 2030 and show 100% renewable or nonemitting generation over four-year compliance periods through 2044, while being allowed to meet up to 20% of that obligation through specified alternative compliance options (unbundled RECs under tracking rules, energy transformation projects judged by the Department of Ecology, certain pre-1992 municipal solid waste facilities, investments in advanced nuclear reactor projects, or an alternative compliance payment). In practice this will push utilities to increase investments in conservation, renewables, energy storage, and other nonemitting sources, consider partnering on or funding advanced nuclear and energy transformation projects to meet part of their obligation, and avoid new large hydro diversions or expansions after May 7, 2019; utilities that miss requirements face administrative penalties. The parties most affected are investor-owned and consumer-owned electric utilities (including multistate utilities), BPA and its preference customers, and any utilities participating in joint projects; they will likely incur new costs for generation and project investments, reporting and verification, and for meeting equity and community-benefit obligations, but gain limited flexibility to use alternative compliance measures and early action credits for allocations before December 31, 2025 (early credits must show real, permanent GHG reductions in the western interconnection and cannot be used after 2035). Key implementation details—such as the department and commission rulemaking, the Department of Ecology’s conversion factors and verification protocols for energy transformation and advanced nuclear projects, and the REC tracking system—are not fully specified here, creating uncertainty that could affect planning, timing, and cost estimates.
