Subject of Possible Rule Making: In Commission Docket UE-210183, the commission has initiated this rule making to amend WAC 480-100-600 through 480-100-665 to implement chapter 19.405 RCW, with focus on sections RCW 19.405.030, [19.405.]040, [19.405.]050, [19.405.]130, and other portions of chapter 19.405 RCW that may affect or be affected by these subsections as enacted in E2SSB 5116, the Clean Energy Transformation Act (CETA).

Reasons Why Rules on this Subject may be Needed and What They Might Accomplish: RCW 19.405.130(3) requires the commission to adopt rules by June 30, 2022, defining the requirements for meeting the obligations under RCW 19.405.030 - [19.405.]050 with markets purchases from the Energy Imbalance Market and other centralized markets and to address the prohibition on double counting of nonpower attributes under RCW 19.405.040 that could occur under other programs. The rule making will also consider other issues related to chapter 19.405 RCW and the enactment of the CETA that were not fully addressed in the previous rule making, Dockets UE-190698 and UE-191023. Topics include the interpretation of RCW 19.405.040 (1)(a), the treatment of energy storage for compliance with RCW 19.405.030 through 19.405.050, and other portions of chapter 19.405 RCW that may affect or be affected by these portions of CETA.

Other Federal and State Agencies that Regulate this Subject and the Process Coordinating the Rule with These Agencies: The department of commerce is also required by RCW 19.405.130(3) to promulgate rules, and the two agencies will be working together to coordinate the respective rules.

Process for Developing New Rule: The utilities and transportation commission uses a collaborative rule-making process that includes stakeholder workshops, formal comments, and draft rules.
