Washington PBR Metrics
Washington Senate Bill 5295 (SB 5295) passed in the 2021 legislative session requires investor-owned utilities to file multi-year rate plans. As part of a proposed rate plan, a utility must also submit a set of Performance Based Ratemaking (PBR) metrics for the Commission to assess. The metrics may have penalties and incentives associated with them.
Avista filed its first proposed multi-year rate with the Washington Utilities & Transportation Commission (WUTC) following the enactment of SB 5295 in January 2022, in which it proposed a set of 12 metrics with penalties and incentives associated with the metrics. As part of a multi-party settlement reached in the rate case, Avista agreed to forego its set of proposed metrics and instead adopt a set of 92 metrics across 9 different categories (i.e., affordability, capital formation, equitable service, electric reliability, wildfire, customer experience, GHG emissions, electric grid benefits, and gas system benefits). Avista agreed that it will report out on the 92 metrics annually or quarterly for the duration of the 2-year rate plan, which was approved by the WUTC in December 2022.
For annual metrics, Avista will report calendar years 2022-2024, with data posted to its website within 45 days after the end of each year. For quarterly metrics, Avista agreed to begin reporting with the first quarter of 2023 and will report data within 45 days following the end of each quarter through Q4 2024.
