Integrated Resource Plan

Integrated Resource Plan

Mossyrock – One of Seven of Our Dams

The Integrated Resource Plan (IRP) is a tool to help Tacoma Power plan for an uncertain future so we can continue to meet our customers’ needs for decades to come. Approximately every four years, we complete a full refresh of the IRP. We also revisit and make small updates to the plan between the larger refresh years. We completed a full refresh of the IRP in 2020 and will complete an update in 2022.

Clean Energy Implementation Plan

In 2019, Governor Jay Inslee signed into law the Clean Energy Transformation Act (CETA), which commits the State of Washington to an electricity supply free of greenhouse gas emissions by 2045. The landmark law imposes new clean energy mandates on electric utilities in Washington as well as planning and reporting requirements. One of those new requirements is that utilities complete a Clean Energy Implementation Plan (CEIP) by January 1, 2022 and every four years thereafter. Our draft 2022 CEIP is available for you to review now. We will seek Public Utility Board approval of the plan in December 2021.
