Integrated Resource Plan

The 2019 IRP Update was adopted by the Board of Commissioners on May 7, 2019. The 2019 Update includes a proposed long-term strategy that is similar to the 2017 IRP and ensures sufficient resources are available, at a reasonable cost, to meet the PUD’s changing energy and capacity needs for the 2020 through 2039 study period. The Update also includes a proposed action plan that outlines near term actions to begin implementing the resource strategy.

On a seasonal basis, the 2019 Update shows the PUD has a relatively small near-term winter capacity need in years 1-5. With accumulative conservation acquisition forecasted to reach 70 aMW through 2029, the utility's long-term capacity need that would serve both winter and future summer needs is deferred until the late 2020s. These results are similar to the 2017 IRP findings, but are smaller in scale due to the effects of conservation acquisition and codes and standards that have accrued and moderated load growth expectations.

The Draft 2021 IRP can be found on this page and is open for public feedback. The 2021 IRP considers a 2022-2045 study period and how the PUD will meet energy and capacity needs under the new Clean Energy Transformation Act policy in Washington state. The PUD has a carbon-free portfolio of power resources and proposes to add to its portfolio with conservation, demand response, local solar, and energy storage in order to meet customer needs at the lowest cost, while maintaining reliability and a commitment to clean energy. Interested customers can provide feedback on the plan to until December 7, 2021.
