Integrated resource plan
The Integrated Resource Plan (IRP) is a forecast of conservation resources and supply-side resource additions that appear to be cost effective to meet the growing needs of our customers over the next 20 years.
We know these forecasts will change as the future unfolds and conditions change. Every two years, utilities are required to update integrated resource plans to reflect changing needs and available information. The last IRP was completed in 2017.
2019 IRP meeting schedule and materials
Between May 2018 and September 2019, ten formal 2019 IRP public participation meetings have been held and the meeting record is provided below. In December 2019, a webinar was held concerning the details of the social cost of carbon methodology and related results for scenarios comparing the social cost of carbon adder to a tax.
On October 28, 2019, the Washington Utilities and Transportation Commission Staff filed a Petition for Exemption from WAC 480-100-238 pursuant to WAC 480-07-100 until December 31, 2020. On November 7, 2019 the WUTC held an Open Meeting concerning this matter and subsequently issued Order 2, exempting PSE (and other investor owned utilities in Washington) from WAC 480-100-238.
Pursuant to Order 2, PSE filed an IRP Progress Report on November 15, 2019. On December 10, PSE filed a Revised Progress Report:
- 2019 Progress Report Revision cover letter dated December 10, 2019

Documentation of the public participation process for the 2019 IRP is included below. The IRP Advisory Group (IRPAG) and the Technical Advisory Group (TAG) were teams of external stakeholders and regulators who met to provide input during the integrated resource planning process.
The 2021 IRP will be filed with the Washington Utilities and Transportation Commission on or before April 1, 2021. This website will be refreshed when the 2021 IRP public participation process commences.
