2025 Washington Situs Request for Proposals

Background

The 2025 Integrated Resource Plan (IRP) established an action item to initiate request for proposals (RFP) to procure resources for its Washington customers that are aligned with the 2025 IRP preferred portfolio and that can achieve commercial operation by the end of December 2029. The 2025 IRP estimates a need for as much as 900 megawatts of generation resources primarily to satisfy Washington Clean Energy Transformation Act (CETA) compliance and 1,385 megawatts of storage to primarily satisfy Western Resource Adequacy Program (WRAP) compliance for capacity. 

PacifiCorp’s 2025 Washington Situs RFP is seeking competitively priced resources that are agnostic to both duration and technology type. PacifiCorp’s 2025 Washington Situs Request for Proposals will consider power purchase agreement and energy storage agreement bids. PacifiCorp is not submitting any self-build (benchmark) resources in its 2025 Washington Situs Request for Proposals.
