2025 Distributed Solar and Storage RFP
Distributed energy resources (“DERs”) are a significant component of PSE’s preferred portfolio from PSE’s Integrated Resource Plan (“IRP”) and represent a piece of PSE’s strategy for achieving the targets laid out under the Clean Energy Transformation Act (“CETA”). In addition to its All-Source RFP, PSE will be issuing a voluntary Distributed Solar and Storage (“DSS”) RFP in late Q3 2025 to solicit distributed solar and storage resources.
In addition to the system-wide proposal solicitation, the 2025 DSS RFP will contain a targeted substation capacity solicitation. In this section, PSE is seeking proposals for energy storage projects interconnected to specific substations to contribute to local capacity needs. Details will be provided in the body of the RFP when it is issued.
Updates to the schedule and documents will be published below, as well as sent to stakeholders. To be added to the DSS RFP stakeholder distribution list, contact SolarStorageRFPmailbox@pse.com.
PSE will use an online submission portal to receive proposals. A link to the portal will be posted here after the RFP is issued.
