2024 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, DER and DSS RFPs, PSE will be issuing a voluntary Distributed Solar and Storage (“DSS”) RFP in 2024 to solicit distributed solar and storage resources.
In early 2022, PSE selected a vendor for its virtual power plant (“VPP”) platform that will be used to dispatch DERs. PSE is currently working on developing and testing the VPP platform, which will manage all applicable DERs in the future. Further details on VPP integration are provided in the RFP. 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@veosonica.com.
The following estimated schedule is subject to adjustment based on the actual pace of the evaluation process. More information on the DSS RFP process and timeline will be provided throughout the process.
To submit a bid for the 2024 DSS RFP, qualified respondents must create and register an account at PSE’s RFP submission portal.
