AI overview
San Diego Gas & Electric Company (SDG&E) has issued a Request for Information (RFI) to solicit interest from third parties with projects in the California Independent System Operator (CAISO) Cluster 16 interconnection queue. The purpose of this RFI is to identify projects that may be awarded a Commercial Interest Point Allocation (CIPA) from SDG&E. Respondents must meet minimum eligibility criteria including at least 90% site control as required by FERC Order No. 2023, Transmission Plan Deliverability (TPD) available at the project's Point of Interconnection (POI) and within the CAISO interconnection zone (not required for Energy Only projects), and submission of a completed SDG&E RFI Offer Form. SDG&E encourages respondents to submit additional information for full evaluation and reserves the right to allocate commercial interest points at its sole discretion consistent with applicable laws and regulations.
Key dates for this RFI include a Q&A deadline of July 17, 2026, and project information submissions due from respondents by July 31, 2026, at 5:00 PM Pacific Prevailing Time. Following submission, SDG&E will issue a shortlist notification on August 28, 2026. Successful respondents may be required to execute an exclusivity agreement and post collateral by September 25, 2026, or alternatively elect to opt out of an exclusivity arrangement. The final Commercial Interest Point Allocation must be submitted to the CAISO by October 29, 2026. All deadlines occur at 5:00 PM PPT, and SDG&E may revise the schedule at its discretion.
Submission materials must be uploaded through the PowerAdvocate platform, where the RFI protocol document and all related forms are available. Required documentation includes site control evidence, TPD deliverability evidence, the completed RFI Offer Form, and either a signed exclusivity agreement or an opt-out election. Respondents without a PowerAdvocate account must register to access the event. All questions and communications regarding this RFI must be directed to RFI@sdge.com with a copy to the independent evaluator, Keith Oliver at keith.oliver@merrimackenergy.com.
This RFI is part of SDG&E's process to allocate its commercial interest points for projects entering the CAISO Cluster 16 interconnection queue. The allocated points support generation projects—including renewable and conventional resources—seeking interconnection to the grid. The RFI does not include a specified budget or contract value; the allocation itself is the primary deliverable. Respondents are encouraged to monitor the RFI website for updates, notices, and any amendments to the process.
