Phase 3 Integrated Resource Planning Reliability RFO 2025-2031

San Diego Gas & Electric Company (“SDG&E”) seeks through this Phase 3 Integrated Resource Planning (“IRP”) Reliability Request for Offers (“RFO”) to procure resources to meet electric system reliability needs as required by California Public Utilities Commission ("CPUC") Decision (“D.”)21-06-035, D.23-02-040 and D.24-02-047 (together, the “Decisions”).

The Decisions require SDG&E to solicit offers from owners and operators for the purchase of eligible system-level resource adequacy (“RA”). Through this RFO, SDG&E is seeking eligible system-level resource adequacy to come online by and between June 1, 2025 and June 1, 2028, as described in more detail below; provided that, SDG&E will consider offers for Long-Lead Time (“LLT”) resources that may come online by June 1, 2031 pursuant to the requirements set forth in D.24-02-047.

Additionally, as a result of the D. 23-06-029 Summer Reliability procurement mandate, SDG&E seeks to meet an electric system reliability target of 170-320 MW, which includes an effective planning reserve margin, to come online by June 1, 2025. SDG&E will also consider firm energy imports that can be delivered starting June 1, 2024

To meet the requirements, SDG&E seeks to execute agreements for:

• Projects that qualify as zero-emitting or generic, non-fossil fueled resources that intend to meet the June 1, 2025, and June 1, 2027, online date and shall have the following characteristics:
  • Be from a standalone RPS generation resource, standalone storage, a generation resource paired with storage (physically or contractually), or a demand response resource;
  • Be available every day from 5 p.m. to 10 p.m. (the beginning of hour ending 1800 through the end of hour ending 2200), Pacific Time, at a minimum; and
  • For Diablo Canyon Power Plant (“DCPP”) replacement capacity to be online by June 1, 2025, be able to deliver at least 5 megawatt-hours of energy during each of these daily periods for every megawatt of incremental capacity claimed, or
  • Otherwise be able to meet all applicable rules to count for RA.
• Projects that qualify as LLT resources that intend to come online on or before June 1, 2028, are divided equally between the following product categories and shall have the following characteristics:
  • 50% of long-duration storage (able to deliver at maximum capacity for at least eight hours from a single resource); and 
  • 50% of generation capacity that has no on-site emissions or is eligible under the requirements of the renewables portfolio standard program and has at least an 80 percent capacity factor. The resource must not be use limited or weather dependent. No storage projects shall qualify under this provision.
• Firm energy imports that follow the eligibility and counting rules of the resource adequacy program in place at the time of contract execution and must be associated with a new resource or an increase of capacity from an existing resource with a delivery start date after June 30, 2021. Firm energy imports may count for any requirement of this procurement, including Summer Reliability, generic capacity and LLT resources, depending on the project that the firm energy import is sourced from. SDG&E will also consider firm energy imports that can be delivered starting June 1, 2024.
