SoCalGas/SDG&E 2027 CAP: Embedded Cost Gains Ground as Intervenors Fracture

On June 15, parties served rebuttal testimony in SoCalGas/SDG&E's 2027 Cost Allocation Proceeding ("CAP," A.25-09-014). SoCalGas/SDG&E (the Sempra Utilities) and the following intervenors served rebuttal testimony:

• Clean Energy;
• Indicated Shippers;
• Southern California Generation Coalition (SCGC);
• TURN; and
• Western Manufactured Housing Communities Association (WMA).

On the biggest question in the proceeding, whether to retire Long-Run Marginal Cost (LRMC) and make embedded cost the universal allocation method, the applicants' submission is strong. The ultimate question is "who will pay," which has intervenors fractured.

Recall that the Sempra Utilities provided the following illustrative rates when they filed the CAP in September 2025.
