BACKGROUND

Orange County Sanitation District (OC San) operates five Central Generation (CenGen) engines and a steam turbine at Plant No. 2. The engines and steam turbine normally generate 100% of the power demand at Plant No. 2 and a nominal amount that is exported.

OC San and Southern California Edison (SCE) entered into a Power Purchase Agreement (PPA) on September 9, 1991. OC San has applied for the Wholesale Distribution Access Tariff (WDAT) with SCE which will allow OC San to sell exported power to an eligible purchaser. A condition of the WDAT application is to have a Generator Interconnection Agreement (GIA) in place with SCE.

RELEVANT STANDARDS

PROBLEM

OC San's WDAT application is dependent on the execution of a GIA with SCE. If the GIA is not approved by October 31, 2025, SCE will deem OC San's WDAT application withdrawn.

PROPOSED SOLUTION

Approve the GIA with SCE to continue processing OC San's WDAT application for the ability to sell exported power.
