Currently, the methodology is complex and includes calculating the difference between the actual costs paid by SDG&E and the current market value of those energy resources, or above market costs. In addition to conventional power, the PCIA includes benchmarks for resource adequacy, renewable energy, and other energy attributes that impact the value of the utility’s energy portfolio. The calculation methodology is intended to ensure that both utility and CCA customers pay their fair share for energy resources that the utility procured on their behalf.
