ROSEMEAD, Calif., April 16, 2015 — Southern California Edison (SCE) supports Tuesday’s announcement that the California Independent System Operator (CAISO) and PacifiCorp are mutually interested in evaluating the feasibility of including the two PacifiCorp service territories as full participants in the CAISO. 

Over the next several months, the CAISO and PacifiCorp will conduct an analysis of the cost and benefits associated with full participation. The process will include ample opportunities for stakeholder comments, and the CAISO board of governors' approval is required to take any further steps toward full integration.

“Southern California Edison is highly interested in this possible geographic expansion and looks forward to definitive analysis of the reliability and environmental benefits to our customers of this potential expansion,” said Ron Nichols, senior vice president of Regulatory Affairs for SCE.

Increasing the geographic area and diversity of customer electricity usage through an expanded CAISO area could increase the ability to integrate renewable energy resources onto the grid and benefit California consumers.
