CPUC Approves Peak Period Shifts for SDG&E TOU Rates

The California Public Utilities Commission (CPUC) has approved peak period shifts for San Diego Gas & Electric (SDG&E), which officially went into effect on December 1, 2017. The changes include a major shift of the time-of-use (TOU) periods, moving the midday summer “on-peak” window from 11am to 6pm, out to 4pm – 9pm. SDG&E becomes the first investor owned utility (IOU) in California to implement these radical changes, as part of their General Rate Case (GRC) filing. Both Pacific Gas & Electric (PG&E), and Southern California Edison (SCE) are looking to follow suit in their pending GRC filings.
