CAISO rotating outages (Stage 3 CAISO Emergencies) become necessary when the state's electricity demand outpaces available supply in real time or are unavoidable. CAISO will typically order the state's investor-owned utilities, including SCE, to reduce electrical load by turning off service immediately.

A rotating outage typically lasts one hour. We manage and rotate the outage across groups of customers throughout the service territory to protect the integrity of our electric system, while limiting the inconvenience to any one customer or community.
