Rotating Outages and Emergencies

System Status: Normal

When the state's power reserves are at critically low levels, CAISO rotating outages are possible. Please read these FAQs to prepare for potential power outages. CAISO rotating outages typically last one hour. You may also look at CAISO's online system status report.

CAISO Rotating Outages

Visit the Rotating Outage status page to find out if your power is out due to a CAISO rotating outage. You can also view the next set of groups that would be called in a CAISO rotating outage.  

What is a CAISO Rotating Outage?

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.

For more than 15 years we have maintained a 99.98% Service Reliability rating for our customers (Check the CPUC's Electric Service Reliability Annual Reports). Predicting electricity demands and generation availability is at best an approximation. The Cal-ISO's forecasts and system status change quickly, causing our real-time electric grid management plan to change also. We make every effort to keep information posted on this Web site accurate.
