Rotating Outages and Emergencies

What is a Rotating Outage?

Sometimes called a “rolling blackout,” a Rotating Outage is an extremely rare, controlled power outage that we enact as a last resort when there is a statewide emergency. For one hour at a time, we shut down power by geographical groups – known as “Rotating Outage Groups” or “Rotating Outage Group Blocks” – to help ease the demand on the electrical grid. Rotating Outages help prevent larger and longer power outages.

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.
