Our response to COVID-19
We’ve made some changes due to COVID-19, including suspending service disconnections for residential and small business customers for nonpayment, and only continuing critical work needed to protect public safety and reduce the risk of wildfires. Learn more here. If you have recently lost your job, even if you are receiving unemployment benefits, you may qualify for a reduced energy rate through our CARE or FERA programs. Learn more.

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.
