What is a rotating outage?
When the California ISO, the agency that manages the power grid, notifies utilities to quickly reduce electricity deliveries to their customers, it calls for rotating outages. The utilities must shut off electricity to select groups, or blocks, of customers on a controlled basis to prevent large-scale power outages across the state. These customers will generally be without electricity for 1 hour or less. At the end of the hour, power is restored. A rotating outage can result from shortages in generating capacity or the inability to deliver power to regions of the state due to problems or interruptions in delivery of electric over portions of the state-wide electric transmission grid. There may be advance notice of a rotating outage or there may be no advance notice at all, depending upon the circumstances causing the need for the outage.
