Heat waves may strain the grid

During heat waves, the California Independent System Operator (CAISO), the organization that runs the state’s electric grid, can call for rotating outages statewide to protect the stability of the grid. Most utilities in the state including PG&E could be called on to participate.

These outages should last between 1 to 2 hours for most customers. These are not Public Safety Power Shutoffs due to extreme fire danger and are not related to any issues with PG&E’s equipment or its ability to deliver energy locally.

You can do your part to help prevent blackouts by conserving energy. Set thermostats to 78 degrees or higher. Run energy intensive appliances during early morning or after 9 p.m. Close drapes and blinds to keep rooms cool.
