How will I know if my power will go out?

If rotating outages are needed, PG&E will post information at this page to show the order in which PG&E will likely proceed, if ordered by CAISO to turn off power. Estimated restoration times are 2-3 hours after the outage actually starts. The situation remains dynamic and shutoff times may change. Check back at this page frequently for updates.

How rotating outages are different from a Public Safety Power Shutoff (PSPS)

Public Safety Power Safety (PSPS) events are called during specific high fire-threat conditions. Rotating outages are due to strain on California's grid. The need for outages is determined by the statewide grid operator and not PG&E. Rotating outages are not related to any issues with PG&E's equipment or its ability to deliver energy locally.

PG&E does not anticipate initiating any Public Safety Power Shutoff events this week. Any power outages that occur during this hot spell are not PSPS events. To learn more about PSPS events, visit

What is a CAISO rotating outage?

Rotating outages (Stage 3 Emergencies) become necessary when the ISO is unable to meet minimum contingency reserve requirements and load interruption is imminent or in progress. These emergencies are declared by the California Independent System Operator (CAISO).

The CAISO oversees the larger power grid and balances energy demand with supply. As the electricity balancing authority, the CAISO is responsible for evaluating forecasting models for both customer demand and generation supply.

CAISO will typically order the state's utilities, including PG&E, to reduce electrical load by turning off service immediately in order to prevent larger outages on the grid. Due to the emergency nature of these outages, we will not be able to give advance warning to customers.

Should the CAISO declare a Stage 3 emergency that requires the use of rotating outages, PG&E will first reduce load to specific groups of customers. Then, if additional reduction in load is needed, PG&E will turn off power to groups of customers according to their rotating outage block number.

These are called rotating block outages. These outages help alleviate grid capacity and power generation issues by rotating sets of customers through a temporary outage during different times until the rotating outages are no longer needed.
