URGENT PG & E: Record breaking heatwave strains the grid causing rolling blackouts through Thursday

By ONME Newswire

PG&E: "...These are not related to any issues with PG&E's equipment or its ability to deliver energy locally. "


Due to extreme heat across all of California, the California Independent System Operator (CAISO) that runs the state's electric grid, may require PG&E and other electric utilities to turn off power for short periods of time called rotating outages.


These outages may 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. Other power utilities in the state may be directed to conduct similar rotating outages. These outages are called by CAISO to keep energy demand from exceeding supply, and prevent larger outages on 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. All utilities in the state – including PG&E have been called on to participate.

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.

Based on the weather forecast, these potential rotating outages could occur during peak periods of approximately 3 pm to 10 pm each day, starting Monday, August 17th and continuing through the evening of Thursday, August 20th. A decision on whether to do them will be made by CAISO each day. PG&E strongly encourages customers to conserve energy and cooling homes in the morning hours through Thursday night. These outages could happen statewide and not just in PG&E's service area.



What residents are asked to do


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.


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). 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.
