SDG&E Notifies Customers of Potential Rotating Outages at Request of State Grid Operator

Update as of July 9, 2021, 9:00 p.m.:

Rotating outages were averted tonight, in part thanks to consumer conservation. Today’s Flex Alert – call for voluntary conservation issued by the California Independent System Operator (CAISO) – ended at 9 p.m. tonight.

CAISO, however, has extended the Flex Alert to tomorrow, July 10, from 4 p.m. – 9 p.m.

Thank you for your cooperation!


Due to excessive heat and a wildfire in southern Oregon impacting energy imports into the state, the California Independent System Operator (CAISO) has notified utilities across the state that they may have to implement rotating outages to help maintain grid stability, in the event conditions worsen.

Per CAISO’s order, SDG&E has notified 55,905 customers that they could be without power for approximately 60 minutes.

Residents and businesses across California are urged to help conserve energy. Last year, consumer conservation was credited with reducing or averting some of the rotating outages.

Earlier in the day, CAISO declared a Flex Alert – a voluntary call for energy conservation – for today, July 9, and tomorrow, July 10, from 4 p.m. – 10 p.m. due to excessive heat across the state.

Information on potentially impacted circuits may be found at https://www.sdge.com/rotatingoutage

Customers may find their circuit number on their electric bill under the “Detail of Current Charges” section. 

SDG&E will provide more information through local news outlets, our social media channels and sdge.com if rotating outages are required.
