Information On Rotating Outages and Emergencies

What is a Rotating Outage?

A rotating outage is a controlled electric outage that is called as a last resort when there is a regional power emergency. For an hour at a time, we shut down power by geographical groups on our system to help ease the demand on the electrical grid. Rotating outages help your community avoid larger and longer lasting power outages.

Where do I find my Rotating Outage Group Number?

You can find your Rotating Outage Group in a number of ways:

  • Your Rotating Outage Group is located on the front of your SCE bill. Summary Bill customers will find this information in the "Details" portion of their bill.
  • You can also find your current Rotating Outage Group Number online by registering for My Account. Once enrolled in My Account, you will have easy access to all of your accounts in one place making looking up multiple rotating outage group numbers a snap.
  • In the event of a stage 3 emergency, you can call us at 1-800-611-1911 and use the voice response system to get your current rotating outage group number.
  • You can also look up Rotating Outage Maps in your area.

Rotating Outage Groups will fall into the following categories:

  • A, M, R, S, X - These groups are subject to rotating outages.
  • N, EXEMPT - These groups are not subject to rotating outages.

Please check out FAQ's for more information.

Please note that due to the uncertainties of electric system operating conditions during emergencies, we cannot predict or forecast exactly when an outage group may be affected by a rotating outage. The Rotating Outage Group shown on your bill may change at any time, without notice, due to electric system operating needs.

Select any of the rotating outage group numbers below to see:

  • A list of the communities and neighborhoods included in that group.
  • Maps showing the affected areas within those communities.

Note: There are no community listings or maps for outage groups beginning with the letter "S".


Essential Use Customers

Critical public services like fire stations and hospitals are considered essential use customers. Essential use customers are exempt from rotating outages.

Some essential facilities with a backup generator may not be exempt from rotating outages. This allows greater support to essential facilities that do not have a generator as a source of backup power. Hospitals and licensed nursing facilities are always exempt from rotating electric outages.

Please Note: We review and update our Essential Use customer list annually. If the status of your facility changes, you will receive a 15-day advance notice from us.

What happens if my power is out and I'm an Essential Use Customer?

On rare occasions, an Essential Use customer may experience a rotating outage. In these unusual cases, business customers please call 1-800-990-7788. We will take all possible measures to quickly restore power.

How can I stay cool during a rotating outage?

Cooling stations are facilities you can visit to stay cool during a rotating outage. These facilities are made available by community businesses and organizations. They are open to the public, but have limited space. We are in the process of updating our list of locations, please check back later.

If you have a medical condition affected by extreme temperatures, you may be eligible to apply for additional alert status.
