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, known as rotating outage groups or rotating outage group blocks, to help ease the demand on the electrical grid. These rotating outages help your community avoid larger and longer lasting power outages.

Please check our FAQ's for more information about rotating outages.

If you provide public health, safety, or security services, you may qualify for exemption from rotating outages. Learn more >
