- First, we go to areas with downed equipment to make the area safe.
- Second, we repair damaged substations, which serve large numbers of customers.
- Next, we restore service to hospitals as well as public safety, water treatment and other critical facilities.
- Our next priority is repairing main distribution lines serving large areas and neighborhoods.
- As the other steps are completed, we begin working to fix outages in smaller areas and to individual homes and businesses.
Why power goes out
Power outages can occur for many reasons. Here’s a breakdown of the most common causes:
- 39% Equipment.
- 7% Weather, including lightning, wind, rain, heat, cold, snow and ice.
- 28% Fallen trees and limbs, and tree growth into power lines.
- 10% Animal contact.
- 8% Human accidents, vandalism, etc.

We sometimes interrupt service for maintenance work. We work to inform you and your community in advance of such outages.
Power outages of less than 5 minutes are considered momentary. Such outages are caused by wildlife, weather or trees making brief contact with our electric lines, or by contractor dig-ins into underground facilities.
