Why does the power go out?
Unexpected outages

Our crews work around the clock to restore service following a variety of unexpected outage causes:

  • Weather - Lighting, wind, rain, snow, ice, excessive heat/cold that may have impacted our electrical equipment
  • Equipment - Wear and tear. Many things fall under this category, could include overhead electrical equipment, underground electrical equipment, and transmission equipment. This could include small connections at the customer's residence to transmission lines that serve thousands of customers.
  • Miscellaneous - Mechanical damage, construction error, fire, etc.
  • Animal - Contact with electrical equipment
  • Trees - Fallen trees, branches, tree growth into equipment
  • Human - Accidents, vandalism or other human caused outages

Scheduled outages

You may receive a notice or a phone call about a scheduled outage that will interrupt your service. It means crews will be performing maintenance or upgrading equipment that serves you or your neighborhood.

We'll let you know a day in advance and try to be as accurate as possible, but the outage may not begin or end at the exact time. Occasionally, weather and operational issues may cancel a scheduled outage.

Part of your notice is a code that indicates the general type of work we'll be doing:

Code Work
A General maintenance that could include replacing transformers
WPM Testing, repairing or replacing aged power poles
VM Surveying or trimming vegetation near power lines
SG Upgrading equipment to include modern technology
GR Replacing natural gas pipeline
FR Upgrading power poles, lines and other equipment on a specific branch of our distribution system
UR Performing annual survey of natural gas lines

If you're part of a scheduled outage, here are a few steps you can take to be prepared:

  • Make sure food stays as cold as possible by keeping refrigerator and freezer doors closed. Block ice can be used.
  • Learn how to manually open security gates and garage doors.
  • Notify any security companies that monitor your home or business.
  • Protect computers, televisions and other sensitive equipment by unplugging them.

If your power goes out and you have not been notified in advance, make sure to let us know. You can also report an outage on a mobile device at avistautilities.com or by calling us at (800) 227-9187. You can also track outages online.
