Substantial winds across Idaho and Washington that began the afternoon of Nov. 15, and that continue tonight, have caused power outages across Avista’s service area, primarily due to heavy wind causing branches and trees to come into contact with powerlines.

Outages began to occur on Avista’s system just after 3 p.m., and winds are expected to continue through 10 p.m. As the wind subsides and as it is safe to do so, Avista is focused on assessing the extent of the damage to the electric system and restoring power. Given this ongoing assessment, estimated restoration times are currently unknown and may take 24 hours or more in some cases.

Avista crews are working tonight and will continue to work around the clock as quickly and safely as possible until all customers are restored.

While estimated restoration times are unknown, customers should be prepared for prolonged outages and seek resources as needed. Once crews have been able to assess each area, we will provide updated restoration times for our customers.

Due to these outages, Avista is experiencing higher than normal call volumes, and we appreciate our customers’ patience.

What customers can do

Customers should report their outage at, through the outage app or by calling (800) 227-9187.

Safety during an outage

We want our customers to stay safe. Customers should treat all power lines as if they are energized. Customers should stay away from any downed or hanging power lines, not attempt to remove limbs from downed or sagging power lines, and should not drive over power lines. If customers see a downed power line, they should call Avista at (800) 227-9187 immediately to report its location or email

Avista suggests customers take the following steps during an outage:

Turn off all the appliances that were on before the power went out.

Unplug electronic equipment, including computers.

Leave a light or radio on as an alert when power has been restored.

Help Avista crews working in a neighborhood know which homes have power by turning on the front porch light.

Do not wire an emergency generator into a home’s electrical system, unless there is a disconnect switch to separate generated power from Avista’s distribution system. Backfeed into power lines could injure or kill a lineman working to get electricity restored.

Use a generator only to run specific appliances and locate it outside so poisonous carbon monoxide fumes do not enter the home.
