The latest power outage updates

Avista crews, along with contractors and mutual aid crews from six western states and British Columbia, are working 16-hour shifts to restore power to the remaining 18,000 customers who are without power since the devastating November 17 wind storm.

Avista says the majority of customers should have power by midnight Wednesday, but based on the extent of the damage in certain areas, as many as 5,000 customers may not have power for Thanksgiving. Those hardest hit areas should have power restored by Friday.

As of Tuesday afternoon, 90 percent of the 180,000 customers who lost power last Tuesday have had their power restored.

"We are keenly aware of the hardship, stress and frustration people are experiencing, particularly with today’s weather and the holiday approaching,” said Avista CEO Scott Morris. “Our crews and support staff will be working through the Thanksgiving holiday, and we will do what it takes to restore power to every last customer.”

As of Tuesday there are more than 100 crews, about 700 workers, that continue working around the clock, which is about five times Avista's typical workforce for the company's entire service area, and 10 times the typical Spokane workforce.
