Washington Electric Customers

During the review process for our electric and natural gas filings, the Washington Utilities and Transportation Commission (WUTC), will scrutinize every detail of our costs, review volumes of data and take public testimony.

Based on its investigation, the commission will then set rates it believes serve the public interest – rates that are reasonable and fair for customers, while allowing Avista the opportunity to be a viable, healthy business and earn a fair return for shareholders. That’s important so we can continue delivering safe, reliable energy.  The commission has up to 11 months to review and issue a decision on our request.

If approved by the WUTC, the requested increase:

  • is for an overall 13.4 percent increase,
  • would produce $55.3 million, or 13.4 percent, in additional billed revenue for electric service,
  • is based on a proposed rate of return on rate base of 8.33 percent, with a common equity ratio of 48.39 percent and a 10.9 percent return on equity, and
  • would increase the bill for a residential customer using an average 1,000 kilowatt hours a month by $10.62, or 14.8 percent, for a revised monthly bill of $82.41.

Addy-Gifford Line

Upgrading 2.5 miles of the Addy-Gifford transmission line in Stevens County, Wash., included replacing 37 wooden poles from the 1950s with new steel poles. The upgrade was necessary to ensure reliability in the mountainous, timbered terrain that experiences winter snow and summer wind storms. Additional upgrades are planned for the other sections of the 21-mile transmission line.

Crews work to remove wooden flashboards from our Nine Mile Falls hydroelectric project located on the Spokane River in Washington. The wooden flashboards are installed annually to extend the normal height of the dam for power generation when river levels are low. A mandate from our Spokane River Relicensing Project is to replace the wooden flashboards with an automated spillway.
