Power Cost Rate Adjustment and General Rate Request Filed in Washington

Avista has filed two requests with the Washington Utilities and Transportation Commission (UTC or Commission) to recover costs related to power supply as well as infrastructure, system maintenance, and technology. If approved, these requests would change the price our customers pay for the energy they use.

You expect your energy to be there when you need it, and to meet these expectations, we're continually investing in our systems to maintain reliability, and deliver value that leaves you satisfied, all at a reasonable cost.

We know you want rates that are fair and reasonable, and so do we. What does this request mean for you?

The specifics of why we've made these requests, what the requests could mean for your bill, and when the requests may take effect can be found in the links below.


We also have tools available to help you manage your monthly energy bill and usage. Visit our energy savings page for more about energy savings toolsenergy efficiency rebates and bill assistance.
