What You'll Learn

Avista's rates are set by state utility commissions
The process of changing customer base rates involves a formal request from Avista to state utility commissions. This is called a general rate case, and it applies to Avista's customers in Idaho, Oregon, and Washington. The commissions then examine Avista's requests, take public comments, and set rates that are fair and reasonable for customers and Avista.
For example, in Washington, Avista filed a multi-year rate plan with the Washington Utilities and Transportation Commission (WUTC) in January 2024. If approved, the plan would allow Avista to recover increased operating and maintenance costs and ongoing investments in infrastructure and technology. As a result, residential electric customers in Washington could expect to see a total billed increase of 13.3%, or a revised monthly bill of $110.20, including a proposed $6.00 per month increase in the basic charge.
Avista also makes annual rate adjustments, such as the Power Cost Adjustment (PCA) in Idaho, which reflects the difference between the actual cost of generating and purchasing electric power and the cost currently included in customer rates. Additionally, Avista offers net metering, allowing customers with personal solar panels to sell their extra wattage back to the grid.
Overall, Avista's rates are designed to provide affordable, safe, and reliable energy to its customers, with the average monthly bundled electric bill being $106.22, significantly lower than the US average of $141.25 for bundled service.
