Insights
Avista's Idaho rate adjustments balance revenue impacts across divisions, maintaining earnings neutrality despite customer bill changes.
Avista's latest regulatory filings with the Idaho Public Utilities Commission represent a common annual adjustment process that will not affect the company's earnings despite changing customer rates. The electric side shows a
These adjustments are primarily driven by several key mechanisms:
- The Power Cost Adjustment reflects lower power supply costs than currently built into rates, resulting in a
0.6% revenue decrease - The Fixed Cost Adjustment mechanisms for both electric and gas divisions help decouple revenues from consumption, addressing revenue shortfalls from conservation and weather variations
- The decrease in natural gas rates is significantly influenced by the Purchased Gas Cost Adjustment, reflecting lower wholesale natural gas prices during the past winter
From a regulatory perspective, these are routine filings that demonstrate Avista's effective use of established rate adjustment mechanisms. The residential customer impact is mixed – electric bills will increase by
While rate adjustments can sometimes create customer satisfaction challenges, the overall impact appears balanced, with the substantial natural gas decrease potentially offsetting concerns about the electric increase. These routine regulatory filings indicate normal business operations rather than any fundamental change to Avista's financial outlook or strategy.
Requests would result in higher electric prices effective Oct. 1, 2025 and lower natural gas prices effective Nov. 1, 2025.

Power Cost Adjustment (PCA)
The PCA is an annual rate adjustment made to reflect the difference between the actual cost of generating and purchasing electric power to serve customers and the cost currently included in customer rates. Over the last year, power supply costs were lower than those included in retail rates primarily due to lower wholesale electric and natural gas prices.
Fixed Cost Adjustment (FCA)
The electric and natural gas FCA is a mechanism designed to break the link between a utility’s revenues and customers’ energy usage. Avista’s actual revenue, based on kilowatt hour or therm sales, will vary, up or down, from the level included in a general rate case and approved by the Commission. This could be caused by changes in weather, energy conservation or other factors. Under the FCA, Avista’s revenues are adjusted each month based on the number of customers. The annual difference between revenues based on sales and the number of customers is surcharged or rebated to customers beginning in the following year. The proposed FCA rate adjustments are primarily driven by variations in customer usage related to weather and savings from participating in efficiency programs. The FCA mechanisms do not apply to Avista’s Electric Extra Large General and Street Lighting Service Schedules, nor to its Natural Gas Interruptible and Transportation Service Schedules.
Energy Efficiency Adjustment
The Energy Efficiency Adjustment is related to the funding of Avista’s electric energy efficiency programs. This adjustment aligns the amount that is collected in customer rates with the actual costs to operate the programs. Avista’s energy efficiency programs are designed to provide a financial incentive or rebate for cost-effective energy efficiency measures. The rate changes proposed reflect the required level of funding needed to operate the programs in the coming year.
Residential Exchange Adjustment
The Residential Exchange Program provides a share of the benefits of the federal Columbia River power system to the residential and small farm customers of the investor-owned utilities in the Pacific Northwest, including Avista. Avista applies the benefits it receives, which typically fluctuate from year to year, to customers as a credit in their monthly electric rates. The benefit Avista will receive from BPA starting in October 2025 will result in a lower level of benefits than is currently being passed through to qualifying customers.
Purchased Gas Cost Adjustment (PGA)
PGA requests are typically filed annually to balance the actual cost of wholesale natural gas purchased by Avista to serve customers with the amount presently included in customer’s rates. Avista does not make a profit on, or markup, the wholesale cost of natural gas. PGAs ensure customers pay what Avista pays, dollar for dollar, only at a more predictable and stable rate throughout the year. These rate adjustments are driven primarily by a reduction in the current surcharge amortization rate and lower wholesale natural gas prices observed during this past winter, which were below the amounts included in rates.
Rate Application Procedure
Avista’s applications are proposals, subject to public review and a Commission decision. Copies of the applications are available for public review at the offices of both the Commission and Avista, and on the Commission’s website (www.puc.idaho.gov).
