The Idaho Public Utilities Commission has opened a window for public comment regarding three separate rate applications submitted by Avista Utilities. The filings concern natural gas service for customers across North Idaho, including residents in Sandpoint, Priest River, and Clark Fork. Each application addresses a different aspect of utility billing structure, cost recovery, and program funding.
Billing Structure Adjustments
The first application, designated AVU-G-26-02, requests approval for a Fixed Cost Adjustment (FCA). This mechanism is designed to decouple the utility’s revenue from the volume of energy consumed by customers. Under traditional billing models, utilities earn more when customers use more gas. The FCA removes that incentive, ensuring Avista can recover fixed operational costs regardless of fluctuating usage levels due to weather or conservation efforts.
The second filing, AVU-G-26-03, addresses the Purchased Gas Adjustment (PGA). This rate component allows Avista to adjust charges in line with the actual market costs of purchasing natural gas, including expenses associated with transportation and storage. The PGA ensures that customers pay for the commodity cost as it occurs, rather than having those costs averaged over longer periods.
Energy Efficiency Program Changes
The third application, AVU-G-26-05, proposes significant changes to the natural gas energy efficiency rider. Currently, this charge funds Avista’s conservation programs, which include rebates for Energy Star-certified windows and customer education initiatives aimed at reducing overall consumption.
Avista is seeking a temporary suspension of these energy efficiency programs. The utility proposes reducing the energy efficiency charge to $0.00000 per therm. This move effectively halts the collection of funds designated for rebate and educational programs, shifting the financial burden away from ratepayers in the short term.
If approved as filed, the combined effect of these changes would result in a slight decrease in monthly bills for residential customers. For a typical household using 66 therms per month, the average bill would drop from $59.28 to $58.38. This represents a reduction of approximately 1.5 percent. While modest, the change reflects a shift in how fixed costs and program funding are distributed across the customer base.
Public Comment Deadlines
The Idaho PUC is accepting written comments on each application separately, with deadlines set for mid-October 2026. Residents, businesses, and advocacy groups interested in providing input must submit their remarks by the specified dates.
Comments on the Fixed Cost Adjustment case (AVU-G-26-02) are due by October 13, 2026. The Purchased Gas Adjustment case (AVU-G-26-03) and the Energy Efficiency Rider case (AVU-G-26-05) both have a deadline of October 14, 2026.
The commission’s process allows stakeholders to weigh in on whether these billing adjustments serve the public interest. The FCA model is often supported by utilities as a way to stabilize revenue streams without penalizing customers who conserve energy. Critics sometimes argue that decoupling removes market incentives for efficiency, though Avista’s proposal simultaneously reduces charges tied to conservation programs.
For Idaho ratepayers, the outcome of these cases could set precedents for how utility costs are structured in the coming years. The PGA mechanism ensures transparency in commodity pricing, while the FCA addresses the challenge of recovering fixed infrastructure costs in an era of increasing energy efficiency.
What Comes Next
The Idaho Public Utilities Commission will review all submitted comments before making a determination on each application. Hearings may be scheduled following the comment period, depending on the volume and nature of public input. Decisions are expected to impact billing cycles starting in late 2026 or early 2027.
Stakeholders should monitor official PUC filings for updates on case status. The commission’s website provides access to full applications, supporting documents, and final orders once issued.
