BOISE, ID – The Idaho Public Utilities Commission has set a March 12th intervenor deadline to participate in natural gas and electric rate cases filed by Avista Utilities. The company is seeking commission approval to increase its natural gas and electric service rates. Intervenors in a case can participate in the proceedings for applications submitted to the commission.
From the IPUC:
Avista is proposing to increase the electric rate for residential customers who use an average of 939 kilowatt hours per month by 14.7 percent. This represents an increase of $15.36 per month. Customers using an average of 939 kilowatt hours per month would see their bills increase from $104.30 to $119.66. The utility also is proposing to increase the basic charge to $25.00 per month, up from $20.00 per month. Avista is asking that the rate change begin on Sept. 1, 2025.
The utility also is seeking approval for a rate increase beginning Sept. 1, 2026. If approved, electric residential customers using an average of 939 kilowatt hours per month would see an increase of 5.3 percent, or $6.36, for a monthly bill of $126.02. This is an increase from $119.66 per month. The utility also is proposing an increase of $5 per month in the basic charge, bringing it to $30.00 per month.
In a separate case, the utility is seeking approval to increase the rate it charges for natural gas service. If the case is approved as filed, residential natural gas customers using an average of 66 therms per month would see an increase of 10.4 percent, or $6.29, for a monthly bill of $66.92. This is an increase from $60.63. Avista is proposing that the increase begin on Sept. 1, 2025. The utility also is seeking an increase that would begin on Sept. 1, 2026. If approved by the commission, residential natural gas customers using an average of 66 therms per month would see an increase of 1.3 percent, or $0.88. The monthly bill would increase to $67.80, up from $66.92.
The utility said it is seeking the rate increases to pay for an increase in net plant investment. It said it also saw an increase in costs for distribution, operation, maintenance, administrative and general expenses for electric and natural gas operations.
The commission can approve, deny or modify the applications.
