Avista is asking Idaho regulators for two rate adjustments that, if approved, would result in a slight net reduction in electric rates.
The Spokane-based utility has asked the Idaho Public Utilities Commission for the new rates to be effective Oct. 1.
Utility officials said the requested changes reflect differences between Avista’s cost of generating and purchasing electrical power and the cost currently reflected in customer rates, as well as a slight reduction in credits from the federal hydropower system that benefit residential utility customers.
If approved, a typical household using 910 kilowatt hours of electricity per month would see its monthly bill decrease from $88.49 to $87.79, a 70 cent reduction.
The proposed changes are separate from Avista request earlier this month for decreases in electric and natural gas rates based on higher-than-expected company revenues in 2017, which would be effective Oct. 1.
