Idaho Power is seeking rate changes that would provide the typical residential customer 59 cents in savings per month.

     The utility filed its most recent power cost adjustment on April 15 with the Idaho Public Utilities Commission. The cost-adjustment filing is one of four recently submitted to the PUC. Two are for cost increases. All four would need to be approved to provide the 59-cents-a-month savings, according to Idaho Power.

     If only the recent power cost adjustment is approved, the savings would be $3.35 per month for a residential customer.

     The other three adjustments are:

  • An annual fixed-cost increase that changes prices due to fluctuation in energy use per customer in the past year;
  • A rate increase related to recovering costs from Idaho Power’s scheduled exit from the North Valmy coal-fired power plant;
  • A downward adjustment related to the Idaho Energy Efficiency Rider.

     PUC spokesman Matt Evans said the commission has approved all of Idaho Power’s annual proposals since 2015.

     Evans said the intent of the fixed-cost adjustment is to decouple revenue from energy use, to promote energy efficiency and ensure that the company doesn’t lose money when that use goes down.
