Idaho Power files annual Fixed Cost Adjustment

Idaho Power

IDAHO FALLS, Idaho (KIFI) - Idaho Power has filed the first of two annual cost adjustments with the Idaho Public Utilities Commission (IPUC). This year’s annual Fixed Cost Adjustment (FCA) requests a decrease of $10 million, or 1.56%, for residential and small general service customers in Idaho.

If the FCA proposal is approved as filed, a typical residential customer using 950 kilowatt-hours per month would see about a $1.66 decrease to their monthly bill beginning June 1. However, the final impact to customer bills won’t be known until a second annual adjustment, the Power Cost Adjustment (PCA), is filed in April.

The FCA adjusts prices up or down based on changes in energy use per customer during the prior year. It is a true-up mechanism that separates energy sales from revenue to remove financial disincentives for Idaho Power to invest in demand-side management, which can contribute to use per customer declining.

In 2022, Idaho Power’s energy efficiency programs saved 169,889 megawatt hours — enough energy to power about 14,900 average-sized homes for a year. Idaho Power values demand-side management, energy efficiency and education programs, and the FCA allows the company to provide these programs to residential and small general service customers without negative financial impacts.

The FCA allows Idaho Power to recover an IPUC-authorized level of fixed costs — costs associated with things like generation plants, power lines and substations — per customer. If the company collects less than the authorized fixed-cost amount, it can collect the difference through a surcharge. If the company collects more than the authorized amount, it refunds the difference to customers through a credit.

Chinden Blvd. Building 8, Suite 201-A, Boise, ID 83714) Idaho Power offices, on, or at the IPUC website, Customers may also subscribe to the IPUC’s RSS feed to receive periodic updates via email about the case.
