NEWS RELEASE: Electric Utility Files Annual Cost Adjustment Applications with Idaho Public
Utilities Commission
BOISE (May 4, 2026)—Idaho Power has filed two annual cost adjustment applications with the
Idaho Public Utilities Commission that, if approved as filed, would increase customer rates.
The utility filed its power cost adjustment(PCA) application and fixed cost adjustment(FCA)
application. The PCA allows Idaho Power to increase or decrease the PCA rates to reflect the
utility's annual costs of supplying power. Because the utility has a diverse generation portfolio,
its actual costs of providing electricity varies depending on factors such as river streamflow, the
amount of purchased power, fuel costs and the market price of power, among other factors. The
annual PCA is combined with Idaho Power's base rates to create a customer's overall energy
rate. The PCA can only be used to cover power supply costs. Neither Idaho Power or its
shareholders receive a financial return from the PCA.
The FCA annually adjusts rates up or down to recover the difference between the fixed costs
authorized by the Commission and the actual fixed costs Idaho Power recovers from customers
for the sale of electricity during the previous year. Fixed costs are a utility's costs to provide
service that do not vary with fluctuations in energy consumption. Variable costs change based on
the energy generated and consumed. The FCA applies to residential and small commercial
customers.
If approved as filed, the FCA and PCA would increase the average residential bill,based on 900
kilowatt-hours per month, by approximately $3.64 or 3.15%. Customers in small general service,
large general service, large power and irrigation customers would also see increases. The exact
amount will vary depending on the customer's rate category.
