NEWS RELEASE: Commission approves proposed settlement that will allow natural gas utility
to increase rates.
BOISE (Dec. 31, 2025)—The Idaho Public Utilities Commission has approved a proposed
settlement that will allow Intermountain Gas to increase rates for its residential and general
service commercial customers.
The average residential customer's monthly bill will increase by $2.45, an increase of 6.02
percent. The average general service commercial customer's monthly bill will increase by $4.42,
or 2.46 percent. The settlement also includes an increase in the monthly residential customer
charge to $11.00, an increase of$3.00. The general service commercial customer will see an
increase of$8.00, bringing the monthly charge to $23.00.
The new rates take effect on Jan. 1, 2026.
In its initial application, Intermountain Gas had asked to increase the average residential
customer bill by $4.69 and increase the average general service commercial customer bill by
$9.26. The utility sought the rate increases to pay for operation and maintenance costs that have
increased by an average of 5.3 percent since the utility's last rate case and to pay for investments
made in infrastructure.
The Commission issue an order approving the settlement on Dec. 30, 2025. It determined the
settlement allows Intermountain Gas to operate sustainably while protecting customers from a
rate increase that would be burdensome.
