Intermountain Gas files its annual Purchased Gas Cost Adjustment with Idaho Public Utilities
Commission

BOISE (Sept. 11, 2020) – Intermountain Gas Company has filed its annual Purchased Gas Cost
Adjustment with the Idaho Public Utilities Commission requesting permission to increase rates
for some customers and reduce rates for other customers for the period of October 1, 2020
through September 30, 2021.

The company proposes to increase the price of natural gas for residential customers by 3.6
percent, increase the price for general service customers by 4.29 percent, and increase the price
for large volume customers by 5.10 percent. Intermountain Gas also proposes to decrease the
price for transportation customers by 3.02 percent, decrease the price for T-4 demand charge
customers by 1.02 percent and not change the prices for T-4 transportation customers.

The proposed changes reflect: costs billed to the company from transportation providers,
replacement of long-term segmented Northwest Pipeline LLC capacity received from third
parties with firm Northwest Pipeline LLC capacity held directly by Intermountain Gas, an
increase to the company’s weighted average cost of gas, an updated customer allocation of gas-
related costs pursuant to Intermountain Gas’ purchased gas cost adjustment provision, the
inclusion of temporary surcharges and credits for one year relating to natural gas purchases and
interstate transportation costs from Intermountain’s deferred gas accounts, benefits generated
from the company’s management of its storage and firm capacity rights on various pipeline
systems, benefits associated with the sale of liquefied natural gas from the company’s facility in
Nampa, a portion of the costs accrued related to the company’s latest general rate case and the
recovery of deferred in-person customer payment fees.

application through Monday, Sept. 21, 2020. Comments can be submitted to:
