Intermountain Gas Company files decrease in prices as part of annual PGA

BOISE, ID – August 15, 2019 – Intermountain Gas Company filed its annual purchased gas cost adjustment (PGA) application with the Idaho Public Utilities Commission to change its prices by an average decrease of 0.5% or approximately $1.1 million. If approved, the decrease would be effective Oct. 1, 2019.

The primary reason for the proposed decrease is continued low natural gas prices and the company’s management of its pipeline capacity contracts. Because the price of natural gas is a pass-through charge directly to its customers, Intermountain’s earning will not decrease because of the proposed change in prices and revenues.

If approved, residential customers will see a small average decrease of 0.8 % or $0.29 per month based on average weather and usage. Commercial customers, on average, would see a slight increase of 0.20 % or $0.27 per month.

“We are proud that we have been able to maintain declining prices for the fifth straight year,” said Scott Madison, executive vice president, business development and gas supply.

A copy of the application is available for review at the commission, its homepage, as well as the company’s website Written comments regarding the application may be filed with the commission.
