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

BOISE, IDAHO – August 10, 2018 – Intermountain Gas Company filed its annual Purchased Gas Cost
Adjustment (PGA) application with the Idaho Public Utilities Commission to change its prices by an overall average
decrease of 10.2 percent or approximately $24.5 million. If approved, the decrease would be effective Oct. 1, 2018.
The primary reason behind the proposed decrease is a decline in the price of natural gas that Intermountain
purchases for its customers. Because the price for gas is a pass-through charge directly to its customers,
Intermountain’s earnings will not decrease because of the proposed change in prices and revenues.

If approved, residential customers using natural gas will see an average decrease of 10.0 percent or $4.12 per
month based on average weather and usage. Commercial customers, on average, would see a decrease of 11.9
percent or $21.89 per month.

The company is also proposing to eliminate the temporary surcharges and credits that have been included in its
current prices during the past year. Newer temporary surcharges and credits will be included going forward.

“Because of industry-specific technological advances in exploration, production and energy efficiency
measures; nationwide supply of natural gas continues to outpace demand, which contributes to lower natural gas
prices,” said Scott Madison, executive vice president business development and gas supply. “In addition,
Intermountain continues its long tradition of prudent management of pipeline capacity and summer storage to
ensure the best prices for our customers. We are proud to offer some of the lowest prices for natural gas in the
region and country.”

Even with this proposed price decrease, Intermountain continues to urge all its customers to use energy wisely.
