Natural gas rates to drop for Intermountain Gas customers
BOISE (September 30, 2015) – Rates for customers of Intermountain Gas Company will
decrease an average 5.7% effective Oct. 1.
The Idaho Public Utilities Commission approved the company’s annual Purchased Gas Cost
Adjustment (PGA). Under the PGA, rates are adjusted up or down every Oct. 1 to account for
that portion of gas supply expense that changes every year.
Lower wholesale prices for natural gas and a decrease in transportation costs billed to
Intermountain by its supplier, Northwest Pipeline GP, contributed to this year’s reduction.
The $15.3 million passed on to customers is about a 6.1% decrease to customers who use
natural gas for space and water heating, a 3.56% decrease to those who use natural gas for
space heating only and a 5.6% reduction for commercial customers. The PGA portion of
customer rates will be reduced from the current 39.5 cents per therm to 32.8 cents per therm.
With the approval, Intermountain’s combined residential and commercial rates are 35% lower
than in 2005.
Other factors contributing to the lower rate include increased natural gas production and
Intermountain Gas’ management of its storage and firm capacity rights on its various pipeline
systems.
