NATURAL GAS
Consumption and prices increased in FY20221
In Idaho, natural gas is supplied to customers by Avista Corporation, Dominion Energy, and Intermountain Gas
Company. Idaho is fortuitous to be located between two large natural gas producing basins: The Rocky
Mountain Basin (Rockies) and the Western Canadian Sedimentary Basin (WCSB).
These basins are connected through the Williams Northwest Pipeline and TransCanada’s GTN pipelines allowing
the natural gas utility companies serving Idaho to take advantage of capacity and of pricing at both basins.

Consumption
In 2021, overall consumption of natural gas in Idaho increased approximately 2.3 percent. Residential customers
consumed roughly 0.3 percent more and commercial customers consumed roughly 2 percent more natural gas
than the previous year. Industrial consumption decreased approximately 1.3 percent and consumption of gas for
electric generation increased just under 10 percent. Use of natural gas as a vehicle fuel increased slightly and
remains less than 1 percent of overall consumption in the state.

Demand
The Northwest Gas Association (“NWGA”) forecasts demand for natural gas in the Northwest to grow at a rate
of approximately 0.2 percent per year.3 Forecast demand growth is 1 percent in the residential and 1.4 percent
commercial sectors, while industrial demand growth is relatively flat at 0.2 percent per year growth. Demand for
natural gas to generate electricity is forecast to drop -1.7 percent per year primarily due to policy mandates.
Several factors could impact demand for natural gas:
• Geopolitical issues and worldwide market demands.
• LNG and petrochemical production and exports.
• Energy policies, regulations, and legislation.
Prices
Over the last decade, the commodity price of natural gas has continued to decline (see Figure 1). However, near-
term volatility resulted in higher prices in 2021. Regional natural gas spot prices are projected to remain below
$5/dekatherm (“Dth”) through at least 2040; depending on the source, some prices are forecast to remain
below $4/Dth through 2050.

Production
There was approximately 1331 Mcf of natural gas produced by the Snake River Oil and Gas Group in Idaho in
2021.4 In years prior to 2019, gas was produced by Alta Mesa/High Mesa. Snake River Oil and Gas Group
purchased Alta Mesa/High Mesa wells and production facilities in December 2019.
Renewable Natural Gas (RNG)
RNG is pipeline-quality biomethane produced from biogas. Biogas is the mixture of gases produced by the
breakdown of organic matter in the absence of oxygen (anaerobically), primarily consisting of methane and
carbon dioxide. It can be produced from raw materials such as agricultural waste, manure, municipal waste,
plant material, sewage, or food waste. It is interchangeable with natural gas and compatible with the U.S.
natural gas infrastructure. In the past, RNG projects in the state consumed gas produced in their operations or
used the gas to generate electricity. A number of biomass operations in the state have capabilities to produce
sufficient volumes of RNG for export onto pipeline infrastructure. On a per therm basis, RNG is more expensive
to produce than traditional natural gas. Given current State and Federal Government policies and programs
some RNG projects have the potential to achieve profitability.
Some natural gas utility companies in the state are facilitating the transportation of RNG and the growth of the
RNG industry. Producers contract to use the utility’s distribution system to move RNG from the producers to
their end use customers. The utilities are monitoring RNG production activity and government policies as they
continue to look for opportunities to participate in the development and expansion of this resource.

Summary
Idaho residential, commercial, industrial, and transportation users of natural gas realized benefits from
availability of natural gas and relatively low prices, this fiscal year. Price volatility and lower than average natural
gas inventories are contributing to market fluctuations. It is anticipated that domestic natural gas production
will outpace LNG exports in the second calendar quarter of 2022 reducing volatility and putting downward
pressure on prices.

THE FOLLOWING ARE PRESS RELEASES FROM THE COMMISSION FOR
FISCAL YEAR 2022
Intermountain Gas Company
Commission approves Intermountain Gas application to increase rates for residential and
commercial customers
On July 29, 2022, the Idaho Public Utilities Commission approved new Intermountain Gas Company rate
schedules through an interim Purchased Gas Cost Adjustment (PGA) that increases rates for natural gas service
for residential customers by approximately 24.1 percent and rates for commercial customers by approximately 27
percent.
The rate increases started on Aug. 1, 2022. Residential customers’ monthly bills will increase by an average of
$10.55 and commercial customers’ bills will increase by an average of $51.87, depending on the amount of
natural gas they use. In total, annualized revenues for the Company will increase by $67 million. The customer
rate increases will not increase the Company’s earnings.
The PGA is a Commission-approved mechanism that adjusts rates up or down to reflect changes in the costs for
the Company to buy natural gas from suppliers – including changes in transportation, storage and other costs.
Intermountain Gas defers those costs into its purchased gas cost adjustment account, then passes the costs on to
customers through a rate increase or decrease.
Intermountain Gas asked for permission to pass through to each of its customer classes changes in gas-related
costs resulting from an increase in its weighted average cost of gas, and received approval to increase the cost
from $0.26000 per therm to $0.42405 per therm. Intermountain Gas said the primary drivers of the proposed
increase include macroeconomic forces and geopolitical events that are increasing the price of wholesale natural
gas.
Intermountain Gas also asked for permission to increase its line break rate increase from $0.42443 per therm to
$0.58848 per therm for parties responsible for damage that causes a gas
leak.
Staff with the Idaho Public Utilities Commission reviewed the application and recommended that the Commission
approve it.
Although the Commission approved Intermountain Gas’s requested PGA rate increases, it encouraged the
Company to explore all options to reduce future increases.
