NATURAL GAS
Consumption decreased and prices remained low in
FY20211
In Idaho, natural gas is supplied to customers by Avista Corporation, Dominion Energy, and Intermountain Gas
Company. Idaho is fortunate 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.

NATURAL GAS
Consumption
In 2020, overall consumption of natural gas in Idaho decreased approximately 1 percent. Residential customers
consumed roughly 3 percent less and commercial customers consumed roughly 7 percent less natural gas than
the previous year. Industrial consumption decreased slightly and consumption of gas for electric generation
increased over 4 percent. Use of natural gas as a vehicle fuel increased slightly over 10 percent but is less than 1
percent of overall consumption.

NATURAL GAS
Demand
The Northwest Gas Association (NWGA) forecasts demand for natural gas in the Northwest to grow at a rate of
approximately 1.0% per year.3 Forecast demand growth in the residential and commercial sectors is slightly less,
while industrial demand growth has dropped by half (from 0.5 to 0.2 percent/yr.). Demand for natural gas to
generate electricity is forecast to grow slightly, mostly when coal-fired generation plants are retired in the
region.
Several factors could impact demand for natural gas:
• Retirement of coal fired generation and increased use for generating electricity.
• 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). The Northwest
Power and Conservation Council (NPCC) forecasts show that commodity prices are expected to remain below
$5/Dth through 2050 (see Figure 2) at hubs where the Pacific Northwest sources its gas.

Production
There was approximately 108 Mcf of natural gas produced by the Snake River Oil and Gas Group in Idaho in
2020.4 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. Production in Idaho was
shut-in March through December 2020.
Snake River Oil and Gas Group operations include:
• Processing facility located at Willow Creek near Payette, Idaho.
• Six wells producing natural gas, condensate, oil, and other liquids in the Willow Creek drainage.
• Six shut-in wells and are no longer producing.

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. Recently, a number of biomass operations in the state have pursued
development of 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.
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 of this resource.
Summary
Idaho residential, commercial, industrial, and transportation users of natural gas realized benefits from low
natural gas prices and plentiful supply, this fiscal year. Lower than average natural gas inventories are
contributing to price volatility. 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.
