Intermountain Gas

Intermountain Gas Company firmly believes in contributing to the support of the communities they serve. Energy costs can be one of the major factors in a business's decision to expand or relocate its operations. Intermountain Gas has a commitment to provide their customers with cost-effective, clean, and efficient energy source for their business needs.

Intermountain assists commercial and industrial businesses with solutions to their energy needs, by providing a number of specialized services including customized cost modeling and comparisons to alternate energy sources.


The Intermountain Gas Company story began in 1950 when Nat and Myrtis Campbell read a newspaper article that piqued their interest in the natural gas industry. The company was incorporated that year. After five years of hard work laying the foundation for a new public utility company, Intermountain Gas Company received certification from the Idaho Public Utilities Commission on December 10, 1955. Then, on December 31, 1955, we connected our first five customers.
