Idaho can boast some of the lowest natural gas prices in the country. The Williams Pipeline, running through southern Idaho, connects with extensive gas fields in Canada, Mexico, and the Western U.S. And, thanks to this supply, both commercial and residential natural gas users find Idaho rates very competitive.

Overall energy costs are impacted by a variety of factors, including regulation, taxes, government mandates, economic growth and development of resources. With a business friendly regulatory environment and continued development of a diverse range of energy sources, Idaho has the second lowest energy costs of any state in the nation.
