It's Your Choice: Wyoming Natural Gas Suppliers

In Wyoming, residents are used to wide open spaces and the freedom to choose their own Wyoming natural gas supply companies. The program, called Choice Gas, opens up the natural gas marketplace once a year — three weeks each April. During this time you can stay with your current Wyoming energy supplier or choose a new natural gas supplier for the next year.

A resident whose utility is Black Hills Energy and lives in one of the following communities listed below can choose Wyoming Community Gas, the cooperative that Constellation is affiliated with.
