Electric, natural-gas and telephone service can be provided by different types of utilities and corporate structures. Public, or regulated, utilities are sometimes also called investor-owned utilities. Other types of utilities include cooperatives and municipal utilities. Telephone service is increasingly difficult to categorize, as broadband, telephone and video services are often bundled and provided by a variety of carrier types.

The OCS is authorized to advocate only for residential and small commercial consumers of electric, natural gas and telephone public utilities. This section identifies which providers are public utilities and provides additional information about the different electric, natural gas, and telephone providers in the State of Utah.
