Summit Utilities

Summit Utilities, Inc. (Summit) owns natural gas distribution and transmission subsidiaries that operate in Arkansas, Colorado, Maine, Missouri and Oklahoma.

Our business began in 1997, when two entrepreneurially-minded executives recognized a need to deliver a more cost-effective and environmentally sustainable fuel option to residences and businesses in rural areas where other utilities could not or would not serve with natural gas. While the company started in Colorado with the founding of Colorado Natural Gas, Inc., it has since grown to provide safe, clean and affordable natural gas to businesses and residents in five states through Summit Natural Gas of Missouri, Inc., Summit Natural Gas of Maine, Inc. and Arkansas Oklahoma Gas Corporation.
