Our Mission

Our Mission is to deliver clean, safe, affordable, and reliable energy solutions to our customers every day through exceptional service and a strong commitment to our communities.


Our Story

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

We were founded in 1997 by two entrepreneurially-minded executives that 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.

Each of Summit’s subsidiaries constructs and installs natural gas distribution systems with the goal of supporting economic development by providing clean-burning, safe and reliable natural gas to residential and commercial customers through exceptional customer service and commitment to community.

Overall, Summit entities serve approximately 100,000 customers and operate more than 5,400 miles of pipeline in Arkansas, Colorado, Maine, Missouri and Oklahoma.
