About Columbia Gas of Maryland

Columbia Gas traces its heritage from 1885 and a commitment to power the American experience. We lit the cobbled streets and immigrant dreams of the 1890s, fueled the steel-making blast furnaces of a nation expanding, and powered the lives and imaginations at the dawn of a new American Century.

It’s in keeping with our mission as the region’s premier natural gas distribution company, delivering clean, pure natural gas to homes, businesses and industry through our network of underground pipelines. The integrity of that network is a top priority.

Today, our second century of commitment forges ahead, investing in our region’s infrastructure to expand, rebuild and install hundreds of miles of state-of-the-art gas lines serving more than 33,000 customers in Garrett, Allegany and Washington counties. And in its wake, new jobs, economic impact, community revitalization, and the assurance of a steady, reliable, safe flow of the energy of the future…natural gas. 

Columbia Gas of Maryland is one of 10 energy distribution companies of NiSource Inc. (NYSE: NI). NiSource distribution companies serve 3.8 million natural gas and electric customers primarily in nine states.
