History

Columbia Gas traces its heritage from 1885 and has a long-standing a commitment to powering 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 American Dream at the dawn of a new century.

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.
