Acquired by TC Energy in 2016, the Columbia Gas Transmission system extends from New York state to the Midwest and Southeast, serving as a link between major natural gas basins and major markets. Thanks to the network’s 11,500 miles (18,500 km) of pipeline and dozens of storage fields in multiple states, Columbia Gas Transmission ensures the heat stays on and businesses stay powered, even when demand spikes.
