Columbia Gas Transmission Modernization Program

Natural Gas Icon


Modernizing our Columbia Gas Transmission pipelines means more than ensuring natural gas safely gets to market. By replacing steel pipe, upgrading compression facilities and integrating cutting edge maintenance technology at hundreds of sites, we’re on track to cut greenhouse gas emissions by about 20,000 metric tons per year. Between 2013 and 2020, TransCanada will invest more than two billion dollars to make it happen.
