Columbia Gas Transmission Modernization Program

Overview

TC Energy’s ongoing modernization of its Columbia Gas Transmission system consists of more than $2.5 billion in system enhancements. The work done under this program has led to improvements in reliability of service, integrity of assets and efficiency of operations—all while reducing emissions.

Consistent with TC Energy’s sustainability focus, our efforts to address greenhouse gas emissions on the Columbia system have resulted in 258,000 tonnes of total CO2 equivalent (CO2e) emissions avoided since this cycle of investment was initiated in 2013—equivalent to taking 56,000 cars off the road. Based on the work currently completed, it’s estimated that 57,000 tonnes of CO2e emissions will continually be avoided on an annual basis.

This trend is expected to continue over the next several years amid a proposed third phase of the modernization program.
