Solar energy to power TC Energy renewable natural gas (RNG) interconnects – meter stations that measure the amount of gas being transported – is helping the company to work towards our net-zero commitment while also enabling the company to sell renewable energy to the local utility.

The Project will include the construction of approximately 4 kilometres (km) of pipe 324 millimeters in diameter for transporting natural gas. It will parallel the existing Canadian Mainline, and will start at the Saint-Sébastien Meter Station near route 133 and end at a new proposed valve and receiver site in the municipality of Pike River, near Chemin Molleur.
