Natural Gas Operations


Natural gas plays a critical role in the global energy transition. It is a reliable, high-efficiency energy source that is displacing coal-fired power while backstopping the intermittency of renewable power sources.

We build and operate safe and reliable energy infrastructure. This includes our 93,600 km (58,100 miles) network of natural gas pipelines, which supplies more than 30 per cent of the clean-burning natural gas consumed daily across North America to heat homes, fuel industries and generate power.

Learn more about our natural gas projects and assets, including pipelines and storage, and more below.
