Pipeline owners are meeting growing demand for natural gas by expanding capacity on existing infrastructure.
The Federal Energy Regulatory Commission issued on June 30 a draft environmental review of a proposed capacity expansion of TC Energy’s Gas Transmission Northwest pipeline between Idaho and Oregon (pictured) that found minor, temporary and localized effects. The $335-million project would increase capacity by about 150 million cu ft/day on the 1,377-mile pipeline by increasing compression, replacing turbines and other upgrades to enable transport of more Canadian natural gas to the Pacific Northwest in late 2023.
