The proposed North Montney Mainline project will be a large diameter extension from the existing Groundbirch Mainline section of the NGTL system in northeastern British Columbia. It will consist of two sections, Aitken Creek and Kahta, totaling approximately 305 km (189 miles) in length, and will include associated metering facilities, valve sites and possible compression facilities. The project will also include an interconnection with TransCanada’s proposed Prince Rupert Gas Transmission (PRGT) project to provide natural gas supply to the proposed Pacific NorthWest LNG export facility near Prince Rupert, British Columbia.
Under the commercial arrangements with Progress Energy, receipt volumes will ramp up between 2016 and 2019 to an aggregate volume of approximately 2 bcf/d and delivery volumes to the PRGT project will be approximately 2.1 bcf/d beginning in 2019. NGTL is also in discussions with other parties that have expressed interest in obtaining transportation services that would use the North Montney Mainline facilities. The total cost for the North Montney Mainline project is estimated to be approximately $1.5 billion.
NGTL is continuing to advance its development work on the project, including field studies, engineering and design work, and pipeline routing to support applications for regulatory approvals and finalize project requirements. First Nations, landowner and community engagement and consultation activities for the North Montney Mainline project have commenced.
“The initial work for the project is proceeding well and we anticipate filing an application with the National Energy Board in the fourth quarter of 2013 for approvals to build and operate the facilities,” said Karl Johannson, TransCanada’s executive vice president and president, Natural Gas Pipelines. “If we receive the necessary approvals, we expect the Aitken Creek section to be operational in second quarter 2016, the Kahta section in second quarter 2017 and the export delivery facilities in 2019.”
