TransCanada to expand mainline system capacity
August 8, 2017
TransCanada Corporation is applying to the National Energy Board (NEB) to expand the capacity of the Canadian Mainline System through its Maple Compressor Station in Vaughan, Ont. to meet growing demand over the long term.
The $160-million project is supported by 15-year contracts and will increase capacity to the southern Ontario market plus delivery to Atlantic Canada via the Trans Quebec and Maritimes Pipeline and Portland Natural Gas Transmission systems, states a media release.
The proposed project will add incremental compression and associated facilities on the Canadian Mainline to move an additional 80-million cubic feet of clean-burning natural gas per day, which is enough to supply more than 300,000 homes on an annual basis, states TransCanada.
"This investment further affirms our commitment to build key natural gas infrastructure in Canada and shows the importance of the Canadian Mainline to efficiently and competitively meet the transportation needs of our customers," said Karl Johannson, TransCanada's executive vice-president and president, Canada and Mexico natural gas pipelines and energy, in a statement.
An application to approve the associated facilities is expected to be filed with the NEB in early 2018, to meet a Nov. 1, 2019 in-service date, once TransCanada has completed its tariff process for capacity additions. This new investment is part of a $500-million program that TransCanada is undertaking to support additional transportation of Canadian and U.S. gas along the company's Canadian Mainline system.
