The Globe and Mail reports in its Tuesday edition that Coastal GasLink, a natural gas pipeline partnership operated by TC Energy, is seeking $1.2-billion from one of its main contractors for construction delays and may be liable for a similar amount if an arbitrator rules TC's way, court documents showed ahead of a hearing this month. A Reuters dispatch to The Globe says that construction of $14.5-billion Coastal GasLink, which TC began planning in 2012, finished in October at more than double its original budget. Private equity firm KKR & Co. and Alberta pension manager Alberta Investment Management Corp. (AIMCo) jointly own 65 per cent of the limited partnership and TC owns the remaining 35 per cent. The dispute over the project that will supply Canada's first liquefied natural gas export terminal around 2025 highlights the extreme difficulties operators face in building Canadian pipelines. The Canadian government-owned Trans Mountain pipeline expansion, which aims to boost oil exports, has also faced delays and soaring costs. The 670-kilometre Coastal GasLink through the B.C. Rockies to the Pacific coast was delayed by mudslides, a six-month pandemic work stoppage, sometimes violent protests and steep terrain.
