The Northwest Transmission Line (NTL) is a 214 mile, 287-kV transmission line between Skeena Substation (near Terrace) and a new substation near Bob Quinn Lake. This new line provides a reliable supply of clean power to potential industrial developments in the area; provide a secure interconnection point for generation projects; and potentially assist certain northwest communities to access the electricity grid, rather than obtaining their power from diesel generators. The estimated cost of the project is between C$561m and $736m. In May of 2011 the Tahltan Nation signed agreement to support the NTL. Project includes $130m from Canada’s Green Infrastructure Fund (CGIF). BC Hydro granted Valard Construction owned by Quanta Services the contract for this project. In March 2012, BC Hydro and Kitsumkalum First Nation signed an impact benefit agreement to provide training, contracting, jobs and other economic opportunities related to the construction of the Northwest Transmission Line. With this agreement, BC Hydro has now signed agreements regarding the project with all eight First Nations and the Nisga’a Nation within the Northwest Transmission Line project region. The project involved the construction of 1,092 towers in mountainous terrain. The NTL connects the recently constructed 195 MW hydro facility on the Iskut river sponsored by AltaGas. The project was completed about one month early on July 23, 2014. The Imperial Metals Red Chris mine will be interconnected in the near future.
