HVDC Vancouver Island is a de-energized high-voltage direct current interconnection owned by BC Hydro that runs between Arnott Substation (ARN) in Delta, British Columbia at 49°5′31″N 123°2′31″W / 49.09194°N 123.04194°W on the Canadian mainland, and the Vancouver Island Terminal (VIT) in Duncan, British Columbia on Vancouver Island at 48°49′39″N 123°42′55″W / 48.82750°N 123.71528°W. It went into operation in 1968 and was extended in 1977. HVDC Vancouver Island consists of three overhead line sections with a total length of 42 km (26 mi) and two submarine cable sections with a length of 33 km (21 mi). There were two 600 amp cables for Pole 1, one 600 amp cable for neutral current return, and two 900 amp cables for Pole 2. Pole 1 ceased operation in 2014, and Pole 2 ceased operation in 2016. The infrastructure remains in place and portions may be re-used in the future.
