Power lines connecting Vancouver Island with Canadian Mainland

The power grid of Vancouver Island is owned and operated by BC Hydro, and is connected with that of the Mainland of British Columbia by high voltage AC submarine cables, and formerly by a DC submarine cable system. These links, which all consist of overhead line sections on land together with submarine cables are: Two parallel 500 kV AC circuits from south of Powell River to Vancouver Island in two cable and three overhead sections with reactor station on Texada Island, running from Malaspina substation near Sechelt to Dunsmuir substation near Qualicum Beach; Two AC lines, one 138 kV and one 230 kV, running from Arnott substation in Delta to Vancouver Island Terminal in North Cowichan (the same points that HVDC Vancouver Island connects).
