BC Hydro says extreme June heat may be to blame for damage to three submarine cables that provide power to Vancouver Island from the mainland. Power lines are pictured on rural Vancouver Island. Electricity is delivered to the island through a system of submarine cables running underneath the Salish Sea from the mainland. Hi there, we want to let you know we're not currently asking customers on Vancouver Island to reduce their electricity use. Seventy to 80 per cent of the province's electricity is consumed in the Lower Mainland and on Vancouver Island.
