This 247-km, 500-kV transmission line will extend from Merritt to Coquitlam, delivering power to BC’s Lower Mainland and Vancouver Island, which will deliver power to more than 1.4 million industrial, commercial, and residential customers. Increasing demand, changing patterns of use, and aging equipment have put pressure on the transmission grid, which continues to operate reliably but is reaching capacity in some areas. Conductor stringing commenced in summer 2014. The project will be completed and in service in 2015.
