Evaluating three alternatives for proposed electrical transmission lines to southern Vancouver Island

This study evaluates three proposed alternative electrical transmission projects to Vancouver Island in terms of financial and non-financial characteristics. The three proposals differ in financing, technology, route, and regulatory frameworks. For establishing reliability and meeting future electricity needs, the Vancouver Island Transmission Reinforcement (VITR) Project is the least costly alternative, but will likely not be operational to meet the required in-service date and may encounter continued opposition from special interest groups. The Juan de Fuca (JDF) Project could likely be completed on time, and provide both reliability benefits and export potential. A preliminary financial analyses indicate that the VITR and JDF Projects are complementary; if both projects are constructed, net present value of the benefit to BC Ratepayer/Taxpayers is between $50 and $450 million. The JDF Project would also allow BC Hydro to avoid transmission congestion near Seattle, and thus increase the efficiency of electricity trade with the Pacific Northwest.
