Document Description
The proposed Trans Bay Cable Project consists of installation of 55-mile-long High Voltage Direct Current (HVDC) cable in San Francisco Bay, from a terminus in the City of Pittsburg in Contra Costa County to a terminus in the City of San Francisco in the vicinity of Potrero Point. The direct current (DC) cable being proposed utilizes HDVC technology and is available from several manufacturers. This technology has been utilized in numerous projects around the world. DC power is different from High Voltage Alternating Current (HVAC) technology in significant ways. It is controllable in a manner that mimics generation on the power delivery end and functions independently of problems in the alternating current (AC) grid. It has negligible magnetic fields, no AC EMF in the HDVC cable and can be more easily and inexpensively buried underground or underwater. HDVC becomes cost effective when transmission efficiency and reduced cable cost, over longer distances, offset the efficiency losses and cost for the HVAC to HDVC Converter Stations. The proposed HVAC cable would be bundled with a separate metallic return cable and a fiber optic communication cable. The fiber optic cable will ensure reliable communication between the Converter Stations in Pittsburg and San Francisco.
