The Trans Bay will be a submarine energy connection (HVDC) between the cities of Pittsburgh and San Francisco, in California, from Trans Bay Cable LLC. Prysmian will provide the “ turnkey” system including the engineering, production and installation of two 200 kV DC cable interconnections, consisting of 80 km of Extruded Submarine Cables and 5 km of Extruded Land Cables, with a total transmission capacity of 400 MW. The TBC project is of strategic relevance to the development of the San Francisco Bay region where the demand for power is constantly increasing. The project is designed to transmit electrical power between the East Bay, which has excess electrical capacity and transmission network congestion, and the power transmission and distribution facilities in San Francisco. TBC is a cost effective, energy efficient solution, addressing San Francisco’s needs for additional transmission capacity, while improving transmission reliability and load serving capability. In addition, it has the potential to allow for the removal of in-city generation facilities thus eliminating related air emissions. The project is scheduled for completion by March 2010.
