The TBC (Trans Bay Cable) project is of strategic importance for the development of the San
Francisco Bay region where the demand for power is constantly increasing.
In the USA Prysmian recently commissioned the Neptune cable in the New York area,
confirming its worldwide leadership in the submarine power link sector.
Prysmian Cables & Systems, a world leader in the energy and
telecommunications cables industry, has been awarded a contract for the design, supply
and installation of a high voltage DC submarine link between Pittsburg and San Francisco
(California - USA), by Trans Bay Cable LLC, a wholly owned subsidiary of Babcock & Brown.
The project, named TBC (Trans Bay Cable) is worth in excess of 125 million dollars for
Prysmian. Jointly with the Power, Transmission and Distribution division of Siemens, Prysmian will
provide
the first turnkey system including the engineering, production and installation of
two
200 kV DC cable interconnections, consisting of 80km of Extruded Submarine Cables
and 5 km of Extruded Land Cables (AC and DC), with a total transmission capacity of 400 MW.
With this project Prysmian further confirms its worldwide leadership in the strategic high
value added sector of submarine power cables and systems, with a strong order book up to 2009.
Recently Prysmian handed over the Neptune cable, a key submarine power connection in the New York
area as well as the Spain-Morocco connection. In the last five years Prysmian has completed more
than 30 submarine cable projects worldwide, among them Basslink, in Australia, the longest
submarine connection to date and the Italy-Greece link, the deepest ever. Prysmian is currently
executing important projects such as SAPEI, the 1000MW HVDC submarine cable transmission link
between Sardinia and the Italian peninsula, that once completed will be the world deepest, and the
GCCIA cable between Saudi Arabia and Bahrain
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 and provide a dedicated connection between the East Bay, which has excess electrical capacity
and transmission grid congestion, and the electrical 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.
Prysmian will install the submarine cables and the optical fibre data transmission cable
with its own cable-laying ship, Giulio Verne. Both the submarine HVDC and land cables required for
the link will be produced in the Italian plant of Arco Felice (Naples). The project is scheduled
for completion by the end of March 2010.
