Trans Bay Cable is a public private partnership that will provide San Francisco with a new source of electricity, without having to install a power generation plant.
The project will transmit existing power between the transmission grid in the East Bay, which has excess electrical capacity, and the electrical transmission and distribution grid in San Francisco.


SteelRiver Infrastructure Partners is responsible for the construction and financing of the project in cooperation with the City of Pittsburg and Pittsburg Power Company.
Trans Bay Cable will reduce the need for in-city generation in the City of San Francisco, and increase the overall security and reliability of the electrical system.
Once in operation, Pittsburg Power Company will take ownership of the Trans Bay Cable assets.
