Bay Corridor Transmission and Distribution

The San Francisco Public Utilities Commission Power Enterprise is building a high voltage transmission and distribution system in the Southeast portion of the City. It is intended to serve existing and future customers with large power needs. There are three components to the Bay Corridor Transmission and Distribution project. The contracts are Design-Build (DB) in which SFPUC staff creates the fundamental design and the contractor completes the design and builds the project. Construction began in Fall 2020 and continues through 2024.

The following components of the project have been completed:

• DB-129.1 -- Terry Francois Boulevard and Illinois Street Water and Power System Improvements -- Warriors Way to Mission Rock Street -- extends the underground electrical duct banks and vaults south along Illinois Street from 23rd Street to the northern limits of the existing Islais Creek, as well as north along Terry A. Francois Boulevard to Mission Rock Street. In addition, DB-129.1 is building an extension of the Auxiliary Water Service System (AWSS) a high-pressure pipeline for firefighting along Terry Francois Boulevard between Warriors Way and Mission Rock Street.


• DB-129.2 -- Illinois & Marin Streets to Davidson Avenue -- Power System Improvements -- extends the underground electrical duct banks and vaults south of the existing Islais Creek, along parts of 3rd Street, Arthur Avenue, Cargo Way, Davidson Avenue, Evans Avenue, Quint Street and Rankin Street.

The following component is under construction and expected to be completed in 2024:

• DB-130 -- 1535 Davidson Avenue -- Power Distribution System -- builds a new electrical substation at 1535 Davidson Avenue. In addition, the contractor for this project will pull the wire for DB-129.1 and DB129.2, starting at Mission Rock Street and Terry Francois Boulevard and continuing to the new substation.
