The 12 kV switchgear will consist of three 2000 A main buses, three 2000 A main breakers, two 2000 A bus tie breakers, and twelve 1200 A feeder breakers. The estimated dimensions of the site will be 250' x 200'. The substation will be enclosed by a seven foot fence with two 20-foot access gates opening on to Orchard Avenue. Additionally, in order to integrate the new substation into the existing system and relieve the current underground congestion along Orchard Avenue, the proposed scope additions include distribution design along Orchard Avenue and Ford Street and along Gobbi to the railroad. Other services offered to provide benefit to the City during the project include the California Environmental Quality Act (CEQA) Environmental Process and assistance in procuring, evaluating and installing a radio link from the Hydro Plant to the City Hall.
