Homestead Substation Rebuild Project

Project Specifications

Client: City of Santa Clara

Location: Santa Clara County

Services: Environmental Review & Permitting, Cultural Resources

Under Aspen’s environmental services on-call contract, Aspen prepared an IS/MND on behalf of Silicon Valley Power (SVP) for the proposed Homestead Substation Rebuild Project, which would rebuild the existing Homestead Substation within the existing substation site in the City of Santa Clara. The project would replace the existing substation in its entirety and would increase substation capacity to deliver 12 kilovolt (kV) distribution power within the substation’s service area. An existing 60 kV transmission line provides power to the substation; the line would be relocated within the substation property and unneeded poles and conductor would be removed.

Because the substation is approximately 50 years old, Aspen performed an evaluation of the site and substation based on historic records. Aspen’s evaluation concluded that the facility does not meet the established criteria to be considered as an historic resource eligible for inclusion on the State or Federal Register of Historic Places, meaning it is not considered a historical resource under CEQA. The Draft IS/MND was published in November 2022 and the Final IS/MND was published in March 2023.
