STACK SVY03A Data Center Campus

STACK Infrastructure is proposing to develop the SVY03A Data Center Campus (campus), which would be located in the City of Hayward at 26203 Production Avenue.  The proposed campus would include a three-story data center building, a one-story data center building, backup generators to support both data centers, a security building, an on-site project substation, and a Pacific Gas and Electric Company switching station. The campus would also include new site and infrastructure improvements consisting of new access driveways located at Eden Landing Road and Production Avenue, internal circulation improvements, parking, a loading dock, stormwater basins, landscaping, utilities, water tank, and a perimeter security fence. The backup generators would have a total generation capacity of up to 76.6 megawatts (MW). A total of 28 emergency generators would be arranged in two generation yards, with 26 2.75 MW generators and a single 1 MW generator serving the larger data center building, and a single 1.6 MW generator serving the smaller data center building. The generators would be dedicated to replace the maximum electricity needs of the campus in case of a loss of utility power and would only serve the campus and its components. Included in the total number of generators are redundant generators to ensure the maximum electricity needs (76.6 MW) of the campus would be maintained in a disruption of utility power.
