Project Description

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.

Small Power Plant Exemption

The CEC has the exclusive authority to certify all thermal power plants 50 megawatts (MW) and larger and related facilities proposed for construction in California. The Small Power Plant Exemption (SPPE) process allows applicants with facilities between 50 and 100 MW to obtain an exemption from CEC’s jurisdiction and proceed with local permitting rather than requiring CEC certification. CEC can grant an exemption if it finds that the proposed facility would not create a substantial adverse impact on the environment or energy resources. Public Resources Code section 25519(c) designates CEC as the “lead agency”, in accordance with the California Environmental Quality Act (CEQA), for all facilities seeking an SPPE. In granting an SPPE, the CEC is not the final approval necessary for construction and operation of a project. Instead, if the CEC grants an SPPE, the responsible local land use authorities and other agencies, such as the local air management district, will assume jurisdiction over the project under their respective permitting processes, and conduct any other necessary environmental review as “responsible agencies” under CEQA.
