General Description of Project

Microsoft Corporation proposes to construct and operate the San Jose City Data Center (project) located at 1657 Alviso-Milpitas Road in San Jose, California. The project would consist of two single-story data center buildings with approximately 479,000 gross square feet of administrative and data center space. The electrical load of the project would be up to 99 megawatts, inclusive of information technology (IT) equipment, ancillary electrical/telecommunications equipment, and other electrical loads (administrative, heat rejection, and safety/security). The project would also include an onsite 115-kilovolt (kV) substation with two 115-kV electrical supply lines that would connect to PG&E’s Los Esteros Substation, located adjacent to the site. The California Environmental Quality Act (CEQA) requires the lead agency to consider the whole of the action; therefore, the Energy Commission will include the entire data center project in its analysis, which includes the construction of the data center buildings along with the installation and operation of the generators and any associated utility connection facilities.

Small Power Plant Exemption Evaluation Process

The SPPE process allows projects between 50 and 100 MW to proceed with local approval rather than requiring an Energy Commission license. This exemption from the Energy Commission licensing process can be applied to projects that would not create a substantial adverse impact on the environment or energy resources. The Energy Commission acts as the lead agency under the California Environmental Quality Act (CEQA) and will prepare an Initial Study and Mitigated Negative Declaration that examines public health and safety, along with environmental impacts of the proposed project, including all related facilities such as electric transmission lines, natural gas and water pipelines. If the exemption is granted, the applicant would still need to secure the appropriate licenses and permits from relevant local, state, and federal agencies.
