San José Data Center 04

Microsoft Corporation (Microsoft) proposes to build the San José Data Center campus (the project or SJDC 04) to be located at the northwest corner of the intersection of Orchard Parkway and Component Drive in San José, California (project site). The project would be located on two parcels of land, assessor parcel numbers 101-02-019 and 101-02-020. The two parcels would be merged through a lot adjustment/merger. The project would include two four-story data center buildings, each approximately 315,639 gross square feet; emergency backup generating facilities; recycled water storage, fire water storage, pipelines, and support buildings; building cooling equipment; an on-site substation and switching station; two potential distribution transmission lines; and ancillary support facilities. The project also includes the installation of off-site utility infrastructure and may include offsite intersection improvements within existing public right-of-way (off-site improvement areas). Off-site utilities include potable water, recycled water, fire water, stormwater and sanitary sewer pipelines. 

The total maximum electrical demand of the project would be 97.8 megawatts (MW). The Tier 4 diesel backup generating facilities with selective catalytic reduction and diesel particulate filters would consist of thirty-two 3 MW primary emergency generators, two 0.5 MW administrative emergency generators, and two 0.8 MW storage tank area emergency generators. The sole purpose of the backup generating facilities is to provide electrical power to support the data center campus operations in the event of loss of electrical service from the local electric utility provider, Pacific Gas and Electric Company.
