Northtown Backup Generating Facility

Northtown Backup Generating Facility

The Northtown Backup Generating Facility (NTBGF) would consist of a total of forty two (42) diesel-fired generators that would be used exclusively to provide up to 97.3 megawatts (mw) of backup emergency generation to support Northtown Data Center (NTDC) to provide uninterrupted power for its tenants servers. The proposed project site is at the southwest corner of the intersection of West Trimble Road and Orchard Parkway in San José, California. The data center buildings, emergency backup generating facilities, project substation, water storage and treatment area, the PG&E; switching station, site circulation, and parking would be located on APNS 101-02-018 and 101-02-021. The entire project site is approximately 28.5 acres. The NTBGF would only provide interconnection to the NTDC and would not be interconnected to the transmission or distribution grid. The project would construct a new 115-34.5 kilovolt (kv), 110 mega volt-ampere (mva) electrical substation (project substation) adjacent to the proposed expansion of the recently permitted PG&E; utility. The two-bay project substation (two 105 mva 115kv - 34.5 kv step-down transformers and primary distribution switchgear) would be designed to allow one of the two transformers to be taken out of service, effectively providing 105 mva of total power (a 2-to-make-1 design) of the 42 total generators, two of the generators would each have a generating capacity of up to 1.75 mw and the remaining 40 generators would each have a generating capacity of 3 mw. Of those 40 generators rated 3 mw, eight would be redundant. The generators would be arranged in two generation yards located adjacent to each data center building (DC North and DC West). All 40 of the 3-mw generators would be dedicated to replacing the electricity needs of the data center in case of a loss of utility power, while the two 1.75-mw generators would be used to support general office loads along with building and life safety services (i.e., house generators) during emergencies.
