Document Description
- Issuance of an Authority to Construct for Emergency Backup Natural Gas Generators Sources 1 through 140 (S-1 through S-140). (Air District Application #31953).
On or about November 15, 2019, Microsoft Corporation submitted a small power plant exemption (SPPE) application for a small powerplant exemption for the proposed San Jose Data Center Project in San Jose, California, to the CEC. The Applicant proposed two single-story data center buildings, SCJ02 an SJC03 . The SCJ02 building will include 140 natural gas generators to provide backup power to the data center operation during interruptions of the electrical supply. In addition to emergency use, the generators will be operated up to 50 hours per year per engine for reliability-testing operation, and up to 459 hours per year per engine as part of
the Pacific Gas & Electric Company's Base Interrupted Program .
The SPPE Application was submitted to the CEC pursuant to Public Resources Code Section 25541. Section 25541 allows the CEC to exempt thermal powerplants with a generating capacity of up to 100 MW from its exclusive permitting authority under the Warren-Aiquist State Energy Resources Conservation and Development Act
(Warren-Aiquist Act) to approve or deny, applications for the construction and operation of thermal powerplants that will generate 50 MW or more of electricity.
It was found that the Backup Generators constitute the thermal powerplant at issue, they have a combined generating capacity of 99 MW, and no substantial adverse impact on the environment or energy resources will result from the construction or operation of the Backup Generators or the San Jose Data Center.
