The Lafayette Data Center project (LDC) would include demolition of existing improvements on a 13.04-acre site to construct a three-story 576,120 square foot data center building, utility substation, generator equipment yard, surface parking, and landscaping. The data center building will house computer servers for private clients in a secure and environmentally controlled structure and would be designed to provide 66 megawatts (MW) of power to information technology (Critical IT) equipment. Power to run the LDC would be provided by Silicon Valley Power. Backup generation capabilities in the event of a disruption of grid power would be provided by the Lafayette Backup Generation Facility (LBGF), which would have a generation capacity of up to 99.8 MW to support the need for the LDC to provide uninterruptible power supply for its tenant’s servers. The LBGF would consist of 44 diesel-fired backup generators arranged in a generation yard located on the south side of the LDC. Project elements will also include switchgear and distribution cabling to interconnect the generators to the LDC.

Small Power Plant Exemption
The CEC Small Power Plant Exemption (SPPE) process allows applicants proposing thermal power plants between 50 and 100 MW to obtain an exemption from the CEC’s jurisdiction and proceed with local permitting rather than requiring CEC certification. The CEC can grant an exemption if it finds that the proposed facility will not create a substantial adverse impact on the environment or energy resources. These facilities were exempted from the CEC’s jurisdiction.
