General Description of Project

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 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.
