Project Description

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 California Energy Commission (CEC) has the exclusive authority to certify thermal power plants 50 megawatts (MW) and greater proposed for construction in California, including the infrastructure serving the plants such as such as electric transmission lines, fuel supply lines, and water pipelines. The two processes available to developers are the Application for Certification (AFC) and the Small Power Plant Exemption (SPPE).

The Application for Certification (AFC) is the standard licensing process for proposed power plant projects that fall under CEC’s jurisdiction. The CEC's power plant site certification program is a certified regulatory program under the California Environmental Quality Act (CEQA). It incorporates all state, local, and regional agencies’ requirements necessary for a plant to be constructed and operated. The CEC also coordinates its review with federal agencies that will be issuing permits.

The Small Power Plant Exemption (SPPE) process allows applicants with facilities between 50 and 100 MW to obtain an exemption from CEC’s jurisdiction and proceed with local permitting rather than requiring CEC certification. 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. Public Resources Code section 25519(c) designates CEC as the “lead agency”, in accordance with CEQA, for all facilities seeking an SPPE. In granting an SPPE, the CEC is not the final approval necessary for construction and operation of a project. Instead, if the CEC grants an SPPE, the responsible local land use authorities and other agencies, such as the local air management district, will assume jurisdiction over the project under their respective permitting processes, and conduct any other necessary environmental review as “responsible agencies” under CEQA.

The AFC filing fee must be made when the project is submitted. There is also an annual compliance fee for projects granted a license.

The fee for filing an SPPE is the cost for the CEC to prepare the CEQA environmental document. A deposit is required at the filing. If the deposit exceeds the review cost, the remainder will be refunded. If the costs exceed the deposit, the applicant will be billed for the difference.
