General Description of Project

The Mission College Data Center (MCDC) site is located at 2305 Mission College Boulevard within the City of Santa Clara. The project would include construction of two, three-story data center buildings encompassing a total square footage of 490,000, and a backup generating facility with a generation capacity of up to 78.1 MW to support the need for the MCDC to provide uninterruptible power supply for its tenant’s servers. The generation facility will consist of 43, 2.5 MW diesel-fired emergency backup generators, arranged in two generation yards, each designed to serve one of the two data center buildings that make up the MCDC. Project elements will also include switchgear and distribution cabling to interconnect the two generation yards to their respective buildings. Two house power diesel fired generators, each capable of generating 600 kW to support its respective building phase in an emergency, are also proposed. The MCDC will be supplied electricity by Silicon Valley Power (SVP) through a new distribution substation constructed by Oppidan in the northeast corner of the MCDC site and to be owned and operated by SVP.

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.
