The project applicant proposes to construct and operate a 396,914 square foot data center near an existing power plant and wastewater treatment facility. The project would consist of two single-story data center buildings. To provide reliable operation of the project in the event of loss of electrical service from the local electric utility provider, Pacific Gas and Electric Company (PG&E), the project includes 224 renewable natural gas (natural gas) generators each rated at 0.45 MW output capacity to provide electrical power to support the data center uses during utility outages, certain onsite electrical equipment interruptions or failure, and for load shedding, demand response and behind-the-meter resource adequacy ancillary services. The maximum electrical load of the project would be 99 MW, although the estimated load is 77 MW, inclusive of information technology (IT) equipment, ancillary electrical/ telecommunications equipment, and other electrical loads (administrative, heat rejection, and safety/ security). In addition, the project includes two Tier 4 diesel-powered generators (designated as administrative generators), with a 1.5 MW standby generator. 

Since the 2022 FEIR was certified, the City, as the Responsible Agency and local land use agency, has requested modifications to the supporting roadway improvements and utility infrastructure included in the 2022 Project. The project applicant is also proposing modifications to certain components of the proposed data center facility. Given the location of the proposed modifications from the City and project applicant, certain changes to the Santa Clara Valley Water (Valley Water) Purification Center parking lot facilities and relocation of the current small modular visitor center would also be triggered. All project modifications are evaluated in an Addendum.
