Is Google hiding a data center project in North San Jose?

Advocates say Google is hiding a data center inside a planned research and development lab in North San Jose.

The tech giant’s plans at 5079 and 5087 Disk Drive call for demolishing an existing warehouse and parking lot to construct up to three research and development (R&D) facilities across nearly 483,000 square feet. Architectural blueprints for the facilities show an onsite substation and switching station with three transformers, multiple generator yards and more. The facilities would have a 250-megawatt capacity — enough to power 250,000 homes at any given time. The project is still in the early stages of review.
