Prologis files 516,000 sq ft data center

Prologis has filed plans for a 516,000-square-foot data center in South San Jose, adding a large compute project to a market already racing to line up power for artificial-intelligence infrastructure. Local reports published July 8 said the proposal calls for a three-story, 99-megawatt facility at 5977 Silver Creek Valley Road. (hoodline.com) NBC Bay Area reported the project would include about 30,000 square feet of office space, while Hoodline and The Registry said the filing also points to an on-site substation and transmission work. The filing matters because Prologis is better known as the world’s largest warehouse landlord than as a data-center developer. But the company now has a dedicated data-centers business and says on its website that it is targeting hyperscale digital infrastructure with development and energy solutions. (hoodline.com) ### Why is a warehouse landlord filing for a data center in South San Jose? Prologis has already been presenting itself as more than a pure logistics real estate owner. The company’s data-centers page says it is offering development, energy and location services for digital infrastructure, and its broader property business in the Bay Area includes South Bay industrial assets positioned near research, development and advanced manufacturing users. (nbcbayarea.com) The Registry reported in November 2025 that Prologis was planning to invest heavily in data centers, and Hoodline reported in January 2026 that San Jose had selected Prologis as preferred developer for a separate 159-acre site that could support data centers and advanced manufacturing. (prologis.com) Those earlier reports suggest the Silver Creek Valley Road filing is part of a larger push already underway in San Jose. ### What stands out most in this filing? The 99-megawatt power figure is the detail that makes this proposal different from an ordinary industrial redevelopment. Hoodline said the South San Jose project would require an on-site substation and transmission work, and The Registry said the plan is backed by a dedicated PG&E substation and new transmission lines. (prologis.com) South San Jose has already been seeing industrial sites reworked around power availability. Hoodline reported last week that Prologis also has a separate plan to convert a 302,843-square-foot warehouse at 5853 Rue Ferrari into a 49-megawatt research-and-development and server-ready facility. (news.theregistrysf.com) ### How does this fit into San Jose’s broader data-center buildout? San Jose has been trying to increase power capacity for data-center growth. NBC Bay Area reported last year that the city announced a partnership with PG&E to address rising electricity demand, and in January the station reported Equinix had energized a new San Jose data center under that partnership. (hoodline.com) Microsoft also broke ground in June on a 48-megawatt data center campus in San Jose’s Alviso neighborhood, according to NBC Bay Area. Measured against that project, Prologis’ proposed 99-megawatt facility would rank among the larger recent compute developments disclosed in the city. (hoodline.com) ### What do we actually know about the building itself? NBC Bay Area said the building is proposed to rise three stories and include 30,000 square feet of office space. Hoodline said the project would sit on a 15-acre site, and both Hoodline and The Registry identified the address as 5977 Silver Creek Valley Road. (nbcbayarea.com) There is no public start date yet. NBC Bay Area said there was no update on when construction would begin or when the center would open, and the next concrete milestones are likely to come through city entitlement records and utility-related filings tied to the substation and transmission work.
