First reported by SF Yimby, the San Jose City planning commission will this week consider Stack’s request to build two data centers on a plot at 2400 Ringwood Avenue and 1849 Fortune Drive in Santa Clara County.

The company is requesting to rezone the approximately 9.78-gross-acre site from the IP Industrial Park Zoning District to a TEC(PD) Planned Development Zoning District.

Stack aims to demolish two existing buildings totaling approximately 135,000 sq ft and construct two four-story data centers – known as SVY05 and SVY06 – totaling approximately 522,200 square feet (48,515 sqm), and a four-story 136,575 sq ft manufacturing building.

The company also aims to install a 100 MW electrical substation from Pacific Gas and Electric (PG&E). The site would include 39 backup generators – 36 3MW and three 1MW diesel-fired backup generators.

The planning commission is set to consider the request today (April 26) and the city staff has recommended approval for the application.

Stack acquired the two adjacent parcels in 2021 for a combined $40 million. The company’s SVY01 campus is next door and comprises two buildings. First announced in 2020, Building B was built around 2021.

Stack is developing a second Silicon Valley campus at the former Memorex headquarters. EdgeConneX and Skybox are also developing facilities at the historic Memorex site.

The company raised $250 million in securitized notes in March 2023 and said it would use the money to expand its footprint.

While there is high demand for data center capacity in the Silicon Valley area, lack of space and power remains a challenge for companies.

Vantage is looking to expand its footprint in San Jose close to a number of Google offices and warehouses. Last year Microsoft filed for permission for two data center buildings at Orchard Parkway; the cloud company is also planning two more buildings at Alviso Milpitas Road

2023 has also seen Amazon acquire a former insulation factory in nearby Santa Clara, possibly for a data center. US development firm Valley Oak Partners recently filed plans for a 90MW campus further north in Fremont.
