Prologis San Jose Wastewater Facility Campus

Prologis's proposed four-building data center campus (about 396 MW per press) on 159 acres of city-owned land beside San Jose's wastewater plant, with 250 MW committed by PG&E

Developer picked, early stage. San Jose's council chose Prologis as preferred developer on Nov. 18, 2025 and authorized exclusive negotiations. No signed negotiation agreement, ground lease, planning application or environmental review is on record as of Oct. 2026.
