Datacenter Projects in California

California, led by Silicon Valley's Santa Clara cluster, remains a critical interconnection market despite power constraints. Activity is shifting toward retrofits, edge facilities, and Sacramento-area expansion.

California is currently tracking roughly 135 active datacenter projects across operational sites, builds under construction, and recently announced campuses, representing an estimated 2,000 MW of IT load capacity. Over the last 24 months, 18 new large-scale projects have been announced statewide, with approximate aggregate investment of $18B. The state is categorized as a primary market for North American datacenter activity.

Top Datacenter Markets in California

Datacenter construction in California is concentrated in Silicon Valley (Santa Clara), San Jose, Los Angeles, San Francisco, Sacramento. These submarkets attract activity because of available high-voltage transmission capacity, large industrial-zoned land parcels, favorable tax abatements, and existing fiber routes connecting to major peering hubs.
