The largest concentration is Santa Clara, with 101 data centers, followed by San Jose with 55 and Los Angeles with 50. The operators with the most data centers in California are Lumen (43), Digital Realty (28), Equinix (27), Cogent (14), Centersquare (14). Colocation and interconnection providers appear most often because they publish building-level detail; hyperscale campuses appear where the operator or the county names the individual buildings. Not every operator discloses size. In California, 126 publish a floor area and 60 publish a power figure, and each figure is shown against the data center it belongs to rather than added into one number. They are not the same measurement: one operator states the floor area of a single building, another the full capacity of a campus it has only announced. CAISO runs the wholesale power market and the high-voltage grid for most of California. 2 statewide measures governing data centers are on record, alongside 8 local pauses. 9 named projects in California are delayed, blocked or under challenge, and the capital atlas records 8 sites here. The list ## California data centers by city Every data center identified in California, grouped by the city or county it stands in, 482 of them across 82 places. Each entry names the operator and links to the source that states it. ### Data centers in Santa Clara, California Santa Clara, California has 101 data centers on this map, run by Digital Realty, Centersquare, CoreSite and Vantage. 45 publish a floor area and 27 publish a power figure, shown against each one below. 1.

The industry reference count for California is 296 facilities. This map places 482 of them from primary sources, each with a source record you can open, and every entry names the operator, the county, and the grid operator that serves it. The rest are mostly small regional colocation providers and enterprise buildings that no public register describes. Where are California's data centers? They are listed on this page city by city. By city: Santa Clara (101), San Jose (55), Los Angeles (50), San Diego (30). By county: Santa Clara County (197), Los Angeles County (77), San Diego County (31). Every data center identified in California appears under the city or county it stands in, with its operator and the source that names it. Who operates data centers in California? 148 operators appear in the registers for California. The largest by facility count: Lumen (43), Digital Realty (28), Equinix (27), Cogent (14), Centersquare (14). Interconnection-heavy providers are over-represented because PeeringDB records where networks meet; hyperscalers appear where contributors have mapped their buildings. Does California have a data center moratorium? California has 2 state measures on record: SB 887: CEQA treatment of data centers (proposed, May 2026); SB 886: Data center tariff and ratepayer protection (proposed, Jan 2026). 8 city or county pauses are on record locally. The California Data Center Moratorium Tracker carries each measure with its primary source and a weekly changelog. Which grid operator serves California data centers? CAISO runs the wholesale power market and the high-voltage transmission system for most of California; NON-RTO covers the rest. CAISO covers ~80% of state load; LADWP, BANC/SMUD, and IID are separate non-RTO balancing authorities. Are new data centers being built or delayed in California? 9 named projects in California are delayed, blocked, or under challenge (20 MW disclosed), with 15 local restrictions, 6 jurisdictional actions, 10 utility dockets, and 5 flagged queue row or large-load studys totaling 518 MW. The capital atlas records 8 named sites in California and 6 projects blocked, delayed, or halted ($10.1B disclosed).
