- CAISO
- Interconnection
- Water
- Quantum processors are cooled in dilution refrigerators (cryostats) to roughly 10 millikelvin using helium-3/helium-4 mixtures, not chilled water. Only ancillary building HVAC would draw municipal water; no facility-scale process-water use has been disclosed.
The California (CAISO) grid demand right now: 42.6 GW (EIA-930, 2026-08-25 23:00).
County water status: No drought in Santa Barbara County, week of 2026-08-18 (US Drought Monitor). Data centers are large water users for cooling; this is the neutral local water picture.
Why here
Google Quantum AI Campus Santa Barbara sits on owned in Goleta, California, USA. It connects to the CAISO grid, draws on grid power. This siting summary is composed from the record's held fields, not speculation; see methodology.
