Opposition and litigation at this site
Nothing on record as of July 6, 2026. No lawsuit, organized opposition, or contested hearing over ECL CSC-1 FlexGrid AI Data Center in Santa Clara, Santa Clara County, California appears in the sources this registry tracks. That is an absence in our sources rather than a finding that none exists, and local opposition often predates any coverage a national dataset would pick up.
If you live near this site and something is happening that this page does not show, that is worth telling us. Send us the document and it goes in the record with the source attached. For sites where opposition is already established, see every contested site we track.
Power and water
FlexGrid architecture combines SVP on-grid electricity with natural gas and hydrogen fuel cells behind the meter, bypassing SVP grid interconnection queue constraints. Sub-1.15 PUE target. Rack densities 75-270kW for AI high-density compute.
When hydrogen fuel cells are used, by-product water from hydrogen generation supplies the cooling loop, eliminating freshwater draw, significant for drought-prone California.
Notes on the record
Exact street address not publicly disclosed. Coordinates are Santa Clara city centroid (approximate). Announced April 21, 2026. First phase targets Q4 2026 delivery. ECL CEO Yuval Bachar stated the project addresses SVP grid capacity constraints that have forced other data center developers into multi-year interconnection queues. Project targets AI training and inference workloads.
What the record does not establish, and the document that would
In every fight on our tracker the decisive fact came out of a public records request. These are the requests for this site.
- Tax abatements or other public subsidy
- Permanent jobs promised
- Land area
- How the community has received it
Which document closes each gap
- Tax abatements or other public subsidy
- The abatement, PILOT, or development agreement approved by the county, city, or development authority, and the state's data center sales tax exemption certificate if one was issued.
- Permanent jobs promised
- The economic development application or incentive agreement, which usually states a job commitment and a clawback.
- Land area
- The rezoning application, the plat, or the deed recorded with the county.
- How the community has received it
- Planning commission and governing body minutes, public comment records, and any petition or lawsuit filed in the county.
Have one of these documents? Send it to us and we will add it to the record with attribution.

Distances are between recorded coordinates, many of which are a city or county centroid, so treat them as approximate. Cumulative load on one utility and one aquifer is the question a planning commission rarely asks.
