Opposition and litigation at this site

Yes. CyrusOne AI Data Center at NAS Lemoore in Kings County, California is contested. Hearings, public comment, petitions, or organized opposition are on record, and no lawsuit has been filed so far. Kings County Supervisor Garrett Gilcrease (also Farm Bureau president) opposed the project on water grounds during his 2024 campaign; the project advanced with little public input; no formal legal challenge as of mid-2026.

How the community has taken it

Reception is a sourced signal, not an editorial judgment: contested means active public debate is on record, with hearings, petitions, or organized opposition, without litigation.

Kings County Supervisor Garrett Gilcrease (also Farm Bureau president) opposed the project on water grounds during his 2024 campaign; the project advanced with little public input; no formal legal challenge as of mid-2026. A 2023 EIR projects ~400 construction workers and ~20 permanent employees for the proposed facility (projections, not confirmed headcount). The ~$1B figure reported by the Hanford Sentinel covers the integrated project (data center + ~425 MW solar + battery storage), not the data center alone, so no data-center-only investment figure is recorded.

Power and water

Data Center Dynamics describes the project as off-grid, colocated with a dedicated on-site microgrid that includes engine generators and control systems built by Ameresco. As of October 2026 no cited source names a utility supplier for the data center. Aligned with Trump Administration AI Action Plan. Separate discussions ongoing for 425MW solar farm on 920 acres of surrounding DOD land.

Developer has not disclosed cooling method or water source (arid Central Valley; NAS Lemoore draws from the Kings River). Kings County Supervisor Gilcrease flagged water as a key opposition concern.

Notes on the record

Located at Naval Air Station Lemoore on the Kings/Fresno county border. Ameresco leads energy infrastructure via its Intelliscale platform; CyrusOne operates the data center for federal and defense AI workloads (FedRAMP, FISMA High, DoD IL5/IL6). Land leased from DOD. Announced September 9, 2025; first phase expected online 2027. Coordinates approximate.

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

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.

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.
