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 investmentUsd.
Power and water
Fully off-grid microgrid system including engine generators and control systems built by Ameresco. 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.
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.
