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.

Community sentiment

Contested

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.

Gilcrease calls for dialogue over data center
