This is a source-attributed discovery row. It can help you find a place and its citations; it is not a DataCenterData finding that the facility is distinct or currently operating.

Provider notes
Energy. 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.
Water. 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. 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.
What the source record says
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.
Any MW value is reproduced as source-reported context. Its measurement boundary is not established consistently enough for comparison. Unknown is not zero.

Compute Atlas 1.34.1 with retained prior rows and publication holds. This is a DataCenterData composite, not an unmodified publisher edition. This row uses the captured source from 1.34.1, source as of 2026-10-14T20:40:52.293Z.
That does not mean the row is wrong, and it does not mean no reviewed record exists for the same place. A link is added only when an identifier or source establishes the match.
