Source-reported capacity; not metered consumption. Review underlying documents and notes. Planned capacity may include future phases and is not added to operational capacity here. The source may use facility, grid-feed or IT capacity definitions; consult the linked documents.
Coordinate precision is a source label, not an independent parcel survey. A marker does not confirm utility territory or establish an effect on residential bills.
Reported lifecycle history
- Proposed
BLM's Four Rivers Field Office received Rhea Data's application for a large-scale data center campus in August 2025. Rhea supplied more information in spring 2026, and BLM plans to publish a notice of intent in the Federal Register before the end of 2026. That notice opens NEPA review and public comment.

Source notes
Proposed 4-million-sq-ft, multi-building campus on BLM-managed public land in southern Ada County, near Blacks Creek Reservoir on Kuna-Mora Road and east of Meta's Kuna data center. Transmission and electrical rights-of-way extend into Elmore County. Acreage differs by outlet: 3,226 acres (BLM spokesperson, the figure recorded here); a ~3,200-acre campus plus ~550 acres of rights-of-way (3,750 total); or ~3,700 acres. The 600 MW data-processing figure comes from a hedged statement by BLM Field Manager Jared Blades ('I think that has a 600-megawatt data processing capacity'), repeated by KIFI. Treat it as preliminary. The pin is the OpenStreetMap feature for Blacks Creek Reservoir, the landmark the sources name. It is not a parcel location; no parcel or legal description has been published. This is a different project from rPlus Energies' Blacks Creek Energy Center solar plant south of the Boise airport. Rhea Data had not responded to media requests when these articles were published.
The preliminary design includes an on-site natural-gas power plant and electrical connection facilities to Idaho Power. BLM Four Rivers Field Manager Jared Blades told KTVB the plant could produce 'about 450 megawatts'. Other outlets say BLM was still holding back the power figure while the design takes shape, so treat both MW figures as preliminary. East Idaho News says the campus is linked to Arevia Power's proposed 400 MW Snake River Energy solar project on BLM land north of Twin Falls.
