Three contiguous holdings along the Malheur River, assembled into one generation site.
Eastern Oregon's dry, high-elevation plateau delivers some of the strongest and most consistent solar resource in the Pacific Northwest, with cool ambient temperatures that keep panels efficient.
Natural springs flowing 30 to 40 gallons per minute inside the corridor, a 1.45M gallon internal reservoir, and Malheur River frontage give the project a water and hydro dimension few solar sites can claim.
Direct frontage on US Highway 20 plus a full-length rail-grade roadbed means heavy equipment, modules, and O&M crews move on and off site without new road construction.
The project is structured as a PURPA Qualifying Facility, with the interconnection process underway with Idaho Power and standard-contract pricing frameworks in place.
A 3,000-foot hardened tunnel bored through solid volcanic basalt anchors the corridor: 50,000+ square feet of naturally cooled interior space suited to storage, controls, and secure operations.
Phase 1 runs the Malheur corridor. Phase 2 converts the farm ground to solar and carries the buildout to 80+ MW total, with the existing dwelling and outbuildings retained as project offices and storage.

Preliminary estimates from regional resource data. Final figures follow interconnection studies and detailed design.
Roughly 70,000 single-axis tracked modules along the Phase 1 corridor bench. At an estimated 26% capacity factor, annual output is enough for about 6,700 Oregon homes, delivered under PURPA standard-contract frameworks with Idaho Power as the interconnecting utility and targeted offtaker.
Springs emerge directly from the basalt overhead inside the tunnel at 30 to 40 gallons per minute. With the 25-foot ceiling height, a ceiling-capture drop to a floor turbine can generate silent, continuous power for site loads, independent of sun or wind.
The basalt tunnel holds a stable 55 to 60 degrees year round, a natural thermal envelope for battery energy storage, inverter controls, and secure operations, with the 1.45M gallon internal reservoir available as thermal mass or managed reserve.
Phase 2 converts the 169.56-acre farm site and the north parcel to solar, carrying the project from the corridor-based 32+ MW Phase 1 to a planned 80+ MW total. The farm dwelling and outbuildings are retained as project offices, storage, and the O&M base.

Axiom Grid LLC, a Delaware special purpose vehicle under Kuester-Kamara Investment LLC, holds the project. Acquisition supports a structured build-to-spec framework with seller financing available to qualified principals. Capital formation conversations are active. Interconnection and PURPA offtake are in process with Idaho Power.
