An 1880s ranch, now an off-grid microgrid and research site.
A historic ranch on a system that couldn't keep up.
Horseshoe Ranch was established in the 1880s and now sits inside the 71,000-acre Agua Fria National Monument, protected under Arizona Game and Fish ownership since 2011. It ran on generators for decades, then on an off-grid system built by a contractor without off-grid depth — and it never met expectations.
A full reconstruction, built to grow.
NewGrid supported and stretched the old system until demand outgrew it, then rebuilt the plant: a reconstructed equipment shed, new power conversion, a lithium battery bank, and triple the solar capacity. The latest major upgrade brought the site to 40 kW of solar, 204 kWh of Pytes lithium storage, and 30 kW of Sol-Ark inverters.
- 40 kW solar
- 204 kWh Pytes V5 lithium iron phosphate battery
- 30 kW Sol-Ark inverters
- 60 kW diesel generator
- 120/240V split phase
Powering ranch life and university research.
The ranch now hosts Arizona State University's agricultural research alongside a working headquarters — air-conditioned bunkhouses, pool, and hot tub included — all carried by the microgrid.
