Overview
- DESRI and equity partner Tierra Adentro Growth Capital have started construction on Foxtail Flats and Four Mile Mesa, two adjacent projects in San Juan County that together will deliver 270 MW of solar and 180 MW / 720 MWh of battery storage.
- Foxtail Flats pairs 170 MW of solar with an 80 MW / 320 MWh battery under a long‑term power purchase agreement with the Incorporated County of Los Alamos, while Four Mile Mesa pairs 100 MW of solar with a 100 MW / 400 MWh battery procured through PNM’s Rate 36B to support Meta’s data center.
- Both projects sit on Ute Mountain Ute Tribe land next to DESRI’s operating San Juan Solar and Storage facility and the retired San Juan Generating Station, and are expected to begin commercial operations in 2027.
- SOLV Energy is the engineering, procurement and construction contractor, construction financing is led by NORD/LB and Santander, and TAGC has joined as an equity partner; detailed financing terms were not disclosed.
- Developers say peak construction will employ about 600 workers and that the projects aim to provide reliable, dispatchable clean power for local communities, national labs, and data centers as part of the region’s transition from coal.
