NEW YORK, May 26, 2026 /PRNewswire/ — DESRI, a leading renewable energy company, and Tierra Adentro Growth Capital (TAGC), an investment platform providing strategic capital for next generation infrastructure, today announced the start of construction on two co-located solar and storage projects in San Juan County, New Mexico.
Foxtail Flats Solar and Storage (Foxtail Flats) comprise a 170 megawatt (MW) solar project paired with an 80 MW/320 megawatt hour (MWh) battery storage facility contracted under a long-term power purchase agreement with the Incorporated County of Los Alamos. Four Mile Mesa Solar and Storage (Four Mile Mesa) comprise a 100 MW solar project paired with 100MW/400 MWh battery storage project procured through PNM’s Rate 36B to support Meta’s data center operations. Project stakeholders celebrated the groundbreaking for both facilities on May 14, 2026.
Together, the projects represent 270 MW of solar energy and 180 MW of battery energy storage, sited on land owned by the Ute Mountain Ute, and adjacent to DESRI’s operating San Juan Solar and Storage facility as well as the retired San Juan Generating Station. The projects are expected to begin commercial operations in 2027.
“Breaking ground on Foxtail Flats and Four Mile Mesa marks another significant milestone for DESRI and for San Juan County,” said Thomas de Swardt, President of DESRI. “These projects build on the success of our adjacent San Juan Solar and Storage facility and reflect DESRI’s commitment to the region’s clean energy transition. We are grateful for the continued partnership with the Ute Mountain Ute Tribe, the Incorporated County of Los Alamos, PNM, and Meta, and look forward to delivering reliable, cost-effective renewable energy to New Mexico. Finally, DESRI is also thrilled to partner with TAGC in their equity investment in the Projects and looks forward to growing a broader partnership with them.”
“The Foxtail Flats and Four Mile Mesa projects will be a milestone in New Mexico’s energy transition and economic development,” said Alok Sindher, Managing Partner at TAGC. “Together, these projects will employ approximately 600 construction personnel at their peak and add energy and capacity to the local grid. We’re excited that this equity investment will catalyze local economic growth and employment and is a significant step forward in New Mexico’s progress towards a cleaner grid. We look forward to continuing to partner with DESRI, the Ute Mountain Ute Tribe, the Incorporated County of Los Alamos, PNM, and other stakeholders to advance clean energy in New Mexico.”
“Foxtail Flats’ combination of solar plus storage means we can capture abundant New Mexico sunshine during the day and then use the batteries to deliver that energy in the evening, when people are home, lights are on, and the grid is under the most stress,” said Matt Heavner, Vice Chair of the Incorporated County of Los Alamos Board of Public Utilities. “It will provide a major new source of reliable, carbon-free electricity to Los Alamos, Los Alamos National Laboratory, Sandia National Laboratory and Kirtland Air Force Base. The Los Alamos community has been awaiting Foxtail Flats, and it is exciting to put shovels in the ground on a project of this scale.”
Financing for the construction of the projects was led by Norddeutsche Landesbank Girozentrale (NORD/LB) and Santander Corporate & Investment Bank (Santander).
SOLV Energy will serve as the engineering, procurement, and construction (EPC) contractor for the solar and storage facilities.
