Genneia Reaches 450 MW Solar Capacity in Mendoza with San Rafael Project Completion

Genneia commissioned the full 180 MW capacity of its San Rafael solar park in Mendoza’s 25 de Mayo district, completing a USD 180 million investment that brings the company’s provincial spending to USD 430 million. The facility spans 500 hectares and deploys 400,000 bifacial solar panels with annual generation capacity exceeding 500,000 MWh, equivalent to powering 135,000 households while avoiding 230,000 tons of carbon dioxide emissions annually. The park’s commercial activation follows initial operation of 140 MW, with the final 30 MW extension scheduled for May 2026.

The project represents Genneia’s third operational solar asset in Mendoza, establishing a combined 450 MW portfolio across the province. CEO Bernardo Andrews emphasized the facility will supply energy to Argentina’s industrial sector with particular focus on mining operations requiring robust decarbonization solutions for global market access. Provincial Energy Minister Jimena Latorre characterized the deployment as evidence of effective public-private coordination advancing Mendoza’s renewable transition to support industrial and mining development with competitive clean energy.

Genneia’s broader expansion trajectory includes completing the 129 MW San Juan Sur project and two 20 MW facilities in Buenos Aires province during 2026, alongside deploying battery storage systems through the ALMA GBA auction that awarded 667 MW of storage capacity across ten developers for USD 540 million. The company’s most significant planned development involves the Mendoza Sur-Diamante solar park with 350 MW initial capacity and potential expansion to 500 MW requiring USD 300 million investment. Management considers structuring this project under Argentina’s Large Investment Incentive Regime (RIGI), though execution depends on resolving transmission infrastructure constraints, specifically the Diamante-Charlone extra-high voltage line.

Mendoza province deploys provincial funds to accelerate transmission buildout, recently opening bids for the Valle de Uco 220/132 kV transformer station and Capiz station expansion with associated 132 kV lines. The province’s total operational solar capacity reached 774.4 MW with projections to exceed 1,000 MW by 2030. During construction, San Rafael employed over 300 workers at peak activity, while the earlier Anchoris park in Luján de Cuyo generated 350 positions during its USD 160 million buildout that added 180 MW with 360,000 bifacial modules.
