Deal Analysis

Central Puerto secured authorization for its 140 MW Parque Solar Fotovoltaico Hunuc I in San Juan, Argentina, to enter the Wholesale Electricity Market. This development, announced for 2026-03-09, positions a substantial solar asset for future revenue generation within Argentina's power system. The project's integration into the National Interconnected System (SADI) will occur through a new transformer, ensuring grid stability for the 140 MW capacity. This authorization provides Central Puerto with a clear path for commercial operation of the Hunuc I solar park, a key step in monetizing the renewable energy investment in San Juan. The move by Central Puerto demonstrates a commitment to expanding its generation portfolio with renewable assets in Argentina. Argentina's Secretaría de Energía provided the crucial authorization for the 140 MW Hunuc I solar park's market entry. CAMMESA, the Buenos Aires-based market administrator, will subsequently coordinate the operation of the Parque Solar Fotovoltaico Hunuc I within Argentina's National Interconnected System (SIN). This authorization facilitates CAMMESA's role in managing transactions for the 140 MW solar capacity within the Wholesale Electricity Market. Distrocuyo S.A., an Argentine electricity distribution utility operating in Mendoza and part of Grupo Energía San Juan, maintains a regional presence near the San Juan project location. The addition of 140 MW of solar capacity from the Hunuc I park will influence Argentina's Wholesale Electricity Market dynamics, diversifying the country's generation matrix.

KEY DETAILS

The project will connect to the Sistema Argentino de Interconexión (SADI) via a new transformer station. It has potential for expansion up to 380 MW. The plant will be developed on approximately 690 hectares. The environmental file for the project is under evaluation by the Provincial Directorate of Environmental Assessment and Impact. The project's location is linked to the growing electricity demand from mining activity in San Juan. Quote: "se conectará al Sistema Argentino de Interconexión (SADI)", "contempla una expansión futura de hasta 380 MW", "La planta fotovoltaica se desarrollará sobre una superficie cercana a 690 hectáreas", "El expediente ambiental del proyecto se encuentra en evaluación ante la Dirección de Evaluación e Impacto Ambiental de la provincia, que convocó a una audiencia pública para analizar sus aspectos técnicos y ambientales.", "La ubicación del proyecto Hunuc I también se vincula con el crecimiento de la demanda eléctrica asociada a la actividad minera en San Juan, especialmente a emprendimientos de cobre en desarrollo en la región."
