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.
