Argentina’s solar pipeline advances with 143 MW in transmission access requests across six provinces

Argentina’s National Electricity and Gas Regulatory Entity publicized transmission capacity access requests for solar projects totaling 143 MW between March and June 2026, with installations planned across San Juan, Corrientes, Chaco, La Rioja, Santa Fe, Buenos Aires, Catamarca, and San Luis provinces. The projects follow regulatory procedures established by ENREGE requiring five business days for public disclosure on both ENREGE and CAMMESA websites, followed by an additional five business days for submission of alternative access projects, objections, or observations from third parties. If no opposition emerges, regulators proceed with authorization.

The largest individual projects include the 24 MW Aluar Abasto plant by Aluar Aluminio Argentino in Buenos Aires province’s La Plata district, connecting to 33 kV bars at Kaiser Substation under EDELAP’s concession. Coral Consultoría en Energía submitted two applications: the 20 MW Santa Catalina I facility in Corrientes’ Capital department, connecting to Distribution Center No. 28 at 33 kV, and the 20 MW Ceres I plant in Santa Fe’s San Cristóbal department, linking to Ceres Transformer Station at 33 kV under EPESF jurisdiction. Both received separate authorizations by early June following earlier request periods.

PV La Perla advanced two Chaco province projects through the transmission access process in April after securing March authorization as wholesale market generating agents. The Quitilipi project of 15 MW and Tres Isletas plant of 20 MW both connect through Secheep’s distribution network, which serves as Additional Provider of Technical Transport Function. Industrias Juan F. Secco obtained transmission authorization for the 7 MW Bella Vista plant in Corrientes, connecting at 33 kV to the Bella Vista-Desmochado medium voltage line, while subsequently requesting access for the 20 MW Esquina facility in the same province.

San Juan province saw two applications: Coral Consultoría en Energía’s 5 MW San Pedro I project in Calingasta department connecting to the 33 kV Calingasta-Mina Casposo line under Naturgy jurisdiction, and TECSOL’s 8.87 MW San Luis Oeste facility in Juan Martín de Pueyrredón department linking to EDESAL’s CT23 feeder. Additional projects include the 10 MW Chamical Solar II in La Rioja connecting to EDELAR’s network and the 6 MW Arcor Recreo I in Catamarca linking to EC SAPEM’s 33 kV installations.
