The Argentine company Aluar has been awarded a contract to develop a battery energy storage system (BESS) in the city of Goya, Corrientes province. The installation will have a capacity of 50 MW and a storage capacity of 250 MWh.
The investment to date, between the new BESS project and the previous one awarded in San Fernando, totals 50 million dollars.

The initiative is being developed within the framework of the AlmaSADI tender, called by Resolution SE No. 50/2026, whose objective is to rebuild the reserves of the Argentine Interconnection System (SADI), reduce the risk of supply interruptions, guarantee supply during periods of high demand and contribute to the stability of the electrical grid.
The installation will be connected to the 33 kV Bus B (3GOYB) of ET Goya, belonging to TRANSNEA, where it will evacuate the stored energy to the distribution network for a maximum of 5 hours of capacity, in accordance with the Terms and Conditions of the AlmaSADI tender and current regulations.
The main contribution of the system at this node will be the structural tension support on the 132 kV busbar. According to the TRANSNEA Reference Guide, this condition is of particular importance because the Goya Transformer Station is located at a line end.
The awarding of this project reaffirms Aluar's commitment to the country's energy development, promoting technological solutions that strengthen the security of the electricity supply.
