Argentina’s government has received 232 qualified bids from 37 national and international companies, totalling 8.2 GW for its AlmaSADI battery storage tender (Argentinean government press release 24/06/2026). The bids represent nearly 12 times the target capacity, with projects located across the NOA, NEA, Centro, Litoral, Cuyo, Pampa and Buenos Aires regions, excluding the Buenos Aires Metropolitan Area. The largest volumes offered were in Buenos Aires (42 projects, almost 2 GW), NEA Chaco and Formosa (62 projects, 1.8 GW) and NOA (37 projects, 1.4 GW).
Launched in March 2026, the Alma SADI tender aims to award around 700 MW of battery energy storage capacity with at least four hours of availability across critical nodes of the Argentine Interconnection System (SADI). The government expects to award around USD700mn in projects in early July, following final evaluation by CAMMESA.
The tender forms part of a broader plan launched in 2024 to ease pressure on the electricity system, reduce outages and improve service quality after two decades of insufficient investment to match demand growth. A similar tender, the AlmaGBA, had awarded in September 2025 ten BESS projects (713 MW) within the AMBA.
