The 700 MW initial phase carries an estimated investment value of USD 700 million based on the original capacity target. Battery energy storage systems will provide rapid response capability during demand variations, operational flexibility, and reserve capacity to reduce outage probability and improve service quality. The approach represents a technological shift for Argentina’s power sector, deploying batteries primarily for capacity backup during maximum system stress rather than the voltage and frequency stabilization applications more common in other markets.
Among participating companies are Central Puerto, Coral Energía, Sullair, Aluar, and Edison Energía, which recently established a dedicated battery project division. The Provincial Energy Company of Córdoba launched a separate call for projects up to 100 MW under provincial auspices to participate in the broader AlmaSADI framework.
The tender builds directly on the AlmaGBA precedent, Argentina’s first large-scale storage initiative, which awarded 713 MW of capacity across critical metropolitan Buenos Aires nodes with investment exceeding USD 540 million. Construction work for those installations is currently underway. The technical evaluation process will assess the 235 submitted proposals before economic bid opening proceeds in late June, with final adjudication planned for the first week of July 2026. The procurement’s substantial oversubscription demonstrates private sector confidence in Argentina’s energy infrastructure development policies and regulatory framework for storage assets.
