On March 2nd, 2026, the Secretary of Energy published Resolution 50/2026 (“Resolution 50” ), initiating the national and international open tender for “Abastecimiento de Energía Eléctrica por Centrales de Almacenamiento para reserva y confiabilidad en el MEM (AlmaSADI)” (the “Call for Bids”).
This Call for Bids is intended to procure energy storage services through the execution of power storage agreements to increase operating reserves in the short term in the Wholesale Electricity Market (“WEM”), with CAMMESA (for the Spanish acronym of Compañía Administradora del Mercado Mayorista Eléctrico S.A.) as the off-taker.
The procurement targets the following regions: BAS, Central Region, La Pampa, Litoral, NEA, NOA, and Cuyo. The intended aggregate storage capacity is 700 MW, with the objective of improving system reliability and ensuring short and long-term adequacy of supply for the WEM in an efficient manner.
In this regard, this tender follows the “AlmaGBA” call for bids, under which storage generation facilities for the Greater Buenos Aires area were awarded for a total of 713 MW (see our comments here).
