The announcement was made in Resolution 906/2023, published on Monday 6 November.

Technical information about the electricity grid in Argentina and a procedure for receiving and evaluating the EOIs will now be prepared by the country’s wholesale electricity market operator, CAMMESA (Compañía Administradora del Mercado Mayorista Eléctrico Sociedad Anónima).

CAMMESA needs to publish its procedure within 20 days of the Resolution’s publication and interested parties will have 120 days to submit their proposals, with CAMMESA then having 60 days to present the evaluations of those proposals to the Ministry.

Interested parties are being invited to propose projects encompassing the financing, construction and management of energy storage systems in the wholesale electricity market. The projects could be for optimising generation dispatch, providing power reserve services or other mechanisms proposed.

Different technologies and technical characteristics will be considered, with proposals expected to outline power and energy, charging and discharging periods, maximum storage periods (in days to years), useful life and number of cycles, degradation and other details.

With Argentina being a major source of lithium carbonate for lithium-ion batteries, EOIs which propose ways to integrate a national supply chain into project delivery will be “valued”, the Resolution added.

The news comes after our publisher Solar Media recently held the Energy Storage Summit Latin America 2023 in Santiago, Chile, where the bulk of the sub-continent’s grid-scale energy storage activity is happening.
