en.Wedoany.com Reported - Brazil's Energy Research Company (EPE) has released the registration results for the country's first national tender dedicated exclusively to battery energy storage: a total of 6,091 projects were registered, with a combined declared capacity of 296.8 gigawatts (GW), setting a new record for submissions in Brazil's electricity auction history. This tender marks Brazil's first national centralized procurement focused on battery energy storage technology, aimed at enhancing the operational flexibility of the National Interconnected System, alleviating transmission pressure caused by the large-scale integration of renewable sources such as wind and solar power, and reducing curtailment rates for wind and solar energy.

The actual procurement volume for this tender is expected to range from 2 to 5 GW. Winning projects will sign 10-year power purchase agreements and begin supplying electricity to the grid starting in August 2028. The declared capacity is nearly 60 times the planned procurement volume, reflecting the willingness of domestic and international industrial capital to participate in Brazil's energy storage market. As of 2024, Brazil's cumulative installed capacity of wind and solar power has exceeded approximately 35 GW. The intermittency and volatility of renewable energy output pose challenges to the safe operation of the grid, and energy storage systems are regarded as key infrastructure for enhancing the grid's capacity to absorb renewable energy.

This tender has attracted companies from across the industry chain, including cell manufacturers, system integrators, and project developers. Sungrow has reached a preliminary agreement with local Brazilian partners for the deployment of commercial and industrial energy storage systems, while DeYE has invested in building an overseas assembly plant in the Manaus Free Trade Zone in Brazil to position capacity for participation in this tender and future market expansion. The currently registered projects remain preliminary expressions of interest; they must undergo technical feasibility analysis, qualification review, and compliance assessment before entering the formal bidding process. Two centralized bidding sessions will be held on December 2 and December 4, 2026, respectively.

Brazil's domestic battery manufacturing industry is pushing the government to introduce localization incentive policies, including setting local manufacturing quotas, which may create certain barriers for imported equipment; the compliance certifications, development of localized operation and maintenance service systems, and coordination of local supply chains required for overseas project implementation also place higher demands on the comprehensive capabilities of participating companies. This tender holds indicative significance for the global energy storage industry chain layout, and its results will shape the initial industrial landscape and competitive dynamics of Brazil's energy storage market.
