en.Wedoany.com Reported - China's Windey Energy has announced an investment of 100 million Brazilian reais to build its first battery energy storage system (BESS) factory in Brazil, located in Camaçari, Bahia, with an expected annual production capacity of 1.5 GWh.
The company plans to start local production in the first half of 2027. This move aims to meet the localization requirements for certain tenders and expand the pool of suppliers eligible to bid for power supply contracts in August 2028. The announcement comes as Brazil's Ministry of Mines and Energy (MME) prepares for the country's first energy storage auction and seeks to strengthen the related domestic industrial chain. The government, in partnership with the Brazilian Development Bank (BNDES), is assessing whether there are enough qualified suppliers to meet localization requirements without undermining the auction's competitiveness.
The new factory will be located in the Camaçari industrial zone. Windey Energy stated that existing facilities are ready and only require appropriate modifications to install equipment for the assembly, integration, testing, and commissioning of energy storage systems. The company's strategy includes obtaining Computerized Supplier Certification (CFI), through which BNDES includes products in the Finame code system, granting access to favorable financing conditions. Obtaining this certification is considered one of the main prerequisites for participating in bids for domestically produced equipment.
This investment reinforces a trend advocated by manufacturers already established in Brazil. While the government was drafting auction rules, companies such as WEG, Moura, and UCB submitted comments arguing that procuring locally produced systems could stimulate industrial investment, expand capacity, and consolidate the domestic energy storage supply chain. The government's concern, however, is to avoid localization requirements excessively limiting the number of participants. MME Executive Secretary Gustavo Ataíde previously asked BNDES whether Brazilian industry could supply Finame-compliant equipment within the stipulated timeframe.
According to Windey Energy, this factory represents the second phase of its expansion in Brazil. In 2025, the company established a national office in Salvador and set up a research and development center in partnership with Senai Cimatec. Upon entering the manufacturing phase, the initial investment in the first year of production is estimated at approximately 30 million Brazilian reais. Windey Energy stated that its operations in Brazil will not only serve the capacity reserve auction but also meet future energy storage demands driven by renewable energy expansion, transmission and distribution systems, and industrial users. The company also believes that this investment could position Brazil as a regional hub for energy storage technology in Latin America, integrating local production, domestic financing, and international technology.
