On August 29, CATL issued an official PR Newswire release announcing that at the Smarter E South America 2026 (August 25-27, 2026) in São Paulo, Brazil, the company for the first time unveiled in Brazil its 30MWh integrated TENER Sodium sodium-ion battery energy storage system, and formed a strategic partnership with leading Brazilian battery manufacturer Moura to jointly participate in Brazil's Capacity Reserve Auction for Energy Storage (LRCAP 2026 – National Storage) promoted by the Ministry of Mines and Energy. The TENER Sodium system is CATL's first dedicated sodium-ion energy storage platform, and its Brazil debut delivers 30MWh capacity, 20-year design life, 95% round-trip efficiency, stable operation from -20°C to +45°C, and IEC/UL/CE certifications, with coordinated BMS/PCS/thermal management optimized for sodium battery characteristics.
The release also disclosed that the CATL-Moura strategic partnership is designed to meet the local content requirements of the LRCAP 2026 auction: the two parties will combine CATL's expertise in cell and system integration with Moura's local manufacturing and channel resources in Brazil, together with a third partner that holds the No. 1 market share in PCS/inverters in Brazil, to jointly advance local production capacity to comply with the auction's local content rules.
CATL currently holds a 45% market share in Brazil's energy storage market, with a project portfolio spanning utility transmission, agriculture, cold-chain logistics and industrial facilities, including the Registro project commissioned in December 2022 - Brazil's first utility-scale battery energy storage system in the transmission sector, reliably supporting a critical substation serving 15 cities and some 2 million residents. CATL's storage systems are also serving benchmark overseas projects including the 602MWh Burgas project in Bulgaria (grid-connected May 2026, Eastern Europe's largest), a 1.5GWh project in Spain, and the Supernode project in Australia (Stage 2 commercial operation August 2026, Stage 3 A$469 million debt financing).
