CATL Announces Local Partnership, Showcases Full-Chain Storage at The Smarter E South America 2026

SÃO PAULO, Aug. 29, 2026 /PRNewswire/ -- CATL is showcasing its full energy storage ecosystem at The Smarter E South America 2026 in São Paulo from August 25 to 27, demonstrating capabilities across the entire value chain, from cell R&D and energy management to project delivery and localized services. At the show, the company also announces a strategic partnership with Moura to jointly participate in Brazil's Capacity Reserve Auction for Energy Storage, reinforcing its commitment to the country's resilient and sustainable energy future.

A Storage Portfolio Engineered for Brazil's Energy Landscape

CATL is presenting a broad portfolio of large-scale storage solutions purpose-built to meet Brazil's evolving power market needs.

TENER S, CATL's next-generation energy storage solution, leads the lineup. Built to maximize long-term asset value, it delivers zero degradation in capacity and power over the first year of a 20-year design life. Its liquid cooling system cuts auxiliary power consumption by up to 20%, lowering operating costs. TENER S also increases areal energy density by 30% and reduces site footprint by 20%, lowering balance-of-system costs. For Brazil, where grid instability remains a persistent challenge, TENER S delivers the utility-scale capacity and long-term reliability the country needs for renewable integration. The system has already been selected for major global projects, including a 1.5 GWh project in Spain and a long-term service-backed deployment at the Supernode project in Australia.

For high-density utility and industrial/commercial applications, TENER H leverages 575 Ah cells to pack 9,008 kWh per container, boosting land utilization by 45% and cutting project costs where land is at a premium. It supports flexible 2-, 4-, and 8-hour configurations: the 2-hour option delivers fast response for grid stabilization, while the 4- and 8-hour versions achieve up to 96.0% round-trip efficiency to maximize long-duration returns.

CATL is also unveiling TENER Sodium in Brazil for the first time. Launched recently, this 30 MWh integrated sodium-ion system delivers a 20-year design life, 95% round-trip efficiency, stable operation from -20°C to +45°C, and IEC/UL/CE certifications. Beyond its advanced cells, the system features coordinated BMS, PCS, and thermal management optimized for sodium battery characteristics, enabling rapid deployment and site-level reliability.

TENER Sodium extends CATL's site-level engineering and full-lifecycle asset management capabilities into the sodium-ion domain—capabilities built through years of turnkey project deliveries worldwide and reinforced by the company's recently unveiled whole-station testing facility in Xiamen, which validates real-world grid-connected performance to ensure bankable results from day one. Together, these strengths underscore CATL's role as a leading comprehensive energy storage solution provider.

Rooted in Brazil, Partnering for the Long Run

"CATL's commitment to Brazil rests on three fundamental pillars: partnership, proven delivery, and localized service," said Ray See, Executive President of CATL's Americas Energy Storage Business Division. "While we provide world-class storage solutions, our broader mission is to build self-sustaining capabilities on the ground. By forging deep local alliances, executing with proven excellence, and equipping domestic talent with the expertise to take the lead, we establish a reliable support ecosystem that stands with our partners for the long run."

At the event, CATL announces a strategic partnership with Moura, a leading Brazilian battery manufacturer, for joint participation in Brazil's Capacity Reserve Auction for Energy Storage (LRCAP 2026 – National Storage) promoted by the Ministry of Mines and Energy. This collaboration combines CATL's advanced energy storage solutions with Moura's deep local expertise, with the support of a second strategic partner that holds the No. 1 market share in PCS/inverters in the country, aiming for localized production that complies with the auction's local content requirements.

The partnership builds on CATL's strong and growing foothold in Brazil, where the company already holds a 45% market share in energy storage. Its project portfolio spans utility transmission, agriculture, cold-chain logistics, and industrial facilities, including the landmark Registro project. As Brazil's first utility-scale battery energy storage system in the transmission sector, Registro has reliably supported a critical substation serving 15 cities and some 2 million residents since its commissioning in December 2022.

CATL's local commitment extends across the full lifecycle of its storage assets. Its South American service network includes five senior storage experts and more than 140 certified engineers, enabling a tiered response framework: one-hour remote support, two-day on-site dispatch, and five-day cross-regional expert escalation. Dedicated regional inventory, backed by four global core warehouses and over 50 front-end stocking points, guarantees core spare parts availability for up to 20 years. CATL also offers standardized training through its South American facility in Santiago, Chile, and operates regional recycling channels for compliant transport, dismantling, and material recovery at end of life.

Bringing Global Excellence and Recognized Bankability to Brazil

CATL's industry leadership has recently been underscored by three of the world's most influential energy sector evaluators. S&P Global Energy named CATL a Tier 1 supplier in both energy storage battery cells and systems for 2026, ranking it first globally by market share in each category. Wood Mackenzie awarded CATL an "A" grade and placed it among the top 3 in its inaugural Global BESS Integrator Comprehensive Ranking. BloombergNEF has included CATL on its Tier 1 Energy Storage List for 11 consecutive quarters since the ranking's inception in Q1 2024. Together, these endorsements validate CATL's comprehensive strengths in long-term reliability, stable delivery, and bankability across global markets.

This industry recognition is backed by strong financial and shipment performance. CATL's energy storage battery system revenue reached RMB 53.26 billion (approximately $7.9 billion) in the first half of 2026, up 87.54% year on year. According to SNE Research, the company shipped 125.0 GWh of ESS batteries in the period, capturing the world's largest market share.

Recent project successes further demonstrate CATL's full-lifecycle delivery capability. In May 2026, CATL and Solarpro brought online a 602 MWh project in Burgas, Bulgaria, now Eastern Europe's largest operational battery storage facility. In Australia, the Supernode project reached Stage 2 commercial operation in August 2026, while Stage 3 secured A$469 million in debt financing; CATL is supplying systems across all stages and providing long-term O&M support. In the United States, the 380 MW / 1,416 MWh Gemini solar-plus-storage project has been operational since July 2024 and completed US$760 million in refinancing in March 2026, a clear sign of investor confidence in CATL-equipped assets.
