São Paulo,, August 28, 2025 / Prnewswire / – CATL, a world leader in innovative energy storage solutions, unveiled its latest technologies during its beginnings at the Smarter E South America 2025, the largest energy storage exhibition on the continent. Tenner Stack – Currently the leading energy storage system with ultra -large capacity to the world, 9MWh – is adaptable to different cellular technologies of CATL, offering up to five years of zero degradation or high temperature resistance. It is suitable for South America Varied climates, highlighting CATL’s commitment to the sustainable energy development throughout the region.
“”Brazil has one of the most diverse applications of energy storage systems in the world. With our history proven in the supply of product solutions for a diversified range of decarbonization applications and the strong local partnerships that we feel, we are committed to helping to accelerate the region’s transition to clean energy, “said Ray SeeExecutive president, Americas Energy Storage Business Division.
Adapted to Brazil demanding conditions
Brazil The energy market is at a tilting point, ready for rapid growth due to a grid dominated by renewable energies, creating a demand for flexibility solutions. Bloombergnef underlines this storage in Brazil is “ready to take off”, as by 2050, Brazil more requires 6 dollars In energy investment to reach Net Zero, highlighting its explosive potential.
In response to rapidly growing demand in this region, CATL introduces TEner Stack, a revolutionary product that represents a strategic jump forward, in flexibility of deployment, in safety and transportability.
The system stores 9MWh of energy, which can fully load 45 electric buses with 200 kWh batteries or provide 6 years of electricity for an average Brazilian household. It uses the land zone 45% more efficiently and offers an energy density projected 50% higher than conventional 20 -foot systems. For major projects, it needs 45% less containers to build a station of 800mWh than 5mWh systems.
Flexibility is integrated. The “two in one” design weighs less than 36 tonnes, which maintains it in transport regulations in 99% of world markets. Its compatibility with standard shipping methods reduces transport costs up to 35%, while a lower gravity center guarantees stability on routes with bridges, tunnels and rural infrastructure constraints.
Safety and reliability are integrated into the Téner battery. It uses LFP battery chemistry for thermal stability and improved gas sensors which are 40% more sensitive, triggering a suppression of the fire 35% faster. The three -layer insulation offers up to two hours of fire resistance. The system also meets the seismic standards of the IEEE693, or otherwise included as having a magnitude of category 9 earthquakes and category 5 hurricanes. Its aircraft thermal management maintains noise at only 65 dB (A), which makes it suitable for use in cities.
The Brazilian and other South America The markets also have unique challenges: frequent network fluctuations, high ambient temperatures and limited maintenance resources in remote facilities. Tener Stack is specifically designed for these various conditions.
Its new gas sensors offer a maintenance -free lifespan over 10 years, compared to traditional sensors at 2 years, reducing operational interruptions in difficult to access sites. Meanwhile, the rebuilded container system offers a self-faded design that eliminates short-term or 8-year-old leading dependence, extending backup for BMs and anti-explosion fans from 20 minutes to 2 hours during breakdowns.
With other offers such as the Enerone + and Tener series, CATL offers a larger range of options for out -of -network, commercial and on -the -market energy projects. Designed to be light, highly portable and equipped with an integrated humidity reduction system, these solutions are designed to withstand the wet conditions of tropical forests and operate reliably through extreme temperatures of -35 ° C to 55 ° C. CATL provides personalized energy solutions for projects of all scales through Brazil And South America.
Engaged South America Sustainable future
Catl has already made its mark BrazilFueling the first storage project on the scale of the country’s public services, the Energy Storage Project register in 2022. After three years of stable operation, it has become a reference for the energy storage industry in South America. The site has reached an important step this year by expanding the first power plant, marking a new growth phase for CATL on the local market.
Beyond BrazilCATL has continually deepened its global business provision, accelerated the expansion of industry and continuously improves its basic competitiveness throughout South America. The company actively constitutes local teams in Chile,, Argentina,, Mexico,, Colombiaand the Dominican Republic.
In September, a new South America The office will open Chileoffering local expertise and customer innovation support. With the TEner series and other advanced energy storage products, CATL continues to push the limits and strengthen its commitment to help South American and global partners to accelerate the energy transition by providing more flexible, safe and lasting solutions.
At the end of H1 2025, CATL ESS products were deployed in more than 2,000 projects around the world, covering all climatic zones and operating environments. CATL also ranked first in the market share of global energy storage battery shipments for four consecutive years in 2024, deployment of more than 93GWh.
