CATL brought a broad range of utility-scale storage systems to São Paulo, each aimed at specific pain points in Brazil's electricity market.
Headlining the booth is TENER S, the company's latest storage solution with a 20-year design life and zero degradation in capacity and power during the first year of operation. Its integrated liquid cooling system cuts auxiliary power consumption by up to 20%, helping lower ongoing operating costs. The system also boosts areal energy density by 30% while shrinking site footprint by 20%, reducing balance-of-system costs. That's a meaningful advantage in a market where grid instability keeps complicating renewable integration. TENER S has already been picked for major international projects, including a 1.5 GWh installation in Spain and the Supernode development in Australia.
For high-density utility and industrial applications, CATL is featuring TENER H, which uses 575 Ah cells to pack 9,008 kWh into a single container. That configuration improves land utilization by 45%, a real cost advantage where real estate is expensive. The system supports flexible 2-, 4-, and 8-hour configurations. The 2-hour variant targets fast-response grid stabilization, while the longer-duration options achieve up to 96.0% round-trip efficiency for extended discharge cycles.
Also making its Brazilian debut is TENER Sodium, a 30 MWh integrated sodium-ion system CATL launched globally just recently. It comes with a 20-year design life, 95% round-trip efficiency, stable operation from -20°C to +45°C, and IEC/UL/CE certifications. The system integrates battery management, power conversion, and thermal management subsystems optimized for sodium-ion chemistry, enabling faster site deployment and improved field reliability. It's backed by CATL's newly commissioned whole-station testing facility in Xiamen, which validates grid-connected performance under real-world conditions.
"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."
That message landed with the Moura partnership announcement. The collaboration combines CATL's advanced storage solutions with Moura's local manufacturing and market knowledge, supported by a second strategic partner holding the largest PCS/inverter market share in Brazil. The alliance is structured to enable localized production that meets the auction's domestic content requirements.
CATL already holds a 45% market share in Brazil's energy storage sector, with projects spanning utility transmission, agriculture, cold-chain logistics, and industrial facilities. The landmark Registro project, Brazil's first utility-scale battery storage system in the transmission segment, has been supporting a substation serving 15 municipalities and roughly 2 million residents since December 2022.
CATL's local service network now includes five senior storage specialists and more than 140 certified engineers across South America. They support a tiered response framework: one-hour remote support, two-day on-site dispatch, and five-day cross-regional expert escalation. Regional inventory is backed by four global core warehouses and over 50 front-end stocking points, with core spare parts guaranteed for up to 20 years.
