CATL Makes Big Push in Brazil with New Partner and Full Storage Lineup

The headline act is TENER S, CATL's latest storage solution. It's designed to last 20 years, and here's the kicker – zero degradation in both capacity and power during the first year of operation. The integrated liquid cooling system cuts auxiliary power use by up to 20%, which trims operating costs over time. It also packs 30% more energy density into the same footprint while shrinking the site size by 20%, lowering balance-of-system costs. That's a real advantage in a market where grid instability keeps complicating renewable integration. TENER S has already landed some big international projects, including a 1.5 GWh installation in Spain and the Supernode development in Australia, where it comes with a long-term service agreement.

For utility and industrial/commercial applications that need serious density, CATL is showing off TENER H. It uses 575 Ah cells to squeeze 9,008 kWh into a single container, which improves land utilization by 45% – a meaningful cost win in areas where real estate doesn't come cheap. The system supports flexible 2-, 4-, and 8-hour configurations. The 2-hour version is built for fast grid stabilization, while the longer-duration setups hit up to 96.0% round-trip efficiency, maximizing returns on extended discharge cycles.

Also new to Brazil is TENER Sodium, a 30 MWh integrated sodium-ion system that CATL only launched globally a short while back. It comes with a 20-year design life, 95% round-trip efficiency, and stable operation across a -20°C to +45°C temperature range, plus IEC/UL/CE certifications. Beyond the cells themselves, the system coordinates battery management, power conversion, and thermal management – all optimized for sodium-ion chemistry – which speeds up site deployment and improves reliability in the field. Industry watchers note that TENER Sodium pushes CATL's site-level engineering and full-lifecycle asset management know-how into the sodium-ion space, building on years of turnkey project deliveries worldwide and backed by the company's new whole-station testing facility in Xiamen, which validates grid-connected performance under real-world conditions.
