Many MindedCATL's 9-MWh Tener+ packs more storage into fewer containers
CATL launched Tener+, a 9-MWh grid energy storage system, at All Energy Australia 2026 in Melbourne on October 28. The company says it can cut the containers a project needs by up to 40% and shrink the site footprint by 12%, compared with conventional solutions. It lists a 25-year design life and proprietary cells meant to slow degradation. It follows the 6.25-MWh Tener of April 2024 and the 9-MWh Tener Stack of May 2025.
Some design details: a top-exhaust layout sends hot air upward, which CATL says lets the power conversion systems hold full rated output in harsh summer heat. Cell options include a high-temperature version and one with three years of zero degradation, though that option is not offered on every configuration. Several units can be commissioned at once with one click.
The same day, CATL showed its sodium-ion Tener Sodium system in Australia for the first time. It was launched in June 2026 and offers over 30 MWh of system-level capacity. It is rated for over 10,000 cycles at 45°C. CATL also announced a 3 GWh sodium-ion supply deal with Germany's Intilion over five years, plus memorandums of understanding with Hitachi Energy, EPEC Group and UNSW Sydney. The UNSW agreement includes a planned training and innovation center in Western Sydney.
Why it matters: storage is what turns intermittent solar and wind into power available on demand. Fewer containers and less land per MWh lower installation costs, and heat-tolerant, long-life systems suit hot grids like Australia's. Sodium-ion adds a second chemistry that does not depend on lithium.
The caveats are real. The container, footprint, lifespan and output claims are CATL's own, unverified, and are 'up to' figures against unspecified baselines. Tener+ is a launch, not proof of field performance. CATL's scale is large, with 125.0 GWh shipped in H1 2026 and a 27.1% global share per SNE Research, which also means concentrated supply.
