Castri Mobile Energy Storage Container with Ultra-Large Capacity

Is CATL launching a new energy storage system?

CATL (SHE: 300750) has rolled out a new energy storage system called Tener Stack in a bid to consolidate its position in the sector. The Chinese battery giant launched the Tener Stack at the battery storage show in Munich, Germany, on May 7, calling it the world's first production-ready 9 MWh ultra-high-capacity energy storage system solution.

Is CATL Tener energy storage a Bess system?

"CATL has always been at the forefront of the energy transition," said Amanda Xu, CTO ESS & President of ESS Europe CATL. "To meet the expectation of a BESS system that has high energy density, small footprint, simpler AC-side configuration, and flexible deployment, we bring the latest CATL TENER energy storage solution.

How much power can Tener stack charge?

The internal capacity reaches up to 9MWh, which is adequate to charge 150 electric cars or power an average German household for six years. To enhance compatibility and system efficiency, TENER Stack supports both centralised and string PCS (Power Conversion System) architectures.

Can Tener stack reduce container usage?

Developers deploying 800 MWh with TENER Stack could reduce container usage by one-third and cut construction costs by up to 20%. To address logistics challenges, CATL introduced a modular “two-in-one” design. Each unit remains under the 36-tonne transport limit, enabling compliance across 99% of global markets and reducing shipping costs by 35%.
