At ees Europe 2025, CATL launched TENER Stack, the world’s first mass-produced 9MWh ultra-large-scale energy storage solution, setting a new industry benchmark for power capacity, deployment flexibility, and logistical efficiency. Designed for utilities, developers, and industrial users, this innovation addresses surging energy needs driven by AI expansion and the clean energy transition.

More Power, Less Space

● 9MWh per unit—enough to charge 150 EVs or power a German household for 6 years.

● 45% better space efficiency vs. standard 20ft containers, cutting land use by 40%.

● 20% lower construction costs for large-scale projects (e.g., an 800MWh facility needs 30% fewer containers).

Smarter Design, Easier Deployment

● Works with both centralized and string inverters, ensuring compatibility with existing grid infrastructure.

● "Two-in-one" transport system keeps each half-unit under 36 tons, complying with 99% of global shipping regulations.

● 35% faster & cheaper logistics—no specialized trucks needed, ideal for remote or urban sites.

Unmatched Safety & Reliability

● CATL’s LFP batteries—zero degradation for 5 years, with 40% faster fire detection and 2-hour fire resistance.

● Withstands extreme conditions: Magnitude 9 earthquakes and Category 5 hurricanes (IEEE693-certified).

● Quiet operation (65dB), making it suitable for cities.

Why It Matters

With over 1,700 global deployments, CATL continues to push energy storage boundaries. TENER Stack builds on its TENER (zero-degradation) and TENER FLEX (modular rack) systems, offering unprecedented energy density and cost savings.

Hank Zhao, CTO of ESS Europe at CATL, stated:
"9MWh is just the beginning. Every future breakthrough in energy density will unlock even greater value—delivering more power in less space, safely and sustainably."

TENER Stack isn’t just an upgrade—it’s a game-changer for grid stability, renewable integration, and industrial energy needs worldwide.
