CATL Books 3 GWh European Sodium-Ion Power Storage Pact With Intilion Across Five-Year Term
CATL has entered a five-year commercial partnership with German storage integrator Intilion to supply 3 GWh of sodium-ion stationary battery systems across central Europe.
- 3 GWh
- 5 years
- 15,000 cycles
- 25 years
What Happened
CATL concluded a five-year supply pact with German energy storage specialist Intilion on October 27, 2026, agreeing to deliver 3 GWh of sodium-ion power storage units to European project developers.
- 3 GWh across five years
- 25 years of service
- Over 15,000 charge-discharge cycles
The equipment deliveries will center on central European power markets, deploying containerized stationary storage across Germany, Austria, and Switzerland for utility-scale electrical grid balancing alongside commercial and industrial installations.
CATL developed the Tener Sodium system to withstand sub-zero operating environments, offering cold-weather discharge performance at temperatures reaching minus 20 Celsius while eliminating thermal-runaway and raw-material sourcing constraints associated with traditional lithium cells.
The transaction builds upon a technical relationship begun in 2022 that has installed over 30 stationary energy storage facilities throughout Germany using conventional lithium-ion cells.
Why this matters
The multi-gigawatt-hour contract marks a major European commercialization milestone for alternative battery chemistries that avoid critical mineral bottlenecks like lithium, nickel, and cobalt. By deploying cold-resilient sodium-ion hardware across Germany, Austria, and Switzerland, CATL is validating non-lithium chemistries for grid-scale and commercial power reserves.
