CATL launched its 9 MWh TENER+ ESS globally at All-Energy Australia 2026
The liquid-cooled system offers a claimed 25-year design life and reduces container requirements by up to 40%
The company also showcased its TENER Sodium system, designed to operate at temperatures up to 55°C
Battery manufacturer CATL officially launched its 9 MWh TENER+ energy storage system (ESS) globally at All-Energy Australia 2026 in Melbourne. The company also showcased its TENER Sodium system and announced partnerships to support large-scale energy storage projects in Australia.
TENER+ offers a storage capacity of 9 MWh per unit. CATL has equipped the system with liquid cooling and intelligent thermal management to improve efficiency during charging and discharging. The company says the higher capacity can reduce container requirements by up to 40% and installation space by 12%. The system operates at noise levels below 65 dBA, measured at a distance of 1 m. CATL states that TENER+ is designed for a 25-year service life, with protection against high humidity and coastal conditions.
With sodium-ion batteries emerging as an alternative to lithium-ion technology, CATL also showcased its TENER Sodium ESS. Sodium's wider availability offers an opportunity to diversify battery supply chains. CATL says the modular system can support installations exceeding 30 MWh and operate at temperatures up to 55°C. It is designed to deliver more than 10,000 charge-discharge cycles at 45°C, with a claimed round-trip efficiency of 95% and a service life exceeding 20 years. CATL previously presented the TENER Sodium system at Intersolar Europe 2026, where the company discussed its modular design, operating flexibility, and battery performance in an interview with TaiyangNews (see CATL Migrates To Sodium-Ion BESS Technology).
"The value of the battery must be measured by the lifetime of the project, not just the start date," said Zane Zhou, General Manager of CATL Australia and New Zealand.
Alongside the product launch, the company signed memorandums of understanding (MoUs) with Hitachi Energy, EPEC Group, and UNSW Sydney. The cooperation with Hitachi Energy will focus on integrating CATL's DC battery systems with Hitachi Energy's power conversion technology. The collaboration with EPEC Group and the Xiamen Energy Storage Validation Research Institute (ESVL) will address grid integration, engineering and system performance validation.
CATL and UNSW Sydney also plan to establish a renewable energy training and innovation center in Western Sydney to support workforce development and technical capabilities for Australia's energy transition.
The announcement follows CATL's involvement in the 400 MW/1,860 MWh Baranduda Energy Reserve project in Victoria, where Birdwood Energy has selected the company as a technology partner.
