Each Battery Energy Storage Unit (BESU) combines two liquid-cooled LFP battery containers with an inverter, transformer, medium-voltage switchgear and low-voltage main distribution board. A single unit provides 8.1 MWh of storage capacity and 4.6 MW of power. The battery containers are supplied by CATL. Proprietary control units link the components into a unified system and allow integration into industrial and grid applications.
The standardised architecture is designed to reduce planning effort and accelerate installation and commissioning. According to the manufacturer, the system can achieve technical availability of 97%. It is aimed at project developers, energy suppliers and investors. (nhp)
