Lingtech announces 3 MW / 6MWh grid-forming BESS

Chinese battery manufacturer Lingtech has unveiled a new battery energy storage system (BESS) for utility and large commercial and industrial (C&I) use.

Called the 6MWh 3MW Grid-Forming BESS, the system features a storage capacity of 6 MWh and nominal AC power of 3MW.

“The core of the system lies in its ability to mimic the inertia response of traditional synchronous generators, that is, its grid-forming technology (GFM),” said the company. “It provides primary frequency regulation, voltage support, and black-start capability to restart the grid in the event of a total blackout.”

Lingtech further explained that the new product opeates as a controlled voltage source and can independently set and maintain the grid’s voltage and frequency.

The BESS uses lithium iron phosphate (LFP) battery cells with intelligent liquid cooling. It measures 6,058 mm × 2,896 mm × 2,438 mm and weighs 27,000 kg. Its operating ambient temperature range is -30 C to 50 C, while its maximum operating altitude is 4,000 m. It holds an IP55 protection rating and a C3  anti-corrosion rating.

“The system supports PV integration, ensuring that solar panels continue to charge the battery and power loads even when the main utility grid is down. This eliminates the ‘curtailment’ issue where solar generation is wasted during outages,” adds the company. “It supports seamless connection and switching between PV, the main grid, diesel generators, and the BESS itself. This hybrid capability allows for microgrid formation and ensures maximum uptime for critical loads.”
