According to foreign media reports, energy storage developer JT Energy Systems has deployed a 25MW battery energy storage system in Germany, which uses secondary batteries used by electric vehicles, including forklifts.
JT Energy Systems is a joint venture between Triathlon, a German lifepo4 battery manufacturer, and Jungheinrich AG, a logistics company. The company opened and  operated the battery energy storage system on September 30, claiming  that it is the largest battery energy storage system operated in Saxony  and the largest battery energy storage system of its kind. The  construction of the energy storage system will start in January 2022.
The two companies said that the battery energy storage system will  mainly provide the load transfer function to store energy during the  period of excess power supply, so as to provide power to the grid when  needed.
Reinhild K ü hne, general manager of JT Energy Systems, said,  "Especially considering the current energy shortage, we need effective  methods to store renewable energy. The battery lithium solar energy storage system is an ideal solution, which will help stabilize  energy prices and successfully achieve energy transformation."
A large part of the 10000 liFePo4 lithium battery modules that make up the 25MW battery energy storage system are rechargeable  lithium ion batteries, mainly from electric forklifts of Jungheinrich  AG, and some are from electric buses.
K ü hne added, "The service life of lithium-ion batteries is usually  longer than that of motor vehicles. In order to reasonably continue to  use batteries for a long time in the future, the fixed energy storage  system we installed in Freiburg is a logical result."
The battery energy storage system is planned and built by TRICERA  Energy, a partner of JT Energy Systems. TRICERA focuses on the use of  electric vehicle batteries to build solar battery storage system . Lars Fallant, the company's chief operating officer, said that this  approach is feasible thanks to the existing large car industry in  Germany.
K ü hne said: "Due to the rapid increase in the share of electric  vehicles using lithium ion batteries in the past few years, JT Energy  Systems expects that more and more secondary batteries will be used to  build fixed lithium iron solar battery systems in the future."
Although the residential, commercial and industrial (C&I) sectors  maintain strong growth, according to a study, the German public utility  scale energy storage market has developed slowly in recent years, and  only 32MW energy storage solar system lithium battery will be installed in 2021.
