Commercial and industrial (C&I) BESS provider Tesvolt has begun construction of its latest 4GWh manufacturing plant in Germany.

The new plant will be next to its existing assembly plant in Lutherstadt Wittenberg, Saxony-Anhalt, and will be able to produce 80,000 of the company’s battery energy storage system (BESS) products a year, totalling 4GWh, at full capacity.

As Energy-Storage.news reported when Tesvolt announced the new plant, it will grow the company’s manufacturing capacity 10-fold and is set to enter operation in 2025.

The company calls it a gigafactory, although Energy-Storage.news reserves this term for facilities building lithium-ion battery cells, which Tesvolt will need to buy from abroad – most likely China. Europe is hoping to build its own lithium-ion cell manufacturing capacity, but this will mostly be used for EVs. A second construction phase will see a research and development (R&D) centre built at the site.

The company is the largest supplier of BESS to the C&I market, which is much larger in Germany than many other countries. C&I customers can use the BESS units to increase solar self-consumption – distributed solar is heavily incentivised in Germany – and reduce electricity bills in other ways like peak shaving.

Tesvolt recently said in February 2024 that it also aims to ‘conquer’ the C&I energy storage market in Italy, setting up an office in Milan to facilitate market access.
