February 14, 2025: German lithium battery storage systems specialist Tesvolt has launched a spin-off business, Tesvolt Energy, targeting the energy trading market using BESS systems of 100kWh and above.

Tesvolt said on February 5 that, to date, battery storage systems of that magnitude have been excluded from highly complex energy trading or only accepted on less lucrative terms. 

Now Tesvolt Energy — officially launched at the E-world energy trade fair in Essen this week — will work with German firms Enspired, Entrix and The Mobility House for front-of-meter energy trading.

The aim of the cooperation is to open additional sources of income for operators while also supporting grid stability.

Tesvolt Energy will focus on pooling the capacities of BESS systems between 100kWh and 10MWh to form a virtual power plant.

The start-up said it has developed software that ensures battery storage systems in the pool generate the greatest possible revenue with the least intensive operations. 

The energy trader that generates the highest revenues with the least intensive operation of the storage systems gets to manage the most battery systems in Tesvolt Energy’s pool.

This means higher revenues and lower risk because all revenue goes into a pot and is distributed in the style of a cooperative at the end of each month.

Tesvolt Energy said it already has battery storage systems with a total capacity of 100MWh in the pipeline. 

Tesvolt co-founder and CEO Daniel Hannemann, said: “Commercial and industrial companies have enormous potential for bringing urgently needed flexibility to the utility grid with battery storage systems. 

“But in competition with the big battery park operators, they often have no chance of finding a good trader who will trade their storage capacity on the utility grid.”
