The storage manufacturer Tesvolt has founded a company that markets electricity from battery storage systems with a capacity of 100 kWh or more.

With the newly founded Tesvolt Energy, electricity trading should also pay off for users of small battery storage systems in the future. Until now, battery storage systems between 100 kWh and 10 MWh were "excluded from highly complex energy trading or could only participate on less lucrative terms", according to a statement from Tesvolt. This is now set to change. The company bundles storage units between 100 kWh and 10 MWh into a virtual power plant and brings the electricity to the market. To this end, Tesvolt Energy is working together with energy traders Enspired, Entrix and The Mobility House. The selection of three marketers puts them in competition with each other, it continues.

"The energy trader that generates the highest revenue with its trades while operating the storage system as gently as possible will be allowed to manage the most battery systems in our pool," explains Sebastian Kratz, who heads the new company together with Anshoo Pandey.

The end result should be higher revenues and less risk for the customer. "All proceeds go into one pot and are distributed fairly and transparently among the customers at the end of the month - similar to a cooperative."

Tesvolt Energy has developed software that controls the storage systems in such a way that they generate appropriate revenues while remaining durable. Here, the company benefits from the expertise of its parent company Tesvolt AG.

To date, Tesvolt Energy has battery storage systems with a total capacity of 100 MWh in the pipeline. Several more are to be added by the end of the year. "The return on investment is usually three to four years. An economically convincing argument for anyone who wants to invest in a commercial storage system and has a grid connection point," says Tesvolt Managing Director Pandey.
