New TESVOLT subsidiary paves the way for profitable energy trading with commercial storage systems

Berlin, Wittenberg, 5 February 2025 – TESVOLT, an innovation and market leader for commercial and industrial energy storage system solutions in Germany and Europe, has announced a spin-off: TESVOLT Energy. The start-up’s business model makes energy trading with battery storage systems of 100 kWh and above not only possible but profitable as well. Until now, battery storage systems of this magnitude were excluded from highly complex energy trading or only accepted on less lucrative terms. Here TESVOLT Energy is working with Germany’s most renowned traders: Enspired, Entrix and The Mobility House. The new company debuts at E-world in Essen from 11 to 13 February.

Bringing the full scope of usable flexibility to the utility grid

"The volatility of renewable energy suppliers means the electricity grid needs all the buffer power it can get. 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,” explains Daniel Hannemann, co-founder and CEO of TESVOLT AG. “With TESVOLT Energy, we are providing commerce and industry with a very, very lucrative opportunity for taking part in front-of-the-meter energy trading.”

A one-of-a-kind first: competing traders

TESVOLT Energy focuses on battery storage systems between 100 kWh and 10 MWh and incorporates them into a pool. Numerous smaller storage systems can thus combine to form a virtual power plant. “What no one else on the market can offer so far: we don’t just work with one trader, we work with three – the leading traders in Germany, no less – and put them in competition with each other. The energy trader whose trades generate the highest revenues with the least intensive operation of the storage systems gets to manage the most battery systems in our pool,” explains Sebastian Kratz, who is heading the new company together with Anshoo Pandey. “For our customers, this means higher revenues and lower risk, because all revenues go into a pot and are distributed fairly and transparently among the customers at the end of the month – much like they are in a cooperative.” 

Proprietary software ensures optimal storage management

The start-up has developed software that controls the battery storage systems in the pool so that they generate the greatest possible revenue with the least intensive operations. This ensures a significantly longer service lifespan. In developing the software, TESVOLT Energy also benefited from TESVOLT AG’s many years of expertise in battery storage.

100 MWh in the pipeline already

“We already have battery storage systems with a total capacity of 100 MWh in the pipeline. With such an attractive, transparent model, we will have many more by the end of the year. The return on investment is usually three to four years. It’s a compelling economic argument for anyone looking to invest in a commercial storage system and has a grid connection point,” says Anshoo Pandey, Managing Director of TESVOLT Energy.
