Battery storage
Maximizing returns on all energy markets!
We optimize the revenues of your battery storage systems - through active trade management and precise market integration.
By September 2025, around 2.35 GW of installed capacity and 2.9 GWh of usable storage capacity of large-scale battery storage systems (utility-scale / industrial) will be in operation in Germany. In the first half of 2025 alone, 73 new large-scale storage facilities were built, providing an additional ~510 MW of output and ~690 MWh of storage capacity.
We market, control and optimize battery storage systems - stand-alone, co-located or directly at industrial sites.
Whether as a stand-alone unit, in combination with wind and solar systems or to cover your own needs on factory premises: Our solutions integrate battery storage systems seamlessly into the electricity market and maximize their economic benefits. With a deep understanding of the market, precise control and a clear focus on flexibility marketing, we tap into new revenue potential - from intraday trading to grid-supporting ancillary services. This is how we make storage a strategic component of your energy future.
