Battery storage capacity in Germany is growing rapidly: by mid-2024, 1.8 GWh had already been installed in large-scale storage facilities. According to forecasts by the German Federal Office for Solar Energy, the capacity of large battery storage systems could increase fivefold to a total of around 8.8 gigawatt hours by 2026. This means that storage systems not only play a key role in ensuring a stable electricity grid, they also create new economic opportunities for operators.
Against this backdrop, The Mobility House Energy and TESVOLT Energy are joining forces with immediate effect: together, the two companies are offering a complete front-of-the-meter marketing solution for battery storage systems. The aim of the cooperation is to open additional sources of income for operators and support grid stability at the same time.
TESVOLT Energy, a subsidiary of Tesvolt AG, which develops and sells storage solutions itself, is thus expanding its portfolio to include a comprehensive energy management service for commercial and industrial customers. TESVOLT customers can now benefit from a fully integrated marketing offering that was previously reserved primarily for large-scale battery storage systems.
Future-proof energy systems for the energy transition
This Trading-as-a-Service cooperation makes it possible to control battery storage systems precisely and in real time - and thus make the most of market opportunities. The result is a particularly efficient and flexible solution that offers operators of large-scale battery storage systems considerable added value: The multi-market strategy for flexibility marketing ensures maximum revenue while also helping to stabilize the electricity grid.
The partnership between The Mobility House Energy and TESVOLT marks an important step towards the integration of renewable energies into the energy system. Large-scale battery storage systems stabilize the power grid by absorbing surplus energy from renewable sources and releasing it again in fractions of a second when needed - thus balancing out fluctuations and reducing the risk of grid bottlenecks. At the same time, they increase their profitability by participating in electricity and balancing energy markets. This allows operators to generate additional income and makes the overall system more efficient.
Algorithm-based real-time optimization through “FlexibilityTrader”
The Mobility House Energy has been specializing in the marketing of decentralized, grid-bound flexibility on European power and energy markets since 2016. To this end, the company operates an energy trading floor with direct access to various markets. As part of the cooperation, The Mobility House Energy acts as a white label optimizer.
The flexibility potential of the battery storage systems connected to the pool is divided into individual capacity slices (“virtual assets”). With the help of the FlexibilityTrader, the algorithm-based technology, The Mobility House Energy markets these virtual assets around the clock in the best possible way within the framework of the respective marketing parameters and available marketing options - and optimizes them economically.
Since January 2025, The Mobility House Energy has already been marketing the flexibility potential of TESVOLT assets on the short-term wholesale markets (day-ahead and intraday markets). Integration into the regular reserve markets will follow in the second half of 2025. Here, the virtual assets will also be marketed in the Frequency Containment Reserve (FCR) and the automatic Frequency Restoration Reserve (aFRR).
