VIK Jahrestagung
08. October 2026
Berlin, Humboldt Carré
On 8 October 2026, the 79th VIK Annual Conference in Berlin will bring together decision-makers from energy-intensive industries, politics and academia. The focus is on key industrial and energy policy decisions, ranging from power prices and site competitiveness to transformation pathways such as hydrogen and carbon management.
Entelios will be on site to demonstrate how industrial companies can leverage flexible loads, storage and distributed generation to reduce energy costs and deliver on their climate targets. Meet our team to discuss how intelligent flexibility marketing can strengthen the competitiveness of your production sites.
4th BVES Investor Summit Europe 2026
14. October 2026
– 15. October 2026
WECC – Westhafen Event & Convention Center, Berlin
The 4th BVES Investor Summit Europe brings together investors, financiers, project developers, utilities and policymakers. The programme will focus on energy storage as a new infrastructure asset class, European storage markets, financing and revenue models as well as the bankability and grid integration of BESS projects.
Entelios will attend the event. Our team will be available for discussions on battery storage, cross-market optimisation and the trading of BESS across spot and ancillary services markets.

The two large-scale battery storage facilities operated by Münch Energie in Saxony-Anhalt expand the available storage capacity for a more flexible and increasingly renewable energy system. Each facility has a capacity of just under 50 MW and approximately 100 MWh of storage capacity. Together, the two battery storage facilities can store approximately 200 MWh of electrical energy and feed it back into the power grid as needed. According to Münch Energie, the combined storage capacity ranks among the largest of its kind in Germany.
With an output of 6.4 MW and a capacity of 21.6 MWh, Stadtwerke Hünfeld operates what is currently the largest battery storage system in Hesse. As a so-called three-hour system, the storage facility is particularly well suited to responding to short-term fluctuations in the power grid – a feature that is becoming increasingly important as the share of renewable energies rises.
The trading is carried out through Cross-Market-Optimisation, which specifically includes all relevant markets – including balancing energy (FCR and aFRR) as well as day-ahead and intraday markets. Entelios is responsible for the technical integration and...
With the successful prequalification of the Schkölen ground-mounted PV plant (37.4 MWp) for the aFRR market, we have set a milestone in the energy transition together with Sunnic Lighthouse and 50Hertz.
For the first time, a PV plant in Germany is performing grid-supporting tasks in the control energy market – both by reducing output in the event of a power surplus and by feeding power into the grid in the event of a shortfall.
The stand-alone battery storage facility in Karstädt strengthens Obton A/S's regional grid stability while also benefiting from market-optimised flexibility trading. The BESS has a power capacity of 20.7 MW and an energy capacity of 35 MWh and is traded by Entelios on several short-term markets such as the intraday and balancing energy markets.
Thanks to its medium-voltage grid connection (20 kV) and its geographical location in the 50Hertz control area, the storage facility is optimally integrated into the German electricity grid. The focus is on data-based cross-market optimisation, which allows the available flexibility to be used...
With another large-scale storage facility in Tangermünde, Obton A/S is expanding its German storage portfolio with another strategically located project in the 50Hertz control area. The front-of-the-meter storage facility, with a power capacity of 15.8 MW and an energy capacity of 32 MWh, contributes to local grid stability and enables cost-effective marketing on short-term markets.
Entelios is responsible for automated cross-market optimisation, including participation in the PRL and SRL balancing energy markets and active management on the day-ahead and intraday markets. Intelligent control maximises revenues while making a useful...
In Föhren, Rhineland-Palatinate, SCHOENERGIE is implementing an innovative combination of photovoltaic and battery storage. The 21 MW / 55 MWh battery storage system is directly coupled with a 17 MW PV plant and is connected to the grid via a 20 kV medium-voltage interface.
Since October 2025, Entelios has been trading the system across various short-term electricity markets (FCR, aFRR, Day-Ahead, Intraday), ensuring optimal revenue generation. The project also uses our Cross-Market Optimisation, which has been specifically designed for co-located systems. The battery storage unit is operated in Amprion's grid zone and delivers important...
With an output of 137.5 MW and a capacity of 306 MWh, one of the largest battery storage facilities in Europe is being built in Alfeld, Lower Saxony. The project, realised by Entelios, enspired and Obton, is intended to strengthen grid stability, integrate renewable energies and drive forward the energy transition from 2026. The storage facility ensures grid stability by participating in balancing markets, stores surplus energy and optimises market integration. The partnership combines Entelios' marketing expertise, enspired's AI optimisation and Obton's investment and sets new standards for large-scale storage technology.
ECO POWER ONE, a pioneering battery storage project by ECO STOR GmbH in Bollingstedt, Schleswig-Holstein, marks a significant advancement for the energy transition. With a power capacity of 103.5 MW and an energy capacity of 238.5 MWh, the battery system will make a substantial contribution to grid stability and energy security starting in January 2025.
The battery power plant of Versorgungsbetriebe Bordesholm (VBB) has been in operation since 13 May 2019 and serves as a prime example of a sustainable and decentralised energy supply throughout Germany. With an output of 15 MW and a capacity of 15 MWh, the power plant is in normal operation in the balancing energy markets and on the spot and intraday markets. In the event of a failure of the upstream transmission grid, the battery power plant for Bordesholm enables a self-sufficient, off-grid and black-start capable supply from 100% renewable energies from PV, biogas plants and CHP units.
With the launch of the new SEAL system service product on 22 May 2024, industrial flexibility will be used to stabilise the grid. SEAL replaces the Switch-off Loads Ordinance (AbLaV), which expired in June 2022, and enables electrical consumers to be switched off quickly in order to stabilise the grid frequency.
Entelios AG is the first marketer in Germany to qualify for SEAL. Since July, two Alzchem carbide furnaces with a total output of 50 MW have been successfully marketed. The systems can be switched off at short notice in the event of grid fluctuations and quickly switched back on again.
