Developer Kyon Energy has sold 194.7MW of battery energy storage system (BESS) projects in Germany to investor Obton, including one it recently claimed was the largest in Europe.
Three of the project sales have already concluded over the course of 2023 while a fourth is set to conclude before the end of the year. They are part of a 600MW framework agreement that Kyon and Obton announced in June 2023.
The four projects are:
- a 15.8MW/35MWh project in Tangermünde, Saxony-Anhalt
- a 20.7MW/41.4MWh project in Karstädt, Brandenburg
- a 137.5MW/275 MWh project in Alfeld, Lower Saxony
- an unspecified project with a power capacity of 20.7MW, still to be transferred

Construction on all four projects will start next year. The four total 194.7MW of power and at least 350MWh of energy storage capacity with the fourth project’s MWh not revealed. Two previous 20.7MW projects that Kyon worked on were 1-hour systems.
BESS projects in Germany are generally moving to longer durations of 2 hours or more with the revenue advantage of these versus 1-hour systems growing as Energy-Storage.news recently wrote (Premium access).
The 275MWh Alfeld project was claimed to be the ‘largest in Europe’ by Kyon when it announced the regulatory green light to build it last month, though this claim would only be true if you exclude the UK as Energy-Storage.news observed in its coverage at the time. And with construction yet to start it could feasibly be usurped by another project.
“Battery storage systems make a significant contribution to building a resilient energy infrastructure based on renewable energies and thus to achieving the energy and climate targets. The fact that we were already able to contribute 200 MW to the framework agreement in the first year is a major milestone and reflects our commitment to driving forward the energy transition in Germany,” said Florian Antwerpen, Managing Director of Kyon Energy.
Alongside helping to achieve renewable energy deployment goals, grid-scale energy storage could save the German taxpayer €3 billion a year by 2037 according to developer and system integrator Eco Stor. Eco Stor has deployed projects for Kyon, including the aforementioned paid 20.7MW systems.
Energy-Storage.news did a deep-dive on the German grid-scale market for an edition of PV Tech Power, Solar Media’s quarterly journal, last year.
Energy-Storage.news’ publisher Solar Media will host the 9th annual Energy Storage Summit EU in London, 21-22 February 2024. This year it is moving to a larger venue, bringing together Europe’s leading investors, policymakers, developers, utilities, energy buyers and service providers all in one place.
