A pair of 20.7MW battery energy storage systems have been added to the electricity grid in Bavaria, Germany, by Austria-based utility Verbund and developers ECO STOR and Kyon Energy.
The CEOs of Verbund, ECO STOR’s parent company Agder-Energi and Kyon Energy will officially inaugurate the two projects in the municipalities of Diespeck and Iphofen on 30 January, 2023. The ceremony will also be attended by state minister Hubert Aiwanger.
While the event is being described as a commissioning ceremony, ECO STOR’s battery storage market monitor says both lithium-ion battery systems have been in commercial operation since September/October last year.
Diespeck is a 20.7MW/20.7MWh unit while the Iphofen facility has power output and energy capacity of 20.7MW/20.1MWh.

Verbund is the project owner through its central trading platform entity VERBUND Energy4Business GmbH while ECO STOR provided the battery storage technology and engineering, procurement and construction (EPC) services.
Kyon Energy did early-stage project development for the sites through providing a lease contract, getting construction approval and grid access contract before passing on the project to final owner Verbund.
Kyon said that the Iphofen project uses battery cells from LG Chem while the Diespeck unit is equipped with Samsung SDI cells. Both will provide grid services, mainly primary control reserve (PCR) which involves injecting power into the grid when frequency deviates from 49.99-50.01 Hz.
They will also generate revenues from trading energy on the spot market as well as providing ‘avoided network charges (§ 18 StromNEV)’, Kyon said. Energy-Storage.news understands the latter is the ‘peak shaving’ service which is not available for battery storage projects commissioned after 2022, explained by ECO STOR’s managing director Georg Gallmetzer in an earlier interview.
Verbund is an Austria-based electric utility which ECO STOR has previously provided battery storage projects for, including one commissioned last year in Eisenach. ECO STOR is one of the main companies providing battery storage system integration in the German market, with over 100MWh deployed last year.
Kyon Energy meanwhile has developed, sold or commissioned 121MW of battery storage in the country by the end of 2022, according to head of business development & regulatory affairs Benedikt Deuchert in an interview in October.
Growth in the utility-scale energy storage sector returned to Germany in 2022 after several years of stagnancy. See all Energy-Storage.news’ coverage of the country’s energy storage market here.
