BESS developer Kyon Energy has commissioned and put into operation its 137.5MW/282MWh Alfeld BESS project in Germany, potentially the country’s largest to reach that milestone.
Kyon announced the commissioning of the battery energy storage system (BESS) project in Lower Saxony on LinkedIn yesterday (27 October).
The project is in the service area of DNO Avacon Netz, which Kyon thanked along with Engira, another developer and renewables services provider which also worked on the project.
Kyon secured planning approval for the project in late 2023, when it ambitiously called it the ‘largest BESS project in Europe’, although made no such claim in its post yesterday. Since then Germany has moved up in scale, with several gigawatt-hour projects in construction including three announced this month.

The Alfeld project is part of a portfolio of Kyon projects that Belgium-based investor Scale Fund is financing and owning. Battery analytics firm Twaice is providing its services on the project while renewables developer and services firm BayWa r.e. is doing O&M and technical asset management.Â
Shortly after BayWa r.e. won the contract, the firm’s MD data services Simon Slapka spoke to us about the state of play for O&M and asset management in BESS today for an ESN Premium video interview article.Â
Kyon Energy was acquired by oil and gas major TotalEnergies in January 2024 and is building a 789MW/1,628MWh portfolio of BESS projects in Germany for its parent company, but the Scale Fund’s investment pre-dated that deal so Kyon has continued to work with it. TotalEnergies then divested 50% of that portfolio to Allianz GI this year.Â
The Alfeld news comes as Germany’s grid-scale storage market enters a phase of busy project execution ahead of a 4 August 2029 commissioning cut-off date for projects to be exempt from charge-discharge grid fees.Â
Our publisher Solar Media, part of Informa Markets, held the Energy Storage Summit Germany in Berlin last month where grid fees and flexible connection agreements (FCAs) were among the biggest topics.Â
