Germany’s battery storage sector is about to experience significant growth in the coming years as outlined in a previous article. In 2022, a reported 434MW of battery storage projects were connected to the grid which was a record for the Germans. In this article, we will introduce three landmark battery storage projects that have been developed in the country. All of the projects were developed by firms that can be found on our list of large European developers of storage energy projects.
Neurath & Hamm – RWE’s 220MW battery storage project
In November 2022, RWE outlined plans to develop a 220MW battery storage project in Neurath and Hamm in North Rhine-Westphalia. The project will require an investment of €140m and is expected to undergo construction in 2023 and grid connection by 2024. The project will consist of 690 lithium-ion batteries spread across sites at Neurath and Hamm. Hamm will be a larger site, with an installed capacity of 140MW whereas Neurath will have an installed capacity of 80MW. The project represents a cornerstone for RWE’s goal of developing 3GW by 2030.
Lingen & Werne – RWE’s 117MW battery storage project
RWE developed two battery storage projects to store energy generated from its hydropower plants, which increased the capacity of the site by 15% and required an investment of €50m. In January 2023, the German group announced the completion of its 117MW site, a project which took 14 months. The project consists of 420 blocks of lithium-ion batteries and has been connected to RWE’s run-of-river power plants along the Moselle river.
Wunsiedel – Siemen’s 100MW battery storage project
In July 2021, Siemens began construction for its 100MW battery storage project located in Wunsiedel, northern Bavaria. The project is being co-developed with Fluence, which will provide the lithium-ion battery system. Wunsiedel represents a hub of Siemens activity, as the area will also contain an 8.75MW green hydrogen plant which is also under development. The storage project will use surplus renewable energy which will maintain energy supply at times of high demand, with the capacity to supply 20,000 households.
