Netherlands-based power provider Eneco has completed its large-scale storage project in Schleswig-Holstein. “EnspireME” has a capacity of 48 MW, a storage capacity of more than 50 MWh and consists of about 10,000 lithium-ion batteries. It is the largest storage project realized in Europe to date, the company stated. The battery in, Jardelund, close to Germany's border with Denmark, is large enough to supply about 5,300 households with electricity for 24 hours.
The storage system is to be used in the future for the primary control energy market. It could thus replace conventional power plants, which previously provided the control energy. The system operators want to participate in weekly auctions for primary reserve capacity.
In addition, Eneco and Mitsubishi, with the support of the regional government, also want to look for ways to connect wind farms located in the area with the battery storage. In times of high wind power production, an overloading of the network should thus be prevented. At the same time, the two companies aim to prevent the shutdown of the plants by the grid operator by temporarily storing the wind power.
In April 2017, Eneco and Mitsubishi announced the construction of the facility near the Danish border. It was also said at the time that it was to be developed near a high voltage station. This has the advantage that the battery could contribute to reducing the regular energy losses at high voltage stations.
