Dutch energy firm Eneco and Japanese company Mitsubishi have formed a joint venture EnspireME to build a 48MW, 50MWh energy storage system in Germany.

Considered to be the largest energy storage system in Europe, the facility comprises of a lithium-ion system and can support consumption of about 5,300 local households.

The energy storage plant will be located in the municipality of Jardelund in Schleswig-Holstein. The place, which is close to the border of Denmark has been one of the pioneering states in renewable energy in Germany.

The battery system including the power conversion system and controls will be provided by NEC Energy Solutions. The storage facility is expected to be completed by the end of this year.

Eneco and Mitsubishi stated that they will also start pilot energy storage projects where energy from locally produced wind projects will be stored.

Mitsubishi Corporation Group CEO Hiroshi Sakuma said: “We believe that energy storage will become a key factor, given the circumstance that energy volatility is expanding as the result of the rapid increase of renewable energy. This project is a significant step forward to the realisation of the sustainable society.”

Eneco Group chief strategic growth officer Kees-Jan Rameau said: “Although, fortunately, the share of sustainable energy is increasing rapidly, it does pose a challenge for the energy grid. In our view, the solution to this is twofold: smart matching of supply and demand and a combination of small-scale and large-scale energy storage.

“Last year, we initiated the creation of a network of home batteries for consumers. In collaboration with Mitsubishi Corporation, we are now also making significant progress in the area of large-scale sustainable storage. Germany is a frontrunner in green development and, as such, ideal for gaining experience. This step will also provide valuable knowledge that can be applied on the Dutch market.”
