Almere-based Alfen installed its 1 MWh battery storage solution at the 9 MW Giessenwind wind farm in the town of Giessenburg.
The firm also supplied a transformer substation and the grid connection.
Giessenwind consists of three turbines and powers around 5000 households. The storage system was commissioned this month.
Scholt Energy Services, which operates the windfarm, supplies power to businesses in Belgium, the Netherlands and Germany and plans to initially use the storage system for energy trading.
Sander Drissen, business development manager at Scholt Energy Services, said the installation “provides a sustainable basis for the future and can easily be expanded when necessary”.
“We are also looking at other locations and applications such as local grid stability,” he added.
Andreas Plenk, who is responsible for global energy storage system sales at Alfen, said the company is working on projects to connect its energy storage system directly to renewable energy sources.
