Alfen delivers mega energy storage system for Nuon

Unfortunately, sometimes wind turbines cannot be used even though it is a windy day. The energy that is generated is more than the power grid can absorb and gets lost. This problem is now being solved at Nuon’s Prinses Alexia Windpark in Zeewolde, the Netherlands. Dutch company Alfen has developed a mega energy storage system by connecting a large number of BMW car batteries. The system stores the surplus of energy so that it can be used when the grid requires the power at a later moment in time.

Together with BMW and Nuon, Alfen launched its 3 MW storage system at the Prinses Alexia Windpark in Zeewolde on Wednesday 28 June. The system will be expanded to 12 MW over the coming period, making it the largest storage project in the Netherlands.

This is the second project that connects energy storage to a wind farm. In May this year, Alfen realized a 1 MW storage system linked to wind farm Giessenwind at Giessenburg.

With the project at Prinses Alexia Windpark, Nuon and its parent Vattenfall make an important step forward in realizing their sustainable ambition to be climate neutral in 2050. This will enable Nuon to make flexible use of renewable energy without wasting energy.

Nuon is looking further: for example, they are planning to install a battery in residential areas with many houses with rooftop solar. In this way residents can use their solar energy that is generated during the day to charge their car at night.
