Alfen delivers a mega energy storage system for Nuon (complete with BMW i3 batteries)
Dutch company Alfen, has delivered a 3 MW energy storage system for Nuon’s Prinses Alexia Windpark in Zeewolde, the Netherlands.
What we find interesting with this installation, is that the energy storage system (ESS) consists of multiple BMW car battery packs, that combine to store any surplus of wind energy, so that it can be used when the grid requires the power at a later moment in time.
"The Alfen mega energy storage system helps to smooth peaks and troughs in power supply and better match the demand for energy. In this way we are creating more flexibility and stability in the system to facilitate renewable energy."
In the near future, the system will be expanded to 12 MW, becoming the largest in the Netherlands and one of largest worldwide (Tesla's largest installation in Australia is to be 100 MW in another ~100 days or so).
Earlier this year, Alfen realized a 1 megawatt storage system linked to a wind farm in Giessenburg, so the scale is moving up quickly.
"This will enable us to make flexible use of renewable energy without wasting energy. And we are looking further: for example, we 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. Today this is still happening with energy from fossil fuels."
"Our system is compatible with multiple batteries. The excellent collaboration with both Nuon and BMW has made it possible to realize this innovative system in a short period of time. In addition, the installation has a modular set-up which makes it easy to expand in the future."
