A lot of big energy-consuming events, such as concerts, football games, etc, are held at Amsterdam’s Johan Cruyff Arena. The needs for energy are huge when people get together for the big events. Therefore, the energy grid will have more press than usual.

The system combines power conversion units and the equivalent of 148 new and used Nissan LEAF batteries, which store energy captured by 4,200 solar panels on the roof of the stadium and also from the grid.

It is capable of storing 3 megawatts of power – enough to charge 500,000 phones or supply 7,000 households in Amsterdam for one hour – and its makers say it’s Europe’s largest commercial energy storage system using EV batteries.

This system provides a reliable source of sustainable energy, but it also relieves pressure on the Dutch electricity grid during concerts and other big energy-consuming events. And during periods of low demand, the stadium can contribute power to the grid.
