The use of electric car battery packs to create large energy storage projects is becoming increasingly popular.
Now, a new one made of BMW i3 battery packs is connecting to the UK National Grid and has become one of the largest to date.
The project is made of six shipping container sized units, five of which house 500 i3 BMW manufactured battery packs, which each have a 33 kWh capacity.
For a comparison, BMW delivered just over 500 i3 electric vehicles in the US last month. Therefore, it’s a significant portion of their battery pack manufacturing going to stationary energy storage.
The 22MW facility has been installed at Vattenfall’s Welsh onshore wind farm Pen y Cymoedd.
It shares the electrical infrastructure of the wind farm to create a hybrid renewable energy and storage asset.
