Vattenfall is to buy batteries from BMW and use them in its energy storage projects.
The Swedish energy firm and German car manufacturer have signed a contract for the delivery of up to 1,000 lithium-ion batteries this year from BMW’s factory in Dingolfing.
Each one has a capacity of 33kWh and is equipped with a state-of-the-art management system – they are normally used to help power BMW’s i3 electric vehicle.
The first energy storage unit using the batteries is being built at the 122MW Princess Alexia onshore wind farm near Amsterdam.
With a capacity of 3.2MW, it is Vattenfall’s first large storage project in the Netherlands.
A 22MW installation is also planned for Vattenfall’s 230MW Pen y Cymoedd wind farm in South Wales.
The company says possible applications in the future include storing electricity in private households.
Gunnar Groebler, Senior Vice President of Vattenfall, said: “Energy storage and grid stability are the major topics of the new energy world.
“We want to use the sites where we generate electricity from renewable energies in order to drive the transformation to a new energy system and to facilitate the integration of renewable energies into the energy system with the storage facilities.”
Vattenfall has announced it is switching its entire fleet to electric vehicles over the next five years.
