VATTENFALL BUYS BMW BATTERIES FOR WINDFARMS

Energy storage Batteries from the German car manufacturer to enhance grid stability.

Vattenfall and the BMW Group have signed a contract for the delivery of up to 1,000 lithium-ion batteries.  The 33 kilowatt hour batteries are normally used in BMW’s electric i3 model. By stacking batteries together, Vattenfall will be able to use them for power services purposes.

"Energy storage and grid stability are major issues in the new energy world", says Gunnar Groebler, Head of Business Area Wind. "We want to use sites where we generate renewable energy in order to drive transformation of the energy system.”

The first energy storage from the BMW batteries is being built at the onshore wind farm "Princess Alexia" near Amsterdam. With a battery capacity of 3.2 megawatts, it is Vattenfall's first large storage project in the Netherlands.

Pending on a final investment decision, the largest battery storage is planned for the Vattenfall wind farm Pen y Cymoedd in South Wales: a 22 megawatt storage facility, which will help to support the stability of the country-wide power grid in the UK as part of the so-called EFR (Enhanced Frequency Response) service.

A third battery storage facility is planned for the future wind farm Hamburg – Bergedorf.

"We are pleased that we have found a supplier in BMW who meets our requirements on batteries with high and reliable quality,” says Daniel Hustadt, project manager for large batteries at Vattenfall Innovation GmbH.

The batteries are so called High Voltage Systems, HVS and are manufactured in BMW’s plant in Dingolfing in Bavaria.
