Vattenfall and the BMW Group have signed a contract for the delivery of up to 1,000 lithium-ion batteries this year. The batteries will be deployed for storage projects at Vattenfall wind farms. With a capacity of 33 kilowatt hours (kWh), each one is equipped with a BMW-owned battery management system and are also used by the car manufacturer in the BMW i3.
“Energy storage and grid stability are the major topics of the new energy world,” says Gunnar Groebler, Senior VP of Vattenfall and Head of Business Area Wind. “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 will purchase the new batteries from the BMW plant in Dingolfing, and use them in all future storage projects. The first energy storage from the BMW-i3 batteries is being built at the 122-MW Princess Alexia wind farm near Amsterdam. With a capacity of 3.2 MW, it is Vattenfall’s first large storage project in the Netherlands.
Pending on a final investment decision, the largest battery storage will be built at the 230-MW Vattenfall wind farm Pen y Cymoedd in South Wales. It will include a 22-MW 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.
As part of the project “Norddeutsche Energiewende NEW 4.0,” Vattenfall, together with the Hamburg University of Applied Sciences (HAW) and the company Nordex, will implement a large battery storage at the future wind farm in Hamburg-Bergedorf. This is a storage control unit made of batteries. It is meant to maintain the security of supply with a feed-in of 100 percent renewable energy.
In addition, the battery storage contributes to the improvement of the network quality and the more efficient use of the existing network structure. Other possible applications would be electricity storage in private households. Energy storage solutions are an important part of Vattenfall’s strive to power climate smarter living.
“We are pleased that we have found a supplier in BMW, who meets our high safety requirements with the use of the batteries with reliably good quality from German series production,” said Daniel Hustadt, Project Manager for large batteries at Vattenfall.
