Vattenfall has signed a contract with BMW Group for supply of lithium batteries which will be used for its energy storage projects.

As per the contract, BMW will supply 1000 batteries, each with a capacity of 33KWh, to Vattenfall this year.

According to Vattenfall, the the first battery storage project that will feature BMW-i3 batteries is being built at the 122MW Princess Alexia onshore wind farm near Amsterdam. With a capacity of 3.2MW, the project will be Vattenfall's first large storage facility in the Netherlands.

With final investment decision pending, Vattenfall is planning to build a massive storage project, with a 22MW capacity, at the 230MW wind farm Pen y Cymoedd in South Wales. The storage project is expected to offer stability across country-wide power grid in the UK.

As part of the Norddeutsche Energiewende NEW 4.0 project, Vattenfall together with the Hamburg University of Applied Sciences (HAW) and Nordex will develop battery facility at a wind farm that is expected to come up in Hamburg-Bergedorf.

Vattenfall senior vice president and Business Area Wind head Gunnar Groebler 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.

“The decoupling of production and consumption and the coupling of different consumption sectors are in the focus of our work."

Vattenfall Innovation large batteries project manager Daniel Hustadt said: "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.”
