On September 28, Vattenfall`s largest onshore wind farm, Pen y Cymoedd in Wales, is inaugurated. The 228MW Pen y Cymoedd wind farm could also become the largest commercial wind farm in the world with a co-located battery facility for storing electricity.
In March, Vattenfall and the BMW Group signed an agreement for the supply of up to 1,000 lithium-ion batteries this year. The batteries, which have a capacity of 33 kilowatt hours (kWh) each, will be packaged and installed at Pen y Cymoedd in Q4 this year and deliver enhanced frequency response to National Grid hence help to integrate renewable energy to the energy system.
