Vattenfall's largest land-based wind farm, Pen y Cymoedd in South Wales, UK, is now supplying electricity at full capacity. The 228MW Pen Y Cymoedd wind farm has a total of 76 wind power turbines provided by Siemens.
A storage plant for generated electricity will also be built at Pen y Cymoedd (on condition that an investment decision is made by Vattenfall's Board of Directors). 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, are equipped with a BMW-owned battery control system.
