Vattenfall’s battery storage project will support the Pen y Cymoedd wind farm
Swedish energy group Vattenfall has installed 500 i3 BMW manufactured battery packs as part of a battery storage scheme in the UK.
The 22-MW battery@pyc project shares electrical infrastructure with the Pen y Cymoedd onshore wind farm in Wales. The batteries are stored in five units the size of shipping containers.
The batteries will help maintain frequency levels and the reliability of supplies on the UK’s transmission network with a service known as Enhanced Frequency Response.
“Vattenfall is on the road to a smart, digitalised future, free from fossil fuels within just one generation. I can think of few other energy installations that better demonstrates what that future looks like than battery@pyc,” said Vattenfall head of business area wind Gunnar Groebler.
Head of business unit solar and batteries Claus Wattendrup said: “This is Vattenfall’s largest battery installation to date, where we make use of synergies at our existing wind farms sites – such as at Pen y Cymoedd or the Princess Alexia Wind Farm in the Netherlands. Hybrid renewable parks will play a larger role in the future and we are leading this development.”
Battery@pyc will use new lithium-ion (Li-ion) batteries with a capacity of 33 kWh supplied by BMW and adapted for a stationary application.
The 76-turbine Pen y Cymoedd onshore wind farm is capable of meeting the equivalent electricity needs of more than 15% of households in Wales every year. It also boosts delivery of Wales’s climate change ambitions, displacing in an average year more than 300,000 tonnes of CO2 from fossil fuelled generation.
