Vattenfall unveils co-located 22-MW battery

Vattenfall’s battery@pyc, the largest co-located battery installation in the United Kingdom, is now operational, storing renewable wind power from the company’s Welsh onshore wind farm Pen y Cymoedd.

The 22-MW facility, which shares electrical infrastructure with the Pen y Cymoedd wind farm, will help the UK National Grid maintain frequency levels and reliability of electricity supply by storing electricity produced by the wind farm, said Gunnar Groebler, senior vice president, Business Area Wind. “Vattenfall is on the road to a smart, digitalized future, free from fossil fuels. I can think of few other energy installations that better demonstrate what that future looks like than this battery installation,” he said.

The battery is composed of six shipping-container-sized units, five of which house 500 i3 BMW manufactured battery packs. It uses new lithium-ion batteries with a capacity of 33 kWh supplied by BMW and adapted for a stationary application.

“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,” Claus Wattendrup, head of Business Unit Solar & Batteries, said. “Hybrid renewable parks will play a larger role in the future, and we are leading this development.”

The 76-turbine Pen y Cymoedd onshore wind farm is capable of meeting the equivalent electricity needs of more than 13% 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 tons of CO2 from fossil-fueled generation.
