The facility has 22 megawatts (MW) of installed capacity. The battery which shares electrical infrastructure with the Pen y Cymoedd wind farm, will help the U.K.'s national grid maintain frequency levels and reliability of electricity supply by storing electricity produced by the wind farm.
"The battery is made up 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 kilowatt-hours (kWh) supplied by BMW and adapted for a stationary application," the company stated.
The 76-turbine Pen y Cymoedd onshore wind farm is capable of meeting the equivalent electricity needs of more than 13 percent of Welsh households per 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 fueled generation," the company said.
