Swedish green energy firm, Vattenfall, has initiated the operations of its co-located battery, designed to store renewable wind power generated by its onshore wind farm Pen y Cymoedd (PyC) in the UK.

The 22MW battery is made up of six units the size of shipping containers, five of which are equipped with the 500 i3 BMW manufactured battery packs.

The battery storage facility makes use of lithium-ion batteries with a capacity of 33KWh, adapted for a stationary application.

Vattenfall aims to assist the national grid maintain network reliability and supply during times of peak demand, as well as provide support as increasing numbers of electric vehicles put pressure on the grid.

Aside from meeting power demand requirements, the storage facility will support Wales’s climate change goals, reducing carbon emissions from fossil fuelled generation.

The wind farm comprises 76 wind turbines and has the capacity to generate enough power to meet the electricity needs of more than 13% of households in Wales every year.

Vattenfall Wind Business Area senior vice-president Gunnar Groebler said: “Vattenfall is on the road to a smart, digitalised 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.”

Vattenfall Solar & Batteries Business Unit head 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.”
