Vattenfall installs 20MW BESS at UK wind farm site

October 12, 2023

Vattenfall has installed a 20MW, two-hour battery energy storage system (BESS) next to its 16-turbine Ray Wind Farm near Otterburn in Northumberland England. 

Owned and operated by Vattenfall, ‘Battery@Ray’ could meet the electricity demand of 3,500 UK households for 24 hours.

The wind farm has been operating for more than six years and produces around 10 per cent of Northumberland’s energy needs. 

“Co-locating the battery at Ray Wind Farm enables the production of electricity to be more cost effective by sharing infrastructure, such as the roads around the site and the electricity grid connection,” a Vattenfall statement said.

Ross Williams, project manager at Vattenfall, said: “Battery projects were in their infancy when Ray Wind Farm first started generating fossil-fuel free energy. Since then, battery technology has advanced, and I’m delighted that Battery@Ray is now energised and helping towards our ambition of fossil-free living.

“Ray is a great example of how we can unlock the environmental and economic benefits of renewable energy. Local and regional solutions for storing and using electricity, are becoming increasingly important, as the UK moves to net zero and our electricity requirements increase. Projects like Battery@Ray are the missing piece of the jigsaw, providing a solution here and now.”
