Dong Energy is to integrate a 2MW battery storage system into its 90MW Burbo Bank offshore wind farm in Liverpool Bay.
The battery, which will be the first of its kind at an offshore wind farm, aims to provide frequency response to help keep the grid stable, Dong said.
The battery, which will be supplied by ABB, will be installed by the end of the year.
Dong said frequency response is a mechanism used by National Grid to help manage grid stability close to 50 hertz (Hz).
“If the frequency was to deviate from these limits, it would affect everything plugged into the grid, from home appliances to power stations,” the company said.
The ability to inject or reduce bursts of active power allows the grid to rapidly respond to changes in frequency, it added.
National Grid head of network capability (electricity) Richard Smith said: “I’m looking forward to seeing how the Dong Energy solution of storage connected to the offshore wind farm will provide services to help us respond to day-to-day operational challenges and maintain the frequency of 50Hz on Great Britain’s electricity system.”
Dong senior vice president, partnerships/M&A and asset management Ole Kjems Sørensen said: “With eight existing offshore wind farms in the UK and another four under construction, we expect to leverage further technology improvements and innovations and ensure that Dong Energy supports the stability of grid systems as generation capacity becomes cleaner and more sustainable.”
Dong will present the solution later today as part of its R&D conference at Offshore Wind 2017 in London.
