Danish utility Dong Energy by the end of the year will link its 90MW UK offshore wind array Burbo Bank to a 2MW battery system on land, in an industry first designed to provide frequency response to the grid.

“The need for flexibility is expected to grow, and as a low carbon leader we're keen to be part of the solution to make the energy system smarter,” said Ole Kjems Sørensen, senior vice president, partnerships/M&A and asset management at Dong.
