DONG Energy has announced plans to offer frequency response from its existing Burbo Bank Offshore Wind Farm using a combination of wind power and battery. The addition of the 2MW battery system, set to be installed by the end of the year, will enhance the capability of the 90MW wind farm.

It will be the first time an offshore wind farm is integrated with a battery system to deliver frequency response to the grid. Frequency response is a mechanism used by National Grid to help manage grid stability. Combining a battery system with a wind farm can provide fast and less costly frequency support. The 2MW battery system will be supplied by ABB. Burbo Bank Offshore Wind Farm has been fully operational since 2007.
