Swiss industrial conglomerate ABB has won an order to deliver a two megawatt (MW) battery energy storage system to support the integration and transmission of power from the Burbo Bank offshore windfarm, near Liverpool.
This will be the first time an offshore windfarm integrates such a storage system to stabilise the frequency of the grid in UK.
The 90 MW Burbo Bank offshore wind farm has been in operation since 2007 and is capable of supplying electricity for up to 80,000 UK homes.
The National Grid operates a frequency level of 50 Hertz (Hz) to ensure grid stability and quality of power supplies.
Grid frequency is dependent on the balance between power supply and load demand. Integration of large amounts of variable wind energy increases complexity from a supply perspective and can result in frequency variations that can affect grid supply and impact consumers.
