Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, how many offshore wind turbines were installed at locations within (a) UK territorial waters and (b) the UK Exclusive Economic Zone in each year between 2017 and 2023.

The Crown Estate’s Offshore Wind Report 2023 states there were 2,776 operational offshore wind turbines in UK waters at the end of 2023.

The Department does not hold data on the number of installed turbines over time or whether they are located in UK Territorial Waters or the UK Exclusive Economic Zone, but does publish estimates of total installed generating capacity. These show that capacity grew by 7.8GW between 2017 and 2023.
