RWE has completed the installation of all 100  turbines at the Sofia Offshore Wind Farm, marking a key milestone in the construction of one of the UK’s largest offshore wind farms.

The 1.4 gigawatt (GW) site is located on the shallow central area of the North Sea known as Dogger Bank, and 195km off the UK’s North-east coast.

On site, testing and commissioning of the HVDC (High Voltage Direct Current) distribution system is also continuing before the turbines will be connected to the HVDC system.

The 100 turbines were installed using construction jack up vessel Wind Peak, owned by Cadeler and operated by SGRE. The vessel has been transporting and installing turbine components, six sets at a time, since March 2025.

Once fully operational, Sofia will be capable of generating 1.4GW of renewable electricity, enough to power approximately 1.2 million typical UK homes.
