Situated on Dogger Bank, the Sofia wind farm will have one hundred 14 MW wind turbines with a total installed generation capacity of 1.4 GW.
Its commissioning is scheduled for 2025. The electricity generated will be transported to the British transmission network via a 220km-long HVDC line. Two HVDC-VSC General Electric converter stations will be built at both ends of the line.
RTE international has been brought in as a contractor to be an independent technical consultant and is working in conjunction with the project developer from RWE, the manufacturers of the system and the National Grid to enable this system to be integrated into the UK’s electricity supply.
