Sofia convertor stations
RWE has moved a step closer to the realisation of its 1.4 gigawatt (GW) Sofia Offshore Wind Farm with the selection of the preferred suppliers for the project’s high voltage direct current (HVDC) electrical transmission system.
A specially formed consortium of GE Renewable Energy’s Grid Solutions and Sembcorp Marine is set to supply the state-of-the-art system for Sofia, one of the world’s largest offshore wind farm projects, located on Dogger Bank, the shallow area of the central North Sea, 195 kilometres from the UK coast’s nearest point.
As the consortium leader, GE’s Grid Solutions will be responsible for the engineering, procurement, construction and installation of two HVDC converter stations capable of transmitting 1,400 megawatts (MW) of power at 320 kilovolts (kV). Innovative converter modules and a new high-tech control system have been deployed for Sofia. It will be the most powerful offshore converter station ever fabricated and will be installed at a point 220 kilometres from shore, so will also be the most remote.
