German Transmission System Operator (TSO) TenneT has awarded the DolWin3 offshore project to Alstom. This DoWin3 project connects the North Sea wind parks to the mainland supergrid and has an investment volume of more than €1bn.
DolWin3 is the 8th grid connection project to be implemented by TenneT using direct current technology. Together with three projects based on AC current technology, the TSO responsible for the North Sea will then deliver a total of around 6.2 GW of offshore wind energy to the mainland. The DolWin3 project will be the third grid connection in the DolWin wind farm cluster in the south-western region of the North Sea and will offer a capacity of 900 MW. The project will be completed in 2017. As the general contractor for TenneT, Alstom will supply and construct both the onshore and offshore converter stations as well as the connecting cable systems for DolWin3.
