TenneT has awarded the DolWin3 offshore project to Alstom. This project connects the North Sea wind farms to the mainland supergrid and has an investment volume of more than €1 billion.
Alstom will supply and construct both the onshore and offshore converter stations as well as the connecting cable systems for DolWin3. The project will use direct current technology (with Voltage Source Converters (VSC); ±320 kV, 900 MW) to deliver the energy generated at sea down an 83 km sea cable to the mainland. From the coast, the wind power will then be transported a further 79 km via and underground cable to the converter station in Dörpen/West in Lower Saxony (Germany). The grid connection will be supplied as a turnkey solution by Alstom. Together with the turnkey contract, Alstom has been awarded a five-year service contract covering the complete offshore converter station and platform, as well as the onshore converter system. The contract includes inspection, preventive and corrective maintenance, refurbishment and repair, spare parts management and a technology support line. The project will be completed in 2017.
