Alstom SA, a French engineering services provider, has won a contract from TenneT, the Netherland-based electricity transmission operator, to build the onshore and offshore converter stations, as well as, the connecting cable systems for €1 billion ($1.3 billion) DolWin3 offshore wind project in Germany.
The 900MW project connects the North Sea wind farms to the mainland supergrid. Pursuant to the contract, Alstom will supply and construct both the onshore and offshore converter stations, as well as, the connecting cable systems for DolWin3.
DolWin3 is the eighth grid connection project to be implemented by TenneT using direct current technology. It 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 900MW.
Alstom has also secured a five-year service contract covering the complete offshore converter station and platform, as well as, the onshore converter system. It includes inspection, preventive and corrective maintenance, refurbishment and repair, spare parts management and a technology support line.
Alstom will work with platform constructor Nordic Yards and cable supplier Prysmian for the project, which will be completed in 2017.
