TenneT awards offshore grid connection project DolWin3 to Alstom.
Third grid connection in the DolWin cluster with a capacity of 900 MW.
Connection with new DC technology over a distance of 162 km.
TenneT connects 6.2 GW of Offshore wind energy, already meeting more than half of the German government’s goals (11 GW until 2022).
Transmission System Operator TenneT has awarded the DolWin3 offshore project to Alstom (Paris:ALO). This project connects the North Sea wind farms to the mainland supergrid and has an investment volume of more than ?1 billion. “With this project, we help to take the energy turnaround another step forward and make it possible for offshore wind energy to make an important contribution to our future energy supplies”, says Lex Hartman, member of the board of TenneT. “With DolWin3 included, we will be able to supply a total of more than 6,000 MW of clean energy from the North Sea – and we will be investing more than ?7 billion in the energy turnaround.”
DolWin3 is the eighth grid connection project to be implemented by TenneT using direct current technology. Together with three projects based on AC current technology, the Transmission System Operator 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.
“For DolWin3, TenneT will benefit from Alstom’s advanced technology. As market leader for offshore AC substations and onshore HVDC, we are well positioned to enter the German offshore HVDC market as a new competitor. The collaboration with Nordic Yards and Prysmian, who both have outstanding references, is key to delivering this turnkey contract,” says Gr
