The company is first starting cable installation for the largely parallel running systems DolWin4 and BorWin4, which will connect offshore wind farms with a capacity of 1.8 GW in the North Sea to the power grid in the town of Lingen.

For the DolWin4, subsea cable installation in the Wadden Sea area and north of the Norderney island will take place in the coming months. Prysmian, the company contracted for cable manufacturing and installation, will begin setting up construction sites on the island from the beginning of May. This is possible after authorities granted permission for early construction start under strict environmental protection conditions, Amprion said.

The installation operations also involve work at the beach area of Norderney island, which is planned to complete in by the end of May or in early June.

After beach works are finished, the company will continue with the cable installations between the island and the mainland for BorWin4. The actual work is expected to begin in mid-August.

Amprion will also carry out in August horizontal drilling on the island for the BalWin1 and BalWin2 projects. The goal is to install protective conduits for future power cables.

BalWin1 and BalWin2 each have a transmission capacity of 2 GW. They are scheduled to enter operation in 2030 and 2031. Together they will cover the electricity demand of around 4 million people.

DolWin4 and BorWin4 are expected to become operational in 2028. They will allow 1.8 GW of offshore wind power reach the mainland, replacing the lost generation capacity of the former Emsland nuclear power plant, which was switched off in April 2023. Amprion initiated the construction of a converter station for DolWin4 and BorWin4 in May 2025.
