Vattenfall moves Vesterhav turbines

This story first appeared in our subscriber exclusive offshore update, earlier this week.

Vattenfall has unveiled its new design for the 350 MW
Vesterhav Nord & Syd offshore wind project, with turbines to be positioned further from the coast.

Vattenfall has had to re-design its turbine layout and produce a supplemental Environmental Impact Assessment (EIA) for the project after the Danish Energy Board decided to revoke the project permits in late 2018. In the new draft documents the 20 turbines in the Syd area will be located 9 km offshore, which doubles the distance compared to the wind turbines closest to the coast in the original design.

Turbine layout in the Nord area has also been revised to maximise the distance of the 21 turbines from shore. Vattenfall hope to complete the EIA this summer after which the DEA will launch a public consultation. The project is now due online by 2023 after the DEA granted a three extension to the commissioning deadline.

Despite delays to the wind farm, Energinet nears completion of the onshore transmission system. Work has included the construction of two new substations at Engbjerg and Søndervig and ~83km of 150 kV cabling to connect to the Danish grid. Cabling was supplied by LS Cable and installed by Per Aarsleff. Electrical components for the substations were supplied by GE, Getra, Siemens and BESTtrafo with Kaj Bech and Caverion undertaking the substation construction work.

Energinet stated that the system is now energized and almost all construction works are finished.
