Butendiek substation set to sail

The offshore substation built for WPD’s 288MW Butendiek wind farm has been loaded out for transport to the development off Germany.

Designed and built by Belgian contractor CG, the high-voltage AC platform will be piled in at the site, located 32km off the island of Sylt in water depths of 19-22 metres, for connection to the TenneT-operated grid via the SylWin cluster.

Avantha-owned CG is delivering and integrating power transformers, high- and medium-voltage switchgear, and auxiliary reactors and transformers to tie together the 33kV and 155kV networks at Butendiek.

The installation includes a low-cost, lightweight AC/AC connection link for offshore wind farms, already in use at the North Sea Belwind and Northwind developments, designed to need less maintenance than conventional high-voltage AC/DC solutions.

Butendiek, which is built around 80 Siemens 3.6MW turbines, is expected to supply energy to 370,000 households.
