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.
