The 89-turbine project was initially due online this summer, but has now been pushed back to the third quarter of the year, Ventolines explained.
Installation of the wind farm’s 89 SWT-DD-130 turbines – each with an individual power rating of 4.3MW – began in spring.
To date 25 turbines have been installed in the lake next to the Afsluitdijk dam, on the northern shore of the IJsselmeer, and the remainder are due to be installed over the summer.
The turbines are being assembled on site aboard two vessels in the IJsselmeer. This is because narrow locks in nearby rivers mean full turbines cannot be transported to the site.
Construction consortium Zuiderzeewind – a partnership of Siemens Gamesa and Van Oord – has also reached a number of milestones for the project. Fryslân’s inter-array cables are in place. The connection with the Oudehaske high-voltage substation near Heerenveen – two 55km underground 110kV cables – has been put into operation.
To date, Fryslân has been supplying energy – though not the full project output – to utility Eneco.
