Intermezzo: Belgian windfarms and the construction of one

Hi everybody,

Today I would like to deviate a little from the current debate about nuclear energy and die energiewende, while searching deredactie.be I found a short clip in wich they explain (briefly) how an offshore windfarm is build.


Seen as the clip has aired in april 2011, I did a bit of research to find out more about the progression of the project.

The project is situated on the Thorntonbank in the north sea. The Thorntonbank is a sandbank in front of the Belgian and the Dutch coast and is 25 meters higher than the surrounding seabed and about 20 km long.


The project started in 2002 and is/was divided into three parts


As you can see on the scheme the project is nearing its end, on the website of C-Power I found that they are expecting that the final phase will go into operation in september 2013.

The goals for the different phases are listed below


On this map you can spot the layout of the windfarm (the color of the windmill matches with the colors of the phases given in the scheme above)


The annual generation of the windfarm is about 1000GWh, this should be enough energy for the annual consumption of 600 000 people.

Seen as the first clip doesn’t really go into details, the following video is interesting to watch.  It provides more details about the different steps in the construction.


The phase 2 windmills on the pillars that where seen in the first and second movie clip.

Phase II windturbines

The windmills of the first phase where not fitted on this type of pillars


And it is certainly good to know that this not the only company interested in Belgian offshore energy production but that there are a lot of other company’s also active in the North sea.  The Belwind windfarm is already operating since 2010 and has an output of 550GWh.

Thank you for reading and let me know what you think about these Belgian projects!
