This was the largest thermal power station in Belgium.It has expanded over the years from two turbines to six to keep up with the demand of modern day living. Now it is being decomissioned.
It looks like it could be fired up into production immediately. I do in fact remember a very large Humming sound coming and going through out my visit. However I forgot to investigate the sound further. Maybe this was for the best. I loved the symmetry here and did get drawn to it quite a lot as you can see.
