The power station was decommissioned on May 13, 2005, and the chimney demolished on Sunday, December 3, 2006, at 10:53 a.m.
It was the tallest structure in North Rhine-Westphalia. Before its erection the 320.8 m tall Wesel transmitter tower took this claim. After the demolition of the chimney, the Wesel tower once again became the tallest structure in North Rhine-Westphalia.
A district heating plant, "FWK Westerholt", has been in operation on this site since the spring of 2004. There are six boilers there to provide heat for the district heating network of the northern Ruhr Area.
The Westerholt coal mine is located only a few hundred metres away. Both the power plant and the mine are on the city limits of Gelsenkirchen in the Hassel neighborhood and were named for the contiguous (and at that time still independent) city of Westerholt in what was then the district of Recklinghausen (today the city is a part of the city of Herten and is named "Herten-Westerholt").
