The contract for RWE to expand the mine there goes back decades and the wind farm operator knew it would be demolished before they build it. It's at the end of its life cycle now and had to be demolished one way or another.

German government could either breach their contract with RWE and pay them compensation or allow the destruction of a derelict wind park in exchange of RWE stopping coal extraction 8 years earlier then planned. It's a job well done by the government.
