I'm not sure if that is the wind farm. Looking at the article photos, there are a lot of turbines in the area, so there is probably more than one wind farm adjacent to the coal mine. Even with Senvion out of business, it still feels far too early for them to be pulling down turbines - normally they have about 30 years' life in them before they're sold on to another country. However, the article also says they're only pulling down 7 turbines, so even if it is the same wind farm they're not fully dismantling it.

Edit: Actually I think you're right about the site. It looks like it might be these turbines they're pulling down, and I imagine the motorcross site could be included in the project also.
