German energy giant RWE has begun dismantling a wind farm to make way for a further expansion of an open-pit lignite coal mine in the Western region of North Rhine Westphalia.

I thought renewables were cheaper than coal. How is this possible?

    So, if I’m reading this correctly, this is the Konigshovener Hohe wind farm which is built on the site of the Garzweiler open-pit lignite mine. According to this article, the site was inaugurated in 2015 with 21 Senvion turbines.

    The problem is, Senvion went out of business in 2019, and customers have been struggling to support their turbines. Apparently the Senvion design is exceptionally dependent on software access. Siemens and others have stepped in to offer support contracts to Senvion turbines in good working order, but with the opportunity to mine more lignite at the site, maybe RWE felt that it was time to spin down the Senvion turbines.

    It seems like there may be many factors in this decision.

      Thanks for providing this context. From what you say it sounds like a bad initial decision from RWE - tieing themselves in to 'wind turbine as a service’doesn’t seem sensible.

      We should be using open source solutions for things like energy security. It’s not like our civilization can run without energy generation. The control ought to be in the hands of people, not corporations.

      I’m not sure that’s the right wind farm. According to this guardian article, it’s actually the Keyenberg wind farm that’s being dismantled, a retired site from 2001.

      Apparently the site is retired because the operator’s permit ends in 2023. Making way eventually for the mine expansion was part of the original deal allowing the land to be used for wind turbines, and so it’s not indicative of any change in climate policy from the German government. Additionally the turbines are somewhat outdated, having only a sixth of the power output of a modern one. They would have to tear down and modernise the turbines anyway even if not for the mine.

      However from a publicity standpoint it’s not an ideal move. Could have given up on the lignite and put new wind turbines in instead, perhaps.

      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.

        Yeah, but look up the story on the Senvion turbines. Basically, Senvion operators have had to pay big money for service contracts with 3rd parties since Senvion went out of business.
