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?

The demolitions are part of a deal brokered last year between Robert Habeck, the Green party's minister for economy and climate action and Mona Neubaur, who is the economy minister for North Rhine Westphalia, to allow the expansion of the mine.

In return, RWE had to agree to phase out coal in 2030, eight years before the previous deadline. "It's a good day for climate protection," Habeck said at the time.

What’s the timeline for getting this expansion built? And what’s the lifecycle of the plant? I understand there are energy scarcity concerns, but how is this the most economical option when it’s ~7 years until they’re supposed to phase out coal?

The wind turbines are already at the end of their lifespan and they knew RWE had the license to expand the mine there when the wind turbines where build.

Of course it's economical for RWE, they are not building a new mine. Just continuing their mining operation there for another 7 years.

"We live our life one quarter ~~mile~~ at a time" - RWE probably

I mean, that's probably actually it. Short term profits are all shareholders care about. We've seen that time and time again where businesses will absolutely mutilate themselves just so shareholders can enjoy a short term price spike. This is just a pump and dump but for the energy industry.

Most likely they have no intention of stopping coal production and will just move the deadline again in 2030 and no one will do anything about it.

That's possible, particularly if different parties are in power at that time. However the article also notes that lignite is becoming less economically viable and may need to be wound up anyway in 2030.

I'm guessing their bracing for winter without Russian oil. Which will hopefully be transitory, but also sort of delays the inevitable. If they can't survive a winter without fossil fuels they need to figure it out quick.

This expansion is the last one although actually many more in the next decades were already approved and contracted, which got renegotiated with the energy companies. But of course this was already mispresented earlier this year when everyone reported on Germany destroying the village of Lützerath for their newly started coal digging when it was actually the last one (with half a dozen more similiar small villages originally scheduled for destruction more than a decade ago). But lobbyists pay to push lies and publications love the clicks for the popular outrage about evil Germans. Who cares for facts, anyway...

Those wind power plants were originally build with the knowledge that they have to be disassembeled in less than a decade again. Also those models proved to be very problematic and the company building them went out of business after only 4 years (since then there was only some auxiliary technical support from other companies).

Counter question: How economical is it to stop digging up coal today when the phase-out is 7 years away. They can either increase the pit or dig deeper. The latter is not only more expensive but also more damaging (pumping groundwater away from the hole etc.).

PS: A decade is also the usual life time of a wind power plant nowadays... After that time the gear boxes and blades need to be replaced and the foundation needs to be checked because of constant micro vibrations... In theory the installation itself could run up to 30 years but the technical development is still moving ahead so fast that replacing the whole thing with a newer and more efficient (also often bigger) model usually makes more sense than replacing parts to keep them running. So for now wind turbines are rather short-lived as their replacements see constant substantial improvements.
