Retiring Worn-Out Wind Turbines Could Cost Billions That Nobody Has (energycentral.com) 574

schwit1 shared this article from Energy Central News: Estimates put the tear-down cost of a single modern wind turbine, which can rise from 250 to 500 feet above the ground, at $200,000... Which means landowners and counties in Texas could be on the hook for tens or even hundreds of millions of dollars if officials determine non-functional wind turbines need to be removed. Or if that proves to be too costly, as seems likely, some areas of the state could become post-apocalyptic wastelands steepled with teetering and fallen wind turbines, locked in a rigor mortis of obsolescence.

Companies will of course have the option of upgrading those aging wind turbines with new models, a resurrection of sorts. Yet the financial wherewithal to do so may depend on the continuation of federal wind subsidies, which is by no means assured. Wind farm owners say the recycling value of turbines is significant and recovering valuable material like copper and steel will cover most of the cost of decommissioning... Yet extracting valuable materials from the turbines is not as easy as it sounds... "The blades are composite, those are not recyclable, those can't be sold," said Lisa Linowes, executive director of WindAction Group, a nonprofit which studies landowner rights and the impact of the wind energy industry. "The landfills are going to be filled with blades in a matter of no time...."

Unlike Duke Energy, some of the smaller wind farm companies operating in Texas, with fewer financial resources, may be tempted to just walk away when aging turbines no longer spin a profit. Linowes believes such moves may begin occurring even before wind turbines outlive their useful life as manufacturing warranties on the big turbines expire. "At what point does the cost of maintenance tip over to the point it's not worth maintaining a turbine?" she said. "We're in something of an unknown or uncertain territory... It could be a very ugly situation in the next five years when we see turbines need work, and are no longer under warranty and not generating enough electricity to keep running them."

      Centrally planned economies and government subsidies often go horribly wrong in all kind of unintended ways. Let's stop subsidizing anything instead of thinking ourselves wise and just spending the subsidies elsewhere. It sounds good in theory, but once you legitimize a practice you have to remember that some of the people who will be deciding what to subsidize in the future will not sure your beliefs or may be quite opposed to them.

      I don't know whether this is an actual issue as opposed to some anti-wind hit piece, but there's a much easier solution assuming that this is an actual problem. Add the cost of the eventual decommissioning into the tower when it's being constructed. If that makes it completely unviable financially then amortize the cost over the lifetime of the tower and have part of the turbines production be set aside to pay for its decommissioning.

          The problem is that neoliberal free market capitalism isn't exactly delivering flowers and unicorns in many situations either.

          I'd argue that it's enriching the rest of the world at an alarming rate. Since China and India moved towards market economies, poverty has been eliminated at a staggering rate. I think the problem is that people like to compare the reality of free markets to the utopian promise of collectivism. Free markets don't look appealing because they only promise that total wealth generated will tend towards the maximal, not that everyone will be wealthy. Marxist doctrines always promise a great equity, but when you look at the results it fails utterly. It's not that the idea itself is bad, but it won't work for human beings due to our nature.

          If you want to account for negative externalities, you need to make sure that there's someone who actually owns those things which will suffer negative externalities. Having the government do it doesn't work as they're not as good at caring about environmental damages as an individual person is. As bizarre or counter intuitive as it might seem its a better system in practice. A great example is private hunting operations in Africa that do a better job of conserving wildlife and protecting it from poachers. When your livelihood depends on an animal, you'll spend much more of your effort protecting it. A government will continue to exist whether or not the animal lives or dies.

          but throwing one's hands in the air and saying we just have to sit around and let the invisible hand slap us repeatedly in the face is just a form of ideological fundamentalism.

          People have some kind of view of "the invisible hand" as some kind of sky fairy or omnipotent presence like its the god of capitalism. It's none of those things. It's like the description of how the internet interprets censorship as damage and routes around it. We understand that the internet isn't some conscious being making that choice. Rather it's the result of individual people acting in a certain way. In this case, the invisible hand is a whole bunch of individual people all trying to act in their own best interests to get what they want. If you want the market to do something, you need to get the individual people playing in it to all (or in large) want something. Outside intervention to the contrary is treated as damage that people route around in one way (black markets being an easy example) or another.

And considering the cost of larger replacement turbines a new company would likely pull down the old turbines just to get the rights to the area.

          And all of this bullshit about wind needing tax subsidies when the fact is this is not true any more, wind is the cheapest form of power and in the future it'll still be the cheapest form of power even with energy storage added in.

      Agreed. Pretty much every wind farm I've seen has nothing else around it for hundreds of feet, so just put some explosives at the base of the tower and down it comes. Then chop it up and send it off for recycling - seems very unlikely that you couldn't turn a profit that way. Gets a little more expensive if you need to avoid hitting other windmills, but odds are that all the windmills in a given farm are going to be decommissioned at about the same time.

      I had a big wind company who spent years courting me. They wanted to put 24MW of 400' tall wind towers on our farm's mountain ridge lines. We're in an ideal location at the end of a funnel of mountains. But, in the end I said no.

      1. Their business model was based on the energy credits, not based on generating power. I only would get paid for power generated. Their presentation was grandiose but I'm good at math and the reality was I was going to see very little income from the project.

      2. The turbine blades would throw ice 1,000' in an arc down wind covering extensive portions of my farm and forest. This ice would damage the trees I raise and endanger the lives of myself, my livestock dogs and my livestock as well as damaging my buildings and fences. They accepted no responsibility for this risk.

      3. I asked them about end-of-life provisions and insisted that they setup a fund for decommissioning the system at the end of the 25 year lease or if they went out of business. They refused. They claimed that at the end of that time I would have very valuable equipment. I disagree.

      I declined to work with them for these three reasons. I'm very pro green energy and all that good stuff. I farm organically. But the wind towers have too may problems, at least with how they were proposing.

        • Fatigue life of the tower [researchgate.net] is typically around 40 years or so... You'll need to tear it down and start again at that time. So if you get 25-30 years out of a tower, and it's time to retrofit, it is probably cost-effective to bring the whole thing down and start from scratch, rather than retrofit the blades and generator and then have to demo the entire thing in half the life-span of the new components.

The article makes it sound like a wind turbine is a one piece thing, and when it dies, you have to decommision it. The truth is there are a few main components that need replacing to repower it, and that cost isn't that much more than their estimate of decomissioning costs. Nobody is decommisioning wind farms. Even if they were, the total cost of decommisioning every turbine in the nation (at TFA's exaggerated cost) is less than decomissioning one nuclear plant.

They do this regularly despite clauses in the lease that require them to remove old equipment at their cost. The companies know that relatively few landlords will sue them for the cost incurred by the landlord to have the equipment removed themselves.

      The difference is that those plants eat up shoreline, which is usually expensive, and there's an economic reason to tear them down and re-purpose them for other uses that can generate revenue. Wind farms are in big fields that are often already used for other things, or on hills that can't be used for much else.

    But we do not tear down and replace a building or a hydroelectric dam merely because it is old.

    Yes, repairs are costly, But the tear down cost is $200,000, then guess what, repair becomes a better option.

    I think most wind turbines will end up being repaired multiple times, probably once every 10 years or so. But their lifespan, including repairs will probably be in excess of 50 years.

    Note, the repair business will also mean that when we tear down the ones that really can't be repaired, those expensive composite blades will be checked, and if in good condition, used to cheaply repair other turbines whose blades failed. They will end up stockpiled, just like airplane parts, not dumped.

    the maintenance costs are not properly calculated... which is why despite being told repeatedly that this tech is economically competitive, no private money wants to invest in it absent heavy public support as an investment. Sure, companies might build solar or wind as a publicity or good will campaign move... but to make money?

    To be very clear, I want renewable energy to be competitive and efficient and for it to replace most of our grid power.

    Appreciate what I just said there.

    I want that.

    But... if we are to do things responsibly and sustainable then it is very important to not lie on the funding proposal sheet. It may get us to build more things in the short term but it will reduce trust in future proposals and will incline programs that could have been successful to fail because problems could not be addressed early.

    In effect, the people pushing this stuff past its legitimate place are sabotaging future more ambitious projects. If the maintenance costs are 50 percent higher than we were initially told, then we need to know that so that we can alter the plan to avoid that problem.

    Maybe some wind turbines are better for that then others. It depends. Its something we have to do... put it all in an excel spread sheet and go through a few different scenarios.

    What bothers me about these projects is that people believe so much in the "the cause" that they feel they have to lie about the numbers.

    You're not helping when you do that. Please stop lying. We can afford to build these things at a loss. And we often go into these projects with our eyes open that it isn't the most economical option. That's okay. But if you lie about the numbers on top of that then it makes everyone very suspicious, nervous, and generally avoidant regarding these projects.

    Which is funny. This statement is what they say, you can go to the web site and find it. But when you do, you will find that this same page also states that the entire purpose of the group is...

    "to counteract the misleading information promulgated by the wind energy industry and various environmental groups."

    Ah. And when you poke about a bit more, you'll learn that the Group was formed "by Jonathan S. Linowes, a self-proclaimed Tea Party activist and climate change denier."

    Linowes, as in the husband of the person writing the article, as in the founder and co-founders.

    So yeah, once again total BS gets onto the front page of /. Thanks fact checkers!

Keep up the good work! But please don't ask me to help.
