When wind turbines are no longer useful: They get explosive demolition

Video follows.

Controlled Demolition, Inc. (CDI) of Phoenix, Maryland, USA (acting as Explosives Design and Performance Subcontractor to Main Demolition Contractor, Dallas Demolition of Houston, Texas who was working for RiverCap Ventures of Rocky River, Ohio, the General Demolition Contractor) performs the successful explosives felling of 90, Mitsubishi 1000A Wind Turbines in New Mexico.

No effort was made to preserve foundations or other wind farm infrastructure. CDI’s crew felled the 90 Units in two (2) mobilizations to the site, permitting the Wind Farm Owner to complete salvage of blades and drive-train elements from some of the wind turbines to provide replacement parts for similar Units they operate at other wind farm locations. The Units were safely felled, exactly per plan, and ahead of schedule.

Modern life cycle on low volume, high tech stuff is less than 20 years, no matter what it is. Nobody wants to be on the hook for storing the spares inventory. For things meant to “last 25 years” without spares, its even worse, because when spares are needed, there aren’t any, and the OEM has moved on.

Blow it up and repeat the cycle.

Are they going to replace the windmills with new ones, or will there be 90000 tons of concrete left dotted around the landscape?
Presumably all the copper wire connections to the grid will have some use/value?
They will have to be quick before the local villains cotton on and nick it.
In all it would remind me of the concrete bases from derelict WW2 A-A and radar sites left on some heathland where I grew up.

Green energy (wind and solar) requires almost 100% spinning reserve, due to intermittency. That is why it is uneconomic energy nonsense.
https://wattsupwiththat.com/2018/11/16/stacking-concrete-blocks-is-a-surprisingly-efficient-way-to-store-energy/#comment-2520849

Here’s an even better solution:

1. Build your wind power system.
2. Build your back-up system consisting of 100% equivalent capacity in gas turbine generators.
3. Using high explosives, blow your wind power system all to hell.
4. Run your back-up gas turbine generators 24/7.
5. To save even more money, skip steps 1 and 3.

Reply to  Eric Vieira
May 23, 2021 8:27 am

You are correct Eric – wind power was always a mandate-and-subsidy scam.

Do you know that wind power gets “first access” to the grid, and reliable, dispatchable, cheaper gas turbine power is routinely backed off to make room for the wind power? Could any idea be more absurd? Scam.

Now add to that the fact that increased atmospheric CO2 is not causing dangerous global warming. Scam x Scam = Scam^2

Now add to that the high probability that the cause of increased atmospheric CO2 is primarily natural, not man-made. Scam x Scam x Scam = Scam^3

Dave Burton
Reply to  ALLAN MACRAE
June 5, 2021 5:09 am

All correct except the last paragraph, Allen. There is zero probability that the cause of increased atmospheric CO2 is primarily natural.

Nature is a net REMOVER of CO2 from the atmosphere. We know from measurements that that has been the case every year since at least 1958. Mankind’s CO2 emissions are currently about double the rate at which nature removes CO2 from the atmosphere, but as mankind’s emissions decline, that will no longer be the case.

Nature’s accelerating removal of CO2 from that atmosphere is a looming problem, because it means that when mankind’s CO2 emissions decline by more than about half, the atmospheric CO2 level will begin to fall, with negative consequences for agriculture. If mankind’s CO2 emissions dropped to “net zero” then the atmospheric CO2 concentration would fall precipitously, which would be a slow-moving but ever worsening disaster for mankind and nature.

I’m sure all those “green” windmill blades use carbon-free plastics. (Probably made from recycled carbon free tires.)

June 5, 2021 5:21 am

If they didn’t have so much glass in them, you could presumably grind them up and add them to the fuel mix for coal-fired power plants. However, I suspect that the fiberglass content makes them unsuitable for waste-to-energy tech. (I’d like to be wrong!)

If you can find the original leasee. Many in the US are corporations with tangled foreign ownership that quickly go bankrupt after subsidies run out.

The only resort is an upfront bond.
We wrote that provision into our NYS town’s ordinances as wind sites crept up from PA to the Finger Lakes.

The encroachment of our beautiful ridges stopped on on small town immediately south of us. There is no way of knowing if the bond requirement stopped them or even if the NYS government, who favored those developments, would have allowed our provision to stand, push come to shove.

The coolest way to explode a wind generator is to turn the governor off. The blades will overspeed in high winds, the tips will break the sound barrier and the resulting asymmetrical loads on the airfoils results in an immediate and dramatic “explosion”.

May 22, 2021 3:59 pm

I would guess that few wind turbines would reach their 25 year life expectancy. Typically they only break even in terms of emissions and energy at the 15 year mark, based on rosy predictions, so they only have a 10 year period of making an energy profit, something most do not achieve.
The costs of removal of the defunct edifices to monumental stupidity are never factored in to the monetary, carbon, and energy budget of wind power, let alone the environmental damage. They subsidy farmers just whistle and turn a blind eye to the long term environmental damage. Even the concrete foundations diminish the amount of farm production long term. I will bet that the hundreds of years of lost growing capacity were not factored in to the business model. Perhaps the wind power producers need to continue to pay off the farm owners for the lease of their land until they make good- remove the foundations and roads.
Never mind, all these inconvenient costs are bankrolled by subsidies paid by the taxpayers.
I propose a change in name from wind farms to subsidy farms.

I presently live in the Phoenix area ten thousand years ago it was a pine forest. When the glacier disappeared up north it reverted back to desert. Where I lived before 10,000 years ago it was covered either with ice or water, when the glacier disappeared water drained away and a rich soil was left behind other place the glacial drift was covered in a short time by a soil it richness was dependents on the amount rainfall that occurred after that. Desert can disappear and reappear in a wink of and eye in geological time scales us puny humans have little to do with it, foot prints or not.

From the linked report –

“All these people who watched this smokestack come down, they’re part of its history,” said Calvin Bigman, another local who came out to see the demolition. “They’re not only here to watch the action; they grew up being supported by their fathers and mothers who worked here. They know there’s a lot of history. I’m pretty sure they’re sad and they didn’t want to see this plant go down.”
Calvin’s late father, David Bigman, helped build the plant in the 70s and benefited from a good-paying union job in an otherwise economically depressed area. The younger Bigman worked off and on at the plant for 30 years as an electrician and welder.
“I was hired to tear it down,” Bigman said, “but I didn’t want to be a part of it because I didn’t want to see it go.”
He added that many of his friends had to sell their houses and move to Wyoming or Idaho to work in other coal-fired plants. “It’s going to change Page, which is also a tourist town,” Bigman said. “It’s going to have to rely on tourists now to keep the place alive.”

The video rang a bell. About 25 years ago when my now 34 year old sun was about 9, a cable channel had a show called “Dynamite Dynasty” We taped it, and he watched it over and over. it was about the Loizeaux family who are the founders and owners of Controlled Demolition Inc. I couldn’t finmd any links to that show, but there have been lots of articles about them:

“A Family Legacy, Built to Withstand Dynamite” By Steve Friess | Nov. 12, 2007 | https://www.nytimes.com/2007/11/12/us/12implode.html

“The Loizeauxes are the first family of a decidedly distinct business that started with Mr. Loizeaux’s late father, Jack Loizeaux, who as a Baltimore forestry worker realized in the late 1940s that dynamite was the easiest and fastest way to remove the roots of trees that had died from Dutch elm disease. That discovery led to a full-time job blowing up tree roots until others started asking him to knock down man-made structures, too. He went on to blast coal tipples, low bridges and eventually buildings.

“As business picked up, Jack Loizeaux founded Controlled Demolition Inc.; his wife was the first to use the term “implosion” as a softer way to describe using explosives to make a building crumble of its own weight. Jack Loizeaux’s two sons later took over his business, and now several of his grandchildren are on the job, too. The staff of Controlled Demolition, a multimillion-dollar business, includes about a dozen people, half of whom are family members who also share a 45-acre estate in Baltimore County.

“One of the reasons why this is a family business is anybody in this building is capable of taking all our lives with one mistake at any point in time,” said Mark Loizeaux, who lost much of his hearing and was badly banged up in 1973 when an unspent piece of dynamite exploded as he worked in a debris pile after an implosion. “There needs to be a high level of trust.”

* * *

The remarkable precision of the Loizeauxes’ work — the 32-story Stardust Hotel-Casino collapsed in less than 10 seconds in March — keeps them atop the field, said Alan Feldman, spokesman for MGM Mirage, which hired the Loizeauxes most recently to demolish the Boardwalk Hotel-Casino on the Strip.“They do what they do with the craftsmanship of a great shoemaker or carpenter, someone who does this fine, detailed work,” Mr. Feldman said. “It just so happens their fine detailed work is taking down big complex buildings.”

No my best guess is the new turbines are much bigger weigh much more, my younger brother would have all the details he spent most of his adult live overseeing these things going up. He has spent most of his adult life working for the construction companies that put them up his main job for many years was bidding the work and seeing the project of beginning to end. He has made good money doing it. May have put up the one that just cut down. He been all over the USA putting these monuments of stupidity up.

Nope.

Let’s break it down in general terms.

You have a huge concrete base, a big steel column, a rotating box with the generator and the blades.

So the assumption is we want to replace the generator and the blades with new models.

Where are these blades and generators? Up the top of the tower.

So two remove the old units you are going to need cranes. Big ones that – one assumes – cost big money to run.

Then you have to refurbish the existing mounts for the new generator, which is probably the easy bit, and then you need to life the new equipment back up to the top.

Then test and commission.

So, you get to keep the concrete and the post, but the blades and turbines are new, both to manufacture and install. Then there is the down time, the temp decommission and removing the old blades/turbine.

At a very rough guess I would say replacing these parts would be almost as expensive as a new install.
