Siemens Energy’s Green Dream Meets Reality: Renewables in Distress

From ZeroHedge

In a recent revelation, the green energy sector shows signs of distress, as illustrated by the plummeting shares of Siemens Energy. An article on ZeroHedge meticulously unfolds the tale of challenges and uncertainties clouding the renewable energy sector, with Siemens Energy at its epicenter.

“Siemens Energy shares in Germany crashed on Thursday after the company warned its wind turbine business is grappling with quality issues and offshore ramp-up challenges.”

https://www.zerohedge.com/commodities/siemens-energy-shares-crash-37-renewable-bust-sparks-green-panic

The company is in the throes of quality and operational challenges, which have significantly impacted its market performance, leading to a staggering 37% crash in its shares in Germany.

Siemens Energy candidly expressed its ongoing struggles, stating that it is

“working through the quality issues and is addressing the offshore ramp-up challenges as announced in the third quarter communication for fiscal year 2023.”

https://www.zerohedge.com/commodities/siemens-energy-shares-crash-37-renewable-bust-sparks-green-panic

The company also revealed a rather cautious approach moving forward, refraining from concluding new contracts for certain onshore platforms and exercising strict selectivity in the offshore business.

The article further unveils the broader landscape of challenges faced by the renewable energy sector. It’s not just Siemens Energy feeling the heat; the entire offshore wind power industry seems to be in the midst of a financial crisis.

“Soaring inflation costs have undercut the sector’s growth and left major projects dead in the water just when their output is most needed.”

https://www.zerohedge.com/commodities/siemens-energy-shares-crash-37-renewable-bust-sparks-green-panic

The narrative of Siemens Energy is not an isolated incident but seems to be a reflection of a broader trend in the renewable sector. Other giants in the industry, such as Orsted A/S, the world’s largest offshore wind farm developer, have also faced market adversities. Orsted A/S shares crashed due to warnings related to severe situations in US offshore wind projects, attributed to inflation, high interest rates, and supply chain woes.

In a rather grim portrayal of the sector’s health, the term ‘green panic’ has been coined, encapsulating the essence of the challenges faced by the renewable energy industry in the current macroeconomic environment. The article subtly underscores the gap between the ambitious green dreams and the harsh realities marked by financial and operational challenges.

In conclusion, the tale of Siemens Energy, as narrated by the article, serves as a mirror reflecting the turbulent waters navigated by the renewable energy sector. It brings to light the grim realities faced by the green energy companies as they collide with reality. The journey of Siemens Energy, marked by crashing shares and quality challenges, is emblematic of the broader struggles of the renewable industry in a world marked by economic uncertainties and operational challenges.

First Solar PV and now Turbines, the Chinese must be laughing their heads off as they lay waste to Western companies making Unicorn fart technology. They will instead supply these Turbines made using coal generated energy so Western Pols can virtue signal and become service only economies reliant on the CCP to supply manufactured goods.

Offshore Wind is an Economic and Environmental Catastrophe

EXCERPT

Authored by Edward Ring via American Greatness,

The S&P Global Clean Energy Index, comprised of major solar and wind power companies and other renewables-related businesses, is down some 32% in 2023, most of that in the last three months, i.e., in free-fall. The peak occurred before the start of the Ukraine events. The smart money sold and others sold as well.

The industry overpromised, submitted bids at prices, $/MWh, that were too low, while costs were increasing much greater than estimated, due to interest rates, inflation, energy/component/labor, a lack of specialized ships, plus supply chain constraints, plus greater than expected O&M/MWh, due to major design/engineering/quality control deficiencies, such as with Siemens onshore and offshore turbines.

As a result, the industry lost $billions each year, as reflected by the S&P index

When it comes to “renewables” wreaking havoc on the environment, wind turbines have some major helpers.

For example, over 500,000 square miles of biofuel plantations have already replaced farms and forests to replace a mere 4 percent of transportation fuel.

The US has about 350 million acres of cropland

About 35 million of about 95 million planted in corn is for producing ethanol, most of which is blended with gasoline to produce gasohol.

If the US were to replace all gasoline with pure ethanol, E100, about 450 million acres would need to in corn.

If the US were to replace all diesel with pure biodiesel, B100, about 670 million acres would need to be in soybeans.

https://www.windtaskforce.org/profiles/blogs/replacing-gasoline-and-diesel-fuel-with-biofuels

To source raw materials to build “sustainable” batteries, mining operations are scaling up, with no end in sight, in nations with appalling labor conditions and nonexistent environmental regulations. But the worst offender is the wind industry.

Governments printing money so they can pay bill always herald massive inflation.

Teams of accountants and budget specialists would be carrying presentations to their bosses highlighting inflation impacts to contracts, construction, buildings, transportation, air flights, employees, etc. etc.

That includes the impacts to ongoing projects.

These kinds of impacts are addressed every fiscal quarter, and discussed every accounting period (28 days).
Though the first warning signs regarding these companies was when they started moaning about their costs rising over a year ago.

Some numbers. Correctly calculated (unlike EIA) the LCOE of CCGT is about $58/MWh compared to onshore wind at about $146/MWh. The biased EIA says offshore wind is 3x onshore, so about 7.5x CCGT. (US natgas costs).

Reply to  PCman999
October 29, 2023 3:26 pm

The real LCOE of wind is a variable that depends on how much of its output must be curtailed at zero value or sold at negative prices. As wind penetration increases, those costs will push up the real cost of wind substantially – they act to reduce its capacity factor. Of course, LCOE take no account of all the other costs imposed by rising levels of wind capacity, including extra grid capacity, extra grid stabilisation equipment and the cost of maintaining backup for when the wind doesn’t blow. These costs rise very rapidly once renewables provide in the region of 60% of energy, but are already appreciable at that level. LCOE is a very misleading statistic.

Since Western governments globally have committed to Green power goals, and since these governments seem to be firmly in power given the lack of intelligence of the voting public, or by corruption of the voting process, whatever, I do not doubt that the necessary governmental interventions will occur, at least in the short term. Long term, as these same governments go bankrupt, well… I cannot see that far into the future.
So, for investors, what to do? Go long or go short companies with exposure to offshore wind? That is the question we should be asking ourselves.

I am very interested in whether the issue at Siemens — bearing and gear failures — is endmeic among all wind turbine manufacturers. Please don’t respond with the usual empty polemics that dominate so many comment sections, but knowledgable engineering information, with links.

Do Vesta and GE have the same mechanical problem related to chaotic behavior of wind fields and their impact on bearings that has killed Siemens’s turbines, or have other manfacturers figured out how to use different materials or designs, making this issue unique to Siemens? Again, please provide evidence, not just yammering. Thanks in advance.

I work for a G&T. We buy Siemens voltage regulators. We had so many fail shortly after installation that it be came policy to de-tank them and rebuild them when they arrived at our service center. Regulator failure is quite “exciting.” You don’t want to be inside the station fence when one fails.

Reply to  0perator
October 29, 2023 11:27 am

I am jumping down the rabbit hole on this issue, and am willing to slog through engineering papers, one of which I have found and read. My major question, to repeat, is whether the bearing issue (which has been a big problem ever since wind turbine production and installation began ramping up a decade ago) is universal or limited to Siemens.

My guess is that its universal, but that’s only my guess, and I seek objective and detailed information that’s understandable to an intelligent, reasonably diligent non-specialist. Siemens Gamesa makes all of the wind turbines installed not far from where I live, and I believe the large majority of turbines installed throughout the United States.

My guess is that the bearings issue, which I believe to be quite serious, has been obscured from general view because installations have outpaced failures, so for the time being the share of electricity generated by wind has risen to 10%. I am a retired financial analyst, and it reminds me of retailing corporations, and the difference between total revenue growth and sale-store revenue growth.

Retail analysts have long learned to look at the total AND at same-store numbers to ascertain the health of these enterprises. Same goes for companies selling products through retailers; there, you look at total sales but also at “sell through” (ongoing sales) and the number of retail “doors” where the products are sold.

This is a long comment, and I hope you have been patient. I am wondering whether the mechanical issue with bearings and chaotic wind fields is a Siemens problem or endemic to all wind turbines, and wanted to illustrate how I — a non-specialist — am thinking about it in terms I can readily understand.

Again, I’m sufficiently interested to be willing to dive into fairly specialized discussions, but they need to be well-documented, hence my original disdain for mere “yammering.”

Reply to  JakeJ
October 29, 2023 12:52 pm

Right. It’s a universal problem with every single manufacturer, bar none. Most wind turbines have been scaled up from smaller designs which are pushing the bearings, in particular, way beyond their design loads. Siemens have been working on this problem for some years after it became obvious in an offshore array that had multiple in-warranty failures. Google this and you will find a long stream of articles discussing bearing failure in general terms, but not one piece of data from any manufacturers to show many of the details or scale of the problem. No manufacturer will want to encourage a loss of confidence in their product, especially when they are trying to work on a solution to the problem. It’s also obvious that none of the manufacturers has been able to solve the problem, despite years of effort, or the news would be everywhere, including a rush from their competitors to buy the money-saving component!

Reply to  Richard Page
October 29, 2023 2:43 pm

As I understood it the problem is universal and already solved.

If the bearings lie still, they warp under the weight. Then when they turn again they heat up, lose efficiency and sometimes, burn out.

Solution: Turn the blades every so often regardless of the weather. Just pull electricity from the grid and keep the bearings turned.

My ignorant guesswork is that Siemens offshore windfarms cannot do this because… the windfarms are not yet connected to the grid.

There are still lots of discussion over who is going to pay for the extra connections for these new windfarms.

I did more than one search and found a technical paper that pretty strongly implies that this is a universal issue.

The problems apply to the larger turbines that have been coming to the market in more recent years. You may find these articles a useful background (and there are also some well informed comments):

https://watt-logic.com/2023/06/14/wind-farm-costs/

https://watt-logic.com/2023/10/10/off-shore-wind-targets-at-risk/

If you really want to start getting your head around the engineering issues, I would recommend getting a good basic understanding from working through this tutorial:

http://drømstørre.dk/wp-content/wind/miller/windpower%20web/en/tour/wres/index.htm

It introduces many of the engineering issues in an easily understood way, and ties them in with economics and gives a good background on the wind itself.

Large turbine diameters mean there can be a big difference in wind speed at the top and bottom of the travel of each blade, with the lower point when passing the tower made worse by the shadowing effect of the tower itself preventing the air from exiting the turbine as efficiently. The result is rotating stresses on the turbine, and varying bending stresses on the blades that are therefore constantly being flexed. These problems are actually much worse for tidal stream turbines because water is much denser than air: attempts to increase tidal turbine diameters to try to harvest more energy were largely abandoned because they were rapidly wrecked by the stresses. However, because tidal stream is still rather more experimental than commercial, it tends to be easier to access papers on them. This one gives some interesting insights on where stresses occur, and introduces some finite element analysis and CFD (Computational Fluid Dynamics!)

It’s an intrinsic design fault in all wind turbines = they have a shaft that is not supported at both its ends

A perfect example is the coolant pump (water) pump on VW diesel engines, driven off the cambelt as it is.
The cam belt is carrying a lot of load but the thing driving it (crankshaft) has a bearing at each end and one between each cylinder.
The thing being driven (camshaft) is supported at both its ends and at its centre.
The water pump is supported by only one bearing which also has to double up as the water seal
VW water pumps fail like clockwork between 80 and 90,000 miles if you go past the specified cambelt service/replacement at 75,000 miles – it is a well known weakness.
New cambelts always come in kits with a new water pump.

The bearing on a windmill is in the exact same situation – they need a support-bearing in front of the blades as well as behind.
As they are, all windmills are designed to destroy themselves and it is not a matter of quality control or materials used to make the bearings.

It’s probably also that because the blades aren’t properly supported (the single bearing allows them to move/flex too much) is why (onshore) windmills are retired at 15 years due to cracking/flaking/peeling of the fibreglass that the’re made of.
The single bearing allows them to flex too much and they crumble

Offshore mills will have an even harder life and will be lucky to get past 12 years

You don’t need links to support that, it is just Simple Basic Engineering Mechanics that even teenage boys learn from riding pushbikes

One of the few places wind energy makes *some* sense

  • A long narrow country with existing grid to match
  • Situated in the latitudes where wind is almost constant
  • Existing distributed hydro generation which provides the frequency stability that wind doesnt
  • Wind isnt subsidised ahead of hydro and the better bet steam geothermal- which has taken off in last 20 years

Already at 80-90% renewable so no need to ‘throw good sense to the wind’ to worship the carbon god

The fact that offshore wind electricity costs are 5-10 times that of CCGT is proof that it takes more energy to produce, install, and operate these systems than they can ever generate. The whole reason they are to be built is to save CO2 emissions vs. fossil fuels. If they consume more energy than they can produce, then their whole reason to exist is a falsehood.

Here’s the summary from your linked article. I’ve highlighted in bold the particularly relevant points that I tend to agree with.

“Thus society seems to be caught in a dilemma unlike anything experienced in the last few centuries. During that time most problems (such as needs for more agricultural output, worker pay, transport, pensions, schools and social services) were solved by throwing more technology investments and energy at the problem. In many senses this approach worked, for many of these problems were resolved or at least ameliorated, although at each step populations grew so that more potential issues had to be served. 

In a general sense all of this was possible only because there was an abundance of cheap (i.e. high EROI) high quality energy, mostly oil, gas or electricity. We believe that the future is likely to be very different, for while there remains considerable energy in the ground it is unlikely to be exploitable cheaply, or eventually at all, because of its decreasing EROI.

Alternatives such as photovoltaics and wind turbines are unlikely to be nearly as cheap energetically or economically as past oil and gas when backup costs are considered. 
In addition there are increasing costs everywhere pertaining to potential climate changes and other pollutants. Any transition to solar energies would require massive investments of fossil fuels. Despite many claims to the contrary—from oil and gas advocates on the one hand and solar advocates on the other—we see no easy solution to these issues when EROI is considered. 

If any resolution to these problems is possible it is probable that it would have to come at least as much from an adjustment of society’s aspirations for increased material affluence and an increase in willingness to share as from technology. 

Unfortunately recent political events do not leave us with great optimism that such changes in societal values will be forthcoming.”

In other words, with reference to the final sentence in the quote, we are stuck in our ways of satisfying our greed, ego and vanity. (Well, most of us are. A few of us have the intelligence, pragmatism and self-control, to understand what is necessary and what isn’t.) (wink)

I’m not somehow an advocate of wind turbines; other way around, in fact. If nothing else, I consider them a plague on the landscapes of my beloved wide open West. That said, however, they appear to have a high EROEI. The 18 number is repeated in other articles. My question would revolve (pardon the pun) around the energy expenditure in replacing their endemically defective hubs.

Oh, and it’s not “my” link. It’s something I found.

I just very quickly skimmed this article. In fact, it is an analysis of EROI. The discussion of wind and solar EROI was especially vague – throwing out some high values but with caveats that maybe, maybe, things aren’t so rosy as the references state. I did not see where it discusses wind or solar in the context of John’s comment. There is no mention of any system that “uses its own power output to replicate itself”.

I’ve pondered for some time – just how much of a headstart would be necessary to create a self-sustaining industrial complex that can regenerate itself using just solar and wind for it’s energy, and just materials made without the use of FF. Clearly, such a complex could not bootstrap itself into existent. So, the headstart would be a full blown FF produced complex of buildings, streets, wells, foundries, and so. With, say, a hundred square miles of arrays and wind turbines. Could it make it? My gut says no. In twenty years it will be an abandoned ghost town. Even getting supplies with FF content wouldn’t make much of a difference.

I think there are major downsides to wind and solar, but the fact is that they both have positive EROEI. I posted one link, but anyone who does a search will see that the EROEI is positive for both of them. Opinions not based on facts are worthless.

I see no examples of solar PV or wind power systems being used to produce more of these systems in your link. Try again.

Green panic? When was there not a “green panic”?

Their problem is that they have already abused so many of the adjectives, adverbs and superlatives in the English language that people are becoming inured to it all.

The day may come when they find the cupboard bare.
