As the biggest players in wind energy gear up to report quarterly earnings, supply-chain reliability issues are front and center for both stock analysts and industry leaders.
Siemens Energy made the headlines earlier this year when it scrapped its profit forecast and warned that costly failures at wind turbine subsidiary Siemens Gamesa could drag on for years.
It sparked concerns about wider problems across the industry and thrust Europe’s wind energy giants’ earnings into the spotlight.
Siemens Energy is set to report its fiscal fourth-quarter results on Nov. 15. Its shares are currently down more than 35% year-to-date.
Aside from the turbine problems, the German energy giant posted orders of around 14.9 billion euros ($15.7 billion) for its third quarter, a more-than 50% increase from the previous year, primarily driven by large orders at Siemens Gamesa and Grid Technologies. Yet the 2.2 billion euro charge due to Gamesa’s quality issues prompted Siemens Energy to forecast a net loss for the fiscal year of 4.5 billion euros.
Ahead of its fourth-quarter earnings, analysts at Kepler Cheuvreux suggested in a research note Tuesday that despite having already warned on profits, the company “remains vulnerable to large negative cashflow swings in the next fiscal year.”
“We expect Siemens Gamesa to suffer very weak order intake in H1, which will combine with extensive delivery delays and rising customer penalty payments. Challenges at Siemens Gamesa will continue to overshadow resilience in the group’s other divisions,” they added.
Morgan Stanley cut its price target for Siemens Energy from 20 euros per share to 18 euros per share, but retains an overweight long-term strategic position on the company’s stock.
“Valuation for Siemens Energy is currently factoring in a negative value for the Gamesa division, which we believe may have been over penalized,” Morgan Stanley capital goods analyst Ben Uglow said in a research note Monday.
“While we acknowledge the low visibility on Gamesa margin trajectory and that rebuilding investor confidence will take time, we remain Overweight on undemanding valuation and good fundamentals of the Gas & Grid businesses.”
Elsewhere, Deutsche Bank earlier this week slashed its 12-month share price forecast for Danish wind energy producer Ørsted by 36% ahead of its interim earnings report on Nov. 1. The stock has already halved in value so far this year.

Deutsche had previously highlighted challenges in the wind turbine industry including supplier delays, lower tax credits and rising rates. However, Ørsted’s share price tanked further earlier this year when it raised the possibility of a 2.1-billion-euro impairment charge in its U.S. offshore wind portfolio.
Meanwhile, Danish wind turbine manufacturer Vestas — despite continuing to bag significant orders — has seen its shares plunge by around 30% year-to-date as reliability concerns plague the wider industry. Vestas publishes its interim financial report for the third quarter on Nov. 8.
Supply chain worries
ONYX Insight, which monitors wind turbines and tracks over 14,000 across 30 countries, revealed in a report Tuesday that supply chains remain the greatest challenge to the sector, with reliability not far behind.
The analytics firm, which is owned by British energy giant BP, interviewed senior personnel at over 40 owners and operators of wind turbines around the world in order to gauge the mood of industry leaders, and found that 57% cited the supply chain as the main obstacle to their operations.
ONYX Chief Commercial Officer Ashley Crowther said the lingering impacts of Covid-19 on manufacturing had just begun to heal — and then Russia’s invasion of Ukraine and the subsequent surge in inflation hit.
“Survey participants are now citing delays on new projects due to longer lead times for supply of new turbines and significant price increases,” Crowther said in the report.
“This is in line with what OEMs have told their investors, for example Vestas noting in their 2022 annual report they ‘increased our average selling prices of our wind energy solutions by 29%’. Similarly for major components, particularly main bearings on newer turbines with large rotor diameters, long delays are leaving turbines offline for extended periods.”
Although supply chain issues are creating problems for operators, the most direct impact has been on OEMs like Siemens Gamesa and Vestas, Crowther noted, as has been evident in recent financial results.
“Major western OEMs have recently reported losses or profit warnings and announced major restructuring projects in order to address the challenges they are facing. Some are even re-thinking their approach to the aftermarket which was always seen as the most profitable part of the business,” he added.
Reliability issues
Those surveyed by ONYX also expressed reliability concerns, with 69% expecting more reliability issues due to aging assets and 56% seeing problems associated with new turbine technology. Just 22% expected fewer reliability issues due to new turbine technology improvements.
“As the sector matures, turbines are getting older and the failure rate of electromechanical systems are increasing with age,” Crowther noted.
“Likewise, the initial operating period of newer turbines are seeing a rash of failures due to shorter development cycles, new turbine designs, and a squeeze on turbine prices. This is resulting in machines that are not durable enough.”
During an initial boom in the wind industry a number of years ago, OEMs faced huge market demand and, in turn, created a variety of turbine designs delivered on short cycles to a customer base seeking to generate more energy with greater efficiency at lower cost, Crowther explained.
“Fast-forward to the present and between the perfect storm of supply chain issues and too many turbine designs to support, OEMs have been losing significant amounts of money, including those paid out in liquidated damages (LDs),” he said.
“Manufacturers have been locked into a price competition spiral, attempting to produce larger turbines for more competitive pricing. But with bigger turbines produced in shorter production cycles, it’s no surprise that manufacturing quality has diminished.”
Thanks to Trump’s repeated executive order attacks on US clean energy policy, nearly $8 billion in investments and 16 new large-scale factories and other projects were cancelled, closed, or downsized in Q1 2025.
The $7.9 billion in investments withdrawn since January are more than three times the total investments cancelled over the previous 30 months, according to nonpartisan policy group E2’s latest Clean Economy Works monthly update.
However, companies continue to invest in the US renewable sector. Businesses in March announced 10 projects worth more than $1.6 billion for new solar, EV, and grid and transmission equipment factories across six states. That includes Tesla’s plan to invest $200 million in a battery factory near Houston that’s expected to create at least 1,500 new jobs. Combined, the projects are expected to create at least 5,000 new permanent jobs if completed.
Michael Timberlake of E2 said, “Clean energy companies still want to invest in America, but uncertainty over Trump administration policies and the future of critical clean energy tax credits are taking a clear toll. If this self-inflicted and unnecessary market uncertainty continues, we’ll almost certainly see more projects paused, more construction halted, and more job opportunities disappear.”
March’s 10 new projects bring the overall number of major clean energy projects tracked by E2 to 390 across 42 states and Puerto Rico. Companies have said they plan to invest more than $133 billion in these projects and hire 122,000 permanent workers.
Since Congress passed federal clean energy tax credits in August 2022, 34 clean energy projects have been cancelled, downsized, or shut down altogether, wiping out more than 15,000 jobs and scrapping $10 billion in planned investment, according to E2 and Atlas Public Policy.
However, in just the first three months of 2025, after Trump started rolling back clean energy policies, 13 projects were scrapped or scaled back, totaling more than $5 billion. That includes Bosch pulling the plug on its $200 million hydrogen fuel cell plant in South Carolina and Freyr Battery canceling its $2.5 billion battery factory in Georgia.
Republican-led districts have reaped the biggest rewards from Biden’s clean energy tax credits, but they’re also taking the biggest hits under Trump. So far, more than $6 billion in projects and over 10,000 jobs have been wiped out in GOP districts alone.
And the stakes are high. Through March, Republican districts have claimed 62% of all clean energy project announcements, 71% of the jobs, and a staggering 83% of the total investment.
A full map and list of announcements can be seen on E2’s website here. E2 says it will incorporate cancellation data in the coming weeks.

Tesla has reportedly delayed the launch of its new “affordable EV,” which is believed to be a stripped-down Model Y, in the United States.
Last year, Tesla CEO Elon Musk made a pivotal decision that altered the automaker’s direction for the next few years.
The CEO canceled Tesla’s plan to build a cheaper new “$25,000 vehicle” on its next-generation “unboxed” vehicle platform to focus solely on the Robotaxi, utilizing the latest technology, and instead, Tesla plans to build more affordable EVs, though more expensive than previously announced, on its existing Model Y platform.
Musk has believed that Tesla is on the verge of solving self-driving technology for the last few years, and because of that, he believes that a $25,000 EV wouldn’t make sense, as self-driving ride-hailing fleets would take over the lower end of the car market.
However, he has been consistently wrong about Tesla solving self-driving, which he first said would happen in 2019.
In the meantime, Tesla’s sales have been decreasing and the automaker had to throttle down production at all its manufacturing facilities.
That’s why, instead of building new, more affordable EVs on new production lines, Musk decided to greenlight new vehicles built on the same production lines as Model 3 and Model Y – increasing the utilization rate of its existing manufacturing lines.
Those vehicles have been described as “stripped-down Model Ys” with fewer features and cheaper materials, which Tesla said would launch in “the first half of 2025.”
Reuters is now reporting that Tesla is seeing a delay of “at least months” in launching the first new “lower-cost Model Y” in the US:
Tesla has promised affordable vehicles beginning in the first half of the year, offering a potential boost to flagging sales. Global production of the lower-cost Model Y, internally codenamed E41, is expected to begin in the United States, the sources said, but it would be at least months later than Tesla’s public plan, they added, offering a range of revised targets from the third quarter to early next year.
Along with the delay, the report also claims that Tesla aims to produce 250,000 units of the new model in the US by 2026. This would match Tesla’s currently reduced production capacity at Gigafactory Texas and Fremont factory.
The report follows other recent reports coming from China that also claimed Tesla’s new “affordable EVs” are “stripped-down Model Ys.”
The Chinese report references the new version of the Model 3 that Tesla launched in Mexico last year. It’s a regular Model 3, but Tesla removed some features, like the second-row screen, ambient lighting strip, and it uses fabric interior material rather than Tesla’s usual vegan leather.
The new Reuters report also said that Tesla planned to follow the stripped-down Model Y with a similar Model 3.
In China, the new vehicle was expected to come in the second half of 2025, and Tesla was waiting to see the impact of the updated Model Y, which launched earlier this year.
Electrek’s Take
These reports lend weight to what we have been saying for a year now: Tesla’s “more affordable EVs” will essentially be stripped-down versions of the Model Y and Model 3.
While they will enable Tesla to utilize its currently underutilized factories more efficiently, they will also cannibalize its existing Model 3 and Y lineup and significantly reduce its already dwindling gross margins.
I think Musk will sell the move as being good in the long term because it will allow Tesla to deploy more vehicles, which will later generate more revenue through the purchase of the “Full Self-Driving” (FSD) package.
However, that has been his argument for years, and it has yet to pan out as FSD still requires driver supervision and likely will for years to come, resulting in an extremely low take-rate for the $8,000 package.
