Siemens Gamesa Renewable Energy has big problems, and it’s going to cost the company billions – what’s wrong with its onshore wind turbines?
Siemens Gamesa Renewable Energy SA is Siemens Energy AG’s wind turbine unit, and it’s one of the world’s largest wind turbine makers. Its turbine problems are expected to result in up to $5 billion in net loss for the parent company.
The company’s Spanish division found that its onshore wind turbines had worse-than-expected quality flaws. The company will have to fix flaws in rotor blades and bearings, ranging from component failures to small cracks.
We now know that Siemens Gamesa Renewable Energy’s onshore wind turbine issues have to do with wrinkles in rotor blades and particles in the bearings section on the 4.X and 5.X, the turbine maker’s two most recent onshore wind turbine platforms. Bloombergreports that “the problems center on the discovery that a main piece on the frame of a wind turbine can move or twist over time, potentially damaging other critical components.”
About 2,100 4.X and 800 5.X models are in use. Siemens Gamesa says that 15-30% of them are problematic. The turbines can still be operated, but the company’s plan is to implement a quality management system and fix the problems within regular service intervals.
Siemens Gamesa Renewable Energy’s CEO, Jocken Eickholt, said in a call on Monday that the company “sold wind turbines that were not sufficiently tested.” Eickholt also said that the quality issues are unlikely to happen again at the same scale.
It’s going to cost the company €1.6 billion to fix these issues, and most of the costs will occur in 2024 and 2025. Siemens Energy has set up a special committee to address the quality and productivity problems, and Eickholt says that going forward, the company would place “stability and profitability before growth.”
Bloombergreports that the company will present the result of a strategic review in November.

The German city of Karlsruhe is setting an example for sustainability in waste management by deploying a fleet of 18 Mercedes-Benz eEconic electric garbage trucks that are helping make the streets cleaner, quieter, and a lot less stinky.
Since the end of September, the city of Karlsruhe has been relying on Mercedes’ fully electric waste collection vehicles throughout, with none of the area-specific restrictions or limited rollout strategies for one or two trucks at a time that typically accompany stories like these. Instead, the city is using the Mercedes eEconics for the same stuff they’d use the diesel versions for: residual waste disposal, paper collection, and bulky waste collection.
Normal garbage duty, in other words. And, in such daily use, they do a great job. The trucks cover an average route distance of around 80 km (about 50 miles) on 112 kWh battery packs (usable capacity is ~97 kWh) which can be reliably completed in single-shift operation without intermediate charging — thanks, in part, to Mercedes’ efficient electric motors and regenerative braking that shines in the trucks’ typical stop-and-go duty cycles.
More than a single shift, in fact. The fleet managers report that after “a good 80 kilometers with around 60 stops on its daily route,” energy consumption was only around 35% of the battery capacity, meaning the charge level dropped from 100% to 65% and 64% respectively.

At the same time, CO₂ emissions are significantly reduced: depending on the area of application, each eEconic can save between 150 and 170 tons of CO₂ per year. This results in a total potential annual saving of around 1,200 tons of CO₂ emissions.
The purchase of the electric vehicles was funded by the Federal Ministry of Transport (BMV) as part of the guideline on the promotion of light and heavy commercial vehicles with alternative, climate-friendly drives and the associated refueling and charging infrastructure (KsNI). The funding guideline was coordinated by NOW GmbH, and applications were approved by the Federal Office for Logistics and Mobility.
Electrek’s Take
Look, you know me. There is absolutely ZERO chance that I’ll be able to remain objective about anything that’s putting down more than four thousand lb-ft of torque. Make that thing quieter, cleaner, and generally better for me and my community, and there’s even less of a chance of me saying anything critical about it.

Electreon just took a big step toward expanding wireless EV charging. The Israel-based company signed a memorandum of understanding (MoU) to acquire the assets of InductEV, a Pennsylvania-based firm known for its ultra-fast, high-power static wireless charging systems used by heavy-duty electric transit and freight fleets.
If the deal closes after due diligence and regulatory approvals, the combined company would bring together Electreon’s dynamic wireless charging tech – the kind that can charge vehicles while they drive – with InductEV’s high-power stationary systems. That would create one of the most complete wireless charging portfolios on the market, covering everything from passenger EVs to vans, buses, heavy-duty trucks, and even autonomous vehicles.
Electreon and InductEV together hold around 400 granted and pending patents, and have a lot of field experience across their respective projects. Electreon says that pairing its manufacturing capabilities and global footprint with InductEV’s ultra-fast tech will help streamline and speed up fleet electrification.
Both companies already work with major vehicle OEMs, which Electreon asserts will make integrating wireless charging into future vehicle platforms easier.

Electreon CEO Oren Ezer said the deal would combine the two companies into “a truly global powerhouse for wireless EV charging.” He added that “the decision by InductEV’s shareholders to invest in Electreon is a tremendous vote of confidence in our shared vision.”
InductEV CEO John F. Rizzo said, “Together, we’re combining world-class innovation with real-world experience to deliver even greater value to our North American and European customers and accelerate the shift to wireless power for sustainable commercial transportation.”

The Dolphin Surf is already one of Europe’s cheapest EVs, yet BYD may have an even more affordable electric car up its sleeve.
Is BYD launching the Racco mini EV in Europe?
BYD revealed the Racco at last month’s Japan Auto Show, its first EV designed exclusively for overseas markets.
The mini EV, or “kei car,” is launching in Japan, where over 1.55 million of them were sold last year, accounting for about a third of new vehicles sold.
Although Japan has been a brutal market for foreign brands to crack, BYD believes it may have an edge. The Racco measures 3,395 mm in length, 1,475 mm in width, and 1,800 mm in height, or about 600 mm longer than the Dolphin Surf.

That’s about the size of the Nissan Sakura EV, Japan’s best-selling electric car. Like the Sakura and most kei cars, the Racco has a boxy, upright stance. It has four doors, with the back two sliding open.

Powered by a 20 kWh battery pack, the mini EV is expected to have a driving range of around 180 km (112 miles).
BYD is using its Blade lithium iron phosphate (LFP) battery packs to keep costs down. Although prices have yet to be revealed, the Racco is expected to start at around 2.5 million yen ($18,000) in Japan, putting it on par with the Nissan Sakura.

If it launched in Europe, the Racco could go on sale for under £15,000 ($20,000), putting it on par with the Dacia Spring (£14,995) and Leapmotor T03 (£15,995). The BYD Dolphin Surf currently starts at £18,650 ($24,300).
Although it will arrive in Japan first, BYD may launch its smallest, cheapest EV in Europe after all. BYD’s vice president Stella Li suggested to Autocar that the Racco could play a key role globally as an affordable, entry-level EV.

“In Japan, we are already launching a kei car; we will be very interested to follow the EU regulation,” Li said, adding, “If there’s some space, we can bring that car here.”
The regulation Li is referring to is the new “E-car” segment that the European Commission president, Ursula Von der Leyen, called for in September.
Von der Leyen said that Europe “should have its own E-car,” where “E” stands for efficient, economical, and European, and added “we cannot let China and others conquer this market.”
The Racco could sit underneath the Dolphin Surf in BYD’s growing European lineup. However, the company is focusing on expanding hybrid options. Li said launching Racco was “not a topic” the company is immediately focused on.
The Seal U, Europe’s best-selling plug-in hybrid through September, will be the first vehicle built at BYD’s new factory in Turkey, as it seeks to gain an edge through local production.
