A project to build a facility described as “the world’s largest offshore wind farm” took a big step forward this month by producing its first power.

Located in the North Sea, over 130 kilometers off England’s northeast coast, the Dogger Bank Wind Farm still has some way to go before it’s fully operational, but the installation and powering up of its first turbine is a major feat in itself.

That’s because GE Vernova’s Haliade-X turbines stand 260 meters tall — that’s higher than San Francisco’s Golden Gate Bridge — and have blades measuring 107 meters.

Turbine installation at Dogger Bank has required a huge amount of planning and preparation, with the Voltaire — a specialist vessel designed and built by the family-owned Jan De Nul Group — playing a key role.

With a lifting capacity of 3,200 metric tons, the Voltaire — named after the 18th-century French philosopher — will have installed a total of 277 Haliade-X turbines when its work is complete.

Described by Dogger Bank as the “largest offshore jack-up installation vessel ever built,” in many ways, it’s the pinnacle of an extensive supply chain involving numerous businesses and stakeholders.

The logistics are complex and multi-layered, with water depth a particular issue.

The sea in the Dogger Bank Offshore Development Zone is up to 63 meters deep, meaning the Voltaire’s ability to work in deeper waters is crucial. 

This is where its four legs come into play.

According to Jan De Nul, the legs of the Voltaire — which was built at the COSCO Shipping Shipyard in China — enable it to lift itself above the water’s surface.

With each leg measuring roughly 130 meters in length, they highlight the scale of equipment required to install huge offshore wind turbines like GE’s Haliade-X.

In an online Q&A before installations at Dogger Bank began, Jan De Nul’s Rutger Standaert spoke of their importance. “Thanks to those legs, the Voltaire can effectively operate at a water depth of 80 meters,” Standaert, who is manager of vessel construction at the business, said.

He noted that the Voltaire’s capabilities would enable installations further out to sea, allowing it to play a key role in the emerging floating offshore wind sector.

“Off the Scottish coast, for example, expensive floating windfarms are often the only way to tap into offshore wind,” he said. “The water is too deep for fixed windfarms, but the Voltaire can offer new opportunities.”

Thinking big

Once completed, the Dogger Bank Wind Farm will have a total capacity of 3.6 gigawatts (GW) and be able to power as many as six million homes per year, according to its developers.

Work on the project is taking place over three phases: Dogger Bank A, B, and C. A fourth phase of the wind farm known as Dogger Bank D has also been proposed, and would increase its capacity even further.

Søren Lassen is head of offshore wind research at Wood Mackenzie, a research and consultancy group. He described Dogger Bank as “a huge project, especially if you combine the three phases.”

“It is a project that requires a lot of preparation,” he told CNBC. “There’s the logistics in terms of having the vessels to do the installation … and then of course, you also have the logistics in terms of getting the components to the marshaling port.”

Both of these aspects were being made “a lot more complicated” by the use of next-generation turbines and a next-generation installation vessel, Lassen said.

“You have … a lot of innovation that goes into this. And not only do you need a new vessel or new components, you also need new factories to build those components.”

As such, a slew of upgrades and adjustments were needed to “reverberate throughout the entire value chain” for operations to run smoothly, he added.

Bigger turbines, bigger challenges?

Thanks to their sheer size, larger turbine designs have created a specific set of needs for the offshore wind sector and sites like the Dogger Bank Wind Farm.

“From cranes to vessels, we use a number of specially designed pieces of equipment to transport the Haliade-X turbines that will be used in this project,” a spokesperson for GE Offshore Wind said in a statement sent to CNBC.

Wood Mackenzie’s Lassen stressed the importance of having dedicated transportation vessels, noting that the towers of turbines need to be broken into three or four sections in order to fit on board.  

Massive blades represent the biggest challenge, he said, as they have to be laid flat. “And that just means that you need a very, very long transportation vessel, [and] that you need to stack them up accordingly.”

Meanwhile, delays or bottlenecks can have far-reaching — and expensive — consequences.

Lassen cited the example of blades not being delivered on time, which leads to vessels having to “go away and then come back half a year later to do the installation. This is very costly, of course.”

And delays also lead to lost revenue.

“These projects are going out [and] generating a lot of power from the day that they’re being installed, pretty much,” Lassen added.

“So any delays [and] you’re also losing a lot of revenue, especially right now when the power prices are really, really high.”

The bigger picture

Offshore wind farms are set to play a significant role in reducing emissions and hitting net zero goals in the years ahead — but a supply chain that’s well-run and reliable will be key to the industry’s success.

This is set to cost serious money. According to Wood Mackenzie, a base case of 30 GW of installations per year by 2030 — excluding China — will require investment of around $27 billion by 2026 to build out supply chains.

“The supply chain needs to invest,” Lassen said, adding that it also needed capital, certainty and concrete, firm orders. However, cost pressures mean there is currently uncertainty over projects planned for 2025, 2026 and 2027.

“Any delays to these projects takes away volume from the supply chain, and the supply chain needs that volume to convert it into revenue to build new factories,” Lassen explained.

It is crucial that projects planned for the next few years go ahead, he added. “That helps the underlying supply chain ramp up so they can build the capacity [for] ’27, ’28, ’29 and well into the 2030s as well.”

Greenlane launches a second long-haul EV truck corridor pilot

Greenlane launches a second long-haul EV truck corridor pilot

Greenlane is firing up its second commercial EV truck charging corridor – this time connecting Southern California to Phoenix along Interstate 10. The move targets a major gap in electric freight infrastructure on one of the busiest shipping routes in the US.

Greenlane’s new electric truck corridor is backed by a strategic partnership with electric truck maker Windrose Technology, which has already proved the route’s viability. Its R700 Class 8 electric semi pulled off single-charge trips from Greenlane’s flagship Colton, California, site to Phoenix – nearly 300 miles – with a gross combined weight of 74,420 pounds and still had 12% battery left.

That’s no small feat for long-haul freight. Windrose also completed a Colton-to-Las Vegas run on I-15 under similar conditions. The trucks can charge fast, too – the R700 hit a peak 772 kW using dual-gun charging at Colton, cutting downtime for heavy-duty operations.

Windrose plans to build 2,000 electric trucks in 2026 and ramp up to 10,000 in 2027 worldwide. “Electric long-haul trucking isn’t just theory – it’s proven real-world performance,” said Windrose founder and CEO Wen Han.

The I-10 corridor will link Greenlane’s Colton hub to new sites in Blythe, California, and Greater Phoenix, Arizona. It’s part of the company’s larger plan to create a nationwide public charging network for medium- and heavy-duty fleets.

Electric trucking carrier Nevoya will be among the first customers to run the corridor. The company will use the Colton site as a charging and driver support base while operating battery-electric trucks along both I-10 and I-15.

Greenlane’s Colton flagship opened in April and packs over 40 high-speed chargers, including 12 pull-through bays for semis and 29 bobtail lanes. The site also has restrooms, Wi-Fi, 24/7 security, carports, office space, and parking – the kind of amenities long-haul drivers need on the road.

Rivian is working on a steer-by-wire system – and rear wheel steering (updated)

Rivian is working on a steer-by-wire system - and rear wheel steering (updated)

Rivian has posted a job listing for a steering engineer, specifically mentioning work on a future steer-by-wire system for the company.

Update, Aug 11: Rivian has now specifically mentioned rear-wheel steering in a job posting.

Steer-by-wire is an automotive concept that has been around for a long time, but hasn’t yet reached mass adoption. The idea is to replace (or supplement) mechanical linkages between the steering wheel and the wheels with electronic actuators instead.

There are a number of potential benefits to this, like allowing more customizability or adaptability to a steering system, reducing mechanical complexity, or adding speed-sensitive variable steering ratios.

Although there are also disadvantages, like a reduction in steering feel (although, since most cars are moving to electronic power steering, that was already gone anyway).

But few cars have implemented steer-by-wire systems, or at least not fully committed to them, given that mechanical steering racks are a relatively solved problem and the general inertia of the car industry which would rather stick with a solution they know than switch to something better (haven’t we here, at this EV publication, heard *that* one before…). There’s also the matter of regulations, which have often been written to require mechanical steering systems, and may need updating to allow for steer by wire.

But, steer by wire made it into mass production with the release of the Tesla Cybertruck. This was big news when Tesla committed to this – at the time, it was the only thing on the road to exclusively use a steer by wire system, though there are other cars with partial steer by wire (for example, mechanical front wheel steering, and steer by wire rear-wheel steering).

But it seems to have opened the floodgates, as a number of other companies are working on or have since released steer by wire systems (Lexus, for example).

And now, it looks like Rivian is one of those companies – though we don’t know if it’s for the front or rear. (Update: Well, now we know, it looks like they are at the very least developing a rear-wheel steering system, according to another job listing. Though the company might still be working on steer-by-wire for the whole vehicle, too)

The company posted a job listing for “Sr. Staff Technical Program Manager, Steering Actuator System,” based at its Irvine, CA headquarters (spotted by Rivianforums). This wouldn’t be so exceptional, except that the job posting also specifically points out that “you’ll have full cradle-to-grave ownership of the SBW subsystem.”

So – we know they’re working on steer by wire, to some extent.

But a few other EVs, particularly large EVs like the Rivian R1 platform is, use steer by wire just for the rear wheels – for example the Hummer EV and Rolls-Royce Spectre. These systems are particularly helpful for giant vehicles, because it allows them to be more nimble and make turns that otherwise would require a lot more… negotiation in a giant land yacht.

So it’s possible that Rivian is only working on rear wheel steer by wire here, but we’d like to think there’s a chance it’s working on steer by wire for the full vehicle.

We also don’t know if this would show up on all of Rivian’s vehicles, or only on certain models – the R2 and R3 are in development, with R2 in pretty late stages, and the R1 just got a big refresh. But, perhaps even more interestingly (and very speculatively), VW has invested heavily in Rivian for technology help, so we wonder if we might end up seeing this in VW group vehicles, or Scout vehicles eventually…

BMW isn't wasting any time discounting its new 2026 EVs

Automakers are scrambling to push their EVs out the door before the $7,500 Federal tax incentive for EVs disappears — and BMW is no different, offering aggressive cash back, owner loyalty, and special financing rates on its just-released 2026 model year EVs.

BMW has a history of offering solid loyalty incentive programs on its EVs in early summer to clear the tail-end of the model year and make room for the incoming builds, but CarsDirect is reporting some unusual loyalty deals from the brand that seem to suggest BMW is keen to capitalize on a spike in EV sales ahead of the Federal tax incentive’s looming cancellation in September.

BMW dealers now have the choice of adding an additional $1,000 loyalty contribution on select 2026 EVs. The i5 and i7 are offered with $1,000 and $4,000 loyalty bonuses, respectively, meaning if you drive a BMW and your dealer opts to tack on the extra bonus, you could save $5,000 on a 2026 i7. These loyalty programs are good when buying or leasing.

There’s also a $1,000 conquest bonus available for drivers of eligible EVs and PHEVs from other brands. This program is stackable with other offers.

CARSDIRECT

Like other EV brands offering huge lease incentives, BMW customers will see the largest rebates on new BMWs when leasing. Now through September 30th, 2026 BMW i5, i7, and iX models are available with a stout $9,900 lease credit, while the bigger BMW XM comes in with a slightly lower, but still substantial $7,500 lease incentive.

Big deals on big BMW i7 sedan

People who prefer to own their vehicles once the payments are up can still score a great deal on an objectively excellent 2026 BMW i7 luxo-cruiser, thanks to the previously mentioned loyalty bonus if they’re previous customers plus a $7,500 Loan Credit that anyone can get when financing their new i7 with the brand’s captive financing company. BMW Bank offers financing rates as low a 3.99% for up to 60 months on the 2026 i5 and i7 sedans, as well as the iX crossover, as well as 4.99% APR 60-month rate on the high-performance XM plug-in hybrid.
