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.”

Blades of the Haliade-X turbine stacked on top of each other at a site in the U.S. The past few years have seen companies develop increasingly large wind turbines.

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.”

As states push DER initiatives, $4,500 PG&E home battery rebate leads the way

As states push DER initiatives, ,500 PG&E home battery rebate leads the way

Rather than straining the grid, the batteries in EVs can actually help to stabilize the energy grid under heavy loads. PG&E gets that, and to encourage participation in its growing V2G programs, the utility is offering GM Energy customers in its territory up to $4,500 toward qualifying home battery systems.

Billed as a glimpse into the future of energy resilience, efficiency, and sustainability, Pacific Gas & Electric (PG&E) launched a pilot program with GM Energy in March, and the pilot’s success has led to more serious conversations around the topics of home batteries, EVs, and other distributed energy resources (DERs) on the national level.

Now that it’s had time to digest the results of the initial pilot, it seems like the Oakland-based utility is doubling down, the utility is expanding the program, encouraging participation with up to $4,500 in incentives for GM Energy customers willing to plug in.

While giving customers the ability to use their GM EV as a back-up home generator is an incredible, practical benefit to customers, it is just the beginning of what we can do to help encourage mass EV adoption with this technology … with the right incentives and policies in place, programs like this one could accelerate the shift toward a more distributed energy model.

GM ENERGY

As more states explore ways to meet renewable and distributed energy targets as they build up grid resilience – witness Illinois’ recent passing of SB25, which is slated to add 3 GW of battery storage by 2030 – incentives that encourage new participation in V2H, V2G, and VPP tech can help utilities meet those goals.

Tesla Optimus robot takes a suspicious tumble in new demo

Tesla Optimus robot takes a suspicious tumble in new demo

A new video surfacing from a Tesla demonstration in Miami this weekend shows the Optimus humanoid robot taking a nasty fall. But it’s not the fall itself that is raising eyebrows, it’s the specific hand movements the robot made on its way down, which strongly suggest it was mimicking a remote operator frantically removing a VR headset.

Humanoid robots are all the hype right now. Billions in investments are pouring in, and Elon Musk claims it will be a trillion-dollar product for Tesla, justifying its insane valuation.

The idea has been that with the advent of AI, robots in human form could use the new generalized artificial intelligence to replace humans in an increasingly larger number of tasks.

However, there are still many serious concerns about the effort, both at the ethical and technological levels.

Technologically, most humanoid robot demonstrations have relied on remote control by human operators – pointing to a remaining gap between the software and hardware.

We discussed how the robots at the “We, Robot” event were heavily teleoperated, despite Tesla not explicitly disclosing that fact to the public.

That was more than a year ago, and despite claims that Tesla has made “AI demos” of Optimus since, it appears the company still relies on teleoperation to control them during demonstrations.

The Tesla Optimus Miami Incident

This weekend, Tesla held an event called ‘Autonomy Visualized’ at its store in Miami. The goal was to showcase Tesla’s “Autopilot technology and Optimus.”

However, there was nothing “autonomous” at Tesla’s “autonomy” event.

Many Tesla fans were seen posting videos of a Tesla Optimus robot handing out bottles of water at the event. It was also seen posing for pictures and dancing.

On Reddit, someone posted a different video of the demonstration:

As you can see, Tesla Optimus moved its hands too quickly, causing some water bottles to drop to the ground. It then loses its balance and begins to fall backward.

But the most interesting part is that just before falling backward, both of its hands immediately shoot up to its “face” in a distinct grasping motion, as if pulling an object off its head.

The robot, of course, is not wearing anything on its head.

The motion is instantly recognizable to anyone who has used VR or watched teleoperation setups. It appears the human operator, likely located backstage or in a remote facility, removed their headset in the middle of operating the robot for unknown reasons.

Optimus faithfully replicated the motion of removing a non-existent headset as it crashed to the floor.

Here’s a look at how Tesla trained Pptimus with VR headsets in its lab:

Electrek’s Take

This is embarrassing, but not just because the robot fell. Robots fall; that’s part of the R&D process. Boston Dynamics blooper reels are legendary, and they never really eroded the company’s credibility.

The problem here is the “Wizard of Oz” moment.

The specific motion of removing the “phantom headset” destroys the illusion of autonomy Tesla tries so hard to curate.

Even recently, Musk fought back against the notion that Tesla relies on teleoperation for its Optimus demonstration. He specified that a new demo of Optimus doing kung-fu was “AI, not tele-operated”:

Musk said again during Tesla’s last earnings call in October:

“Optimus was at the Tron premiere doing kung fu, just up in the open, with Jared Leto. Nobody was controlling it. It was just doing kung fu with Jared Leto at the Tron Premier. You can see the videos online. The funny thing is, a lot of people walked past it thinking it was just a person.”

Musk keeps telling shareholders that Optimus will be the biggest product in history and that millions of units will be working in factories soon. But if they are still relying on 1:1 teleoperation to hand out water bottles right now, it feels like we are still far away from a useful generalized Optimus robot.

The electric crossover that could help save Nissan: meet the all-new NX8

The electric crossover that could help save Nissan: meet the all-new NX8 

After images of an the new mid-sized electric crossover were leaked by the Chinese MIIT, Nissan pulled the wraps off its all-new NX8 – and it looks so good, I’m wondering if it couldn’t spearhead the brand’s American turnaround.

Nissan has had a rough go of it in the US, if not, well – everywhere of late. And while we may all have our own ideas about what Nissan needs to do to turn its ship around and get back to its winning ways, one thing just about every auto industry analyst seems to understand is that, at its core, Nissan’s problem is a product problem.

It doesn’t have to be this way, though. Despite what the optics of cynically slapping a Nissan badge on a decade-old Mitsubishi platform and calling it a new Rogue might have you believe, Nissan happens to have fantastic, modern new products in its production pipeline – including the all-new NX8 BEV and EREV crossover shown here. There’s just one problem: Nissan’s comeback cars are all in China.

The “N” stands for Nice

Dongfeng Nissan, a Chinese-market automotive joint venture between Dongfeng Motor Group and Nissan, has been rolling out hit after hit in recent months, like the N6 (above), which sits between the Altima and Maxima, size-wise, and offers 112 miles on a full charge of its 21.1 kWh LFP battery before its 1.5L gas engine kicks on to keep the odometer rolling.

The N6’s stablemate, the all-electric Dongfeng Nissan N7 sedan, debuted a few months earlier to rave reviews and hot sales, too – moving more than 10,000 units in the model’s first three weeks on the market.

Like its sedan siblings, the all-electric version of Nissan NX8 crossover rolls on an 800V system architecture and features a CATL-sourced LFP battery pack with 5C ultra-fast charging technology (xC is how many you can charge in an hour, effectively, so 60 minutes divided by 5 = it can charge in as little as 12 minutes). That battery reportedly sends power to a single electric motor putting out either 215 kW (~290 hp) or 250 kW (~335 hp), depending on model.

EREV version of the NX8, meanwhile, features a similar setup to the N6, pairing a 1.5L ICE producing 109 kW (~145 hp) with a 195 kW (~260 hp) electric motor. Expect the NX8 EREV to get slightly less than the N6’s claimed 112 miles of electric-only range (Chinese cycle).

The NX8 is expected to reach its first customers in April 2026. Take a look at some of the firs official photos of the new Nissan crossover, below, then let us know how you think this would do in the US in the comments section at the bottom of the page.
