Here’s why the first commercial spiral-welded wind turbine tower is a game-changer
The first commercial spiral-welded wind turbine tower has begun operation – here’s what it is and why it matters.
The spiral-welded wind turbine tower was built by GE Renewable Energy and wind turbine producer Keystone Tower Systems. And after years of collaborating with the US Department of Energy, they installed the 89-meter-tall (292-foot-tall) tower on the GE 2.8-127 wind turbine.
The US Department of Energy explains what spiral welding is:
Spiral welding is when the steel used to make the tower is curled into a cylinder; essentially, these towers are built from meters-wide steel plates.
The technique requires only one machine to construct a tower section, and it can produce towers up to twice as tall and 10 times faster than conventional towers.
Keystone designs and builds its own custom spiral welding wind turbine tower manufacturing equipment in Denver. The manufacturing process uses coil steel – flat-rolled steel that’s been coiled up into a roll or coil shape – and Keystone’s machine allows tapered towers with variable wall thickness to be manufactured from constant width sheets of steel.
The manufacturing equipment completes the joining, rolling, fit-up, welding, and severing of a tower section – and that results in the continuous production of steel tower shells:
And here’s why spiral-welded wind turbine towers are going to be impactful: Keystone says it can make the lightest, lowest-cost, and most structurally optimized towers in the wind turbine industry.
GE and Keystone made their inaugural tower at Keystone’s factory in Pampa, Texas, in the state’s Panhandle. The brownfield factory was built at an idled factory that used to make oil and gas drilling equipment. The new wind turbine factory will return nearly 200 manufacturing jobs to the region.
Keystone is also developing mobile factories capable of building taller towers directly at wind sites.
Production is now being ramped up of spiral-welded towers, with additional deliveries targeted for the first quarter of 2023. They’ll make more towers for the GE 2.8-127 turbine, and they can be used interchangeably with GE’s conventional 89-meter-tall tower. The spiral tower has received a component certification from TÜV NORD for a 40-year lifetime.
Eric Smith, Keystone’s cofounder and CTO, said:
I’m very proud of the years of hard work our team has invested in developing and scaling up tapered spiral welding.

Baidu- and Geely-backed JiYue brand unveils ROBO X EV that goes 0-100 km/h in under 1.9 sec
JiYue, a Chinese EV brand focused on delivering all-electric “robocars” to the masses, has unveiled its latest model, and it’s quite a deviation from its previous EVs—but in the best way. Earlier today, JiYue launched the ROBO X supercar, designed for high-speed racing. By high speed, we mean 0-100 km/h acceleration in under 1.9 seconds. My mouth is watering.
JiYue has only existed since 2021, when parent tech company Baidu announced it was expanding from software development into physical EV production, joining forces with multinational automotive manufacturer Geely.
The new “robotic EV” marque initially launched as JIDU with $300 million in startup capital before garnering an additional $400 million in Series A funding, led by Baidu, in January 2022.
In August 2023, Geely took on a larger role in JIDU alongside a greater financial stake as the brand reimagined itself as JiYue, inheriting the JIDU logo and its flagship model, the 01 ROBOCAR.
In December 2023, Baidu and Geely unveiled a second model called the JiYue 07. It was born from JIDU’s ROBO-02 concept, which debuted in 2023 and was designed to compete against the Tesla Model 3 in China.
The 07 finally launched in China earlier this year with 545 miles of range. With an all-electric SUV and sedan on the market, JiYue has unveiled an exciting new entry in the form of a performance supercar called the ROBO X. Check it out:
JiYue’s new ROBO X EV is available for pre-order now
JiYue showcased its new ROBO X hypercar in front of the crowd at the 2024 Guangzhou Auto Show earlier today. Similar to previous models but with a unique spin, JiYue described the ROBO X as an AI smart-driving supercar that, for the first time, blends artificial intelligence and autonomous driving into a high-performance, race-ready EV.
When we say “high performance,” we mean a quad motor liquid-cooled drive system that can propel the ROBO X from 0 to 100 km/h (0 to 62 mph) in under 1.9 seconds. JiYue called the new ROBO X a “performance beast” with “the perfect balance of excellent aerodynamic performance and high downforce.” JiYue CEO Joe Xia was even bolder in his statements about the ROBO X:
For the next 20 years, the design of supercars will bear the shadow of Robo X. This is the best design in the history of Chinese automobiles today, and it is a landmark presence.
Fighter-style airflow ducts bolster the EV’s aerodynamics, efficiency, and overall posture. Per JiYue, the two-seater ROBO X is expected to deliver a maximum range of over 650 km (404 miles).
The new supercar features falcon-wing doors, a carbon fiber integrated frame, and a professional racing HALO safety system offering 360° of support. The interior features an AI smart cockpit with SIMO real-time feedback to give drivers an immersive racing experience.
Furthermore, JiYue said the vehicle will utilize parent company Baidu’s Apollo self-driving technology, which could make it the first electric supercar to apply pure-vision ADAS technology that enables track-level autonomous driving.
Following today’s unveiling of the ROBO X, JiYue has officially opened up pre-orders in China for RMB 49,999 ($6,915). That said, reservation holders will need to be patient as JiYue shared that it doesn’t expect to begin mass production of the ROBO X until 2027.
What do you think? Will people be talking about the ROBO X for the next 20 years?

- West Texas Intermediate December contract: $68.56 per barrel, down 14 cents, or 0.2%. Year to date, U.S. crude oil has shed about 4%.
- Brent January contract: $72.36 per barrel, down 20 cents, or 0.28%. Year to date, the global benchmark has lost nearly 6%.
- RBOB Gasoline December contract: $1.99 per gallon, up 0.46%. Year to date, gasoline has fallen more than 1%.
- Natural Gas December contract: $2.70 per thousand cubic feet, down 2.98%. Year to date, gas has gained more than 4%.
The International Energy Agency has forecast a surplus of more than 1 million barrels per day in 2025 on robust production in the U.S. OPEC revised down its demand forecast for the fourth consecutive month as demand in China remains soft.
A strong dollar also hangs over the market, as the greenback has surged in the wake of President-elect Donald Trump’s election victory.
