A few years in the past after I visited the big wind turbine take a look at website at Østerild in northern Denmark, I questioned how huge this stuff would find yourself being. It appears the effectivity restrict is about to be inside attain, and whereas this will not be the case in technical phrases, it simply may be in manufacturing, logistical, and financial phrases.
Two Main Wins For Vestas
This week Vestas introduced two main orders in Germany and Lithuania. The press launch for the German order states that Vestas will ship, fee, and repair eight V162-5.6 MW wind generators. They’re about the identical measurement as those I noticed examined at Østerild. Sulai Fahimi, Vestas Vice President of Gross sales Central Europe, states: “We’re more than happy to have been chosen to provide our onshore generators for the Dollenkamp challenge because it highlights the significance of onshore wind within the German power transition.”
The press launch for the Lithuanian order states that Vestas will ship, fee, and repair 14 of the marginally extra highly effective V162-6.2 MW wind generators. The 2 orders signify a mixed capability of 152 MW. Jens Pinderup, Vice President of Gross sales East at Vestas NCE, states: “All the space provides big potential for wind power tasks, and we’re proud that our EnVentus wind generators provides a aggressive answer for our clients whereas serving to to decarbonise the power system within the Baltic area.”
Is Larger At all times Higher?
These Vestas V162 generators with a rotor diameter of 162 meters (531 ft) is likely one of the greater fashions in Vestas’ onshore catalog, solely barely smaller than the V172 which is best suited to decrease common wind speeds. Nonetheless, these machines appear dwarfed by the 15 MW monster Vestas provides offshore, the V236. So, will onshore generators finally be as huge as offshore generators?
A bit in dr.dk has some attention-grabbing views on the topic. The wind turbine trade says the world wants extra — not greater — generators. Deputy Director of Vestas Morten Dyrholm states: “Now we have reached a degree the place we should take a break within the growth of bigger generators. We must always not preserve sending greater and larger generators onto the market. There’s a must mass produce and standardize.”
In keeping with Sydbank Denmark, the wind turbine trade must get again to earning profits quick. Right here is its checklist of how a lot the large gamers misplaced in 2023:
Siemens Gamesa: 385 billion DKK ($56.92 billion)
Basic Electrical: 37 billion DKK ($5.47 billion)
Nordex: 10 billion DKK ($1.48 billion)
Vestas: Expects no loss/acquire, however misplaced 11.7 billion DKK ($1.73 billion) in 2022
Fairness evaluation supervisor Jacob Pedersen from Sydbank states: “There is no such thing as a doubt that if the wind turbine producers are to get again on monitor, in order that they will spend money on extra manufacturing services, in order that we are able to get extra wind generators — then it additionally requires that this arms race with consistently making greater wind generators involves an finish.”
Henrik Stiesdal, one of many pioneers within the Danish wind turbine journey, former head of growth at Bonus Power and former technical director at Siemens Wind Energy, proposes that EU laws ought to assist the trade to restrict the peak of wind generators. Particularly, Henrik Stiesdal proposes a most top of roughly 300 metres (984 ft). “The authorities need to say that there’s an higher restrict: make them cheaper and extra environment friendly, however don’t make them greater than a sure measurement,” he says.
On the trade group Inexperienced Energy Denmark, deputy managing director Jan Hylleberg has sympathy for the proposal. However he doubts that’s sensible. “I discover it tough to see how [this proposal] might perform in a sector as world as this,” he says.

I do not like paywalls. You do not like paywalls. Who likes paywalls? Right here at CleanTechnica, we applied a restricted paywall for some time, nevertheless it all the time felt mistaken — and it was all the time powerful to determine what we should always put behind there. In idea, your most unique and finest content material goes behind a paywall. However then fewer folks learn it!! So, we have determined to fully nix paywalls right here at CleanTechnica. However…
