Gamechanging Vestas V164 Wind Turbine Continues Groundbreaking Development (8MW Wind Turbine!)

October 3rd, 2012 by  

Vestas Wind Systems has been at the heart of the wind industry’s development across the world and continues in that role with the development of its V164 platform, which is not only on track for prototype deployment but has recently seen a technological development allowing the turbine to now reach a capacity of 8 megawatts!

“The V164 platform was from the very beginning developed with a possible potential of increasing the turbine size,” said the Danish company in its press release. The development of the technology behind the V164 has now reached a point where an 8MW version will offer low-cost energy while leaving the reliability and structural integrity of the turbine unchanged.

“As we progressed in the technology development it was clear that an 8 MW version of the turbine will offer lower cost of energy and at the same time keep the reliability and structural integrity of the turbine unchanged,” said Executive Vice President and CTO, Anders Vedel.

Vestas V164 Nears Completion and Increases to 8MW

The development of the new V164 turbine is progressing according to schedule, with several main components currently nearing completion:

  • The blade mould for the 80-metre blades is ready at Vestas’ testing facilities on the Isle of Wight, UK, and the production of the first blade for testing purposes will be initiated during Q4.
  • The prototype hub has been cast and is ready for testing.
  • The generator and gear box will be ready for testing in Q1 2013.


“We are getting closer to installation of the prototype every day, and it is very satisfying to see the first major parts of the V164-8.0 MW under completion,” said Vedel. “This turbine is truly going to be a game changer. When you stand beside the blade mould for the 80 metre long blades you can really sense the scale of the turbine.”

Vedel noted that the complete drivetrain will be tested at Vestas’ facilities in Aarhus, Denmark on a test bench currently being built to the purpose.

“Our capability to do in-house testing of the V164 gives us a competitive advantage. It improves the reliability of the turbine and thereby the business case certainty for the customers. The test bench will be commissioned in January 2013.”

The company are still targeted for installation during 2014.

    any idea about the Kwh price for electricity of this wind turbine?

    • Luke

      I’m pretty sure that the manufacturing price of this turbine is a closely guarded secret. We’ll have to wait to see it used in projects before we get an idea of the kWh price…

  • Luke

    Wow! The first 8MW turbine… I’ve been waiting for this for a long time… fantastic news!

    They must’ve squeezed an additional megawatt of power out of the V-164, since the video press release I saw a few months ago clearly showed this turbine being 7MW…

  • dynamo.joe

    How do you deliver an 80m blade to a construction site? Is this for off-shore only?

    • Luke

      Yep – it’s an offshore turbine only.

      2 helicopters

      • Ronald Brak

        No, one helicopter, using the windmill blades as a very large rotor.

        • Bob_Wallace

          You thinking that they can fly the turbine into place?

          • Ronald Brak

            Well, no, I don’t think using the wind turbine blades as a rather large helicoper rotor would be practical. That said, if one wanted to build them on land, it would be possible to build a mobile factory to cast the blades on site. Just how practical that would be, I don’t know.

          • Bob_Wallace

            Gosh, I thought we were exchanging “funnies”.

            I could see someone wearing Snoopy goggles flying the complete turbine into place….

            On a more serious note I do wonder why onshore blades are not flown to the site at times. We had a local wind farm curtailed because a land route would have meant moving one or more historical houses.

            Around here we use “flying cranes” regularly to lift massive tree trunks out of less accessible places. One would think an hour of chopper time would be less expensive than moving buildings, taking down power poles, etc.

          • Ronald Brak

            It’s a good question. I do know that it would be massively expensive to do here as I don’t think we have the heavy lift capacity. And the length of a blade would make it awkward to transport by helicopter. But why they can’t do it in places that have experience with that sort of thing, I don’t know.

          • Bob_Wallace

            When they haul tree trunks (and I’m talking long and large diameter, really big firs and redwoods stripped of branches) they fly them vertically, not horizontal. The issue would be whether the blades are too heavy to lift and how to hand them off to the turbine.

            I would imagine that a crane could capture and do the final positioning. But I’m just guessing….

          • Sébastien DdC

            Just a guess, but between the speed of the helicopter and the wind, the loading on the blades may start to be too important to ensure proper control of the machine.

            Another possibility is that this method would need to be certified, which manufacturers would only do if the business asks for it.

            Finally, for an 80m long blade, the mass must approach maybe 40? 50 tonnes? (approximation based on, which few helicopters (if any) can carry.

          • PriSub

            hey Sebastien… how’s life?

    • My guess is the mfg facility is located at a port where the blade can be loaded directly onto a ship that delivers it to the off-shore site. I know Voith builds a specialty off-shore wind farm installation and service vessel.
