Vestas 15 MW Prototype Turbine Produces First Power

The title of this post, is the same as that of this article on

This is the introductory paragraph.

Vestas’ V236-15.0 MW prototype wind turbine has produced its first kWh after being fully assembled at the Østerild National test centre for large wind turbines in Western Jutland, Denmark.

The first of the four wind farms in the Hornsea wind farm complex to be developed is Hornsea One.

  • It has a capacity of 1218 MW.
  • It is comprised of 174 Siemens SWT-7.0-154, which each have a generating capacity of 7 MW.

If 15 MW turbines could have been used on Hornsea One, it would have more than doubled the generating capacity to 2625 MW.

But obviously, larger turbines have longer blades, so they may need to be placed further apart.

In Vattenfall Boosts Capacity For Norfolk Offshore Wind Zone, I write about how Vattenfall are increasing the size of their Norfolk wind farms, by proposing to use larger turbines.


Turbines will get larger and 15 MW turbines will be commonplace.

A possible advantage is that you only need sixty-seven turbines for a GW, as opposed to a hundred 10 MW turbines, so there are possibilities to optimise the most profitable way to build a wind farm.

  1. I do wonder when there will be a concerted plan to repower the first gen offshore windfarms given the exponential increase in turbine output that has been achieved

    • I could see this being done selectively.

      But these big turbines would have a bigger diameter.

      Some wind farms may have been built for upgrading, by spacing the foundations for larger turbines.

  2. […] The Danes may talk 62 MW, but that four times larger than one of the biggest today, that I wrote about in Vestas 15 MW Prototype Turbine Produces First Power. […]
