Azps,

I think you misunderstood my posting, or perhaps skewed my meaning.  I was not considering the end-user taking more power.  Every kWh that Dinorwig, per eg, gets from cheaper night generation is a kWh not needing to come from fossils.  Reduced energy use should be everyone’s priority.  Note I said energy, not elecrical energy.

The same amount of energy over the year (ie less power but for longer duration) won’t make for more expensive power, as we are not considering generated power that is used onboard the turbine.  I can understand that power may well be consumed for each start-up, but that should be offset by possibly fewer stops due to low wind speed.  An extra 120kW even when otherwise only generating at 1MW is worthwhile, surely?  

That extra (surplus) ~12% swept area (compared with current 10MW machines) represents quite a lot of power available, even at low wind speeds and obviously increases the generation by that same percentage all the way to maximum output.  Turbine operators are always hunting for even than less than 1% gains in overall output!

I wonder how many hours in a year turbines are generating at full name-plate rating?  Increasing that number by 12% is unlikely to exceed all the other running hours at an increased 120KW? Plus the other hours when the turbines might be stood idle due to low wind (maybe this never occurs off-shore, but I expect it occurs occasionally as wind generation has been less than 100MW too often).

GarethC,

The type of renewable energy is simply a commercial consideration.  Return on investment is important, but when the government deny acquisition of extra land-based wind renewables, what alternatives are there, for the investors looking for a profitable income?

i have a relative who is involved in wind farms in the UK who told me certification costs of a new wind turbine are the the order of £10 Million

Its often worth popping on to the Crown Estate interactive offshore wind farm map as that shows live generation statistics for each and every offshore farm around the UK and therefore tells us how much the site is generating vs full nameplate capacity

https://www.thecrownestate.co.uk/en-gb/our-places/asset-map/

So for example, Galloper, at 9am this morning, is winding out 107MW. Total capacity of the farm is 352MW so it's running at 30%.

And Andrew's (azps) site has average load factor data.

Hornsea 1 was just recording 158% of its maximum capacity!

The second video in this article shows a lot of people beneath the blade, giving a better feel for its size.

The prototype turbine has delivered its first power.
