To compare the yearly yield of 3 MW windturbines as part of the national consumption of electricity it is necessary to know that consumption .
The yearly consumption in the Netherlands is produced with an average aggregate power of all the powerstations of 13,000 MW. That number is for the UK about 39,509 MW, roughly three times more.
We reckon for both countries with the same productionfactors (or capacityfactors): For the onshore turbines 0,25 or 25 % and for the offshore turbines with 0,36 or 36 %
That means that an onshore turbine in the Netherlands has a yield of
0.75 / 13,000 = 0.000,006 or six hundredthousandth part of the national consumption.
That yield in the UK is three times less, 0,75 / 39,509 = 0.000,019 or
1.19 hundredthousandth parts of the UK consumpition
For a 3 MW offshore windturbine in the Netherlands the yield will be
1.08 / 13,000 = 0.000,008 or eight hundred thousandth parts of national consumption and in the UK 1.08 / 39,509 = 0.000,027 or
2.7 hundredthousandth part.
With these numbers one can calculate the total yield for both onshore an offshore windfarms. As you know from previous information in this treatise: the total yield of electricity is produced with hundreds of variations of the power, resulting in a considerable risk for the reliable and undisturbed functioning of the national grid. Even when only two or three windturbines are built on a certain location. See chapter II 2.
