The fractional contribution to electricity made by a 3 MW windturbine in the Netherlands and the UK
To calculate the yearly yield of 3 MW Wind turbines as a 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. For the UK that number is about 39,509 MW, roughly three times more. For both countries we can use the same productionfactors (or capacityfactors): For the onshore turbines 0.25 or 25 % and for the offshore turbines 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 parts in a hundred thousand of the national consumption. That proportionate yield in the UK is three times less, 0.75 / 39,509 = 0.000,019 or 1.19 parts in a hundred thousand 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 parts in a hundred thousand of national consumption and in the UK 1.08 / 39,509 = 0.000,027 or 2.7 parts in hundred thousand. 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 Wind turbines are built on a certain location. See chapter II2.
