In the rural areas of the Netherlands with no great concentration of power consumers, a relatively modest distribution network with a "medium voltage" of 10 kV, and a grid and switching station which are also not too heavy, is all that is needed for undisturbed electricity supply. However, if two or three giant Wind turbines of 2 MW or even 3 MW Wind turbines are integrated, the grid is burdened with wind power that varies between four to six MW and zero MW. This considerably varying power must find its way somewhere, thus causing overload to the electrical network, for which the ordinary security device is not prepared, and also the modest switching station will probably have to be reinforced. Unless all of that is done, for a lot of money, there is a high probability of frequent cuts in the supply.
Now you must not think this gloomy story is an exaggeration. Ask the managers of these kinds of grids in the rural areas for their experience after having been taken by surprise by the construction of Wind turbines. They will most likely tell you that the number of failures in the grid has gone up uncontrollably since Wind turbines became operative in their neighbourhoods. Are these inconveniences and extra technical facilities ever taken into account when establishing the price of such a wind project? I would think not. Do ministers, mayors and city councillors have any knowledge on this? That is also most unlikely. They prefer to keep to what "politics" asks and expects from them, in order to avoid awkward discussions with their political bosses.
