    Aye! so did I, and when I was on the local mountain rescue team in the late 60s, we used to use those massive pylons as reference points, as they were even shown on our maps?

    Exactly the point I was trying to make, It does not actually generate electricity per se. It is just a poor (and very expensive) way of storing a reserve of electric for later when there are peak demands.

    These types cannot be classed as power stations, As without power from another power station they simply would not produce any electricity.
