divebuddy I am not saying it is a bad thing, unfortunately it is inevitable. Good or bad. The electricity supply situation is going to get much worse before the first of the new nuclear stations come online in 20 years or so.
The maximum load is never supposed to be more than 75% of the generating capacity, but only a few weeks back in the hot weather, demand mainly due to air conditioning, peaked at 98% of the maximum generation capacity.
This was on a summer lunch time NOT in mid winter when such peaks normally happen! If there then had been just a minor breakdown in the UK generating capacity we would have had a 'cascade' of power cuts all over the UK. A cold winter will produce the same situation!
