HC Deb 10 December 1968 vol 775 cc67-8W
32. Mr. Ridley

asked the Minister of Power what estimate he has made of the saving in capital expenditure on the basis of the margin of electricity generating capacity over maximum demand in average cold-spell weather in 1968–69 being 17 per cent. and not 20 per cent.

Mr. Mason

The 17 per cent. margin is a planning assumption for purposes of determining the generating plant programme for six years ahead. It will inevitably be exceeded in some years and not reached in others, so an estimate of a notional saving would be misleading.
