asked the Secretary of State for Energy what was (a) the time and date of the maximum simultaneous demand for electricity in the area of the Central Electricity Generating Board in the current winter, (b) the amount of maximum simultaneous demand and (c) the installed generating capacity of the Central Electricity Generating Board at that date.

I am advised by the CEGB that the maximum system demand on the CEGB system in England and Wales this winter of 44219 MW occurred at 1700 hours on Monday 14 January 1980; load lost due to the effects of the steel strike at that time was estimated to be 880 MW. The total declared net capability of the board's generating plant on 14 January was 56765 MW s.o; of this 49,000 MW was actually usable at the time of peak demand.
