Seems a rather strange idea now but back in 1984 during the miners’ strike, we were told to fire up as many electrical appliances as possible between 6pm and 6.30pm to crash the national grid. The intention was to force a peak in consumption that would make the CEGB (Central Electricity Generating Board) burn more coal. This would reduce the stocks built up by the government to try and beat the strike. And so victory for the strikers would be hastened.
Well, that was the intention. In truth, I can’t remember anybody going for this ruse. If you did do tell me. Here was the postcard distributed at the time with instructions on what to do.
