National Grid calls on UK industry to curb peak electricity use.

FT: National Grid calls on companies to consider curbing their electricity use between 4pm and 8pm on winter workdays next year. This is a clear sign of the urgency of Britain’s looming energy supply shortage. Meanwhile Ofgem says that by 2015/16, electricity margins – the safety cushion of spare generating capacity – are to tighten faster than previously expected, to as low as 2 per cent. / Supply disruptions “imminent or likely” are not likely, Ofgem says, but said the probability of such disruptions will increase from one in 47 years now to around one in 12 years for 2015/16.
