Warning from Ofgem: Lights may fade this winter

National Grid may struggle to balance supply and demand of electricity; resulting in fading lights.   UK energy regulator, Ofgem has raised concern that in the event of a harsh winter in 2015,

This month Ofgem divulged their electricity capacity estimates for the next two years- if meteorology reports foretelling a harsh winter are true, lights could be dimming for a total of nine hours. 

Ofgem's report states: "the margins of surplus electricity are still expected to drop to their lowest level in 2015-2016, resulting from closure of old power stations. After this period, the margins are expected to improve as new power stations are introduced."

The estimates for electricity capacity are based on data from National Grid in conjunction with Ofgem's own analysis.
