Gas warning: not enough to meet demand
The National Grid, responsible for running Britain's gas and electricity pipes and wires, yesterday issued an unprecedented warning that the country was in danger of not having enough gas to meet demand.
It issued its first-ever "gas balancing alert" to the market, telling traders that gas demand might have to be reduced, initially for businesses. The move sent wholesale prices spiralling up fourfold.
