Two of Britain’s ageing nuclear power plants will stay open for two years longer than expected to reduce the risk of an electricity supply crunch.

EDF, the French state-owned energy group that operates Britain’s five remaining nuclear power plants, said Heysham 1 in Lancashire and its Hartlepool plant in Teesside were likely to remain in service until March 2026, instead of closing next year.
