EDF is a major French energy group, maker of nuclear power and operator of generation and supply assets across Europe.
Sizewell B will continue generating electricity until 2055 after a 20-year life extension, with a contract for difference guaranteeing 370.50 per megawatt-hour from 2035. The move aims to shield billpayers and secure thousands of jobs and clean power, while backing new nuclear projects.
The National Energy System Operator has issued a margin notice for Thursday evening due to extreme European temperatures, marking the third such notice this year. The move signals a higher cushion between demand and supply, as heat drives up electricity use and strains generation.
