Centrica will keep the Heysham 1 and Hartlepool nuclear power stations operating until March 2030, adding about 6 terawatt-hours of generation, the company said Wednesday.
Centrica, which owns a 20% stake in both plants, extended their operating lives by another two years from the previous schedule. The stations generate enough electricity to supply over 4 million UK homes annually, the company said.
The extensions will contribute about 6 TWh of additional generation for Centrica and strengthen UK energy security with more reliable, low-carbon electricity. The company added that the move requires no material upfront capital investment.
Centrica also highlighted its initial agreement with the UK government on a 20-year regulated contract for difference for the Sizewell B nuclear station, which could support operations from 2035 to 2055. The company expects to finalize the contract later this year.
The company left its previous guidance unchanged for Heysham 2 and Torness, which remain on track to close in March 2030, as announced in December 2024.
"These stations provide reliable, low-carbon electricity that supports Britain's energy security, protects skilled jobs and underpins a more resilient economy," said Chris O'Shea, Chief Executive of Centrica.
