Centrica, in partnership with EDF, has announced the extension of the operational lives of its four advanced gas-cooled reactor nuclear power stations.
The extensions will see Heysham 1 and Hartlepool generating electricity until March 2027, while Heysham 2 and Torness will continue until March 2030.

These extensions will add 9TWh [terawatt hours] to Centrica’s electricity generation volumes between 2026 and 2030.
The move supports the UK’s baseload power generation, aligning with the country’s net zero ambitions and maintaining grid stability amid increasing renewable energy integration.
The decision followed a detailed review process to ensure the power stations’ extended lifetimes do not compromise safety.
Centrica Group chief executive Chris O’Shea stated: “At a time when energy security is uppermost in people’s mind, I’m delighted that we’re able to extend the operating window of the UK’s nuclear fleet, which is critical to UK security of supply and the country’s net zero ambitions.

By GlobalData“In an energy system that is becoming ever more intermittent, baseload power generation that doesn’t depend on the sun shining and the wind blowing is essential to keeping the lights on.
“Today’s extensions to the lives of the zero carbon Heysham 1, Heysham 2, Hartlepool and Torness nuclear power stations are a positive reflection of the valuable investment that Centrica and EDF have made in these plants.”
Further extensions may be considered, pending additional reviews, with any new decisions to be communicated publicly.
O’Shea continued: “We’re delighted that a further extension was possible which allows us the time necessary to develop other zero-carbon dispatchable electricity generation options such as new nuclear and hydrogen-fired generation. We must move at a faster pace to ensure that these replacement technologies are deployed in time.”
Centrica emphasises the importance of these extensions in supporting the UK’s energy transition.
