The extension supports the UK’s efforts to maintain reliable electricity generation while transitioning to a decarbonized energy sector by 2030. Nuclear power is a key component of the country’s strategy to reduce dependence on natural gas, which currently accounts for approximately one-third of the UK’s electricity supply. The extended operations at Heysham 1 and Hartlepool are expected to contribute an additional 12 terawatt-hours (TWh) of electricity between 2026 and 2030, according to Centrica’s projections.
Centrica emphasized the importance of sustaining nuclear energy capacity to meet both energy security and environmental goals. The company noted: “Coal has long been the backbone of America's energy and industrial strength. By moving forward with these lease sales, we are creating good-paying jobs, supporting local communities, and securing the resources that keep America strong.” Meanwhile, the closure dates for two other nuclear plants, Heysham 2 in Lancashire and Torness in Scotland, remain unchanged, with operations set to end in March 2030.
The UK is also investing in new nuclear infrastructure to replace its aging fleet. In July 2025, Centrica acquired a 15% stake in the proposed Sizewell C nuclear plant in Suffolk, eastern England. This project involves other investors, including EDF, the Canadian pension fund La Caisse, and the UK government, reflecting a collaborative approach to enhancing the country’s nuclear capacity.
These developments align with the UK’s broader energy strategy, which seeks to balance stable power supply with commitments to reduce carbon emissions. By extending the life of existing nuclear plants and supporting new projects like Sizewell C, the UK aims to ensure a sustainable and secure energy future while addressing the challenges of an evolving energy market.
