LONDON – EDF Energy plans to invest an additional £1.3 billion in its operational UK nuclear fleet to ensure stable energy output and enhance energy security, the company announced on Tuesday. The aim is to extend the lifespan of its nuclear plants in Britain, subject to regulatory approval, and make a final decision by the end of the year.
EDF Energy intends to prolong the operation of its four advanced gas-cooled reactor (AGR) plants beyond their initially planned retirement dates. These plants include Torness, Heysham 1 and 2, and Hartlepool. Additionally, the company is exploring the possibility of extending the lifespan of its Sizewell B plant, a pressurized water reactor-type plant, until 2055, which would be an extension of 20 years.
The decision regarding Sizewell B’s extended operational period is expected to be made in the coming year, contingent upon the establishment of a sustainable commercial model.
Mark Hartley, the Managing Director of EDF’s nuclear operations business, expressed the company’s commitment to maintaining the output of the AGR stations for as long as possible and extending Sizewell B until 2055.
In the UK, EDF Energy operates five nuclear plants that contribute significantly to the country’s electricity generation, while three others are in the decommissioning process.
Last year, the output of EDF’s UK nuclear fleet decreased by 15% from the previous year to 37.3 terawatt hours due to station closures and mandatory outages. However, the company aims to sustain output at 2023 levels until at least 2026.
EDF Energy’s decision to invest further in the existing nuclear fleet aligns with efforts to mitigate the potential energy shortfall as older power plants are decommissioned. Nuclear power plays a crucial role in the UK’s energy mix, providing low-carbon electricity and supporting the country’s transition to a more sustainable future.
By extending the lifespan of its nuclear power plants, EDF Energy aims to maintain the stability and reliability of the UK’s energy supply, contributing to climate change goals and energy security for the nation.
The investment reinforces EDF Energy’s commitment to nuclear power as a vital component of the UK’s energy infrastructure, while also exploring sustainable and cost-effective solutions for the long-term operation of its plants.
As EDF Energy awaits regulatory approval for the extension plans, the company remains dedicated to providing clean, low-carbon energy and positioning itself at the forefront of the UK’s energy transition.
