Nuclear Power Stations: Closures
The question
To ask the Secretary of State for Energy Security and Net Zero, what assessment he has made of the potential impact of the scheduled closure of Torness, Hartlepool and Heysham nuclear power stations on baseload electricity supply.
Answered by Michael Shanks
Currently, nuclear generation provides around 15% of total electricity. The four Advanced Gas-cooled Reactor (AGR) stations at these locations are operating beyond their original forecasts, with current expected closures being planned well in advance by the operator (EDF). In September 2025, EDF announced Heysham 1 and Hartlepool power stations are now scheduled to generate until March 2028, an extension of 12 months. Heysham 2 and Torness are both scheduled to generate until March 2030. EDF’s ambition is to continue electricity production at its four generating AGR stations for as long as it is safe and commercially viable to do so and will keep station lifetimes under review.
Energy security is a priority for the government, and we work closely with the National Energy System Operator (NESO), Ofgem and key industry stakeholders to constantly monitor electricity supply against forecast demand to ensure electricity operators have the right tools to respond to market signals.
