Torness Life Extension
Torness, East Lothian, Scotland, UK · Operations 1988-2028 (original), extended to 2030 · £1.2bn (investment across 2026-28 for reliability and output)
The judgement call
Account-gated at launchTorness, along with Heysham 2, received life extensions to 2030, contributing significantly to UK energy security and low-carbon electricity generation. - The extensions are subject to intensified inspections due to issues like graphite core cracking, highlighting the challenges of managing aging AGRs. - A £1.2 billion investment across 2026-28 is planned to boost reliability and output during the extended operational period.
Key engineering challenges
Demonstrating the long-term integrity of critical plant components, particularly the graphite core, given the discovery of cracks. - Managing aging infrastructure and replacing components to ensure continued safe operation. - Addressing regulatory requirements for extended operation and safety case updates. - Intensifying inspections for cracks to ensure continued safe operation.
