EDF’s Heysham 1 and Hartlepool nuclear plants to operate for further 12 months

New Civil Engineer, 02 Sep, 2025 By Tom Pashby

The operational lives of the Heysham 1 and Hartlepool nuclear power plants have been extended by 12 months by their operator EDF………………

Hartlepool, Heysham 1, Heysham 2 and Torness all underwent reviews by EDF in December 2024 to assess how long they can continue to generate electricity. Heysham 1 and Hartlepool were scheduled to stop producing power in March 2027.

At the time, an EDF spokesperson explained to NCE that the best-case scenario for the Heysham 1 and Hartlepool power stations was that they could justify a one-year extension. However, that was caveated with a need to await the outcomes of “important inspection and safety case milestones”, which were due to be completed in 2025.

Those milestones have now passed and the results were positive for the power stations. When EDF’s executive and licensee boards met yesterday, 1 September, they gave approval to extend the lives of the nuclear stations, so Heysham 1 and Hartlepool will now likely operate through to at least March 2028.

A statement from EDF on 2 September said: “Heysham 2 and Torness, which are both scheduled to generate until March 2030, were not in scope for this review after a two-year extension was granted last year.”

EDF still hopes to see all four AGRs continue producing electricity for as long as possible, so it can be expected to conduct further reviews down the line, but these reviews do not have set dates for completion, the spokesperson told NCE……………………………………………………………………………………………………………………………

AGRs now well past their sell-by date’ – anti-nuclear campaigner

Nuclear Free Local Authorities secretary Richard Outram told NCE that the extension of the plants’ operating lives raises concerns about the possibility of graphite cracking.

“The EDF announcement is unsurprising. Although company bosses may crow a lot about the preservation of local jobs, the NFLAs suspect this is actually about the preservation of EDF’s bottom line,” he said.

“Given the parlous state of the French parent company’s finances, the intermittent output of the domestic fleet, and the vast overspend on Hinkley Point C, EDF has a clear incentive to keep open for as long as possible any nuclear plant in the portfolio which actually operates and generates profits.

“The NFLAs have previously expressed our concerns with the Office for Nuclear Regulation that these ageing AGRs are now well past their sell-by date, with graphite cracking being a real worry, as seen recently at the sister AGR plant at Torness.

“We shall continue to monitor the situation and ask challenging questions of regulators and the industry because public safety and environmental harm must never be compromised in favour of company profit.”………………………………………………. https://www.newcivilengineer.com/latest/edfs-heysham-1-and-hartlepool-nuclear-plants-to-operate-for-further-12-months-02-09-2025/
