EDF confirms plans to keep turbines turning at Heysham 1 and Hartlepool power stations

By EDF | Posted March 09, 2023
  • Heysham 1 and Hartlepool are forecast to generate zero-carbon electricity for 2 years longer, supporting energy security, reducing demand for imported gas and lowering carbon emissions 
  • EDF has already invested over £7billion in the UK nuclear fleet since 2009 to extend the generating lifetimes of the existing fleet, delivering over 30% more output than originally forecast 
  • Keeping the existing stations generating longer also helps preserve vital nuclear skills as the UK aims to rebuild its civil nuclear capacity 

Two nuclear power stations in the North of England are expected to keep generating zero-carbon electricity for longer, helping deliver more energy security for the UK. 

Heysham 1, in Lancashire, and Hartlepool, in Teesside both mark 40 years of generation this year. In 2009, when EDF took responsibility for the fleet, they were due to end generation in 2014. EDF invested significant resources to enable the forecast to move to 2024. This has now been moved out by a further 2 years to March 2026. 

The decision has been made after a rigorous review by EDF of the technical and commercial cases for life extension. 

In particular, positive inspections of the graphite reactor cores during 2022 have increased confidence that the stations can generate for longer and continue to meet stringent regulatory standards. 

Matt Sykes, Managing Director of EDF’s Generation business said: “Supplying zero-carbon and affordable electricity, whatever the weather, has never been more important than right now. Our ongoing investment and careful stewardship of the UK nuclear fleet since 2009 has allowed us to make today’s decision and helps support the UK’s energy security at this challenging time. 

“As well as helping the UK reduce its use of imported gas, it is also great news for the 2,000 skilled people whose jobs are supported by these sites and will help preserve valuable technical and operational skills that will be critical as the UK seeks to re-build its nuclear capability.” 

The additional 29TWh of electricity these stations could generate over that 2-year period could help to displace 6billion cubic metres of gas. The carbon avoided from this displacement is 10million tonnes, like taking 5m cars off the UK’s roads for a year. 

Since taking responsibility for the existing UK nuclear fleet in 2009 EDF has invested more than £7billion to support extended operating lifetimes and help UK energy security.  Output from the fleet has been more than 30% above what was expected when EDF took on the fleet. Over the next five years (2023-27), the aim is to invest more than £1.5billion to sustain safe and reliable generation, alongside preparing for and delivering defueling. 

 


 

Notes to editors 

  • This latest lifetime extension is now EDF’s most likely view and the market has been notified accordingly. It has been made on a plus 1, minus 1 basis, meaning there is an ambition to continue generation for a further 12 months past the March 2026 date but that there is still a risk that the new date set today may not be achieved.  
  • These dates are forecasts, and the precise dates will be determined by the results of regular graphite inspections and how those results are interpreted within EDF and by the independent regulator, the Office for Nuclear Regulation. 
  • End of generation dates are kept under regular review and revised based on the best information available at the time.  
  • Two previous reviews have already seen these sites have their generating lives extended by 10 years. At the time of acquisition, in 2009, the stations were due to stop generating in 2014. In 2010, this was extended by 5 years to March 2019. In 2016, this was extended by a further 5 years to March 2024. 
  • Decisions on end of generation dates for EDF’s nuclear power stations in the UK are independent of the regulator or government and are taken by EDF’s licensee board following recommendations from EDF Energy Nuclear Generation Limited’s Executive. They are then endorsed by relevant senior Boards and, if needed, shareholders.  
  • The decision on the change of end of generation date for Heysham 1 and Hartlepool was taken following a series of EDF executive, board and shareholder meetings on 9 March 2023.  
  • The estimated end of generation dates for Torness and Heysham 2 remain unchanged at March 2028.

About EDF

EDF is driving the transition towards An Electric Britain – a secure, affordable, low-carbon future for everyone. As Britain’s biggest generator of zero carbon electricity, we are investing more than £100 million weekly in Britain’s electricity infrastructure. We supply millions of customers with electricity and help homes and businesses switch to electricity for heating, transport and industrial processes.

We operate five nuclear power stations and more than 35 onshore wind farms and three offshore wind farms. Since 2009, EDF has invested almost £9 billion in the nuclear fleet to improve reliability and extend station lifetimes. The five generating stations currently supply about 12% of the UK’s electricity demand.

EDF is building the UK's nuclear renaissance with the construction of a new nuclear power station at Hinkley Point C. We are a minority investor (12.5%) in and major supplier to a replica plant at Sizewell C in Suffolk. Hinkley Point C and Sizewell C will provide low carbon electricity to meet 14% of UK demand and power around 12 million homes. EDF Group companies Framatome and Arabelle Solutions have a presence in the UK and manufacture critical equipment such as reactor pressure vessels and turbines.

EDF is enabling its 5 million customers, both in business and at home, to choose electric solutions that save cash and carbon, whether it is buying an electric car, generating and storing electricity, selling energy back to the grid or installing solar panels or a heat pump. In 2025, EDF’s Customers business was ranked as one of the Sunday Times’s Best Place to Work.

It is also one of the UK’s leading developers of renewable energy through EDF power solutions UK and Ireland. We have more than 2GW of renewable generation in operation and over 10GW in construction, planning and development across a range of technologies including onshore and offshore wind, solar and battery storage.

We are one of the largest suppliers to British business and a leading supplier of innovative energy solutions that are helping businesses become more energy independent. In addition, the company’s energy services business, Dalkia, is one of the UK and Ireland’s largest technical service providers.
