The French-owned operator of all four sites has now pledged a further £15bn for UK nuclear and renewable projects.
EDF was responsible for generating almost one-quarter of all electricity used in the UK during 2025. This mainly came from the company’s five British nuclear sites, including Sizewell B in Suffolk, Heysham in Lancashire, and Torness, Scotland.
The impressive production rate makes the firm the UK’s largest electricity generator of zero carbon power. This is in spite of a 12% fall in overall output, largely due to an extended outage at Hartlepool, Teesside. As a result, corporate earnings were down from £2.9 billion to £1.9 billion, with the fall in value of nuclear energy also having an impact.
Nevertheless, EDF has now pledged £15 billion for nuclear, wind and solar projects across Britain over the next three years. A substantial proportion of which will go towards bringing the reactor at Hinkley Point C online. This follows a £5 billion investment during 2025, which in itself was up 30% compared to the previous 12 months.
‘EDF is continuing to invest heavily in powering, supplying and building an electric Britain,’ said EDF UK Chief Executive, Simone Rossi. ‘Our UK strategy is to deliver a long-term nuclear and renewables generation business, and to meet the evolving needs of our customers as more and more transition away from fossil fuels to using cleaner, more secure and affordable electricity.’
Last week, Environment Journal ran an in-depth feature on how companies can reframe sustainability communication and messaging well beyond carbon reporting. This includes relaying progress without the risk of green-hushing and proven ways to guarantee credibility and authenticity.
