Powering an Electric Britain: EDF maintains position as Britain’s biggest generator of zero carbon electricity
- EDF generated 17% of the UK’s total energy supply
- The supplier has spent £4.3billion strengthening energy security and boosting jobs
- With the acquisition of Pod, EDF has expanded its offer to households
EDF remains Britain’s biggest generator of zero-carbon electricity, producing more than double the output of its nearest competitor and supplying 17% of the UK’s total power[i].
In its latest Sustainable Business Update, EDF highlights progress in building the infrastructure and solutions that will power Britain’s future. From large-scale generation to smart technologies for homes and businesses, EDF is enabling the electrification of everyday life, helping customers cut carbon and costs while strengthening the nation’s energy independence.
In 2024, EDF invested £4.3 billion to expand nuclear, wind and solar capacity, ensuring reliable zero-carbon electricity for millions. Alongside this, EDF is creating thousands of jobs and rolling out low-carbon solutions that make it easier for households and businesses to embrace an electric Britain.
Electrifying Britain: Building a Clean Energy Future
Operating 6GW of nuclear capacity, EDF’s nuclear operations avoided over 13 million tonnes of CO₂, equivalent to taking 6 million cars off the road for a year[ii].
The company also expanded its renewables footprint with 2GW of capacity and a 14GW development pipeline, and by 2035, EDF aims to deliver 10GW of generation and storage, helping customers avoid four million tonnes of carbon annually through solar, heat pumps, and EV infrastructure.
The company is also the only UK energy provider certified with the Biodiversity Benchmark, reflecting its commitment to nature-positive development across all managed land.
Making it easier for homes to save cash and carbon
To help customers take control of their energy use and reduce emissions, this year EDF expanded its offer to households with the acquisition of Pod, the market leader in home EV charging. Pod joins EDF Heat Pumps (previously CB Heating) and Contact Solar, all strengthening EDF’s ability to support electrification through low-carbon solutions to households across Britain.
Furthermore, EDF has launched a £30million Winter Support Package, offering vulnerable customers direct financial support through tailored one-to-one support, and expanding partnerships with charities and advice groups. It is also spending £119m on the Energy Company Obligation (ECO) and the Great British Insulation Schemes (GBIS) to improve energy efficiency for households.
Simone Rossi, UK CEO of EDF, commented: “Britain’s energy future depends on secure, affordable and clean electricity. That’s why in 2024 we continued to be a net investor in Britain, spending £4.3 billion on strengthening its energy security and boosting jobs, while helping households and businesses cut costs and carbon. An Electric Britain isn’t just EDF’s ambition it’s a shared journey for us all.”
Over the last year EDF has reached additional significant milestones, including:
- Investing £2 for every £1 earned since 2018, demonstrating our long-term commitment to the UK’s energy future.
- Confirming short lifetime extensions for all four AGR (advanced gas-cooled reactor) stations, that will generate up to 45 TWh of additional power over the extended lifetimes, cutting UK emissions and reducing reliance on imported gas.
- Recruiting 2,000 people in communities across Britain in 2024 and aiming to recruit more than 3,000 roles in 2025, including more than 600 apprentices and graduates. Diversity in senior leadership also rose to 36%.
- The Customers business was named one of The Sunday Times Best Places to Work 2025, ranking in the top 10 in our category. It also achieved a 5-star rating on Trustpilot, with an impressive 4.8 score, reflecting its commitment to customer satisfaction and service excellence.
- 383,000 households were supported in 2024, clearing £1.5 million in customer debt, and nine out ten of those supported remained debt free for at least 12 months.
- Offered customers free electricity through it’s ‘Sunday Saver’ challenge, with 88% of ‘Sunday Saver’ participants earning at least four free hours, with over £2.73 million credited to customer bills since the scheme began.

[i] EDF produced 17% of the UK’s total electricity generation in 2024: https://www.edfenergy.com/zero-carbon
UK Fuel Mix disclosure information, published by Government Department for Energy Security and Net Zero, recognises electricity from wind, solar and nuclear fuel produces zero carbon dioxide emissions at the point of generation.
The zero-carbon electricity purchased is supplied to the National Grid. Customers receive electricity via the National Grid, not directly from zero-carbon generators.
The table below summarises zero-carbon generation by company, demonstrating EDF generating 17%. The data supporting the table below and the % values are sourced from a mixture of industry settlement data and the UK government renewable obligation database.
| Company | Nuclear / onshore wind / offshore wind / solar / biomass / hydro TWh 2024 | % of total UK zero carbon electricity generated 2024 |
| EDF | 31.4 | 17.0% |
| Drax | 15.4 | 8.3% |
| RWE | 11.1 | 6.0% |
| Orsted | 10.5 | 5.7% |

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, one of the UK and Ireland’s largest technical service providers.
