EDF to Invest $1.5 Billion in UK's Sizewell C Nuclear Project

EDF, a French nuclear energy utility, will invest $1.5 billion in the Sizewell C nuclear project in Britain. The British government has committed £17.8 billion to the project, but continues to seek additional investors. EDF's stake in the project will increase to 12.5%, and the company has previously invested €652 million. The Sizewell C plant is projected to generate enough electricity to power around 6 million homes.

French nuclear energy utility EDF will invest around $1.5 billion in the Sizewell C nuclear project in Britain, according to an announcement made during French President Emmanuel Macron's state visit to Britain [1]. This investment, which will increase EDF's stake in the project to 12.5%, is part of Britain's broader strategy to bolster energy security and meet its climate target of net zero emissions by 2050.

The Sizewell C plant, currently under construction, is projected to generate enough electricity to power around 6 million homes [2]. It is set to be the second new nuclear plant built in Britain in more than two decades, following EDF's Hinkley Point C project. While the government has not specified the total cost of the Sizewell C project, EDF has indicated that it will be around 20% cheaper than Hinkley Point C [2].

The British government has already committed £17.8 billion to the project but continues to seek additional investors. US-listed investment fund Brookfield has agreed to take a stake of more than 20% in the project in exchange for funds to finance the development of the nuclear plant [1]. British utility Centrica has also expressed interest in the project but has yet to make a formal announcement [1].

The project's Final Investment Decision (FID) is expected by July 21, 2025, which will be a critical juncture for the project's viability [3]. The UK government remains a significant shareholder in the project, ensuring oversight and limiting potential delays [1].
