Financial Close achieved for 3.2 GW Nuclear Power Plant in UK

Sizewell C has reached financial close, securing GBP5 billion (US$6.5 billion) in export credit-backed debt and a GBP500 million (US$653 million) working capital facility following its final investment decision in July 2025. The financing, supported by international export credit agencies such as BpifranceAE, has earned investment-grade credit ratings, reflecting strong investor confidence in the project’s structure and long-term viability.

Classified as a green loan under Sizewell C’s Green Financing Framework, the funding underscores the project’s contribution to the UK’s net-zero ambitions. The nuclear plant will supply low-carbon electricity to six million homes for at least 60 years, playing a crucial role in enhancing the country’s energy security.

The project is also expected to deliver significant economic benefits, including 10,000 new jobs, 1,500 apprenticeships, and over 70% of construction spending directed toward UK businesses. With financial backing now in place, Sizewell C moves forward as a key milestone in advancing the UK’s clean and sustainable energy future. Legal and financial advisors, including Clifford Chance, Rothschild & Co, BNP Paribas, and HSBC, supported the transaction.
