UK Watchdog Labels Sizewell C Nuclear Plant a Terrible Deal

The Public Accounts Committee warns that the Sizewell C nuclear project poses extraordinary financial risks to UK taxpayers while favoring private investors.

The Public Accounts Committee has branded the funding plan for the Sizewell C nuclear power plant in Suffolk a terrible deal for UK taxpayers. The watchdog warned that construction costs could reach £47.7bn, potentially leaving consumers and taxpayers to cover an additional £9.8bn during construction and £12bn over the plant's 60-year lifespan, while private investors' additional contributions would be limited to £30m.

The Government of the United Kingdom currently holds a 44.9% stake in the project after buying out the Chinese state developer CGN due to national security concerns. Other investors include EDF, Centrica, La Caisse, and Amber Infrastructure. The Public Accounts Committee has demanded more frequent progress updates and the scenario analysis used for cost estimates to address these financial risks.

Sizewell C CEO Nigel Cann and the Department for Energy Security and Net Zero defend the project, arguing that using the Hinkley Point C design will reduce risks and enhance energy independence. However, critics from the Stop Sizewell C campaign and Greenwich Business School argue that abandoning the project now would be more cost-effective than paying inflated energy bills for decades.
