Government adopts novel finance structure for Sizewell C and will need to monitor risks closely

We have just published our new report, which examines the deal the Department for Energy Security and Net Zero has reached with private investors to construct the Sizewell C nuclear power plant.


DESNZ estimates Sizewell C net benefits of up to £18 billion over the site’s operational life. But, to help fund construction, electricity bills for the typical household could rise up to £19 a year by the time it opens from 2039.  


The novel delivery model for Sizewell C places more risks on taxpayers and consumers than other electricity projects, but the Department believes this model has reduced finance costs and will allow the project to be delivered on time and to budget.
