Overview

• The UK government formally approved its final investment decision on July 22, securing a £38 billion funding package for Sizewell C.
• Under the agreement the government will hold a 44.9% stake alongside CDPQ (20%), Centrica (15%), Amber Infrastructure (7.6%) and EDF (12.5%).
• Sizewell C will feature two next-generation EPR reactors designed to generate low-carbon power for six million homes with first output slated for 2035.
• This marks the first occasion the UK government has taken an ownership share in a nuclear power station, signalling a strategic shift in its role in energy infrastructure.
• While total costs rose from initial £20–30 billion estimates to £38 billion, per-reactor expenses are expected to be about 20% lower than at Hinkley Point C due to scale efficiencies.
