Britain to invest a further 14.2 billion pounds in Sizewell C nuclear project

The government has committed another £14.2 billion to the Sizewell C nuclear plant, bringing the total public investment in the project to a significant level. 

Sizewell C secured new funding from recent spending review decisions, benefiting from its shared EPR reactor design with Hinkley Point C to potentially avoid past construction issues. With most planning hurdles cleared, the Suffolk site is well ahead of other proposed nuclear developments.

Nuclear capacity is becoming critical as older plants shut down. Most of the current atomic fleet will close by 2035, removing about 6GW of reliable generation from the system. Wind and solar cannot provide that kind of round-the-clock power output.

The plant will generate enough electricity for 6 million households once both reactors are running. That's roughly equivalent to powering Greater London's residential demand.

Construction will create around 10,000 jobs, with over 2,000 UK suppliers expected to contribute components and services. The nuclear supply chain has been rebuilding after years of limited activity, so this project helps maintain those capabilities.

Private investors still need to sign on before construction can begin properly. The government money covers development costs and initial work, but the full £40 billion project cost requires additional financing partners.

Nuclear projects globally have struggled with cost overruns and delays. Hinkley Point C is running years late and billions over budget. Sizewell C benefits from lessons learned there, but large infrastructure projects always carry execution risks.

The investment supports a comprehensive energy policy featuring both nuclear baseload capacity and expanded renewable energy sources. Gas plants will likely fill any remaining gaps, but nuclear provides the consistent output needed when wind and solar are not producing.
