Sizewell C's business is to design, finance, construct, commission, operate, maintain, and eventually decommission the nuclear power plant and related infrastructure at Sizewell C in Suffolk. Overall, whilst the Company is in the construction phase, the Boards' principal focus is on the development and construction of Sizewell C on time, on budget and to the highest quality and safety standards. The Company is maturing to meet all these requirements.
Sizewell C is economically regulated by OFGEM under the Regulated Asset Base (RAB) model similar to other UK electricity distribution networks and Thames Tideway.
Sizewell C construction strategy is to replicate the design of Hinkley Point C, using the majority of the same supply chain, but innovating in the way it is delivered to achieve savings in time and cost of around 20%. The CCO will need to be guided by and incorporate lessons learned from the Hinkley Point C commercial delivery to achieve Sizewell C's ambition.
Following Financial Completion and Revenue Commencement, Sizewell C is fully funded and is owned by; The Secretary of State for Energy Security and Net Zero representing HM Government, La Caisse, Centrica, EDF and Amber Infrastructure.
Sizewell C is entering an exciting phase of growth as we mature into an independent organisation and continue building one of the UK's largest and most important energy projects. We are now recruiting the below position.
