The Planning Inspectorate is due to make a decision this week on EDF's application for Sizewell C.

Updated: Jun 20, 2020

The Planning Inspectorate has until Wednesday 24th June 2020 to decide whether or not to accept EDF's application for their proposal to build a new nuclear power station, which would comprise of two European Pressurised Reactors (EPR's) at Sizewell in Suffolk. The plant known as Sizewell C, would be located just North of the existing Sizewell B power station and would generate around 3,260 megawatts (MW) of electricity.

Sizewell C would be nearly identical in design to the Hinkley Point C power station under construction in Somerset and the timing could provide continuity for staff who have now trained in Somerset. This would enable them to transfer the important lessons learnt, onto the Sizewell C development. In addition, if approved the much needed economic boost couldn't have come at a better time, following the Covid-19 pandemic.

If the Development Consent Order (DCO) is granted, financing would still need to be arranged for the estimated £16-20bn construction cost, but if successful the plant could generate sufficient electricity to power six million homes, whilst also providing additional resilience in the UK's production capacity, which in turn reduces the needs for costly imports.

The construction of Sizewell C would generate 25,000 construction jobs and 1,000 apprenticeships, followed by 900 skilled jobs upon completion.
