Leiston-cum-Sizewell

Main Development Site

• Activity: Site construction
• Start Date: 4th September 2023
• End Date: 31st December 2034

This area is the Main Development Site for Sizewell C.

Work on the Temporary Construction Area continues with the completion of acoustic fencing to mitigate impacts on local wildlife. Preparation for the construction of the desalination plant is progressing as well as the construction of the northern haul road which is required to move materials around our site during the main civil works on the Main Construction Area. This route requires the bridge over the Site of Special Scientific Interest to be constructed which is well under way. Works to the northern side of the bridge include finishing the installation of the sheet piles which act as an environmental barrier, and on the southern side of the bridge works are underway to begin installing the sheet piles.

Works on the Main Construction Area also include preparing compounds for installation of the desalination plant water shaft.

Construction of the northern section of the temporary sea defence has started with the first sheet piles being installed. The works will take place within the Sizewell C fence line and the public footpath will remain open. We apologise for any noise disturbance which we will endeavour to keep to a minimum.

Works will soon commence on installing a temporary outfall on the beach. This work will be a short duration and within a fenced compound
