WSP in support of planning application for EDF Energy’s Sizewell C

 WSP has provided transport planning advice for Sizewell C since 2012 which has now been submitted to Planning Inspectorate for Development Consent Order.

EDF Energy’s Sizewell C nuclear power station has an important role to play in the UK’s transition to a net zero economy, the engineering professional services consultancy WSP has said today

EDF submitted an application for a Development Consent Order (DCO) on Wednesday 27 May to the Planning Inspectorate who are now considering the application’s suitability for acceptance. The Sizewell C application documents will be publicly available after this 28-day acceptance period.

The nuclear power station in Suffolk would generate around 7% of the UK’s electricity demand, which equates to around six million homes, and provide low carbon power for 60 years.

It will also save nine million tonnes of carbon dioxide emissions in each year of its operation and help provide the essential baseload capacity needed to replace coal and gas – a vital component of the UK’s transition to a net zero economy by 2050.

WSP has worked with EDF and stakeholders to develop the wider transport strategy for the project. Since 2012, WSP has provided transport assessment and traffic modelling expertise and prepared the preliminary engineering designs for the associated transport infrastructure around Sizewell C. WSP also provided transport planning support throughout all four stages of consultation.

Throughout the project, WSP has undertaken extensive liaison with Suffolk County Council, Highways England, Network Rail and other stakeholders.

WSP is currently involved in 12 development consent order applications across the UK, including the A303 Stonehenge road tunnel in Wiltshire, and recently saw its design for the Lake Lothing Third Crossing in Lowestoft receive approval from the Department for Transport.

Ian Liddell, Managing Director for Planning & Advisory at WSP, said: “The significance of Sizewell C to both the UK’s 2050 net zero target and the regional economy in Suffolk cannot be understated. It’s a truly exciting project which will enable six million homes to receive electricity through low carbon generation – around 7% of our entire electricity demand – and support jobs and growth in the local area. WSP is proud to be supporting our client EDF on this journey.”

In May, WSP and thinktank Bright Blue launched Delivering Net Zero: Building Britain’s Resilient Recovery, a collaborative manifesto on how the UK can deliver a net zero economy and society by 2050. It includes a contribution from Paul Spence, Director of Strategy and Corporate Affairs at EDF, on the role of nuclear power in the UK transition to net zero.
