Hinkley Point C supply chain backed for Sizewell project

3095457 sizewell cgi

Reusing the exiting Hinkley Point C supply chain could shave 20% off of the cost of Sizewell C, according to a boss at EDF.  

Speaking at the Nuclear Industry Association conference in London, EDF non-executive chairman Colin Matthews said that it was important to keep the supply chain currently supporting Hinkley Point C active and ready to take on work for the new plant at Sizewell C.  

“A few decades ago after the last nuclear new build, the supply chain was starved of work,” he said.  

“What if this time, we do it differently? Having built Hinkley Point C, we were to reuse and develop our supply chain further and take on new work?”  

In total, 64% of the project value for Hinkley has been procured in the UK, that represents £10.6bn injected into the UK economy, and the south-west around Hinkley. 

Matthews called on the sector to make sure that as much of this investment is reused as possible, including technology and policy, to drive down costs for Sizewell as much as 20%.  

“What if we were to take all of the engineering works and technologies and transfer the experience from Hinkley Point into the new construction [of Sizewell C],” Matthews said. “We [EDF] think if we do all this we can cut costs of construction by a significant 20%.” 

“Hinkley needs to be a repeated success, not a one off,” Matthews added.  

In January, EDF Energy claimed it could deliver the new nuclear power station Sizewell C for around £5bn less than Hinkley Point C by “copying and pasting” to slash pre-construction costs. 

Sizewell C would be located north of its sister plant Sizewell B on the Suffolk coast. EDF estimates the 3.2GW power plant will take 10 to 12 years to build.
