Hinkley Point C Connection Project

Hinkley Point C Connection Project – an £8 Million 400kV Substation Build for the National Grid

Two new nuclear reactors are being built by EDF at Hinkley Point C in Somerset, which is the first in a new generation of nuclear power stations in the UK, that will provide low-carbon electricity for around six million homes. This is a significant milestone in the revitalisation of the UK’s nuclear power industry. Hinkley Point C will make a major contribution to the UK’s move to reduce carbon emissions. The electricity generated by its two reactors will offset 9 million tonnes of carbon dioxide emissions over its 60-year lifespan.

The Hinkley Point C Project is currently the biggest construction project in Europe

H&Askham are involved in a 400kv substation build at Shurton near the main Hinkley site, working with Linxon, a major tier 1 supplier to the National Grid. H&Askham’s involvement in the substation project began as a small scope of work, starting in March 2019 and finishing a few months later in June 2019, with a relatively small project value of £100,000.

 

This small project got big and gave us the opportunity to demonstrate our project and performance capabilities in front of some major players in the construction and nuclear power sectors. The successful delivery of the initial work scope by our highly skilled project team, led to a further significant contract win, worth over £8 million.  The project started in July 2019 and is now well underway and will be completed early 2021.

The onsite H&Askham team is working with Linxon, to connect power from Hinkley Point C power station, to the National Grid, through a 400kV substation.

This involves heavy civils, substation construction, and all the necessary groundwork. The teams are building a GIS hall and annex to house the substation gas-insulated switchgear. Large reinforced concrete structures are being constructed, with 9-meter-high in-situ walls, to house the series reactor. We are also responsible for all on-site infrastructure, including roads, car parks, ISS high-security fencing, GIB and AIS structures, as well as installation of steelwork and gantry structures.

The Shurton project win has created valuable new jobs – we have grown from a small team of 10 undertaking the initial scope to have a workforce in the region of 60 operatives, technicians and engineers on-site for some elements of the build. Not only is the project our biggest win to date, but it has given our team the opportunity to demonstrate our engineering prowess, in dealing with the technical challenges we have faced and overcome.

Winning this major flagship project at Shurton and working alongside Linxon – a major Tier 1 supplier to the National Grid, has accelerated our profile within this industry considerably. H&Askham Group has a very bright future in providing high voltage solutions, within the nuclear power sector.
