Good progress made at Shurton 400 kV substation

June 3, 2020

Two new nuclear reactors are being built at Shurton, Hinkley Point C, 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. The Linxon operations at Shurton started in July 2019 and is now well underway and on schedule for the connection date of April 2022.

As part of National Grid’s Hinkley Connection Project, Linxon will design, manufacture and install the Shurton 400-kV GIS indoor substation, which will provide double circuit connections to existing substations at Taunton and Melksham. Gas-insulated busbars will connect switchgear to overhead line and cable circuits.

The new substation will rely on a new 400-kilovolt (kV) GIS (gas-insulated switchgear) substation from Linxon (an ABB and SNC-Lavalin company) to transfer power from the plant to the UK’s transmission network, which includes substation construction and the integration of six 700-megavolt ampere (MVA) generator transformers, six auxiliary transformers, 400-kilovolt (kV) GIS, control, MicroSCADA systems and transmission feeds.

The site works also involves heavy civils, substation construction and all the necessary ground works.

The project is a significant milestone in the revitalisation of the UK’s nuclear power industry and it 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.







Since the first spade in August 2019, Linxon has been making good progress at site works in Shurton.
