The hardware that makes it all possible

Delivering major infrastructure projects safely and efficiently is central to Capital Delivery. It’s about ensuring that our electricity transmission network is able to connect the energy generated by power stations, wind and solar farms to where it’s needed, while our gas transmission network is working effectively. 

What we do

We bring together all of the major digging, tunnelling, excavating, overhead line and cabling work for our large gas and electricity transmission projects. It’s incredibly diverse and challenging construction work – from the creation of new 400kV circuits at the heart of London’s electricity network to the installation of state-of-the-art security to protect our operationally critical sites.

Our projects

    London Power Tunnels

    In February 2011, National Grid embarked upon a seven-year project to rewire the capital via deep underground tunnels, in order to meet increasing electricity demand. The project will create a new 32km electricity superhighway deep below the capital, which will help keep Londoners connected to safe and reliable electricity supplies and also provide new grid supply points for Crossrail and UK Power Networks. The project is due to be complete and fully operational in 2018.

    Western Link

    Western Link is a £1 billion project which will help to bring renewable energy from Scotland to homes and businesses in Wales and England. It is a joint venture between National Grid and Scottish Power Transmission and it comprises a converter station at Hunterston, North Ayrshire; 4km of high voltage direct current cable to a ‘landfall’, where the subsea cable comes ashore, at Ardneil Bay; a subsea marine cable approximately 385km long from Ardneil Bay to Leasowe on the Wirral peninsula; an underground high voltage cable around 33km through the Wirral peninsula; and a converter station in Deeside, Flintshire.

    Flintshire Bridge is the converter station in Deeside, Flintshire on the Southern side of the Western Link project. The Western Link project will bring renewable energy from Scotland to Wales and England. This site was built from scrubland to the fully completed converter station in three years.
