Croydon breakthrough

Morgan Est has broken through its 10km, £60M Croydon electricity tunnel for clients National Grid.

The tunnel broke through at the Beddington Substation site early on Tuesday morning, after almost two years work.

It is part of National Grid’s programme to reinforce electricity transmission in the South East and will house a new 400,000 Volt cable between linking substations at Beddington and Rowdown in south west London.

Morgan Est project manager George Jackson said: “This is a significant tunnel breakthrough for us and a major step forward in our work on this project. It has been technically a very challenging process and I am pleased to say the consistent dedication and hard work of the team has paid off.”

National Grid’s project manager Scott Sadler said: “The breakthrough represents another major step towards the completion of this vital project. It is the culmination of many months of hard work by our workforce. I would like to thank everyone for their efforts and would also like to thank local residents and businesses for bearing with us throughout the tunnelling process.

“We can begin preparing the tunnel for the installation of the new electricity cables which will link our substations at Beddington and Rowdown and help meet electricity demand in the capital city of London and nationwide.”

Additional works on the tunnel will include four shafts with surface buildings, two culverts and associated installation works. Cable installation will cost £20M.

The cable is due to go live in 2011.
