Amey lands key HS2 power contract

Amey press release powering hs2 amey lands contract with key rail infrastructure project

Amey has won a key contract to design and construct the power supply for part of the new High Speed 2 (HS2) line.

As part of the contract Amey will design and construct two new temporary substations to support the delivery of the Chiltern Tunnel south portal.

The first substation will connect to the Scottish and Southern Electricity Network (SSEN) power grid to transform voltage levels from 132kV to 33kV. The second will then drop the voltage further from 33kV to 11kV ready for the distribution of power to the tunnelling equipment used to bore the Chiltern Tunnel.

Amey chief executive Andy Milner said: “The HS2 programme is an exciting piece of work for us and is testament to the skills and expertise of our long serving and dedicated workforce. The construction of the new substations will enable us to provide power to support the delivery of the Chiltern Tunnel for HS2.”

The Chilterns Tunnel is part of the £965M C1 package of civils works being built by Align JV which comprises of Bouygues, Volker Fitzpatrick and Sir Robert McAlpine. The joint venture is being supported by American consultant Jacobs and French consultant Ingerop.

Fugro is carrying out a £5.2M pre-construction site investigation for the tunnel.

The Chilterns Tunnel will be a 15.8km bored tunnel starting at Maple Cross and will have four vent shafts and one intervention shaft at Chalfont St Peter, Chalfont St Giles, Amersham, Little Missenden and Chesham Road.

In June this year it was revealed by New Civil Engineer that initial costs for High Speed 2 (HS2) main civil works are coming in around £1bn over budget.
