Crossrail shortlists three for £25m power system

Crossrail has announced the three bids shortlisted for the design, installation and commissioning of Crossrail’s central section traction power system.

Balfour Beatty Engineering Services, AC Joint Venture (Alstom Transport and Costain) and Rail Power Joint Venture (Siemens PLC and J Murphy & Sons) have been shortlisted for the contract worth around £25m.

The works will involve the construction of feeder station sites at Pudding Mill Lane and Kensal Green where power from the 400 kV National Grid network  will be converted down to 25 kV before being fed into the overhead line equipment that will power the new Crossrail trains.

Four high-voltage auto transformer stations will be constructed at Westbourne Park, Stepney Green, Custom House and Plumstead to maintain the voltage along the line.

The contract is one of the first power contracts to proceed through the Crossrail procurement process. Separate contracts will be let for high-voltage supply and tunnel fit-out which includes the installation of power equipment in the tunnels.

The contract is due to be awarded in spring 2013.
