Crossrail has shortlisted five companies for a non-traction high-voltage power supply contract, which will be tendered out later in 2012.
The selected company will be responsible for providing electrical power, distributed at 22kV or 11kV, within the tunnels and surface segments of the central section of Crossrail.
The five organisations that have been shortlisted include ABB, a Alstom Transport and Costain joint venture (AC JV), Balfour Beatty Engineering Services, a Siemens and J Murphy & Sons joint venture (Rail Power JV) and UK Power Networks (Commercial).
The C650 high-voltage power supply contract includes the design, supply, installation, testing and commissioning of the 22kV and 11kV non-traction power supplies to Crossrail tunnels.
The system will ensure a dedicated, reliable power supply to Crossrail stations, shafts and portals for all local and railway system loads except for train traction power supply.
Crossrail will operate a high-frequency metro service of up to 24 trains an hour during the peak between Whitechapel and Paddington.
The company said that construction of the new tunnels has begun, with the first tunnel boring machine (TBM) from Royal Oak towards Farringdon already on its way, while the second will be launched later this summer.
In March 2012, Crossrail shortlisted five companies for the £400m contract to design and provide track installation and equipment for London’s new Crossrail network tunnels.
Construction work on the 21km of twin-bore tunnel, stretching across the capital through central London and the Docklands, is expected to be completed in 2014.
