HS2 has announced its shortlist of bidders for its high voltage (HV) power supply systems. The winner of the contract – worth an estimated £523 million – will be responsible for the design, manufacture, supply, installation, testing, commissioning and maintenance of the HV power supply systems, both traction and non-traction.
The competition was launched in August 2020 and has now entered its second stage with the announcement of the shortlisted suppliers, which will be invited to tender:
- Colas / Eiffage Joint Venture
- Siemens / Costain Joint Venture
- SSE Enterprise Contracting / Linxon / Arcadis Joint Venture
- UK Power Networks Services (Contracting)
The HV power systems contract will be a single stage procurement, with the successful bidder delivering two separate contracts covering design & build and maintenance services within Phase One and Phase 2a – from London to Crewe, where HS2 services will join the existing west coast main line.
Approximately 50 traction sub-stations will be built alongside the line between London and Crewe in order to deliver power from the National Grid to the trains. The contractor will also deliver a dedicated HV non-traction power network that will provide power to stations, shafts, portals, depots and railway systems along the route.
The successful tenderer will be responsible for design and will be expected to work closely with HS2’s other rail systems suppliers to ensure integration of its design and throughout construction, testing and commissioning.
HS2 procurement and commercial director David Poole said: “The shortlist for high voltage power supply systems is another major milestone, as we put in place the key rail systems teams that will take over once the civil engineering stage is finished.
“Once complete, HS2 will be one of the lowest carbon ways to travel, freeing up more capacity on the existing rail network and helping to take cars and lorries off the roads.
“Our power supply systems are a crucial part of the project and part of a solution which will help the UK reach net zero by 2050.”
