## Summary

The public procurement process was led by High Speed Two (HS2) Ltd for the "High Voltage (HV) Power System for the HS2 Project." This procurement falls under the works category (CPV 45230000) and is located in the United Kingdom. The procurement stage is at the award stage, with the contract having been signed on 20th January 2025. The project involves the design, build, testing, commissioning, and maintenance of HV power systems for the HS2 railway project. Siemens Mobility Costain JV was awarded the contract to execute these tasks. Key elements include interfacing with the Distribution Network Operators, National Grid, and procuring necessary consents, with an initial maintenance contract term of 7 years and options to extend. The procurement method used was a selective negotiated procedure with prior call for competition.

This tender provides significant growth opportunities for businesses involved in high voltage power systems, railway systems engineering, and maintenance services. Companies with expertise in electrical installation work, particularly those with experience in transformers, power supply transformers, switchgear, and SCADA systems, would find this project well-aligned with their capabilities. Additionally, businesses that can offer reliable long-term maintenance services for large-scale infrastructure projects are well-suited to compete. Given the scale and complexity of the HS2 project, larger firms or joint ventures with a robust track record in similar contracts will have a strategic advantage. This contract offers a long-term engagement with HS2, potentially leading to further opportunities within the expansive HS2 infrastructure framework.

## Notice

This contract relates to a single package of work for Design and build of High Voltage (HV) Power Systems for the HS2 Project plus a separate contract for ongoing maintenance. The scope of work includes the design, build, testing & commissioning, training, and provision of all required hand-over documentation & spares. The scope also includes interfacing with Distribution Network Operators (DNO), National Grid, and procuring of consents. The scope of work for maintenance includes the ongoing maintenance of the completed works.

### Lot Information

Lot 1

The High Voltage (HV) Power Systems package of work comprises: * design, build, testing and commissioning of the High Voltage (HV) traction power systems, 33kV and 11kV non-traction power systems and HV SCADA (Supervisory Control and Data Acquisition) for the HS2 Project. * ongoing maintenance activities in connection with the High Voltage (HV) Power Systems. The HV Traction Power Systems include a traction power electrification system which will be a -25-0-25kV Autotransformer system with a nominal fault current level of 15 kA. The system will be designed to supply traction power into the Overhead Catenary System (OCS) - provided by others to enable the railway operator to run its specified train timetable. The non-traction power systems will supply all necessary railway systems facilities in tunnels and open route at the appropriate, power demand and system availability. The non-traction power systems will be a dedicated private network distributed within the tunnels and open route supplied by connections to the DNO (provided by the Employer). The 33kV and 11kV is to be transformed down at specified locations by the contractor to enable the onward supply of LV power (provided by others) to stations, shafts, portals, tunnels and rail systems. The High Voltage (HV) Power Systems Contractor is the Principal Contractor (PC) for the railway systems compounds. The High Voltage (HV) Power Systems Contractor will supply traction and non-traction power to the HS2 rolling-stock maintenance depot at Washwood Heath (Birmingham), this will include interfacing with the Network Integrated Control Centre (NICC). The HV Power Systems Contractor is required to provide temporary supplies for construction use at its Railway Systems Compounds (RSC) where it is principal contractor, this may involve adopting the temporary supplies previously provided by MWCC. This notice also relates to a maintenance contract, pursuant to which the contractor shall provide maintenance services in relation to the completed works. The maintenance contract will be valid for an initial term of 7 years with options to extend and will commence on the first sectional completion of the works under the design and build contract.
