## Summary

The public procurement process for the "HS2 Limited High Voltage (HV) Power System" project, led by HS2 Ltd., focuses on the design, build, testing, and commissioning of HV power systems required for the HS2 Project. This project is in the award stage, with Siemens Mobility Costain JV being the contracted supplier. Worth approximately £328.2 million, the contract runs from 3rd February 2025 to 26th August 2049. The project falls under the industry category of construction and electrical installations, specifically transformers and HV installation work, covering multiple regions including the United Kingdom, British Overseas Territories, and Europe. The procurement method used was a competitive procedure with negotiation, and the tender period concluded on 21st November 2023.

This tender presents significant opportunities for businesses involved in electrical installations and railway construction. Firms specialising in HV power systems, SCADA systems, and engineering design services would find this project particularly aligned with their expertise. Given the scope of work, including design, ongoing maintenance, and system integration, the project is well-suited for large-scale enterprises with the capacity to handle complex infrastructure projects. The substantial contract value and long-term maintenance aspect offer the potential for sustained business growth and partnership opportunities in the highly strategic rail sector.

## Notice

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.
