Description

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.
