## Summary

The public procurement process involved Transport for Wales (TfW), which recently completed the award of a supply contract for "TfW - Substations with Contained Gas Insulated Switchgear." This procurement falls within the electrical equipment and apparatus industry category, specifically aimed at enhancing the South Wales Metro project. The contract was awarded following a limited procurement method due to the unique technical specifications required, with the supplier identified as Siemens Mobility Limited. The contract value is estimated at £4,500,000, and the award was finalised on 29 June 2020. The procurement was driven by a need to conform to various safety and design standards critical for railway infrastructure in South East Wales.

This tender presents significant opportunities for businesses engaged in the provision of electrical equipment, particularly those with expertise in switchgear and substation construction. Companies that can meet the stringent technical requirements outlined by TfW, especially those approved by the Network Rail Parts and Drawings System (PADS), would be well-positioned to compete in similar future procurement processes. With the ongoing development of the South Wales Metro, businesses involved in electrical installations, infrastructure development, and related services could leverage this project to expand their market presence and capabilities.

### Lot Information

Lot 1

TfW has awarded a supply contract to Siemens Mobility for the purchase of Side entry 8DA11 CGIS (Contained Gas Insulated Switchgear). Transport for Wales (TfW), and its delivery partners, are responsible for the development and delivery of the South Wales Metro, including the CVL Transformation programme, which will integrate public transport services and systems in South East Wales. Part of this programme includes the electrification of the Core Valley Lines in South East Wales (comprising Rhymey to Cardiff Queen Street, Coryton Spur, Merthyr Tydfil to Cardiff Queen Street, Aberdare to Cardiff Queen Street, Aberdare to Hirwaun, Treherbert to Cardiff Queen Street, Cardiff Queen Street to Cardiff Central and Cardiff Central to Cardiff Bay) and will require supply and fixing of substations to create the power network. TfW identified that Siemens Mobility is the only supplier capable of meeting TfW's requirements, for the following reasons. The required items must be supplied by a Network Rail Parts and Drawings System ("PADS") approved supplier of side entry 8DA11 CGIS (Contained Gas Insulated Switchgear) in order to conform to Network Rail and TfW standards, namely NR/L1/ELP/27000, NR standard NR/PS/ELP/27236 and PADS Certificate PA05/00637, including as well the following British Standards policies and legislations as detailed in NR/L1/ELP/27000: BS7671 - Requirements for electrical installations BS EN 50119 - Railway applications. Fixed installations. Electric traction overhead contact lines. BS EN 50122 - Railway applications. Fixed installations. Electrical safety, earthing and the return circuit BS EN 50149 - Railway applications. Fixed installations. Electric traction. Copper and copper alloy grooved contact wires BS EN 50163 & A1 - Railway Applications. Supply voltages of traction systems BS EN 50367 - Railway applications. Current collection systems. Technical criteria for the interaction between opantograph and overhead line (to achieve free access) BS EN 50388 - Railway Applications. Power supply and rolling stock. Technical criteria for the coordination between power supply (substation) and rolling stock BS EN 50463-4 - Railway Applications. Energy measurement on board trains.

The supplier must also have side entry cable capacity to ensure conformity with the standards detailed above and to meet the system design requirements where due consideration was given to all types of design and decisions based on concerns regarding land take and consents and potential for vandalism have led to the requirement for CGIS Switchgear. TfW's expert advisers conducted market investigations and on the basis of these Siemens is currently the only PADS approved supplier of CGIS switchgear with side entry which meets the above requirements.
