## Summary

Network Rail Infrastructure Limited, based in London, is advancing its long-term decarbonisation and sustainability objectives through the Phase 2 - Filton Renewables - Prototype R&D Project. This contract has been awarded via direct award to Turbo Power Systems Ltd, a company known for its expertise in advanced power electronic systems. The contract, which follows the completion of Phase 1, now enters the award stage with the contract signed on 17 October 2025 and runs from 20 October 2025 to 19 October 2027, with the option for renewal to 2028. The project's scope is the development of a 25 kV Integrated Converter Prototype for railway use, with direct procurement justified under the Procurement Act 2023 due to the unique technical capabilities required. The main procurement category for this contract is services, classified under Experimental development services.

This direct award provides a unique opportunity for Turbo Power Systems Ltd to further establish itself in the rail industry's R&D sector, showcasing their ability to handle complex and innovative projects. Given the project's focus on renewable energy and technical exclusivity, businesses with capabilities in high-tech engineering, especially those specialising in electronic systems and sustainable innovations, would find potential growth in similar procurement opportunities. The collaboration with Network Rail could lead to visibility and credibility enhancements, opening doors to future partnerships and projects within the infrastructure sector.

## Notice

Network Rail (Wales and Western) intends to award a contract via direct award under the Procurement Act 2023 to Turbo Power Systems Limited (TPS) for the continued development (Phase 2) of a first-of-its-kind 25 kV Integrated Converter Prototype for use on the railway. This prototype forms part of a strategic innovation programme to enable the use of self-generated renewable energy for powering electric trains -- a key enabler of Network Rail's long-term decarbonisation and sustainability objectives. TPS, a specialist in advanced power electronic systems, initially proposed the concept to Network Rail and successfully delivered Phase 1, which included the design and demonstration of a proof of concept. This was formally reviewed and approved by Network Rail's Technical Authority, confirming both technical feasibility and alignment with operational requirements. The Phase 2 contract will progress the innovation to a functional prototype, building directly on the technical foundations established in the initial phase.

### Procurement Information

A direct award is justified under Section 41(1)(b) of the Procurement Act 2023 due to the absence of competition for technical reasons. TPS retains all intellectual property rights (IPR) over the existing design and remains the only economic operator with the capability to deliver the required next stage of development.
