Opportunity overview

This opportunity is published to advertise a preliminary market engagement exercise being conducted by National Gas Transmission PLC ("NGT"). NGT is seeking feedback from the market to support and refine its approach to a forthcoming procurement process in respect of the RIIO-GT3 Control System Replacement Main Works Contractor (MWC) Framework. Who are NGT NGT play a vital role in delivering gas to millions of people across Great Britain. NGT owns, manages, and operates the National Transmission System ("NTS") in Great Britain, making gas available when and where it's needed. NGT ensure that the network is safe, reliable and available, and that it delivers value for our customers and stakeholders, while minimising impact on the environment. What is the Control System Replacement Programme The overarching scope of each project in the programme is the complete replacement and upgrading of the compressor station's control systems to enhance cyber resilience. This involves modernising legacy infrastructure, implementing robust cybersecurity measures, and ensuring that the control systems are capable of withstanding evolving digital threats. The upgrades are intended to safeguard operational integrity, protect critical assets, and align with national and international standards for cyber-secure infrastructure. RIIO-GT3 Control System Replacement MWC Framework NGT has now transitioned from the RIIO-GT2 regulatory period into RIIO-GT3, which runs from April 2026 to March 2031. As part of this new regulatory period, NGT is implementing a new delivery model for the remaining projects within the Control System Replacement Programme. Under this model, a FEED Partner will be appointed to undertake the FEED study for each project. Upon completion of the FEED phase, NGT will appoint a Main Works Contractor (MWC) to deliver the detailed design, manufacture, installation, testing, and commissioning of the relevant station control system works. To support the efficient delivery of the programme, NGT intends to establish a framework agreement through which a number of Main Works Contractors will be appointed and subsequently engaged to deliver projects across the programme.
