RIIO-GT3 Control System Replacement - Main Works Contractor Framework Opportunity

National Gas Transmission PLC (NGT) is conducting a market engagement exercise for a Main Works Contractor (MWC) Framework to deliver control system replacement projects across compressor stations during the RIIO-GT3 regulatory period (April 2026 to March 2031). NGT operates Great Britain's National Transmission System and is modernizing legacy compressor station control systems to enhance cyber resilience, implement robust cybersecurity measures, and align with national and international standards. The delivery model involves appointing a FEED Partner for initial studies, followed by Main Works Contractors selected from the framework to undertake detailed design, manufacture, installation, testing, and commissioning. Multiple contractors will be appointed to the framework and engaged across multiple projects throughout the programme. Interested parties should express interest by completing the response template, available upon request from Thomas.Jones@nationalgas.com or Syed.Kully@nationalgas.com. This is a preliminary market engagement exercise to gather feedback and refine NGT's procurement approach.
