UK2 - Preliminary Market Engagement Notice
Summary of the contracting process

The UK Atomic Energy Authority is seeking a specialist for the 33kV Substation SCADA Supply project, involving the design, manufacture, delivery, installation, and commissioning of a SCADA system based on the IEC 61850 protocol. The location is at the Culham Science Centre in Oxfordshire, UK. The procurement process is currently at the tender stage, with a tender period ending on 23rd February 2026 and an award period concluding on 13th March 2026. This open procedure is governed by legal provisions under UKPGA 2023/54. The procurement falls within the goods category, specifically targeting SCADA or equivalent systems, with an estimated gross value of £480,000. The contract period is set from April 2026 to March 2032, offering medium to long-term engagement potential for suppliers.

This tender represents a promising opportunity for businesses specialising in SCADA systems and cybersecurity solutions, with a particular interest in suppliers that can provide secure and reliable operations through rugged firewalls and intelligent interlocking. The UK Atomic Energy Authority's emphasis on Cyber Essentials suggests that firms with strong cybersecurity credentials may have a competitive advantage. Given its suitability criteria favouring SMEs, smaller enterprises with specialised expertise in SCADA systems could find significant growth opportunities by aligning their offerings with project requirements. Business growth can be achieved by leveraging robust technical capabilities and competitive pricing to meet the quality and price evaluation criteria equally weighted in the procurement process.
