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. ## Notice UKAEA are looking to engage a Supervisory Control And Data Acquisition (SCADA) specialist to develop a new SCADA system in J5 based on the IEC 61850 protocol, replacing the existing SCADA. The work includes the design, manufacture, delivery, installation, and commissioning of the complete system, including an operator workstation in J5 control room. The SCADA will provide full control authority in J5 and D8, with intelligent interlocking to prevent failures or operational errors. The system will integrate with all numerical and auxiliary devices, transmitting all alarms, trip signals, and status indications over fibre or Ethernet to the main control room. A GPS-synchronized clock will ensure accurate system timing. Additionally, a rugged firewall will be implemented to protect the system against cyber threats, ensuring secure and reliable operation. ### Planning Information https://uk.eu-supply.com/app/rfq/rwlentrance_s.asp?PID=99581&B= ## Key Details | Field | Value | | --- | --- | | Publication source | Find A Tender Service | | Latest notice | https://www.find-tender.service.gov.uk/Notice/014500-2026 | | Notice type | UK12 - Procurement Termination Notice | | Procurement type | Standard | | Procurement category | Goods | | Procurement method | Open | | Procurement method details | Open procedure | | Tender suitability | SME | | Awardee scale | Not specified | | All stages | Planning, Tender | ## Dates | Field | Value | | --- | --- | | Publication date | 17 Feb 2026 | | Submission deadline | 23 Feb 2026 | | Future notice date | 1 Dec 2025 | | Award date | Not specified | | Contract period | 1 Apr 2026 - 31 Mar 2032 | | Recurrence | Not specified | ## Values | Field | Value | | --- | --- | | Tender value | £400,000 | | Lots value | £400,000 | | Awards value | Not specified | | Contracts value | Not specified | ## Status | Field | Value | | --- | --- | | Tender status | Cancelled | | Lots status | Cancelled | | Awards status | Cancelled | | Contracts status | Not specified | ## Buyer | Field | Value | | --- | --- | | Main buyer | UK ATOMIC ENERGY AUTHORITY | | Additional buyers | Missing | | Locality | OXFORDSHIRE | | Post town | Oxford | | Postcode | OX14 3DB | | Country | England | | ITL 1 | TLJ South East (England) | | ITL 2 | TLJ1 Berkshire, Buckinghamshire and Oxfordshire | | ITL 3 | TLJ14 Oxfordshire CC | | Local authority | South Oxfordshire | | Electoral ward | Sandford & the Wittenhams | | Westminster constituency | Didcot and Wantage | | Delivery location | TLJ14 Oxfordshire CC | ## CPV Codes ### Divisions - 42 - Industrial machinery ### Codes - 42961200 - Scada or equivalent system ## Release History - 17 Feb 2026 at 16:30 - TenderCancellation - UK12 - Procurement Termination Notice - https://www.find-tender.service.gov.uk/Notice/014500-2026 - 26 Jan 2026 at 17:00 - Tender - UK4 - Tender Notice - https://www.find-tender.service.gov.uk/Notice/006835-2026 - 31 Oct 2025 at 15:09 - Planning - UK2 - Preliminary Market Engagement Notice - https://www.find-tender.service.gov.uk/Notice/070161-2025 ## Documents - https://www.find-tender.service.gov.uk/Notice/014500-2026 17th February 2026 - Procurement termination notice on Find a Tender - https://www.find-tender.service.gov.uk/Notice/006835-2026 26th January 2026 - Tender notice on Find a Tender - https://www.find-tender.service.gov.uk/Notice/070161-2025 31st October 2025 - Preliminary market engagement notice on Find a Tender ## Notice URLs - https://uk.eu-supply.com/app/rfq/rwlentrance_s.asp?PID=102101&TID100107323&B= - https://uk.eu-supply.com/app/rfq/rwlentrance_s.asp?PID=99581&B= - https://www.gov.uk/government/organisations/uk-atomic-energy-authority - https://www.legislation.gov.uk/ukpga/2023/54/contents ## Provenance This Markdown file is an alternate public rendering of the D3 Tenders contract record.
