The engagement is currently in the planning stage and seeks to gather information from potential suppliers to refine its procurement strategy. Located at the Culham Science Centre in Oxfordshire, UKIFS is inviting written submissions from interested parties by 27th February 2026 and plans an online presentation and Q&A session during the week commencing 16th March 2026. This project falls under the engineering design services industry category and is part of a broader effort to enhance efficiency in power generation systems. This tender offers an opportunity for businesses specialising in engineering design, electrical power systems, and plant engineering design services to collaborate on an innovative project driving future energy solutions. Engaging in this PME can provide visibility and networking prospects for companies with expertise in high-performance condensers and CO2 power generation systems. Organisations that demonstrate capability in adhering to UK pressure equipment regulations and a strong understanding of the technical requirements associated with CO2 condenser operations will find this opportunity particularly suitable. The prospective procurement activity related to this project is expected to commence in April 2029, providing a long-term growth potential for participants in the evolving energy sector. ## Notice The following summary is not intended as a complete or definitive specification of the requirement. A purpose of this engagement notice is to seek information from the market to help refine our understanding and aid the development of a future specification. UKIFS is seeking experts to support the design and development of a CO2 condenser that is part of the STEP power cycle. This is because a high-performance CO2 condenser is critical to the efficiency of the STEP powerplant (supercritical and/or transcritical CO2 power generation cycles are currently the preferred concept for the STEP prototypic plant). The proposed technical and operating conditions of the proposed CO2 condenser are: *Operating pressure is between ca. 60-100 bar for the CO2 stream *Operating inlet temperature will be between ca. 50 - 110degC. The outlet temperature will be between ca. 20-25 degC for the CO2 stream. *Thermal duty is in the range of 1-2 GWth. *The equipment must comply with UK pressure equipment regulations. Please be aware, any future procurement activity associated with the CO2 condenser PME will likely occur in Tranche 2B of STEPs programme. T2B is due to start in April 2029 and is subject to formal sign-off of our design (T2A) and agreement of the whole T2B plan For more information about this opportunity, please visit the Delta eSourcing portal at: https://ukifs.delta-esourcing.com/tenders/UK-UK-Culham:-Engineering-design-services./7JNTY86XYK To respond to this opportunity, please click here: https://ukifs.delta-esourcing.com/respond/7JNTY86XYK ### Planning Information Scope of Preliminary Market Engagement Activities: This Preliminary Market Engagement (PME) exercise is intended to gather information from potential suppliers regarding the design and development of CO2 condensers. The engagement is currently expected to take place in two stages: The first stage involves a written submission via the questionnaire, which should be returned by 13:00 hrs on 27th February 2026. The second stage will be an online presentation (delivered by UKIFS) and Q&A session that multiple suppliers may attend. This is anticipated to be the week commencing 16th March 2026 (indicative only). For the avoidance of doubt: Suppliers who wish to attend the presentation and Q&A session will need to confirm that they wish to participate by indicating this within the questionnaire and submitting this via Delta as directed. Supplier's who do not to respond to this notice are NOT thereby excluded from any subsequent tender process for this workstream. As part of this PME, UKIFS may carry out a range of activities. These may include, but are not limited to: issuing follow-up questions to suppliers and reviewing their responses; engaging in discussions with suppliers either collectively or individually, such as through webinars or workshops; seeking feedback on proposed requirements; exploring procurement approaches; identifying potentially suitable suppliers; assessing market capacity; and discussing possible contractual terms. PME may also be used to support the development of award criteria and the refinement of tender documentation. Any information provided in this notice, such as CPV codes, estimated contract values, anticipated contract dates and durations, and proposed engagement timelines - are indicative only and based on UKIFS's current understanding. These details may be subject to change. The purpose of PME is to improve our understanding of the market, refine our requirements, and shape our procurement strategy. The list of activities included here is illustrative rather than exhaustive, and the nature, extent and timetable of engagement may evolve in line with UKIFS's needs. ## Key Details | Field | Value | | --- | --- | | Publication source | Find A Tender Service | | Latest notice | https://www.find-tender.service.gov.uk/Notice/004045-2026 | | Notice type | UK2 - Preliminary Market Engagement Notice | | Procurement type | Dynamic | | Procurement category | Services | | Procurement method | Not Specified | | Procurement method details | Not specified | | Tender suitability | Not specified | | Awardee scale | Not specified | | All stages | Planning | ## Dates | Field | Value | | --- | --- | | Publication date | 16 Jan 2026 | | Submission deadline | Not specified | | Future notice date | 27 Feb 2026 | | Award date | Not specified | | Contract period | 31 Mar 2029 - 30 Apr 2033 | | Recurrence | Not specified | ## Values | Field | Value | | --- | --- | | Tender value | Not specified | | Lots value | Not specified | | Awards value | Not specified | | Contracts value | Not specified | ## Status | Field | Value | | --- | --- | | Tender status | Planning | | Lots status | Planning | | Awards status | Not specified | | Contracts status | Not specified | ## Buyer | Field | Value | | --- | --- | | Main buyer | UNITED KINGDOM INDUSTRIAL FUSION SOLUTIONS | | Locality | CULHAM | | 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 | Not specified | ## CPV Codes ### Divisions - 71 - Architectural, construction, engineering and inspection services ### Codes - 71320000 - Engineering design services - 71323100 - Electrical power systems design services - 71323200 - Plant engineering design services ## Release History - 16 Jan 2026 at 16:05 - Planning - UK2 - Preliminary Market Engagement Notice - https://www.find-tender.service.gov.uk/Notice/004045-2026 ## Documents - https://www.find-tender.service.gov.uk/Notice/004045-2026 16th January 2026 - Preliminary market engagement notice on Find a Tender ## Notice URLs - https://ukifs.delta-esourcing.com/respond/7JNTY86XYK - https://ukifs.delta-esourcing.com/tenders/UK-UK-Culham:-Engineering-design-services./7JNTY86XYK - https://www.legislation.gov.uk/ukpga/2023/54/contents ## Provenance This Markdown file is an alternate public rendering of the D3 Tenders contract record.
