UK2 - Preliminary Market Engagement Notice
Summary of the contracting process

Sellafield Limited, a sub-central government public authority based in Warrington, UK, is in the planning stage of a procurement process titled "Low Carbon Gas Provision." This involves understanding the potential for supplying low carbon gas aimed at supporting Sellafield’s 2030 targets. This procurement falls under the goods category with specific industry classifications related to hydrogen and mains gas. A pre-market engagement is scheduled, and interested parties have until 19th December 2025 to respond to the engagement requirements through the Nuclear Decommissioning Authority's tendering portal. The planned contract period is set from 1st April 2030 to 30th March 2035, with potential renewals up to 2036.

This tender offers substantial opportunities for businesses in the low carbon and energy sectors to collaborate on reducing carbon emissions. Companies specialising in hydrogen and rare gases, or those capable of adapting to low carbon gas supply, would be well-suited to participate in this opportunity. Given the significant contract value of up to £120 million, participation could play a pivotal role in business growth and environmental compliance. Vendors with expertise in providing continuous gas supply at scale or facilitating transitions from natural to low carbon gas will find this tender particularly advantageous. Such participation could lead to strategic partnerships and enhanced market positioning within the sustainable energy sector.

Planning Information

Pre-market engagement To respond to the UK2, interested parties should respond in the Nuclear Decommissioning Authority (NDA) tendering portal Atamis To access Click on View our Live Opportunities and search for C28470 https://atamis-2464.my.site.com/s/Welcome And also provide answers to the questions below: Sellafield would like to understand the potential for supplying low carbon gas to the site to support its targets in 2030 and beyond. The following questions are being asked: 1. Please provide your name, contact details, and email address so that we can keep you advised of any changes in the proposed procurement schedule. 2. Supply volume – Can the nominal demand be supplied wholly or in part with a low carbon gas? 3. Availability - When that may be available? 4. Pricing - What is the short- and long-term pricing structure (assume a 10-year requirement)? 5. Location - What options exist for local or arm’s length gas production? – i.e. will facilities that supply gas be co-located and Sellafield the only off taker or is production elsewhere? 6. Incentives - What support is available to enable transition away from purely natural gas? Either via incentive schemes or by other means 7. Continuity of supply - How will the integrity of supply be considered? The Fellside plant runs continuously, and it is expected that this supply is maintained in a similar manner to the current gas supply. If additional inspections or activities are required either as a precursor to accepting gas or as part of additional maintenance, then this should be identified. This also includes any changes through blends. 8. Carbon savings – Sellafield would like to understand the carbon savings in TeCO2e expected by switching to this product. 9. Are asset modifications necessary? How might the current system need to be modified to accept a low carbon supply. It is not expected that a detailed engineering assessment is required. An indication on applicability or what types of adjustments might be needed e.g. burners, pumps, pipework etc.
