Details

Background

The Spherical Tokamak for Energy Production (STEP) programme aims to deliver a prototype fusion energy plant by 2040, while also developing a robust fusion supply chain and a pathway to commercial fusion. Achieving this vision requires the delivery of an unprecedented and complex engineering design, alongside a major infrastructure project involving a large and diverse supply chain, all on an ambitious timeline. STEP is a central component of the UK’s long-term vision for commercial fusion energy and national energy security. The STEP programme directly supports the UK Government’s strategic objectives in clean energy innovation, energy resilience, and global technological leadership. Fusion energy is recognised as a potential transformative low-carbon energy source, offering long-term reductions in reliance on fossil fuels and mitigating exposure to volatile international energy markets. System Partners Opportunity UKFE is seeking to procure suitable Suppliers (an individual organisation, consortium or joint venture) across 5 Lots to support the delivery of the UK’s prototype fusion energy plant. The information for each Lot below represents an overview of the requirements and the definitive statement of UKFE’s requirements is set out in the Capability Statements provided with the procurement documents. The term of the Contract under each Lot will be two (2) years with an option to extend for one (1) year on two (2) occasions, at the discretion of UKFE. The total contract length will not exceed four (4) years. The maximum value for each Lot is set out below and includes expenses (excluding VAT) for the initial term and for the extension period.

Documents

Before you bid on this tender

A quick checklist to help you decide whether to bid and prepare a compliant submission for this manufacturing & supply opportunity. Always verify the details on the official source.

  • Confirm the exact closing date and time (and time zone) on the official portal — deadlines are strict and can be revised by a corrigendum.
  • Read the full notice and every attached document, including the scope, specifications and any bill of quantities or terms of reference.
  • Check the eligibility criteria — prior similar experience, annual turnover, certifications and registrations — and make sure you qualify before investing effort.
  • Prepare any earnest-money deposit (EMD) or bid security and the required formats early; missing or wrongly-formatted documents are a common cause of rejection.
  • Note how bids must be submitted (online or physical), in what format, and whether a digital signature or portal registration is required.
  • Watch for corrigenda and clarifications right up to the deadline — requirements and dates can change.
