Invitation to Express Interest
UKAEA invites expressions of interest from potential investment partners who have the capability and ambition to participate in this landmark opportunity. This initiative builds upon recent market engagement to deepen understanding of the supply chain and identify partners for subsequent development phases.
Participation in this Expression of Interest (EOI) process is mandatory to be considered for further stages.
Vision for Culham Campus Development
Our aim is to transform Culham Campus into a globally recognised centre of excellence by establishing a bold, collaborative partnership between the public sector and a strategic private investor. Culham is the UK’s first designated AI Growth Zone, anchoring a vibrant cluster of fusion-relevant organisations alongside AI and high-performance computing capabilities.
This partnership will accelerate fusion energy development, create a vibrant new industry sector, and support the UK Government’s Net Zero research goals.
Scope of Opportunity
UKAEA intends to appoint a long-term investment partner to:
- Lead the development of a commercially driven masterplan and delivery strategy for the campus, aligned with UKAEA’s goals and shared vision.
- Secure funding and oversee phased development, redevelopment, refurbishment, and repurposing of campus plots in line with the masterplan.
UKAEA intends to release a minimum of 10 acres of land and its reconfigured power connections as the first investment opportunity. The high voltage infrastructure provides connections to both 132kV and 400kV electricity grids with available spare capacity to initially deliver approximately 100MW of steady state, dual resilient power for the delivery of a mission-led AI data centre, potentially adjacent to other use cases (either Government led or commercial) – ideally with a focus upon driving near term economic growth and longer-term economic opportunities towards realisation of UK Net Zero. UKAEA expects that a portion of this facility (up to 20MW, or equivalent services) would be available on demand for fusion and broader R&D research.
UKAEA is continuing to actively explore the possibility of expanding the acreage of this first development plot(s) and in doing so allow proposals for a >100MW AI data centre (potentially up to a maximum limit of 500MW). To this end, the invitation to participate documents following the expression of interest process will include a final set of parameters within which suppliers will be permitted to create proposals.
