AECOM Secures Key Role in UK’s £200M Fusion Prototype Program

  • AECOM, as part of the ILIOS consortium, has been appointed Construction Partner for the initial £200 million phase of the UK’s Spherical Tokamak for Energy Production (STEP) program.
  • The STEP program aims to build a prototype fusion power plant at West Burton in Nottinghamshire, targeting commercial viability by 2040.
  • The project, sponsored by the UK Government’s Department for Energy Security and Net Zero, has a potential total value of up to £10 billion across future phases.
  • ILIOS is led by a Kier Nuvia joint venture, with AECOM, Turner & Townsend, and AL_A providing specialist support.

The UK’s STEP program represents a significant investment in fusion energy, a technology poised to become a critical component of future low-carbon energy systems. AECOM’s involvement, valued at £200 million initially with potential for £10 billion, underscores the growing demand for specialized engineering and construction services in the nascent fusion sector. This project positions AECOM to capitalize on the long-term growth potential of fusion energy, but also exposes them to the inherent risks associated with pioneering a complex and capital-intensive technology.

Funding
Whether the program secures the full £10 billion in funding over its lifecycle will be crucial for AECOM’s long-term revenue stream and exposure.
Technology Risk
The success of the STEP program hinges on overcoming significant technological hurdles inherent in fusion power generation, which could impact project timelines and costs.
Geopolitical
The UK’s commitment to fusion energy, and AECOM’s involvement, may be influenced by broader geopolitical shifts and energy security concerns.
