Secretary of State for Energy Security and Net Zero, Claire Coutinho, and Minister for Nuclear and Renewables, Andrew Bowie, announce industry competition to find engineering and construction partners for the UK’s prototype fusion energy plant.

STEP (Spherical Tokamak for Energy Production) aims to demonstrate net energy from fusion, stimulating commercialisation of a new low-carbon energy source. This will help tackle climate change and meet future global energy demand.

Today, Secretary of State for Energy Security and Net Zero, Claire Coutinho, and Minister for Nuclear and Renewables, Andrew Bowie announced the search for engineering and construction partners to design and build the UK’s prototype fusion plant. Industry will be the driving force behind fusion becoming part of the world’s future energy supply.

The multi-stage competition launched on 22 May 2024. It will seek industry partners – one in engineering and one in construction. They will form a world-leading public-private alliance led by UK Industrial Fusion Solutions Ltd (UKIFS) to deliver the STEP prototype fusion plant. UKIFS is a wholly owned subsidiary of UK Atomic Energy Authority (UKAEA) Group.

UKAEA will be one of the three ‘Whole Plant Partners’ to STEP. It will contribute specialised expertise and resources as part of the integrated alliance with the two successful bidders.

STEP aims to demonstrate net energy from fusion in the 2040s. It will be built at West Burton, the site of a former coal-fired power station site in Nottinghamshire.

Awarding of contracts to the successful engineering and construction partners would be in late 2025 to early 2026. Intended to be long-term partnerships. In the initial contract period until 2029, the contracts have an initial combined value of hundreds of millions of pounds . The phased contracts will build progressively in-line with the development of the prototype plant.

A crucial part of STEP’s mission is to develop a world-leading fusion supply chain. This will ensure the UK remains at the forefront of a new technology and emerging industry.

The programme aims to pave the way for the commercialisation of fusion and the potential development of a fleet of future plants around the world.

Minister for Nuclear and Renewables, Andrew Bowie, said:

Fusion could provide a near limitless source of energy and the UK is leading the way in trying to harness this power and deliver long-term energy independence.

Building STEP is a major opportunity for the sector and will provide investment and jobs in a former industrial area of Nottinghamshire.

Paul Methven, CEO, UK Industrial Fusion Solutions, said:

The launch of our STEP procurement for engineering and construction partners will be a critical milestone on the journey to demonstrate and then commercialise fusion energy.

Our industrial model will combine the best of public and private sectors in an integrated alliance to drive economic and industrial opportunities for the UK on a significant scale.

Together with our partners, we will leverage the UK’s internationally renowned status in fusion research and development to lead the delivery of a fusion energy sector that will help meet the global energy demand in the second half of this century.

Following the appointment of these strategic partners, will flow a vast range of other opportunities for the broader supply chain. Details of this will unfold in due course.

STEP provides an enormous opportunity as a catalyst for growth and regeneration for communities surrounding the West Burton power station site, announced as STEP’s home in October 2022.

The programme will create thousands of highly skilled jobs during construction and operations. It will also attract other high-tech industries to the Midlands region.

Fusion energy has great potential to deliver safe, sustainable, low carbon energy for generations to come.

Sometimes described as the ultimate energy source, fusion is based on the same processes that power the Sun and stars. When a mix of two types of hydrogen (deuterium and tritium) are heated to form a plasma that’s 10 times hotter than the core of the Sun, they fuse together to create helium and release huge amounts of energy.

STEP’s Whole Plant Partner procurement will be live from the 22 May. Once the initial stage of the selection process is complete, UKIFS will enter detailed discussions with shortlisted companies.
