A record-breaking £2.5 billion of additional funding has been announced this week by Chancellor of the Exchequer, Rt Hon Rachel Reeves, to accelerate the development of the world’s first prototype fusion power plant in the UK.

Known as Spherical Tokamak for Energy Production (STEP), the pioneering facility will be constructed on the site of the former West Burton A coal power station near Retford and Gainsborough in Nottinghamshire. First selected in 2022, the location is set to become a global centre of clean energy innovation, with the project expected to create over 10,000 jobs across construction, engineering and operations.

The announcement marks a major step forward in the government's ambition to become a "clean energy superpower", transforming an area long associated with fossil fuel energy into the heart of a new green revolution.


STEP represents a groundbreaking leap in energy technology. The process involves fusing hydrogen isotopes—deuterium and tritium—by heating them to over 150 million degrees Celsius and containing them within a powerful magnetic field. The resulting energy is converted into steam to drive turbines and generate electricity, much like a conventional power plant, but without greenhouse gas emissions.

Paul Methven CB, CEO of UK Industrial Fusion Solutions, the body responsible for delivering STEP, welcomed the investment: "The UK is the world leader in fusion energy research today, and STEP is the beacon programme that aims to take fusion from research to commercial success, generating high quality jobs, multiple spin offs and boosting the economy nationally and in the East Midlands where we will build the first plant.

"Securing a global lead in such a vital new technology requires bold action; the government has rightly been bold today and we look forward to delivering the practical steps that will realise the vision of the UK leading in this exciting new sector."
