The UK Atomic Energy Authority (UKAEA) announced on 14th October 2021 that Ardeer in North Ayrshire is one of five shortlisted sites under consideration as the location for the Spherical Tokamak for Energy Production (STEP) programme.

STEP, supported by an initial £222m in funding from the UK government, aims to design and construct a prototype fusion energy plant capable of providing an environmentally-friendly source of electricity. The programme is targeting a concept design by 2024, with operations planned to begin around 2040.

Lessons learned during the construction and initial operation of STEP will enable the future development of a fleet of commercial fusion plants.
