Horizon Nuclear Power has achieved a 25% improvement in operational efficiency across the project


Horizon Nuclear Power, a UK energy company developing a new generation of nuclear power stations, required a solution for the Wylfa Newydd project that was 100% complete and accurate, to enable the effective tracking of over 1 million documents, multiple suppliers and at peak around 9,000 onsite workers during the construction program. The Horizon IT teams wanted to create a solution that created a digital twin, providing an IT blueprint for other new nuclear projects globally.

Business challenges

  • Obligations to meet Nuclear Site License and Office for Nuclear Regulation requirements
  • Having to prove full control of activities on the project sites and suitability of organization, site and design
  • Requiring a solution that is 100% complete, accurate and able to track over 1 million documents across multiple suppliers
  • Aim to create a solution that creates a digital twin and provides an IT blueprint for other new nuclear projects globally

We are incredibly proud of the solution we have implemented using Aconex. It is a blueprint for all major capital construction projects across all industries.
