## Summary

The procurement process, led by Nuclear Restoration Services Limited, entails the maintenance of Extra High Voltage Electricity Switchgear for the period from 2026 to 2031. Categorised under services, the procurement pertains to the repair and maintenance of electrical distribution equipment specifically located at Dungeness A, Maentwrog, Trawsfyndd, and Wylfa in the UK. The procurement has reached the award stage, having been completed on 31st March 2026. The process utilised a limited procurement method without prior publication due to the procurement's classification as outside the scope of standard directives.

The nature of the services required suggests that businesses with expertise in high voltage electrical infrastructure would be well-suited to this contract. Large-scale enterprises like National Grid Electricity Transmission, having already participated, are exemplary candidates, though there is room for other well-equipped suppliers to engage in such critical projects, which ultimately support the maintenance and efficiency of national electricity distribution networks.
