What is being bought

Published requirement description

The UK Atomic Energy Authority's main HV Pulsed Power supply to the Culham site is via a dedicated overhead line fed directly from the National Grid at 400kV, transformed down to 33kV. The main distribution substation for this supply is J5 substation, located at the north end of Culham Campus. The substation is undergoing a significant upgrade in 2026. The scope is for part of that upgrade. It covers the design, manufacture, delivery, installation, and commissioning of:

  • A replacement 415V AC Distribution Board,
  • 3 replacement auxiliary supply cubicles including isolation transformers,
  • A new 400/33 kV inter-trip panel to transfer trip signals between the 400 kV and 33 kV substations, and
  • A new 400 kV revenue metering panel capable of metering the 400 kV supply for each of the three Super-Grid Transformers (SGTs). All of the above must be capable of integration with a new IEC 61850 SCADA system.
