Description
The main HV Pulsed Power supply to the Culham site is via a dedicated overhead line fed directly from the National Grid at 400kV and transformed down by three 90 MVA 400/36kV super grid transformers (SGT's) normally operated in parallel. Original installation of the Super-Grid Transformers was installed over 40 years ago and original spares are practically non-existent. They are an aging asset, with cooling becoming more critical with weather and with the potential of new increased loading due to new customers on site. Therefore, replacement of the 5 remaining Blast Air Coolers is important to extend the lifespan of the equipment. The Blast Air Coolers provide cooling to the oil inside the transformer tank. There are 4 Blast Air Coolers located on each SGT, for a total of 12 units. In 2016, the first phase of this replacement was carried out, replacing 7 of the original units. This project is to replace the remaining 5 original units.

Engagement process description
UKAEA has previously conducted pre-market engagement for the procurement of the SGT Cooler Units. A quote was received from a potential supplier; the value of this quote indicated that this procurement would be over threshold and therefore needed to be procured through a Procurement Act 2023 Compliant procedure. UKAEA has not done any further premarket engagement for this requirement.
