Wilson power transformers at Associated British Ports Southampton

Projects
Port of Southampton

Critical power supply upgrade

The Port of Southampton is Britain’s most productive port, handling £40 billion of UK exports annually, as well as 900,000 vehicles and over 2 million cruise passengers. As the second largest container terminal in the UK, managing 1.5 million twenty-foot equivalent units (TEUs) every year, the port is a critical gateway to both European and global markets.

Scope of Work	Two 12/24MVA 33/11-6.6kV CER UKPN Wilson Power Transformers 1MVA 11-6.6kV/433V Wilson e3 Ultra Low Loss Amorphous® Transformer

To support ongoing infrastructure upgrades by Associated British Ports, we delivered two 12/24MVA 33/11-6.6kV Wilson Power Transformers to provide vital power for port operations. These transformers play a key role in maintaining and scaling the port’s electricity supply to support its expanding logistics and transport capacity.

Additionally, we supplied a 1000kVA 11000-6600/433V Wilson e3 Ultra Low Loss Amorphous® Transformer as an auxiliary unit to support backup and supplementary systems across the site. Known for its reduced losses and long-term cost efficiency, the Wilson e3 complements the high-capacity power transformers by boosting energy resilience and operational sustainability.

Commissioning was completed by Southern Voltage Services and Shaard Energy Services Ltd, who ensured seamless installation and energisation. This project highlights the increasing demand for dependable, efficient, and scalable power infrastructure at major UK logistics hubs. With extensive experience in delivering specialised industrial solutions, we remain a trusted partner for complex infrastructure developments such as the Port of Southampton.

The power transformers provided are designed by Wilson Power Solutions and approved by UKPN. The cooling offers a Continuous Emergency Rating (CER), which allows one transformer to support the full load of the site in the case of planned maintenance or failure.
