Tesco Transformer Specification Programme

With a significant built estate, Tesco’s commitment to achieve zero carbon status by 2050 sets a tough challenge. This is why the engineering team is focused on all areas of energy consumption to see where the organisation can introduce savings and streamline operations to reduce carbon.

Considering Tesco’s significant annual electrical consumption, transformer losses represent a lot of electricity. Improving this, even by a small margin, would therefore provide a significant saving. In 2008, the Tesco engineering team developed tougher new engineering specifications and started looking for Super Low Loss units. Wilson e2 was the only product to meet the ambitious specifications and also offered a unique technology with an amorphous core that could provide significant additional loss savings.

Scope of Work	Ninety Wilson e2 Super Low Loss Amorphous® Transformers

Working alongside Tesco, we adapted product specifications to serve Tesco’s requirements better and modified the product to include an extended taping range as standard. Following these product development activities, Tesco specified the Wilson e2 transformer for new stores in 2009. In addition to the savings Tesco achieves through reduced transformer losses, the Wilson e2 comes with an extended tapping range that allows the reduction of voltage to the site at the source. This eliminates the need for dedicated voltage management equipment, offering an extremely cost-effective 2-in-1 solution with added benefits of reduced plant footprint, less cabling and maintenance requirements.
