This is the story of a remarkable product manufactured by a similarly remarkable family-run power engineering company, and how it has made significant inroads into the supply transformer market. From technology to market in under two years the Wilson e2 is now specified by leading commercial organisations and blue chip companies.
Leeds based Wilson Power Solutions (WPS) is proud to celebrate the success of its e2transformer range - the UK’s most energy efficient distribution transformer. This is the UK’s first and only super low loss amorphous distribution transformer that substantially reduces operating costs and CO2 emissions. As a result the e2 is already delivering significant energy savings to businesses committed to driving down their energy costs and radically improving their carbon footprint.
The Wilson e2 - the highly efficient transformer brand
The unique e2 is the result of pioneering technology from WPS, a company that is wholly committed to engineering excellence, product innovation and the provision of cost efficient power solutions aimed at reducing environmental impact. The cause for celebration at WPS is that the e2 is a ‘home-grown’ product borne from the collaboration of a small R&D team with an equally small R&D budget at its disposal! Using proven technology and design the Wilson e2 transformers combine amorphous metal cores with low resistance copper conductors to provide unrivalled savings in both core and copper losses.
Groundbreaking Energy Savings -Reducing operating costs by up to 15%
Since its launch just two years ago the Wilson e2 has been able to demonstrate startling
payback results on the initial investment required. The e2 provides guaranteed savings through reduced transformer losses. These savings can be accurately forecast depending on the size of the unit and typical load. For example a 1000kVA transformer at 70% load will save 28,000 kWh (~£2250) per year through loss savings and achieve payback on the additional investment in just 2.5 years. Significant additional savings can be achieved through in-built Voltage optimization capabilities where site supply Voltage is high and Voltage dependent loads are present.
The Wilson e2 transformer is helping numerous customers including NHS hospital trusts such as Whipps Cross University Hospital, the Natural History Museum and leading supermarkets, to reduce their operating costs and lower their carbon emissions. ASDA and Tesco have already recognised the very considerable benefits that Wilson e2 transformers are delivering to their bottom line.
Daniel Travers from the Tesco Corporate Purchasing team commented: “Tesco is installing the Wilson e2 transformer into its estate as we believe it will assist us to improve our emissions target whilst helping us achieve our commercial constraints. The team at Wilson Power Solutions have shown strong technical expertise and customer service.”
The smart Voltage Optimisation solution for HV applications
11-14% kWh reduction
An additional -5% to +7.5% tapping range is built into the Wilson e2 at no extra cost. This enables the operating company to optimise voltage supply from 415V to 380V according to the needs of an individual site, wherever the incoming supply is at medium voltage. This solution avoids the need to invest in supplementary downstream voltage optimisation equipment and represents an extremely cost effective VO for HV installations with a typical reduction of 12% in kWh consumption. The transformer also integrates smoothly with current installations without the risk of disruption. Endorsing the VO capabilities of e2 for additional savings, the Hilton Hotel in Portsmouth saw a significant kWh reduction of up to 14% after replacing their transformer. Similarly, food manufacturer Cranswick bacon recorded an 11% reduction despite increased production levels.

New – the Wilson e2 plus
The new Wilson e2 plus is currently undergoing final trials and is being introduced to provide an ‘intelligent’ Voltage regulation solution where supply to site fluctuates or a constant (+/- 1.25%) output Voltage is required. e2 plus comes with an automatic voltage regulator that operates on load tap changers to provide stabilised site voltage.
