Dovecote Park

Wilson e3+

Transformer Replacement with Voltage Management Solutions

Inrush currents from motor loads at Dovecote Park were creating short-duration voltage dips on the low voltage network. Due to the proximity of a wind turbine on the 11kV network, the effect of these events was amplified. The worst-case scenario at Dovecote Park prevailed during typical peak demand periods, when the turbine was not generating power.

The existing transformer was replaced with a 3MVA Wilson e3+
Ultra Low Loss Amorphous Transformer coupled with a 9-position on-load vacuum tap changer. The primary purpose being to reduce the grid swing and mitigate the risk of failure to critical plant and equipment from under-voltage. This results in 68,426kWh, 14.4 tCO2 and £12,316 annual savings.

University of Warwick

Wilson e3

The Interdisciplinary Biomedical Research Building (IBRB)

Over the years, Wilson Power Solutions supplied 21 transformers to the University of Warwick, 16 of these were ultra and super low loss amorphous transformers in the following ratings; 500, 800, 1000, 1250, 1500, 1600 and 2000kVA. Upgrading to Wilson e2 and Wilson e3 meant that the university decided to install transformers that go beyond the Ecodesign specifications. Comparing the regulated industry-standard transformers and the Wilson lower loss transformers, the University of Warwick saves annually 213MWh. Over the lifetime of these transformers (30 years), they will have saved the university 6.4GWh of electricity, 1,480 tonnes of CO2 emissions and over a million pounds of financial savings.

The Interdisciplinary Biomedical Research Building is one of the most environmentally sustainable buildings on campus acting as the epitome of the university’s net-zero plans and pledges set to act on the climate emergency. 1250kVA Wilson e3 Ultra Low Loss transformer was installed at the centre and it will help mitigate 109 tCO2 and 472MWh over 30 years of operation.

TESCO

Wilson e2

Energy Efficiency Initiative

Tesco has committed itself to a zero-carbon status by 2050, an admirable goal that has required the retail giant to alter the way it operates its infrastructure. As a result, the company has actively sought out ways to reduce its energy wastage, and began looking for low-loss transformers that were up to the task.

The unique amorphous core in our Wilson e2 distribution transformers was exactly the upgrade Tesco were after, offering the most energy efficient solution for the company’s estate. Exceeding their demands for a low-loss transformer, the e2 delivers a super low loss solution, providing incredibly minimal core losses. Over 90 Wilson e2 transformers have been installed to date, with no failures or recalls required. It has reduced Tesco’s wasted energy by over 9 million kWh and saves the company over an estimated £810,000 a year.

NHS

Wilson e2

Transformer Replacement Project

The NHS is one of the largest energy users in Europe, with spending in excess of £400 million a year. With its highly ambitious carbon reduction target of 80% by 2050, the service is constantly looking for any ways in which it can save both energy and money.

With this in mind, when The University Hospital of South Manchester was looking to replace its distribution transformer they were keen to maintain their reputation as the “greenest” hospital in the UK. They were aware that super low loss amorphous transformers provided guaranteed energy savings through reduced core losses, but we helped them learnt that they could find additional savings by using inbuilt voltage management capabilities. As a result the Trust sourced seven Wilson e2 replacement supply transformers to obtain both these features.

The result was an overall reduction of 6% in energy consumption and savings of £31,000 a year, meaning the transformers paid for themselves in less than 3 years. With a minimum life expectancy of 25 years, this is a fantastic case study in how large organisations can make a practical and noticeable difference in their energy efficiency without compromising on their current usage.

McCain

Wilson e2

Transformer Replacement Project

Founded on “good and responsible” business ethics, when McCain were faced with replacing their old transformer they sought out a solution that matched their approach to sustainability and efficiency. The decision to install a Wilson e2 was based on the transformer’s super low loss capacity, reducing both costs and energy wastage, managing to cut out 12 tons of CO2 a year from McCain’s carbon footprint. The Wilson e2 has subsequently reduced costs by £22,500 per year while also reducing the energy wasted by over 272,000 kWh.

ASDA

Wilson e2+

Voltage Regulated Super Low Loss Amorphous Transformer

The commitments made by ASDA to reduce their energy usage lead them to discover our super low loss amorphous Wilson e2+ transformer. Not only does the transformer help reduce overall energy losses in the amorphous core, but the additional Voltage Management System means ASDA can control its voltage output dynamically, giving their stores extra power as and when they need it.

The installed distribution transformers have cut energy usage by 7%, saving them over £25,000 a year in unnecessary costs. The project has nearly paid for itself twice over since installation, and with our recommended minimum transformer life of 25 years they will remain an excellent long term investment.

Smurfit Kappa

Wilson e2

Transformer Replacement Project

After performing an energy efficiency review, Smurfit Kappa realised they could make significant savings by installing transformers with Voltage Management equipment. The Wilson e2 helped them achieve the savings they were after, and the reduced supply voltage combined with the efficiency provided by the super low loss amorphous metals technology means Smurfit Kappa saves £10,500 annually and they have reduced their energy usage by 99,176 kWh. The Wilson e2 achieved full payback in less than 3 years at their Staylbridge site, and their energy usage went down by 3.5%.
