Customer

Save Hyper Pietermaritzburg, part of the wider The Save Group chain of supermarkets in South Africa, have a track record for delivering a wide variety of goods to customers at highly competitive prices. Established in 1987, the group has grown to one of the largest cash and carry brands in South Africa.

Challenge

Maintaining large premises with a wide range of stock, Save Hyper were faced with significant energy bills to ensure products were delivered to customer in the best possible quality. Refrigeration for fresh food in particular added significantly to their energy costs, as did maintaining a comfortable shopping environment, particularly during hot summers. Lengthy opening hours also contributed to higher consumption.

Solution

Powerstar was commissioned to perform an initial inspection of the site to look for opportunities to reduce significant energy costs. The site was found to have unstable and higher than necessary voltage supply, inflating energy costs and carbon emissions. This made them an ideal candidate for Powerstar’s voltage regulation technology, which intelligently stabilises incoming voltage and maintains it at a constant, optimal level.

Results

Following the installation of Powerstar voltage regulation, Save Hyper saw a reduction in their annual energy consumption of 11.48%, saving over 487,000kWh annually. Lower, more consistent voltage also means that on-site equipment is provided with power levels in line with design specifications, reducing wear and tear and extending longevity.
