Pick n Pay, South Africa

INTRODUCTION

Established in 1967, Pick n Pay is the second largest supermarket chain store in South Africa. The group has a portfolio of retail sites including supermarkets, clothing stores, express shops, pharmacies and mini markets.

Pick n Pay actively promote sustainable practices in every aspect of the business. The company are committed to minimising its environmental footprint by improving its energy and water efficiency and decreasing emissions throughout its store portfolio and supply chain facilities.

THE CHALLENGE

Powerstar South Africa were asked to determine if voltage optimisation could produce further energy consumption savings to two Pick n Pay supermarket stores in Port Alfred and Grahamstown. Both of which were already environmentally friendly stores.

The busy supermarkets are open 7 days a week and therefore it was crucial that Powerstar was able to improve efficiency without impacting on the stores operational hours or customers shopping experience.

THE SOLUTION

With average voltages of 238.5V at the Port Alfred store and 234.1V at Grahamstown, both were suffering from excess voltage supply which was causing high levels of energy consumption and increasing wear on electrical equipment. Through installation of Powerstar’s voltage optimisation technology the over voltage issues were corrected and the incoming power supply was cleaned and conditioned to help reduce wear on equipment, thus extending life expectancy and reducing maintenance costs.

SAVINGS AND BENEFITS

Following the installations of Powerstar voltage optimisation systems the stores are achieving higher than the minimum guaranteed savings, and the installation was completed with no disruption to store opening hours. As a fit and forget solution, customer shopping experience is also unaffected.
