Eskom KZN Buildings

Energy Efficient Lighting Project

Eskom called on Magnet to investigate the potential savings that could be achieved in all of their KwaZulu-Natal buildings. A comprehensive study performed by Magnet revealed a possible saving in Eskom’s electrical capacity by 0.433MW.

Magnet’s objective for this project was to reduce the lighting load at all Eskom buildings in the greater KZN area. The project involved the following:
  • Replacing existing light fittings with equivalents of higher energy efficiency
  • Retrofitting existing fittings with new control gear e.g. magnetic ballasts were replaced with electronic control gear
  • Re-lamping existing fittings with more efficient lamps where necessary
  • Leaving existing fittings as is, where necessary

The project took place at over 100 sites in Eskom’s Eastern region, where 11 000 light fittings were installed. The project saved 45% of the initial load, with an accumulative saving of 440kW. These savings were verified by the University of North West.

This lighting project was completed in 2011 at 6 eThekwini sites and further sites shall be upgraded in the near future.
