Various energy efficiency initiatives were undertaken at our operations during the Year, including: » continuous roll-out of high efficiency motors at all the operations; » replacement of all incandescent and fluorescent lights with LED lights; » installation of variable speed drives where applicable; » installation of heat pumps and solar heating systems at change houses including the replacement of old shower heads with EE (low flow) heads; » optimisation of the control of all the power factor correction banks at all operations to ensure optimal performance; and » load management carried out through the real time energy management system, monitoring the maximum demand in the control room to ensure that systematic plant start-up and hoisting during peak times is limited to a minimum.
