Some of the more successful projects include: Š continuous roll-out of high-efficiency electrical motors at all the operations; Š continuous optimisation of the control of all the power factor correction banks at all operations to ensure optimal performance; Š 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; Š pump control on all pumps to ensure pumping occurs at off-peak times; Š variable speed drives on conveyors; Š motion sensors to regulate lighting in low-occupancy areas (tests at Finsch and Cullinan); Š Group standard on soft start on all motors of thus reduce maximum demand (implementation is phased in over five years); Š replacement of incandescent bulbs with energy-efficient lighting; Š correct sizing of electrical motors to ensure that they operate in the high-efficiency band; and Š renewable energy (mainly solar power through photovoltaic panels) is investigated to be used in limited applications, specifically in office and change house applications.
