We have developed our very own tariff clock based on ESKOM tariff structure for our time-of-use clients. This clock uses a 24-hour clock mechanism and simply shows people when they are in or close to peak, standard or off-peak zones during the day. One is now able to schedule or avoid using high powered machinery and equipment by just timing these activities appropriately and thereby making substantial savings in electricity bills. The concentric rings also show the differences on weekdays, Saturdays and Sundays. Last but not least, it can also help tell the time.
We have completed three intensive energy audits at three large distilleries in the Western Cape. This included a month of energy data collection through sub-metering at the departmental as well as the equipment levels to get a highly accurate energy demand breakdown.
The assessment included an analysis of the steam system, including an analysis of the boiler stack flue gases and condensate return. A number of detailed business cases were developed to present energy saving opportunities. It also included an analysis of the existing metering systems and recommendations were made to increase the effectiveness of the existing measurement systems. Finally, a number of behaviour change initiatives were recommended.
