Cost savings on mine dewatering pumps by reducing preparation- and comeback loads
Cilliers, C.; Kleingeld, M.; Van der Zee, L. (IEEE, 2014)With the introduction of a time-of-use (TOU) tariff structure by Eskom, the implementation of projects that shift load from peak TOU times to times of the day when electrical energy is less expensive has increased. To ... -
Energy efficiency through variable speed drive control on a cascading mine cooling system
Van Greunen, D.; Schutte, A.J.; Kleingeld, M. (IEEE, 2014)An ever-expanding global industry focuses on energy supply and use. Cost-effective electrical energy production and reduced consumption pave the way for this expansion. Eskom's demand-side management (DSM) initiative ... -
Finding the four qualities of intelligent industrial reporting
Botes, L.A.; Hamer, W.; Van Jaarsveld, S.; Kleingeld, M. (Stellenbosch Univ, 2019)Internationally, innovation and technology are driving change through concepts such as ‘Industry 4.0’. However, due to various constraints, South Africa is lagging behind in this transformation. Furthermore, local ... -
A holistic approach to presenting DSM project results
Booysen, W.; Van Rensburg, J.F.; Kleingeld, M. (IEEE, 2014)A slight variance in dataset quality or baseline model accuracy can affect the level of confidence at which DSM project results are calculated. General measurement and verification (M&V) guidelines mitigate this inherent ... -
The impact of reducing mine chilled water supply during periods of low production
Schoeman, W.; Schutte, A.; Kleingeld, M. (IEEE, 2014)As part of the Demand Side Management (DSM) initiative, Eskom partially funds load management and energy efficiency projects. Large industries are therefore willing participants in the Eskom funded electricity savings ... -
An integrated energy efficiency strategy for deep mine ventilation and refrigeration
Schutte, A.J.; Kleingeld, M.; Van der Zee, L. (IEEE, 2014)Mine-cooling and ventilation energy cost saving projects are implemented ad hoc and scattered throughout the system. Therefore, an overhead view and strategy is needed to help realise the total savings available on the ... -
Modernising underground compressed air DSM projects to reduce operating costs
Kriel, C.J.R.; Marais, J.H.; Kleingeld, M. (IEEE, 2014)Compressed air is an energy intensive utility that is frequently used in the deep level mining industry. Most compressed air networks are designed to ensure ample compressed air supply to consumers. This has created the ...
