    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 ...

    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 ...

    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 ...

    Practical considerations in energy efficient compressor set-point control strategies 

    Van Tonder, A.J.M.; Marais, J.H.; Bolt, G.D. (IEEE, 2014)
    Compressed air supply and demand strategies have received significant attention since integrated demand management was initiated by Eskom. Due to the expensive nature of this vastly utilised energy carrier, every increase ...

    Reconfiguring mining compressed air networks for cost savings 

    Bredenkamp, J.I.G.; Van der Zee, L.F.; Van Rensburg, J.F. (IEEE, 2014)
    The ever-growing human population, limited energy resources and the effect of greenhouse gas emissions have become major global concerns for the energy sector. This includes the electricity generation sector. This dilemma ...

    Developing a dynamic control system for mine compressed air networks 

    Van Heerden, S.W.; Pelzer, R.; Marais, J.H. (IEEE, 2014)
    Mines in general, make use of compressed air systems for daily operational activities. Compressed air on mines is traditionally distributed via compressed air ring networks where multiple shafts are supplied with compressed ...

    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 ...
