The impact of reducing mine chilled water supply during periods of low production
(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 ...
Modernising underground compressed air DSM projects to reduce operating costs
(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 ...
Energy efficiency through variable speed drive control on a cascading mine cooling system
(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 ...
Strategies for energy efficiency funding in the absence of industrial Eskom-IDM support
(IEEE, 2014)
In the absence of industrial Eskom-IDM (Industrial Demand Management) funding, industry is forced to look elsewhere for energy efficiency project funding. This paper outlines various taxes and government incentives for ...
Implementing DSM interventions on water reticulation systems of marginal deep level mines
(IEEE, 2014)
South Africa's steep electricity tariff increases have forced the mining industry to be more cost effective. One way is by implementing demand side management (DSM) projects. Energy saving priorities focused mainly on mines ...
Benefits of improved performance monitoring of mine cooling systems
(IEEE, 2014)
Mine cooling system components are an integral part of a mine's ventilation system. A mine's reliance on these capital intensive components are set to increase as mines deepen. Mine cooling systems consume up to a quarter ...
Practical considerations in energy efficient compressor set-point control strategies
(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 ...
An integrated energy efficiency strategy for deep mine ventilation and refrigeration
(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 ...
