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 ...
Reconfiguring mining compressed air networks for cost savings
(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 ...
The cost effects of DSM interventions on vertical roller mills in the cement industry
(IEEE, 2014)
Load management is a successful way to implement evening load reduction and load shift DSM projects on cement plants. However, finishing grinding in the cement production process requires accurate temperature control. To ...
Cost savings on mine dewatering pumps by reducing preparation- and comeback loads
(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
(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 ...
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 ...
Carbon dioxide pollution reduction through load shift projects
(IEEE, 2014)
Significant advances have been made in automation technology allowing systems to shift electricity consumption from peak periods to off-peak periods. Load shift projects have been implemented throughout South Africa for ...
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 ...
Simplified performance monitoring of energy systems
(IEEE, 2014)
Large energy consumers face mounting pressure due to recent energy cost increases, as well as regulatory requirements and limitations. Therefore, energy performance monitoring is an essential component of many modern ...
