Improved mine cooling system performance through the control of auxiliary systems
(North-West University, 2012)
Industrial and mining sectors are amongst the largest single energy consumers in South
Africa, making them a primary focus for implementing energy saving initiatives.
Refrigeration systems on mines are responsible for ...
Potential savings when re–instating mine DSM projects
(North-West University, 2012)
The increasing electricity demand in South Africa has lead to a shortage in electricity supply. In response to this problem Eskom has introduced multiple capacity expansion programs. Unfortunately the electricity shortage ...
A systems engineering approach to improve the measurement and verification process of energy services companies
(2014)
The extensive use of fossil fuels coupled with its decreasing availability has ignited many countries to enact policies on energy usage. Energy Services Companies (ESCOs) all over the world are implementing initiatives to ...
The integrated effect of DSM on mine chilled water systems
(2014)
The national electricity utility in South Africa, Eskom, is currently under pressure to supply
the increasing demand for electricity on a national level. To address this problem in the
short term, Eskom partially funds ...
Benefits of improved performance monitoring of mine cooling systems
(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 ...
Energy efficiency through variable speed drive control on a cascading mine cooling system
(2014)
An ever-expanding global industry focuses attention 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) ...
Modernising underground compressed air DSM projects to reduce operating costs
(2014)
Growing demand for electricity forces suppliers to expand their generation capacity. Financing these expansion programmes results in electricity cost increases above inflation rates. By reducing electricity consumption, ...
Benchmarking electricity use of deep-level mines
(North-West University (South Africa) , Potchefstroom Campus, 2016)
Electricity consumption, and the cost thereof, has become a large contributor to operating costs in deep-level mining in South Africa. Up to 60% of electricity used on deep-level mines can be attributed to five high power ...
Automation of compressor networks through a dynamic control system
(2014)
Compressed air makes up an important part of South African precious metal mining processes. Rising operational costs in the struggling mining sector increased the interest of the power utility, Eskom, and mine management ...
Measurement and verification of industrial DSM projects
(2014)
Energy cost-reduction projects implemented on complex industrial systems present several challenges. The involvement of multiple project stakeholders associated with programmes such as demand side management (DSM) further ...
