Converting an ice storage facility to a chilled water system for energy efficiency on a deep level gold mine
(2015)The South African gold mining sector consumes 47% of the mining industry’s electricity. On a deep level gold mine, 20% of the energy is consumed by the refrigeration system. The refrigeration system cools 67 ˚C virgin rock ... -
Cost and energy savings on mine surface cooling systems
(North-West University (South Africa) , Potchefstroom Campus, 2017)The South African national power utility, Eskom, is struggling to meet the high electrical energy demand. The problem is due to the shortage of generating capacities as a result of delays in the building of new power ... -
Developing a dynamic control system for mine compressed air networks
(2014)Mines in general, make use of compressed air systems for daily operational activities. Compressed air on mines is traditionally distributed in two typical fashions. Firstly, direct pipe feed systems for single shafts or ... -
Developing ESCO procedures for large telecommunication facilities using novel simulation techniques
(North-West University, 2006)Peak electricity demand in South Africa will exceed the available operational generation capacity in 2007. The state utility Eskom is addressing this challenge, inter aha, with the implementation of the Demand-side ... -
The development and implementation of an energy management information system for industries
(North-West University (South Africa), 2020)There is a global drive to reduce energy consumption and improve energy efficiency. These drivers include the taxation of carbon emissions and the increase in energy costs. Companies therefore need to improve their operational ... -
The development of a system to optimise production costs around complex electricity tariffs
(North-West University, 2012)Rising South African electricity prices and reduced sales following the 2008 economic recession have led cement manufacturers to seek ways to reduce production costs. Prior research has shown that reduced electricity costs ... -
Development of an energy management solution for mine compressor systems
(North-West University, 2010)Eskom is under increasing pressure to provide reliable and sustainable electricity. Demand Side Management (DSM), offers a short– to medium–term solution to this problem. During 2009, the mining sector consumed approximately ... -
A dynamic optimal control system for complex compressed air networks
(North-West University (South Africa) , Potchefstroom Campus, 2016)Mines use large compressed air networks to supply shafts and processing plants with compressed air. These networks can be complex where multiple compressors are located at different locations. To add to the complexity of ... -
Energy management for improved profitability of small manufacturing enterprises
(North-West University (South Africa) , Potchefstroom Campus, 2015)Approximately 75% of small, medium and micro enterprises (SMMEs) created in South Africa (SA) fail in the first year. This is a serious socio-economic problem as SMMEs in South Africa employ over 60% of the workforce and ... -
Identifying demand market participation opportunities available in cement plants
(2014)South African cement manufacturers are under financial pressure. Sales have declined due to the 2008 recession and electricity costs have tripled from 2005 to 2012. Electricity cost savings are therefore more important ...
