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 ...
Improving efficiency of a mine compressed air system
(North-West University (South Africa) , Potchefstroom Campus, 2017)
Eskom supplies electricity to South Africa, which experienced a capacity margin shortfall. Energy savings
companies (ESCOs) implement demand side management (DSM) initiatives to reduce the power strain
on the electricity ...
Improving mine compressed air network efficiency through demand and supply control
(North-West University (South Africa) , Potchefstroom Campus, 2017)
Eskom is in a position where they are producing sufficient electricity, although rapid expansion
and an increase in demand throughout various sections in South Africa can be expected in the
future. Large electricity ...
An improved baseline model for a mine surface cooling plant DSM project
(North-West University (South Africa) , Potchefstroom Campus, 2017)
Several challenges exist for the successful implementation of energy cost reduction projects on industrial systems. Due to the potential large financial impact of these projects, the process of determining and reporting ...
Assessment of the National Energy Efficiency Motor Programme
(North-West University (South Africa) , Potchefstroom Campus, 2015)
South Africa is currently facing an electricity demand challenge. In response to these
challenges, Eskom as the power utility has formed a division to manage the short-term
electricity supply and demand challenge. The ...
Expanding compressed air management through cross cut isolation
(North-West University (South Africa)., 2022)
Compressed air on deep-level mines is regarded as an important source of energy for underground mining operations, as the compressed air network forms the backbone of several mining processes over a 24-hour mining cycle. ...
Expanding compressed air demand side management through selective level control
(North-West University (South Africa)., 2022)
Compressed air is a resource which is used across the deep-level mining industry for a variety of
purposes throughout the 24-hour mining cycle. It has been noted that compressed air is a
particularly inefficient source ...
Optimising energy recovery on mine dewatering systems
(North-West University, 2018)
Mines in South Africa face many challenges. Chief among these are rising production costs. This coupled with labour unrests and investor uncertainty means that mines are under significant strain. An excellent method to ...
An integrated approach to optimise energy consumption of mine compressed air systems
(North-West University, 2012)
The demand for electricity in South Africa has grown faster than the increase in generation capacity. However, it is expensive and time consuming to commission new power stations. Another approach is to reduce electricity ...
Energy efficiency opportunities in mine compressed air systems
(North-West University, 2009)
Demand Side Management (DSM) is one of the most viable and sustainable short term methods to address the shortfall in electricity generation in South Africa. This is because DSM projects can be implemented relatively ...
