Sustaining compressed air DSM project savings using an air leakage management system
(North-West University, 2010)
Unreliable and unsustainable electricity supply has been experienced in South Africa since
2007. Eskom implemented Demand Side Management (DSM) as a short-term solution to
alleviate this problem. Several compressed-air ...
DSM strategy for national water pumping systems
(North-West University, 2012)
The continual increase in electrical energy demand in South Africa has resulted in a precariously low reserve margin in supply from the primary utility, Eskom. This resulted in extensive load shedding throughout the country. ...
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 ...
Sustained energy performance on compressed air systems for expanding gold mines
(2013)
The energy provider in South Africa, Eskom, faces an increasing electricity demand. The need to ensure sufficient supply gave rise to Demand Side Management (DSM) projects scheme. The DSM focus has shifted to the mining ...
Automated control of mine dewatering pumps
(2014)
Deep gold mines use a vast amount of water for various purposes. After use, the water is pumped back to the surface. This process is energy intensive. The control is traditionally done with manual interventions. The purpose ...
Integration of electricity cost saving interventions on a water distribution utility
(2014)
Electrical energy has become a very important and integrated part of the current era. Electricity cost saving interventions, such as load shifting, form part of demand side management (DSM) interventions. DSM interventions ...
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 ...
Reducing energy consumption on RSA mines through optimised compressor control
(North-West University, 2010)
South Africa experienced a severe shortfall in electricity supply during 2008. Eskom, the national electricity supplier, implemented several strategies to alleviate the situation. The Power Conservation Programme set the ...
Improved control of clear water underground pumping system for demand side management at an interconnected South African goldmine
(North-West University (South Africa) , Potchefstroom Campus, 2016)
Deep level clear water pumping at gold mines accounts for nearly 30 % of a mine’s total electricity consumption. Demand side management (DSM) initiatives for various deep level water pumping systems have been implemented ...
Optimising gold ore transportation systems for electricity cost savings
(North-West University (South Africa) , Potchefstroom Campus, 2015)
Electricity is an essential but limited resource in South Africa. Limited supply capacity and
growing demand cause electricity prices to increase rapidly, therefore, reducing electricity
consumption. Costs are critical ...
