In this study a new tool was developed that made new approaches possible for the successful
implementation of Demand Side Management (DSM) projects. The new approaches are
incorporated into a generic tool that makes it possible for Energy Services Companies (ESCos) to undertake DSM projects that were previously not possible with currently available technology.
Through these new approaches, maximum results can be obtained on a sustainable basis on the
clear water pumping systems of South African mines.
The author was responsible and participated in four different investigations and implementations of
DSM projects. These were grouped into three case studies. Each of these studies required different
new innovations.
The innovations described in this thesis include the adaptation of the Real-time Energy
Management System (REMS) that was developed and marketed by HVAC International, to mines
with intricate pumping systems, mines without any instrumentation and control infrastructure, as
well as to mines that make use of a Three Pipe Water Pumping System.
The tool developed and applied in these projects was part of Eskom's DSM programme. In this
programme, large electricity clients who wish to shift electrical load out of peak periods, are
assisted by having the total costs of such projects funded by Eskom. The fact that the clients will
most likely enjoy substantial electricity cost savings, (by not having to pay the high peak prices), is
a major attraction of this programme. Nevertheless, the programme is not moving as fast as it
should.
The National Energy Regulator (NER) has set an annual target of 153 MW load to be shifted since
2003. By the end of 2005, the accumulated target load to be shifted will be 459 MW. However,
Eskom has indicated that an accumulated total of only 181 MW load will have been shifted by the
end of 2005. This means that the Eskom DSM programme has actually only achieved 39% of its
target.
The innovations described in this thesis will help ESCos to address this shortfall more effectively / Thesis (Ph.D. (Mechanical Engineering))--North-West University, Potchefstroom Campus, 2006
