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 ...
A variable water flow strategy for energy savings in large cooling systems
(North-West University, 2013)
Large cooling systems consume up to 25% of the total electricity used on deep level mines. These systems are integrated with the water reticulation system to provide chilled service water and cool ventilation air. Improving ...
Implementing DSM interventions on water reticulation systems of marginal deep level mines
(2014)
Because of a continuous increase in the demand for electricity in South Africa the country’s largest electricity utility (Eskom) has been under strain to provide electricity. An expansion programme to generate more electricity ...
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 ...
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 ...
Optimising the operation of underground mine refrigeration plants and ventilation fans for minimum electricity cost
(North-West University, 2003)
This study describes the development and use of a mathematical model that will enable mine operators to
minimise the costs of electricity consumed by the ventilation and refrigeration systems used for
environmental control ...
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 ...
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 ...
Structuring data to capture energy reticulation knowledge
(North-West University (South Africa), 2020)
Energy management is essential due to the increase in energy costs and its effects on the environmental footprint of an industrial site. Managing energy is an essential but complicated task. This complexity derives itself ...
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 ...
