Comparison between automated and manual DSM pumping projects
(North-West University, 2008)
The purpose of this dissertation is to identify the best alternative method of load shifting on clear water pumping systems in the mining industry. This can be done through a comparison analysis between manual and automated ...
Reconfiguring mine water reticulation systems for cost savings
(North-West University, Potchefstroom Campus, 2018)
Rising electricity costs in South Africa force companies, including gold mines, to minimise their
energy consumption (EC). More than 30% of the total energy demand for deep-level mines is
consumed by the water reticulation ...
Research into real-time energy management on old gold mines
(North-West University, 2006)
The South African Electricity Supply Industry is one of the backbone industries in South
Africa. During 2003, it became clear that the demand for electricity in South Africa was
increasing at a rate that had not been ...
Effects of load shifting on water quality in a large potable water network
(2015)
Mathematical analyses indicated that significant possibilities exist for load shifting projects on a Large Potable Water Utility (LPWU) in South Africa. A primary concern remained, i.e. whether the load variation would ...
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 ...
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 ...
Reducing energy consumption of a deep-level platinum mine dewatering system through infrastructure reconfiguration
(North-West University (South Africa)., 2022)
South Africa is the largest producer of platinum in the world, accounting for up to 80% of global production. The mining sector contributes significantly to the South African economy, but this contribution is hindered by ...
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 ...
Strategies to revive DSM mine pumping projects under the new ESCo model
(North-West University (South Africa) , Potchefstroom Campus, 2017)
South Africa has a highly energy intensive economy dependent on a generation fleet of mostly ageing coal-fired power stations struggling to keep up with demand. The mining industry, and specifically mine pumping systems, ...
Quantifying the effects of system constraints on the electricity cost of dewatering pumps
(North-West University (South Africa) , Potchefstroom Campus, 2016)
Eskom embarked on a capacity expansion programme in 2005. The capacity expansion programme is being funded by above-inflation electricity tariff increases, which put large electricity consumers such as mines under financial ...
