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 ... -
Demand side management intervention on a large scale canal pumping scheme
(North-West University (South Africa) , Potchefstroom Campus, 2015)South Africa is the thirtieth driest country in the world and is classified as a semi-arid area. The annual rainfall differs from less than 200 mm at the west coast to more than 1000 mm on the east coast. The primary use ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ...
