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 ...
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 ...
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 ...
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 ...
Tariff structure selection for optimal electricity cost savings on a process plant
(North-West University (South Africa), Potchefstroom Campus, 2016)
South Africa's electricity grid is currently under strain due to the high demand of electricity.
This strain on the grid has resulted in the increase of electricity costs that has put financial
pressure on consumers. In ...
