The development of a methodology to measure & verify the impact of a national solar water heating program
(North-West University, 2010)
The School for Mechanical Engineering at the North-West University is home to one of South Africa's most established Measurement & Verification (M&V) teams. The team is involved with South Africa's electricity utility, ...
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 ...
The adaptive predictive control of an energy efficient central water heating system applied in the South African commercial sector
(North-West University (South Africa), Potchefstroom Campus, 2016)
Since the introduction of load shedding in the latter part of 2007, Eskom, the electrical
utility of South Africa, have been forced to implement energy efficient and energy management
measures to ensure the stability of ...
Integration of DSM interventions into bulk water supply strategies
(North-West University (South Africa) , Potchefstroom Campus, 2015)
Supplying water to communities, industries and agricultural developments within South Africa is a cardinal task undertaken by the Department of Water Affairs (DWA). South Africa is a water-scarce country with an uneven ...
Challenges faced during implementation of a compressed air energy savings project on a gold mine
(2014)
Demand side management (DSM) initiatives have been introduced by Eskom to reduce the deficit between the electricity generation capacity and the electricity usage within the country. DSM projects enable Eskom to reduce ...
Improving efficiency of a mine compressed air system
(North-West University (South Africa) , Potchefstroom Campus, 2017)
Eskom supplies electricity to South Africa, which experienced a capacity margin shortfall. Energy savings
companies (ESCOs) implement demand side management (DSM) initiatives to reduce the power strain
on the electricity ...
Reducing electrical costs for a mine ventilation system with the aid of simulation software
(North-West University (South Africa) , Potchefstroom Campus, 2017)
Eskom, the South African state owned power utility, offers a demand side management (DSM) program that suggests different electrical energy tariffs during different times of the day for large consumers of electrical energy, ...
Reconfiguring mining compressed air networks for cost savings
(2014)
The world is currently experiencing major issues in the energy sector. The ever-growing human population, limited energy resources and the effect of greenhouse gas emissions have become major global concerns for the energy ...
The cost-effectiveness of comprehensive system control on a mine compressed air network
(2014)
Compressed air leakage accounts for up to 42% of electrical energy loss on a typical mine compressed air system. By using underground control valves it is possible to reduce the amount of air leakage. Underground valve ...
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 ...
