Energy efficiency through variable speed drive control on a cascading mine cooling system
An ever-expanding global industry focuses attention on energy supply and use. Cost-effective electrical energy production and reduced consumption pave the way for this expansion. Eskom’s demand-side management (DSM) ...
Modernising underground compressed air DSM projects to reduce operating costs
Growing demand for electricity forces suppliers to expand their generation capacity. Financing these expansion programmes results in electricity cost increases above inflation rates. By reducing electricity consumption, ...
An integrated energy efficiency strategy for deep mine ventilation and refrigeration
South Africa’s electricity supply is under pressure. Mining is one of South Africa’s largest electricity consumers with electricity-intensive services such as compressed air, cooling, ventilation, etc. More than 40% of ...
An integrated approach to optimise energy consumption of mine compressed air systems
(North-West University, 2012)
The demand for electricity in South Africa has grown faster than the increase in generation capacity. However, it is expensive and time consuming to commission new power stations. Another approach is to reduce electricity ...
