Unreliable and unsustainable electricity supply has been experienced in South Africa since 2007. Eskom implemented Demand Side Management (DSM) as a short-term solution to alleviate this problem. Several compressed-air ...

Electrical energy is commonly used in households and in industry - demand continues to rise due to economic and population growth. This requires that energy suppliers must increase their supply capacity. The result is that ...

The energy provider in South Africa, Eskom, faces an increasing electricity demand. The need to ensure sufficient supply gave rise to Demand Side Management (DSM) projects scheme. The DSM focus has shifted to the mining ...

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 ...

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 ...

The South African metals and mining industry is under pressure to increase their production output. While South Africa’s production trend has been decreasing, even though it is the third largest gold reserve, the global ...

Platinum mines are facing several challenges and a higher-than-inflation increase in electricity costs is amongst the most significant. Compressed air accounts for up to 38% of a platinum mine’s energy consumption. To ...

South Africa experienced a severe shortfall in electricity supply during 2008. Eskom, the national electricity supplier, implemented several strategies to alleviate the situation. The Power Conservation Programme set the ...

As the operational costs of deep-level mines increase and gold ore grades decrease, profitability in the South African gold mining sector is becoming a challenge. Electricity tariff increases moreover contribute to the ...

Compressed air on deep-level mines is regarded as an important source of energy for underground mining operations, as the compressed air network forms the backbone of several mining processes over a 24-hour mining cycle. ...
