MBA, North-West University, Potchefstroom Campus, 2018 Water resources in South Africa comprise the following three sources in the order of magnitude: surface water (77%), dams and rivers return flows (14%), rain and groundwater. There is 98% assurance level which suggests that any peaks in future demand will result in demand exceeding supply and this is a source of vulnerability that needs to be addressed. The fact that only three coal-fired power stations are within the water usage targets provides the reason for investigating the problem. Eskom is under pressure to utilise the 2-3% of South African water which is allocated to them for power generation wisely and effectively. During these times of water constraints, it is important that the power stations are operational without violating their water use license agreements. The South African Electricity Supply Industry (ESI) remains dominated by the state-owned and vertically integrated utility provider Eskom. It ranks seventh in the world regarding size and electricity sales. It generates about 95% of South Africa's electricity and another 40% for the African continent. Eskom owns and controls the high voltage transmission grid and supplies about 60% of its electricity directly to customers. The remainder of the electricity distribution is undertaken by 177 local authorities that buy bulk-supplies of electricity from Eskom, while some also municipalities do generate small amounts of electricity themselves which they sell in their areas of jurisdiction. Eskom has 28 power stations of which 14 are large coal-fired stations. The majority of coal-fired power stations are situated near the coal mines in the North-East of the country. All the coalfired power stations are dependent on two main raw material inputs to function; this is coal and water. Authorisation to use water is dependent on a water licence, and each of the power stations has a water use licence. The water use licence is a binding document which outlines the maximum amount of water which the power station can extract from the water source. Masters |
