Advantages: SA has abundant coal reserves. Coal-fired power stations are reliable. South Africa’s infrastructure to generate electricity from coal is well established.
Where can coal fired power stations be found in South Africa?
South Africa has rich coal deposits concentrated in the north-east of the country and as such the majority of South Africa’s coal-fired plants are located in the Mpumalanga province.
What type of coal does Eskom use?
South African power stations generally use low-grade coal for steam production. Eskom has succeeded at many of its power stations, specifically at Lethabo, to use coal which is of a very low grade, a Calorific Value of 15-16Mj/kg also with a very high ash content, ±42%.
What is the name of the largest coal fired power station in South Africa?
Kusile power station, which is expected to become the world’s largest coal-fired power plant upon completion, is being constructed in Mpumalanga, South Africa.
What are the disadvantages of South Africa’s reliance on coal as the main source of energy in power stations?
The main disadvantages are: The use of coal is not sustainable as coal is a non-renewable energy source. The use of coal has serious negative environmental impacts.
Which country is supplying South Africa with electricity?
South Africa exports electricity to seven countries in Southern Africa. On the list, we have Zimbabwe, Lesotho, eSwatini, Namibia, Botswana. Mozambique and Zambia. Wilkinson says that Zimbabwe is not only importing electricity from South Africa but from the Democratic Republic of Congo and Mozambique.
What is the main use of coal in South Africa?
South Africa’s indigenous energy resource base is dominated by coal. Internationally, coal is the most widely used primary fuel, accounting for about 36 percent of the total fuel consumption of the world’s electricity production. About 77 percent of South Africa’s primary energy needs are provided by coal.
Is there unlimited supply of coal in South Africa?
The country has vast coal reserves extracted by cheap open-cast mining. The almost unlimited supply of this fuel source encouraged the development of many large coal power plants, especially in the 1970s and 1980s. By 2010, 90% of South Africa’s electricity was generated from coal.
What are the advantages and disadvantages of coal power stations?
Energy produced from coal fired plants is cheaper and more affordable than other energy sources. Since coal is abundant, it is definitely cheap to produce power using this fuel. Moreover, it is not expensive to extract and mine from coal deposits.
What are the grades of coal?
Coal is classified into four main types, or ranks: anthracite, bituminous, subbituminous, and lignite.
How old is Medupi power?
Medupi is a dry-cooled coal-fired power station under construction in Lephalale, South Africa. Formerly known as Project Alpha and Charlie, the plant’s construction began in August 2007. It is being developed by Eskom, South Africa’s state-owned power corporation, at an estimated cost of R122.5bn.
How old is Kendal power?
Kendal power station is located 40 km west of Witbank in Mpumalanga. Construction started in July 1982 and the last of its six 686 MW units went into full operation in 1983.
What does Eskom stand for?
Eskom is a South African electricity public utility, established in 1923 as the Electricity Supply Commission (ESCOM) and also known by its Afrikaans name Elektrisiteitsvoorsieningskommissie (EVKOM), by the South African Government and people of the Republic of South Africa in terms of the Electricity Act (1922).
Why coal mining is so important for South Africa?
Coal as a source of energy
Coal is South Africa’s dominant energy source. 77% of South Africa’s energy needs are provided by coal, according to the Department of Energy6. Eskom produces 95% of electricity used in South Africa7, and its coal-fired stations produce about 90% of electricity produced by the utility8.
How much is South Africa’s reliance on coal?
In 2020, 86% of South Africa’s electricity came from coal, compared to the global average of 34%. It is significantly ahead of the next highest G20 member, India, which generates 71% of its electricity from coal.
Why are we using coal?
Coal is used primarily in the United States to generate electricity. In fact, it is burned in power plants to produce more than half of the electricity we use. A stove uses about half a ton of coal a year. A water heater uses about two tons of coal a year.
