Coal in South Africa

Coal in South Africa

South Africa produces in excess of 260 million tonnes of coal (2003 estimate) and consumes almost three quarters of that domestically.[1] Around 77% of South Africa's energy needs are directly derived from coal[2] and 92% of coal consumed on the African continent is produced in South Africa.[3]

The use of coal in South Africa dates back to 300 AD when coal furnaces were used to melt iron and copper, but large-scale exploitation did not occur until the mid-19th century.[4]

Coal reserves in BTUs as of 2009

The largest coal deposits in South Africa are to be found in the Ecca Group, a stratum of the Karoo Supergroup, dating from between 280 and 250 Ma. The Ecca Group is extensive, covering around two thirds of South Africa and contains more than a third of all coal reserves in the Southern Hemisphere.[6][5]

Notable coalfields are:

  • Waterberg Coalfield[7]
  • Highveld Coalfield[7]
  • Witbank Coalfield[7]
  • Ermelo Coalfield[7]
  • Utrecht Coalfield[7]
  • Klip River Coalfield[7]

Economic impact

South Africa is one of the seven largest coal-producing[5][8] and one of the top five coal-exporting[2] countries in the world.

More than a quarter of coal mined in South Africa is exported, most of which leaves the country via Richards Bay.[2] Coal is South Africa's third largest source of foreign exchange; platinum being the largest and gold second.[9] Around 15% of the country's GDP (2000 estimate) is spent on energy[9] and 77% of that is derived from coal.[2]

In 2004, the coal and lignite mining industry generated a gross income of R39 billion and directly employed 50,000 people.[10]

The Witbank Coalfield accounts for 40% of South Africa's coal production.[11]


The five largest coal mining companies account for around 85% of all production. They are Anglo American Thermal Coal, BHP Billiton's Ingwe Collieries, Sasol Mining, Eyesizwe and Kumba Resources.[2]

Open-pit mining account for roughly half of South African coal mining operations, the other half being sub-surface.[2]

Coal consumption

Electricity generation

Electricity generation accounts for 43% of all coal consumed in South Africa (1997 estimate).[9]

Many of the country's coal-fired power station are located in close proximity to a coal mine and are supplied with fuel directly from the mine. The Grootegeluk open cast mine on the Waterberg Coalfield in Limpopo is one of the largest in the country and feeds the Matimba Power Station[12] with about 14.6 million tons of coal a year[13] via a conveyor system.[14] The mine is also contracted to supply the new Medupi Power Station.[13]

Liquid fuel

Around 35% of liquid fuel used in South Africa is derived from coal mined by Sasol Mining at the Secunda CTL plants.[15][3][16]

Household use

In 1995 around a million lower-income households in South Africa depended on coal as their primary energy source for cooking, lighting and heating.[17] This number has been decreasing steadily during the first decade of the 21st century due to the expansion of electricity supply to lower-income households and rural regions.[18]

Environmental impact

Environmentalists in South Africa and abroad have criticized the decision of the World Bank's approval for a $3.75 billion loan to build the world’s 4th largest coal-fired power in South Africa. The plant will increase the demand for coal mining and production. Protesters are urging the bank to stop supporting the development of coal plants and other large emitters of greenhouse gas and polluting operations from coal mining. [19]

Usage of coal and liquid fuel derived from coal accounts for around 86% of the 113 million tons of carbon dioxide emissions South Africa produces annually (2006 estimate)[20] and represents around 40% of Africa's total coal derived CO2 emissions.[21]

The largest contributor to coal-derived air pollution is household coal usage (65%), followed by industry (30%) and electricity generation (5%).[22]

Some coal mines have been abandoned by their owners, mainly due to companies ceasing to exist. Many of these mines, such as the Transvaal and Delagoa Bay Collieries (T&DB) outside Witbank, have not been rehabilitated prior to being abandoned and are a major source of water and air pollution. It is estimated that clean-up and rehabilitation of the T&DB Collieries will cost around R100 million.[23] Coal seam fires were common, but controlled, at T&DB Collieries during the mines operation, but the fires have been left to burn out of control since the mine was closed in 1953, to the extend that in 1995 flames could be seen above ground.[24]
