South Africa produces around 240,300 gigawatt-hours (865,000 TJ) electricity annually.2007 est. Most of this electricity is consumed domestically, but around 12,000 gigawatt-hours are annually exported to Swaziland, Botswana, Mozambique, Lesotho, Namibia, Zambia, Zimbabwe and other Southern African Development Community countries participating in the Southern African Power Pool. South Africa supplements its electricity supply by importing around 9,000 GWh per year from the Cahora Bassa hydroelectric generation station in Mozambique via the 1,920 MW Cahora Bassa high-voltage direct current transmission system of which 1500 MW is sold to South Africa.
Most power stations in South Africa are owned and operated by Eskom. These plants account for 95% of all the electricity produced in South Africa and 45% of all electricity produced on the African continent.
In terms of share of GDP in 2012, South Africa was the 4th largest investor in renewable power in the world after Uruguay, Mauritius and Costa Rica.
The following is a list of electricity generating facilities within South Africa that are larger than 2 MW capacity. It contains currently operational facilities and facilities under construction. As far as possible the net power output in megawatts is listed, i.e. the maximum power the power station can deliver to the grid.

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. Around 77% of South Africa's energy needs are directly derived from coal and 81% of all coal consumed domestically goes towards electricity production. Historically this has given South Africa access to cheap electricity, but it is also one of the leading reasons that the country is in the top 20 list of carbon dioxide emitting countries.
