Eskom represents South Africa in the Southern African Power Pool. The utility is the largest producer of electricity in Africa, [19] [20] is among the top seven utilities in the world in terms of generation capacity and among the top nine in terms of sales. It is the largest of South Africa's state owned enterprises.
Electric power distribution is the final stage in the delivery of electricity. Electricity is carried from the transmission system to individual consumers. Distribution substations connect to the transmission system and lower the transmission voltage to medium voltage ranging between 2 kV and 33 kV with the use of transformers . [ 1 ]
South Africa has a large energy sector, being the largest economy in Africa. The country consumed 227 TWh of electricity in 2018. [1] The vast majority of South Africa's electricity was produced from coal, with the fuel responsible for 88% of production in 2017. [2] South Africa is the 7th largest coal producer in the world.

This diagram depicts the electrical structure [22] of the network, rather than its physical geography. Electric power transmission is the bulk movement of electrical energy from a generating site, via a web of interconnected lines, to an electrical substation, from which is connected to the distribution system. This networked system of ...
Three-phase electric power (abbreviated 3ϕ [1]) is a common type of alternating current (AC) used in electricity generation, transmission, and distribution. [2] It is a type of polyphase system employing three wires (or four including an optional neutral return wire) and is the most common method used by electrical grids worldwide to transfer ...
Around 81% of South Africa's energy needs are directly derived from coal [9] and 81% of all coal consumed domestically goes towards electricity production. [10] 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.
Mains electricity by country includes a list of countries and territories, with the plugs, voltages and frequencies they commonly use for providing electrical power to low voltage appliances, equipment, and lighting typically found in homes and offices. (For industrial machinery, see industrial and multiphase power plugs and sockets.) Some ...
Conventional 2-wire or 3-wire distribution lines have a higher power transfer capacity, but can require 7 poles per kilometre (12 poles per mile), with spans of 100 to 150 metres (110 to 160 yards). SWER's high line voltage and low current also permits the use of low-cost galvanized steel wire (historically, No. 8 fence wire). [ 9 ]
