With a few exceptions in deep rural areas, electricity is available almost everywhere in South Africa.

With the growth of the population, business and industry, supply is sometimes under pressure, particularly in densely populated urban areas when usage reaches a peak, such as on winter evenings, resulting in a power outage.

The supplier of South African electrictiy, Eskom, and government, have prioritised the extension of the South African electrical grid with the construction of new power stations, Diversification of poweer sources and instituting energy efficient programmes.

Tourists to South Africa should be aware that:

- The South African electricity supply is 220/230 volts AC 50 HZ.
- Most plugs are 15 amp 3-prong or 5 amp 2-prong, with round pins. If an adaptor is called for, consider bringing one with you, although they can be purchased locally.
- US-made appliances may need a transformer.
- Most hotel rooms have 110 volt outlets for electric shavers and appliances.
