South Africa's energy crisis (or load shedding) is an ongoing period of widespread national power outages beginning at the end of 2007. [1] [2] The South African government-owned national power utility, and primary power generator, Eskom, and various parliamentarians have attributed these rolling blackouts to insufficient generation capacity.

A room during load shedding at night in West Bengal, India. A rolling blackout, also referred to as rota or rotational load shedding, rota disconnection, feeder rotation, or a rotating outage, is an intentionally engineered electrical power shutdown in which electricity delivery is stopped for non-overlapping periods of time over different parts of the distribution region.
This resulted in long running periods of level 4 load shedding across the country in mid-March 2019, including night-time load shedding [162] and promised to report back. [161] The situation at Eskom and resulting energy crisis became a political issue during the 2019 South African general elections .
Kriel Power Station in Mpumalanga, South Africa, is a coal-fired power plant operated by Eskom.It is located about 4 km from Matla Power Station just outside the town of Kriel (Emalahleni Local Municipality, Mpumalanga).
City Power currently obtains 90% of its power from Eskom and 10% from the Kelvin Power Station from which it seeks to move away from. [5] In 2014, it announced that it will remotely switch off geysers "to reduce the impact of load shedding. [6] In 2021, it resolved to be an electricity generator to "reduce over-reliance on Eskom".

Since electrical energy is a form of energy that cannot be effectively stored in bulk, it must be generated, distributed, and consumed immediately. When the load on a system approaches the maximum generating capacity, network operators must either find additional supplies of energy or find ways to curtail the load, hence load management.
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.
In 2020, Eskom began establishing independent boards and directors. On 17 December 2021, Eskom legally transferred its transmission division to the National Transmission Company of South Africa; [ 2 ] 374 transmission lines with a total length of 33 199 km, 500 three-phase transformers with a total capacity of 159 384 MVA located at 169 ...
