Hours of load shedding in South Africa by stage 2014–2023. Since 2007, South Africa has experienced multiple periods of loadshedding as the country's demand for electricity exceeded its ability, notably Eskom's ability, to supply it. During these periods the power is rationed between different electrical grid areas cross the country and ...
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.
In 2023, in an affidavit by outgoing Eskom CEO, André De Ruyter said former Eskom CEOs Brian Molefe and Matshela Koko refused to conclude agreements with Renewable Energy Independent Power Producers, thus exacerbating load shedding. It was estimated that up to 96% of load shedding would have been avoided had they not halted the REIPPPP. [9]
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".

In January 2008, Eskom controversially introduced load shedding nationally (rolling blackouts) based on a rotating schedule, in periods where short supply threatened the integrity of the grid. Demand-side management has focused on encouraging consumers to conserve power during peak periods in order to reduce the incidence of load shedding.
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.
The minister of electricity and energy is the energy minister in the Cabinet of South Africa. The office in its current form was established in June 2024 in a merger between the minister in the presidency for electricity and the energy functions of the minister of mineral resources and energy.
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.
