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.
The outage occurred only an hour after the National Electricity Market Management Company (NEMMCO) issued a statement saying load shedding was ending and power had been restored. Authorities say there had been a major electricity failure in the city's west, caused by the three-day heatwave.
On 7 December 2022, level 6 load shedding was reimposed when over 20,000MW of generation was taken off line due to a high number of power station breakdowns. [113] [114] It was reported that level 7 load shedding might begin if planned maintenance was implemented, that would take one of Koeberg's nuclear reactors offline. [115]

Power outages are categorized into three different phenomena, relating to the duration and effect of the outage: A transient fault is a loss of power typically caused by a fault on a power line, e.g. a short circuit or flashover. Power is automatically restored once the fault is cleared. A brownout is a drop in voltage in an electrical power ...
A power outage (also called a power cut, a power out, a power blackout, power failure or a blackout) is a loss of the electric power to a particular area. Power failures can be caused by faults at power stations, damage to electric transmission lines, substations or other parts of the distribution system, a short circuit , cascading failure ...
Peak demand, peak load or on-peak are terms used in energy demand management describing a period in which electrical power is expected to be provided for a sustained period at a significantly higher than average supply level. Peak demand fluctuations may occur on daily, monthly, seasonal and yearly cycles.
