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 is a list of notable wide-scale power outages. To be included, the power outage must conform to all of the following criteria: The outage must not be planned by the service provider. The outage must affect at least 1,000 people. The outage must last at least one hour. There must be at least 1,000,000 person-hours of disruption. For example:
Loss of load in an electrical grid is a term used to describe the situation when the available generation capacity is less than the system load. [1] Multiple probabilistic reliability indices for the generation systems are using loss of load in their definitions, with the more popular [2] being Loss of Load Probability (LOLP) that characterizes a probability of a loss of load occurring within ...
The per capita data for many countries may be slightly inaccurate as population data may not be for the same year as the consumption data. Population data were obtained mainly from the IMF [3] in 2021 with some exceptions, in which case they were obtained from the Wikipedia pages for the corresponding countries/territories.
Capacity factor is a measure of the output of a power plant compared to the maximum output it could produce. Capacity factor is often defined as the ratio of average load to capacity or the ratio of average load to peak load in a period of time. A higher load factor is advantageous because a power plant may be less efficient at low load factors ...
In a power outage, the microgrid controller disconnects the local circuit from the grid on a dedicated switch and forces any online distributed generators to power the local load. [ 3 ] [ 4 ] Unintentional islanding is a dangerous condition that may induce severe stress on the generator, as the generator must match any changes in electrical ...
The 2009–2011 load shedding period began when John Dramani Mahama was in government as Vice President. After the death of then President John Evans Atta Mills during when the persistent on and off nature of the power supply in the country became abhorrent, Ghanaians out of frustration named the situation dumsor .
