LOAD SHED Meaning and
Definition
-
Load shedding refers to the controlled and intentional reduction of the electrical load in a power supply system. It is a temporary measure implemented by power utilities or grid operators to manage electricity demand on the system during times of scarcity or deficit. When the demand for electricity exceeds the available supply, load shedding is initiated to prevent an imbalance that could lead to a total blackout or system failure.
During load shedding, specific areas or regions are identified, and the electricity supply to those areas is deliberately curtailed or turned off for a specific period. This helps to rebalance the supply and demand equation, ensuring that the power system remains stable and avoids collapsing under excessive load.
Load shedding is typically implemented according to predetermined schedules, which are communicated to the public in advance to allow for preparation and time management. The duration and frequency of load shedding can vary depending on the severity of the power shortage and the capacity of the power grid.
Load shedding can have several implications and consequences, such as disruptions in daily activities, inconvenience to businesses and households, and economic losses. However, it is deemed as a necessary measure to prevent overloading and protect the power infrastructure from damage, which could take longer to repair and restore compared to the controlled temporary power outages imposed during load shedding.
Etymology of LOAD SHED
The term "load shed" is composed of two words: "load" and "shed".
- "Load" refers to the amount of electrical power consumed by devices or appliances that are connected to a power grid. It can also refer to the total power demand on an electrical system or the burden it puts on the system.
- "Shed" in this context means to discard or reduce. In the electrical context, it means to intentionally reduce the demand or load on the power grid by regulating or interrupting the supply of electricity to certain areas or consumers.
Therefore, "load shed" originated as a technical term used in the electrical engineering field to describe the controlled reduction of electricity demand when the supply is insufficient or during periods of peak demand. It is commonly used to manage and balance the electrical load on a grid, preventing disruption or overload.
