What does "load shedding" mean in electrical systems?

Load shedding in electrical systems refers to the practice of reducing electrical demand during periods of high usage. This is often necessary to prevent overloading the power grid or to maintain the stability and reliability of the system. When demand exceeds supply, utilities may intentionally cut off electricity to certain consumers or sectors, ensuring that the overall demand remains within manageable limits. This helps to avoid potential blackouts and maintain the integrity of the electrical grid.

The context in which load shedding occurs typically involves scenarios where the generation capacity is not sufficient to meet the peak demand. By temporarily reducing the load, electrical systems can balance supply and demand, safeguarding against more severe consequences such as widespread outages.
