Explained: Here’s how power system will be managed during lights-out today

A 9-minute lights-out by most of households on Sunday evening can potentially collapse the grid due to sudden drop and then a quick surge after the event. But to manage the dramatic changes in electricity and its impact on the grid, the government has drawn an elaborate plan to manage it. Following are the broad plan of action.

Electrical appliances such as AC, fans, TVs, refrigerators are not supposed to be switched off and only household lights are to be switched off from 9 pm to 9.09 pm on Sunday.

Also, lights in all essential services, including hospitals, police stations and manufacturing facilities as well as street lights are not to be switched off.
