Earlier, the government had said that it is planning to reduce office hours and introduce virtual office to save electricity.
The government had decided to halt production of all the diesel-run power plants -- which provide some 2.79% of the country's electricity -- currently in operation across the country until further notice. It also decided to keep fuel stations closed for a day every week in a bid to tackle the ongoing power and energy crisis.
