The national power grid was prepared to handle the dip as a result of which thermal power plants were gradually scaled down prior to the expected time of dip in power demand. When at the scheduled time, the power demand started dipping, the power generation from hydel power plants were scaled to half of their power generating capacities. And after a short time when the power demand started surging, the power generation from hydel were rapidly increased to maintain grid balance, while that of thermal power plants were gradually increased.
