switch off all lights may cause failure of equipments

Thinking...PSPCL
Our Hon'ble PM has announced to switch off all lights of our houses at 9PM on 5th night for about 9 minutes. It may have immense impact on GRID due to huge reactive power generation. Even it may cause failure of equipments if adequate measures are not taken. In an integrated Grid our generation & pooling sub station equipments may face sharp over voltage. It may then take upto 48 hrs to restore the Grid. Hence Requested to all turn on geysers for 10 mins at 8.59 pm to save our country's national Power grid.🙏
If it happens 2 days minimum lights off in our houses
