"Switching off the electricity at one time can reduce the electricity demand. If all lights are switched off at one time for nine minutes there is possibility of a grid collapse resulting in blackout in the entire country," Raut said.
"Due to the lockdown, there is a change in the demand and supply situation. If there is a sudden drop or increase in the demand or supply in the grid, there could be disturbance in the grid frequency," he said.
"Considering the possible situation, citizens and all the electricity generation, distribution and transmission companies should take required precautions," he added.
At present, the power demand in the state has come down from 23,000 MW to 13,000 MW, the minister said. Due to the lockdown, the industry load is zero. The 13,000 MW load is on essential services and residential, he said.
"If the electricity is switched off together, all power stations can go on high frequency and there is possibility of grid tripping. If all power stations are shut, there can be multi-state grid failure," the minister added.
