Supply of power was affected immediately after rain and thunderstorm in the evening and areas in South, North and East Delhi were mainly hit.
"There was over four hour long power cut in our area. Power was disrupted immediately after the onset of thunderstorm around 4 PM and resumed after around 7 PM," said a resident of the Nizamuddin area.
A power department official said the outages were reported primarily due to local faults.
"The outages took place not because of shortage of power but due to local faults," said the official.
