People in certain localities of West Delhi even hit the street protesting long power cuts.
The VVIP areas in central Delhi also went without power for more than four hours which affected functioning of offices.
Chief Minister Sheila Dikshit said the power demand in various northern states have gone up significantly and the situation was not going to improve till monsoon arrives in the city.
"Yes, naturally it (load shedding) is happening on a large scale...The demand in the northern states have gone up. The problem will remain till monsoon arrives," Dikshit said, exhorting people to limit consumption of power.
Angry over long outages, people in West Delhi came out to the street protesting the power cuts.
"There was no power in our area for six hours. Because of power cuts we could not even fill our water tanks. So imagine the situation," said a protester in Uttam Nagar area.
The maximum power demand was recorded today at 5350 mega watt against yesterday's 5454 mega watt, which was the highest ever power demand in Delhi.
Officials said production of power at the Badarpur Thermal Power Station came down to 510 MW from 633 MW due to shortage of water.
Most of the areas in the city faced power cuts due to technical faults as the distribution networks tripped due to increasing load on them.
"The distribution companies have not been able to invest on the infrastructure due to which when the load on the distribution networks increases, they trip," said a senior power department official.
He said as power tariff has been increased by 26 per cent, now the discoms should be able to invest on their infrastructure.
