"Contrary to popular perception that higher day temperatures require more power consumption, Delhi's power demand is increasingly peaking during the night hours mainly because of cooling load," a discom official said.
Delhi's peak power demand has increased by over 250 per cent since 2002, when it was 2,879 MW.
It clocked an all-time high of 7,409 MW on July 2 this year, according to the data.
"Cooling load is the main factor behind the increase in Delhi's power load. In fact, according to estimates, almost around 50 per cent of Delhi's power demand in summers is because of the cooling load of ACs, coolers and fans," the official said.
Air conditioning can account for up to 30-50 per cent of annual energy cost of a company or households.
During summers, Delhi's power demand peaked during night on 89 days - 19 in May, 18 in June, 24 in July and 28 days in August, the data shows.
In fact, even on July 2, when Delhi's demand clocked an all-time high of 7,409 MW, power demand in South and West Delhi first made an all-time high record on 3,159 MW in the afternoon only to again breach it during the night (3,189 MW), discom officials said.
