Delhi has been hit by a crippling 45C heatwave which has sent power demand to record highs.
Temperatures have felt as high as 49.2C in the Indian capital, which has been trapped in a heatwave for weeks.
The city has experienced regular power outages as people try to stay cool using items such as ACs, sending power demand to a record high of 8,647 megawatts (MW) on Tuesday, according to the BBC.
The capital's record came after northern India saw peak power consumption at 89,000 MW on Monday.
The India Meteorological Department (IMD) has predicted above-normal temperatures for June in the northwest and central parts of the country, making it one of the longest heatwave spells.
Government data shows that there were nearly 25,000 cases of suspected heat stroke and 56 people lost their lives in the sweltering heat across the country from March to May.
India's power ministry said demand for power at the peak time on Monday reached 89,000 MW, the highest ever for the northern region, adding that the strong demand, which has prevailed since May 17, was "challenging".
The temperature in the national capital Delhi was about 44C late on Monday afternoon but the IMD said it felt like 49.2C.
In Delhi, which is facing a water shortage, the highest daily temperatures have stayed above 40C since May 12 and are forecast to fall below that mark only on June 26.
The ministry said it was able to supply power to the northern parts by importing 25 to 30 per cent from neighbouring regions and urging all utilities to minimise forced outages of equipment.
This summer has seen a record peak 250GW demand for power throughout the country, with the ministry implementing various measures as the need for air conditioners and other cooling appliances rises.
The IMD expects some respite from the heat from Thursday although the monsoon has delivered a fifth less rain than normal so far this season.
Sweltering heat and policy measures have fuelled a surge in the use of gas-fired power, with power generation doubling in April and May to 8.9 billion kilowatt-hours (kWh) compared with the same period last year, according to data from Grid India.
