Relentless heat, stressed grid: What's behind Delhi-NCR's frequent power cuts?
Complaints about unscheduled blackouts, especially at night, have surged on social media, with many residents reporting hours without electricity during the intense heat.

As temperatures soar past 45°C in the national capital, former Delhi Chief Minister Arvind Kejriwal highlighted the distress of residents facing frequent power outages.
In a recent post on X, he wrote: “In this severe 45-degree heat, power cuts are happening across Delhi. Delhiites are in distress. Lights go off anytime.”
Although Kejriwal's message then pivoted to political digs at the current administration, the issue he brought up is real.
Complaints about unscheduled blackouts, especially at night, have surged on social media, with many residents reporting hours without electricity during the intense heat.
Power distribution companies like BSES are receiving numerous grievances, though officials maintain they are addressing them.
While residents across the Delhi-NCR are left wondering what's behind these frequent power cuts.
The issue does not seem as surprising with context.
Delhi-NCR is currently in the grip of a severe heatwave, with daytime temperatures hitting 42-45°C, well above normal. The India Meteorological Department (IMD) has issued alerts, warning of continued extreme conditions.
But what makes handling the heat particularly tough is the rise in nighttime temperatures. Minimum temperatures have stayed unusually high in recent weeks, often in the upper 20°C, sometimes even crossing 30°C.
This rise in nighttime temperatures is driven by the urban heat island effect and climate patterns. Concrete buildings, roads, and reduced green cover absorb heat during the day and release it slowly at night.
These constant high minimum temperatures worsen health risks, especially for the elderly, children, and outdoor workers, as the body gets less chance to cool down.
That's where the rise in energy demand comes in.
Weathering hot days and now warmer nights, too, means air conditioners, coolers and fans run longer, keeping electricity demand high around the clock.
ENERGY DEMANDS RISE WITH TEMPERATURES
Delhi’s power demand hit a 2026 high of 7,776 MW recently, driven largely by cooling needs.
On May 19, Tuesday, when Delhi faced a scorching 45.1C, the capital's electricity consumption climbed to 7,776 MW around 3:30 pm, the highest peak yet this year, according to the State Load Dispatch Centre.
The spike in power consumption was in line with what happened the day before, on May 18, when afternoon power demand rose to 7,542 MW and further climbed to 7,600 MW in the evening hours.
Air conditioners, coolers, and fans push consumption sharply during heatwaves and with this year’s peak arriving earlier than usual, trends are pointing to an energy-intensive summer ahead.
Therefore, when it comes to a rise in power cuts, the higher power demand from heat is a clear factor.
When millions switch on cooling appliances simultaneously, it strains the distribution network. Local issues like overloaded transformers or maintenance can then lead to outages, even if overall supply meets the demand.
Delhi’s power infrastructure has improved over the years with added capacity, but rapid urban growth and more extreme weather has also kept up with the growth, often testing its limits.
Climate change is making heatwaves more frequent and intense, increasing pressure on the grid nationwide.
MORE POWER CUTS SCHEDULED
And the spell of increased power cuts is not yet over.
On May 20, power companies BSES and Tata Power DDL announced planned shutdowns for maintenance, network upgrades, transformer changes, and other technical work.
These affect several parts of the city, including Hauz Khas, Janakpuri, Rohini, Shalimar Bagh, Narela, Model Town, and many others for a few hours each.
Officials have said that these planned interruptions are necessary to improve long-term reliability of the power networks.
However, on a day when temperatures in Delhi are expected to touch 46°C, the planned improvements are bound to add to the hardship for residents already sweating under the weight of a harsh, hot climate.
