## Summary

[India](/ko/entity/india-grid)'s peak power demand hit a record 270.82GW at 15:45 on 22 May 2026 as
New Delhi reached 45.3°C, beating an earlier 256GW record on 25 April. Peak demand has
roughly doubled since 2013 (~135GW). [Air-conditioning](/ko/entity/electricity) now adds an estimated
60-70GW to peak load, and night demand reached 251.96GW on 21 May, meaning the grid no
longer cools off after dark. [Thermal](/ko/entity/coal) supplied 62% of generation at peak; domestic
coal demand for power is projected at 233 million tonnes in April-June, up 11.5% year on
year. With thin [battery storage](/ko/n/china-battery-storage-surge-2026), operators run coal to
its flexibility ceiling and burn costly gas to cover evening solar ramp-downs.

## By the numbers

- 270.82 GW, record peak, 22 May 2026 (prior record 256GW, 25 April).
- 45.3°C, New Delhi temperature at the peak.
- 60-70 GW, estimated air-conditioning contribution to peak.
- 251.96 GW, night peak (21 May), daytime/nighttime gap closing.
- 233 Mt, projected Q2-2026 coal demand for power, +11.5% YoY.

## Why it matters

India's load curve is being reshaped by heat and cooling faster than its storage and
flexible generation can follow. The dependence on coal to chase the evening ramp locks in
emissions and exposes the grid to fuel and ramping stress in every successive heatwave.

## What to watch

- Whether IMD's above-normal June forecast triggers fresh records or load-shedding.
- Battery-storage and pumped-hydro additions targeting the evening peak.
- Coal stock levels at thermal plants through the monsoon transition.

### Indian environment policy
- **Down To Earth** (India, en) — Decodes the record peak as a dispatch problem: solar covers the day but coal and costly gas plug the evening cooling ramp, since storage and flexible capacity remain thin. Treats coal flexibility as the binding constraint.

### Indian market
- **Outlook Business** (India, en) — Frames extreme heat as structurally rewiring demand: air-conditioning adds 60-70GW and night peaks now rival daytime, ending the assumption that solar alone can chase the load curve.
  > "Air-conditioners now contribute 60-70GW to peak load; evening and night demand also set records."
