Analysis of Severe Heatwaves and Rising Electricity Demand Across India

Apr 26, 2026, 21:36

Introduction

A severe heatwave is currently affecting several Indian states. Temperatures are much higher than normal for this season, which has led to a record-breaking increase in the country's demand for electricity.

Main Body

Weather data shows that northern and central regions are facing extreme heat. For example, temperatures reached 47.4 degrees Celsius in Banda, Uttar Pradesh, and 46.4 degrees in Jaisalmer, Rajasthan. Similarly, Punjab and Haryana have consistently seen temperatures above 40 degrees Celsius. In the south, Tamil Nadu and Kerala are reporting high heat and humidity, leading the India Meteorological Department (IMD) to issue yellow alerts. Meanwhile, western Odisha recorded 44.8 degrees Celsius, although coastal areas remained cooler due to moisture from the Bay of Bengal. These weather conditions have caused significant disruptions to daily life. In Ayodhya, the number of daily visitors to the Ram temple dropped from over 100,000 to fewer than 40,000. Furthermore, authorities closed schools in Dehradun and postponed official meetings in Odisha. In Delhi, Chief Minister Rekha Gupta emphasized the need for safety by installing misting systems and providing rehydration salts for students, while ensuring that essential services have a constant power supply. This heat has led to an unprecedented surge in energy use. Peak power demand hit a new record of 256.11 GW on Saturday, surpassing the previous high from April 24. Experts attribute this increase to the widespread use of air conditioning and cooling systems. As a result, the Power Ministry predicts that peak demand could reach 271 GW this season, which is higher than original estimates. While the IMD expects some relief from thunderstorms and rain starting April 28, they warn that this temperature drop will likely be temporary.

Conclusion

India is currently dealing with a severe heatwave that has pushed electricity demand to record levels, although a short period of cooler weather is expected to begin on April 28.
