India's Peak Power Demand Surges to 270 GW Amidst Record Heatwaves
India's power demand hit a new peak of 270 GW in May, driven by severe heatwaves across the country, marking the fourth consecutive monthly record. The surge has pushed temperatures above seasonal norms in several regions & is straining infrastructure.
Soaring Power Consumption Driven by Heat
India's peak power demand reached a new high of 270.82 gigawatts (GW) at 3:45 PM on Thursday, May 21. This marks the fourth consecutive month that the country has seen its power demand surpass previous records, primarily due to extreme temperatures and prolonged heatwaves affecting numerous regions.
The demand trends for May have already exceeded the 243 GW peak recorded in June of the previous year. In May 2023, the peak reached 231 GW. Thursday's demand also exceeded the all-time high of 265 GW, which occurred in solar hours the day prior.
Heatwave Intensifies Across Northern India
Current conditions indicate a prominent heatwave, influenced by El Nino. This phenomenon has substantially increased cooling requirements and, consequently, power demand. Predictions suggest that mercury levels may continue to climb in the coming weeks, potentially pushing demand past the 275 GW mark, breaking further records.
Thursday marked the fourth consecutive day of heatwave conditions in Delhi, according to the Indian Meteorological Department (IMD). The IMD forecasts that the likelihood of lower tropospheric dry Northwesterly and Westerly Winds, along with the absence of significant western disturbances, will contribute to continued heatwave conditions across the plains of Northwest India, including Delhi, over the next seven days.
Several northern and central Indian cities recorded significantly high temperatures. Banda, Uttar Pradesh, registered 47.6°C, 4.1°C above normal. Brahmpuri, Maharashtra, hit 47.1°C, 4.5°C above normal. Rajnandgaon, Chhattisgarh, saw 47.0°C, a notable 8.1°C above normal. Chandrapur, Maharashtra, reached 46.8°C (3.9°C above normal), and Prayagraj, Uttar Pradesh, recorded 46.6°C (5.3°C above normal).
Infrastructure Under Strain
The city's power demand peaked at 8,231 megawatts (MW) for 2026, marking the highest level in the first 21 days of May.
BSES stated that its distribution companies are prepared to ensure reliable power supply to over 5.3 million consumers and nearly 22.5 million residents across South, West, East, and Central Delhi. These arrangements involve long-term power purchase agreements (PPAs), bilateral tie-ups, banking arrangements with other states, and the deployment of advanced technologies, including artificial intelligence.
Shyamasis Das, a fellow at the Centre for Social and Economic Progress, noted that the summer of 2025 was largely moderate across most parts of India, particularly in the northern areas, with intermittent spells of rain and a wetter monsoon. This contrasts sharply with the current escalating demand.
