Grid Under Strain as Power Demand Soars
India's electricity grid is facing unprecedented pressure as peak power demand reached a record 270.82 GW on Thursday, marking the fourth consecutive day of surpassing previous highs. This surge is directly linked to a relentless heatwave gripping the nation, which has dramatically increased the use of cooling systems and pushed electricity consumption to historic levels. The Ministry of Power has confirmed that supply has met this demand, but officials are closely watching both current and projected peak demand figures, with estimates suggesting June's demand could reach 283 GW.
Energy Sources Under Pressure
On Thursday, the energy mix consisted of 62.8% thermal power, 22% solar, 5% wind, and 5.8% hydro. Thermal power continues to be the primary source of electricity, but solar energy is making a substantial daytime contribution, accounting for up to 32% of the power supply. Despite assurances that coal stocks at thermal plants are adequate and supply chains are being effectively managed, the continuous rise in demand, especially during periods without solar generation, presents a persistent challenge for grid operators.
Historical Demand Peaks and Future Outlook
This year's power demand has already surpassed previous summer peaks. In May 2024, the peak demand reached 250 GW, and the previous summer's peak was 242.77 GW in June 2025. The current trend indicates that demand is likely to continue rising, with predictions that peak demand could surpass 275 GW in the coming weeks. Experts emphasize the need for ongoing investment in renewable energy capacity, energy storage solutions like batteries, and upgrades to transmission infrastructure to ensure the grid's reliability as demand grows.
Economic Repercussions of Extreme Heat
The severe heatwave is not only testing the power grid but also creating significant economic risks. Projections indicate that extreme heat could cost India between $150 billion and $250 billion by 2030, potentially impacting the country's GDP by 2.5% to 4.5%. The early and intense arrival of summer this year, with temperatures frequently exceeding 40°C and reaching as high as 48°C in some areas, has accelerated electricity consumption, disrupting traditional demand patterns. In response, the government is preparing an emergency strategy, which includes deferring all planned maintenance at power plants through June and July, to strengthen supply capabilities and manage the anticipated peak demand of 283 GW.
