India's Peak Power Demand Hits 270.82 GW on a Fourth Straight Record Day as Heat Grips the North

India's peak electricity demand reached a new all-time high of 270.82 GW on 21 May 2026, the fourth consecutive day of record demand, the Power Ministry said. The peak was met at 15:45 during solar hours. The ministry attributed the surge to heavier use of cooling appliances during a heatwave across northwest and central India, where temperatures crossed 47°C in several places. The figure matched the ministry's own estimate for peak demand in the 2026 to 2027 fiscal year, which it had put in the range of 270 GW.

The ministry said the peak was met with thermal generation supplying 62.8%, solar 22%, hydro 5.8%, wind 5% and other sources the remainder. The share of solar at the afternoon peak reflects the rapid growth of India's solar capacity, which has made daytime peaks easier to meet. Disha Aggarwal of the Council on Energy, Environment and Water, a New Delhi think tank, told The Hindu BusinessLine that a 256 GW peak in the week of 20 April had already shown how thin margins were becoming.

She called for fast-tracking 9.7 GW of battery and pumped hydro storage planned for the fiscal year, maintaining coal stocks at plants far from mines, expanding time-of-day tariffs for smart-metered consumers, and giving distribution companies weather-linked forecasting tools to anticipate demand hotspots and prevent transformer failures. Delhi also set a record for the year, with peak demand of 8,231 MW at 15:31 on 21 May, up from 8,039 MW the day before. India's peak demand has risen steadily over the past decade with economic growth, urbanisation and rising ownership of air conditioners and other appliances.

India's power system remains heavily dependent on coal, which supplied close to two-thirds of the peak. Gas-fired plants play a smaller role in India because of the high cost of imported LNG. India has set a target of 500 GW of non-fossil capacity by 2030 and has been adding large volumes of solar each year.
