India's power consumption up 4% to 153.99 BU in April as peak demand hits record 256 GW
Synopsis
Key Takeaways
India's power consumption rose 4.04 per cent to 153.99 billion units (BU) in April 2026, compared to 148.01 BU in the same month a year earlier, according to official data released on 1 May. Demand remained subdued in the first half of the month as unseasonal rains kept temperatures in check, before surging sharply as a heat wave gripped large parts of the country.
Record Peak Demand on April 25
India's peak power demand soared to a record high of 256.11 GW on 25 April 2026, as an intensifying heat wave drove both domestic and commercial consumers to ramp up use of air conditioners and other cooling appliances, according to data compiled by the Ministry of Power. The figure surpasses the previous summer's peak of 242.77 GW, which was recorded in June 2025 and had itself stayed below the government's then-estimate of 277 GW.
What Drove the Demand Surge
Temperatures across several regions rose significantly — in some areas by 5 degrees Celsius or more above normal — signalling a developing heat stress scenario, according to the India Meteorological Department (IMD). The sustained rise in temperatures since mid-April translated into a steep jump in electricity consumption. Experts note that the first half of April saw relatively muted demand due to unseasonal rainfall, making the second-half surge all the more pronounced.
Summer Outlook and Government Projections
The Ministry of Power has estimated peak power demand could reach 270 GW for the current summer season. Experts broadly concur, saying consumption will continue climbing from May onwards. The IMD has issued a warning of intense heatwave conditions across India from April to June 2026, with above-normal heatwave days expected across the northern Indo-Gangetic plains, central India, and eastern coastal states. Temperatures could exceed 45 degrees Celsius in several regions, with high humidity compounding risks to life and infrastructure.
Solar Energy Cushions the Grid
Solar power is increasingly absorbing a significant share of the rising load. As per the Ministry of New and Renewable Energy, India crossed 150.26 GW of installed solar capacity as of 31 March 2026, marking one of the fastest expansions in the country's energy history. Record annual additions in FY 2025–26 have positioned solar as India's fastest-growing power source, reducing — though not eliminating — dependence on fossil fuels during peak demand periods.
What to Watch
With the IMD projecting a prolonged and harsh summer, power utilities and grid operators face a high-stakes test of grid reliability. Whether peak demand breaches the 270 GW government estimate — or stays below it as it did last year — will depend on the monsoon's arrival timeline and the severity of heatwave episodes in May and June.
