As large parts of India continue to reel under intense heatwave conditions, the use of air conditioners, coolers, fans and other cooling appliances has surged sharply, driving electricity consumption to unprecedented
levels this summer. Despite the spike in demand, India successfully met a record peak power demand of 260.45 GW on Tuesday.
Sharing the update on X, the Ministry of Power said, “Today, the peak power demand (solar hours) of 260.45 GW was successfully met at 15:40 hrs. This is a new high, surpassing yesterday’s peak demand (solar hours) of 257.37 GW, which was also successfully met.”
The rise in electricity demand comes amid soaring temperatures, with the mercury crossing 45 degrees Celsius in several states and significantly increasing cooling requirements during daytime hours.
Delhi also witnessed its highest power demand of this summer season on Tuesday. According to the State Load Dispatch Centre (SLDC), the national capital’s peak electricity demand touched 7,776 MW at 3:30 pm.
India’s 260.45 GW is significantly higher than the combined peak electricity demand of several other South Asian nations. Pakistan’s peak load stands at around 28.3 GW, Bangladesh at 16.5 GW, Sri Lanka at 3 GW, Nepal at 2.2 GW, Bhutan at 1.2 GW, and Afghanistan at 0.8 GW. Together, the combined peak demand of these countries is estimated at nearly 52 GW. This means India’s national power grid is currently handling more than five times the instantaneous electricity load of all its South Asian neighbours combined.
How India Is Meeting Unprecedented Electricity Demand
India successfully met the surge in electricity demand this summer through advance resource adequacy planning, optimal scheduling and dispatch of available generation resources, and close real-time coordination among the National Load Dispatch Centre (NLDC), Regional Load Dispatch Centres (RLDCs), State Load Dispatch Centres (SLDCs), and generating stations. Efficient utilisation of transmission corridors also played a key role in maintaining uninterrupted supply.
At the time of peak demand, the power requirement was met through a diverse energy mix comprising thermal, hydro, nuclear, gas, wind, solar, and storage-based generation, ensuring grid reliability and stability despite scorching temperatures across several parts of the country.
When India recorded its all-time highest peak electricity demand of 256.1 GW on April 25, 2026, thermal power remained the backbone of the country’s electricity supply, contributing 174,565 MW, or nearly 67% of the total generation. Renewable energy sources also played a significant role in meeting the record demand, with solar power alone contributing 56,204 MW — more than 21% of the total generation during peak hours. Hydro power added 11,422 MW, while wind energy contributed 4,897 MW to the national grid.
Nuclear energy generated 6,293 MW, accounting for 2.4% of the total supply, while gas-based plants contributed 5,205 MW. Storage systems, including Pumped Storage Projects (PSP) and Battery Energy Storage Systems (BESS), supplied 201 MW during peak conditions, while other sources together added 2,110 MW to the grid.
Officials said the diversified generation portfolio and coordinated grid management helped India meet record electricity demand without major disruptions during the ongoing heatwave season.
