Key Statistics for May 2026

Peak Demand: -

Reached an all-time high of 270.82 GW on May 21, and frequently exceeded 265 GW throughout the late-May solar hours.

Total Consumption:-

 Hit 165 billion units (BU), marking an 11% increase year-on-year.

State Contributions: -

Maharashtra led the load, followed closely by Uttar Pradesh and Gujarat. 

How India Met the Surge

Coal Power:-

 Remains the primary workhorse, consistently supplying over 69% of the energy mix during peak hours. 

Renewable Energy: -

Solar and wind energy accounted for about 19%of the mix, successfully covering a large chunk of the daytime demand during intense solar hours. 

Grid Resilience: -

Despite shortages of under 1%, the grid largely avoided the massive, prolonged outages historically seen in extreme summers.
