India’s electricity demand is witnessing a major structural shift as rising heatwaves, urban temperatures and cooling needs push the national power grid to record-breaking levels.

• India recorded an all-time peak electricity demand of 270.8 gigawatt on May 21, 2026 amid severe heatwave conditions across multiple states.
• Residential cooling demand driven by air conditioners and cooling appliances is now growing faster than industrial electricity demand in several regions.
• Rapid urbanisation and the Urban Heat Island effect are increasing temperatures in Indian cities by nearly 2°C to 10°C above surrounding areas.
• Solar energy contributed nearly 80 gigawatt or around 22 percent of total electricity supply during daytime peak demand hours.
• Rising nighttime temperatures are forcing households to use cooling systems for longer durations, increasing electricity demand even after sunset.
• High humidity levels are worsening “feels like” temperatures in coastal and monsoon-influenced regions, boosting dependence on mechanical cooling.
• Experts warned that weak power infrastructure and reduced renewable balancing capacity are increasing pressure on grid stability during evening hours.
• The report recommended cool roofs, rooftop solar systems, smart grids, energy-efficient appliances and urban green infrastructure to reduce future electricity stress.
