India’s electricity demand is rising rapidly due to economic growth, increasing air conditioner ownership, and higher temperatures, with power consumption growing about 5% annually since 2019. While record additions of solar power have helped meet daytime demand, the country is facing a growing challenge in supplying electricity during hot summer nights when cooling needs remain high and solar generation is unavailable.
A severe heatwave in May 2026 pushed peak demand to a record 270 GW, highlighting the strain on the power system. Nighttime temperatures are rising faster than daytime temperatures, increasing reliance on air conditioning after sunset. Although solar energy has expanded rapidly, India still depends heavily on dispatchable sources—particularly coal—to meet evening and overnight demand. The IEA says batteries, energy efficiency measures, grid upgrades, and a diversified mix of generation and storage technologies will be critical to maintaining electricity security as demand continues to grow.
