Why in news
India recorded a record-breaking peak power demand of 270.8 GW on May 21, 2026, highlighting the strain on the grid and the need for expanded energy storage beyond current roadmaps.
Background
India's peak power demand reached 270.8 GW on May 21, 2026, a significant jump from 180 GW in the same period in 2019. The 2026 Long-Term National Resource Adequacy Plan targets 80 GW of battery energy storage and 94 GW of pumped hydroelectric energy storage (PHES) by FY2035-36.
