India's power sector has reached a widely publicised capacity milestone: non-fossil sources crossed 50 per cent of total installed generation capacity in June 2025, five years ahead of the target set under India's Nationally Determined Contribution, and independent capacity trackers report that clean energy sources overtook fossil-fuel capacity for the first time by August 2026. Yet these capacity-side achievements coexist with a far more modest transformation in actual electricity generation: non-fossil sources supplied only 29.2 per cent of total output in FY 2025–26, and coal alone continued to generate more than two-thirds of the country's electricity. This paper undertakes a descriptive-comparative analysis of India's installed capacity mix and its generation mix over 2014–2026, drawing on official data from the Ministry of Power, the Ministry of New and Renewable Energy, the Press Information Bureau, and independent trackers including Ember, Global Energy Monitor, and Climate Action Tracker. The analysis documents a widening structural gap between capacity growth and generation growth, driven principally by the differential in capacity utilisation between intermittent renewable sources and dispatchable thermal plants, compounded by rapidly rising electricity demand and limited grid-scale storage. The paper argues that capacity statistics, while a valid signal of investment direction and future intent, should not be conflated with the present composition of electricity actually consumed, and that closing the gap requires sustained investment in transmission, storage, and demand-flexibility infrastructure rather than capacity addition alone. The paper concludes with policy implications and directions for future empirical research.
