According to the latest capacity data from Ember and Global Energy Monitor (GEM), clean energy sources now account for 331.7 gigawatts (GW) of installed capacity, compared with 302.0 GW for fossil fuels.
Non-fossil energy sources now form a majority of India's power generation capacity for the first time, reaching 331.7 gigawatts (GW) compared with 302.0 GW for fossil fuels, according to data from Ember and Global Energy Monitor (GEM). The shift highlights a growing divergence between the fuel types driving current electricity generation and those shaping future capacity expansion.
While coal still supplies roughly 70 percent of actual electricity output due to its ability to operate continuously, investment patterns show a decisive pivot toward renewable infrastructure. Solar generation accounts for the bulk of non-fossil growth, rising from 0.07 GW in 2010 to 211 GW, which makes up about 33 percent of the country's total utility-scale installed capacity.
India's solar capacity now approaches its total coal capacity of 254.4 GW and exceeds the entire national power grid's capacity of 211.4 GW recorded in 2011. Solar growth has vastly outpaced fossil additions in recent periods, with 75.5 GW of solar added between 2025 and mid-2026 compared to 3.8 GW for coal. Total clean energy capacity grew by almost 80 GW over that span, whereas fossil capacity expanded by 5.4 GW.
Although fossil fuel capacity continues to increase in absolute terms to support surging electricity demand, coal's relative share of installed capacity dropped from nearly 59 percent in 2014 to 40 percent in 2026. Overall fossil fuels, which represented almost three-quarters of installed capacity in 2000, now constitute under half of the total mix.
Solar energy has emerged as the dominant clean energy technology in the country, reaching a scale approximately four times larger than hydro or wind capacity. Currently representing about 80 percent of total coal capacity, solar output is projected to surpass coal as the largest single installed capacity category within ten years if current installation trends continue.
To convert this capacity growth into greater shares of actual power generation, the power sector must address grid integration challenges. Experts emphasize that future progress will require substantial investment in transmission infrastructure, energy storage, and flexible balancing resources to accommodate high volumes of intermittent solar generation.
