Thermal power plants are the largest source of electricity in India.
India’s electricity generation mix is dominated by thermal power, primarily coal-based power plants. Although renewable energy sources (like wind and solar) are rapidly growing, and hydro and nuclear power contribute, thermal power accounts for the largest share of total installed capacity and actual generation.
As of recent data, thermal power (including coal, gas, and diesel) constitutes over 50% of India’s total installed electricity generation capacity, and its contribution to actual generation is even higher due to higher capacity utilization compared to some renewable sources.
