More than 65% of India's electricity generation capacity comes from thermal power plants, with 85% of the country's thermal power generation being coal-based. The ten biggest thermal power stations operating in India are all coal-fired, with five of them owned and operated by state-run National Thermal Power Corporation (NTPC).

Coal: In a coal based thermal power plant, coal is transported from coal mines to the generating station. Generally, bituminous coal or brown coal is used as fuel. The coal is stored in either 'dead storage' or in 'live storage'. Dead storage is generally 40 days backup coal storage which is used when coal supply is unavailable.
