Thermal Power Plants

India is the sixth largest in terms of power generation. About 65% of the electricity consumed in India is generated by thermal power plants, 22% by hydroelectric power plants, 3% by nuclear power plants and rest 10% from other alternate sources like solar, wind, biomass etc. 53.7% of India’s commercial energy demand is met through the country’s vast coal reserves.
Thermal Power Plant sector has been categorized on the basis of their fuel input in to three sub sector i.e. gas, oil and coal based plants. The total reported energy consumption of these designate consumers is about 104 million ton of oil equivalent. By the end of the first PAT cycle, the energy savings of 3.211 million ton of oil equivalent /year is expected to be achieved, which is around 48% of total national energy saving targets assessed under PAT.

This section contains best practices in energy efficiency adopted by thermal power plant sector. The case studies from KEP launch workshop and National Energy Conservation Awards, NECA 2012 and 2013 are presented here.
