In order to reduce carbon emissions and environmental impact of coal-based thermal power generation, Indian government has taken some major steps.
The Ministry of Power is promoting installation of efficient Supercritical or Ultra Supercritical units that are more efficient and leading to reduced CO2 emission per unit of electricity generation. A total capacity of Supercritical or Ultra-supercritical units of 70,190 MW (101 Units) and 7,680 MW (11 units) have been commissioned respectively till 31.10.2025.
To improve the energy efficiency, the Perform Achieve and Trade (PAT) scheme has been implemented in various thermal power plants.
Ministry of Power has issued a comprehensive policy on 07.11.2025 for co-firing of bio-mass pellets [including torrefied charcoal made from Municipal Solid Waste (MSW)] in Coal Based Power Plants to use 5-7% blend of biomass pellets and/or MSW-based torrefied charcoal along with coal, after assessing the technical feasibility.
MoEF&CC vide notification dated 07.12.2015 and its subsequent amendments has notified norms in respect of reducing stack emissions such as Suspended Particulate Matter (SPM), Sox & NOx from coal based thermal power plants. To meet these standards, Thermal Power Plants are using techniques like ElectroStatic Precipitator (ESP), Flue Gas Desulphurization (FGD), NOx Combustion Modification etc.
