Singareni Thermal Power Plant : First Public Sector Coal-Based Power Generating Station

Singareni Thermal Power Plant (STPP) in Telangana is set to become the first public sector coal-based power generating station in the South and first among the State PSUs in the country to have a flu gas desulphurization (FGD) plant.

• With 100% utilisation of the fly ash generated, the STPP has won the best fly ash utilisation award twice already
• The FGD plant would process the sulphur and other gases (nitrogen oxides) generated in firing the coal for power generation.
• The FGD plant removes Sulphur Dioxide from the flue gas before it is released into the atmosphere and hence reduces its impact on the environment.
• FGD systems are characterized as either “wet” or “dry” corresponding to the phase in which the flue gas reactions take place.
• The Ministry of Environment, Forest and Climate Change (MoEF&CC) has set the deadline for installation of FGD plants for coal-based power plants as December-end of 2026 for non-retiring plants and as December-end of 2027 for retiring plants.
• However, it is not made compulsory for the plants that are going to retire by December-end of 2027, provided they seek exemption from the Central Pollution Control Board and Central Electricity Authority.
