NIAS Transition Plan for Thermal Power Plants in India
The NIAS Transition Plan for Thermal Power Plants (TPPs) recommends the progressive retirement of obsolete TPPs while shifting the load to existing and under-construction, modern TPPs and Nuclear Power Plants (NPPs) instead of retrofitting them with costly Flue Gas Desulfurisers (FGDs). Stack heights mandated for TPPs in India are designed to disperse SO2 emissions to ensure that ambient air SO2 levels comply with National standards.
