Existing and New (Revised) Emission Standards for coal based Thermal Power Plants in India

Existing and New (Revised) Emission Standards for coal based Thermal Power Plants(TPPs) in India

Existing Emission Standards:

Particulate Matter (PM) Emission

Parameter        Standard Limits, mg/Nm3

PM                    350 (for <210 MW TPPs)

PM                    150 (for 210 & above MW TPPs

New Emission Standards as per MoEF Notification dated 7.12.2015 :-

1) For new TPPs to be  installed after 1/1/2017. These units includes all those TPPs which have got EC and are under construction.

Parameter                   Standard Limits, mg/Nm3

PM                                         30

SO2                                       100

Oxides of Nitrogen(NOx)  100

Hg                                         0.03

2) For TPPs installed between 1/1/2003 to       31/12/2016, these units have to meet the limits   within two years from the date of MoEF Notification (7/12/2015)

Parameter             Standard Limits, mg/Nm3

PM                                       50

NOx                                    300

Hg                                       0.03

SO2     600 (for <500MW Power Plants)

SO2     200 (for Power Plants of 500MW & above)

3) For TPPs installed before 31/12/2003

Parameter       Standard Limits, mg/Nm3 

PM                         100

NOx                        600

Hg                          0.03

SO2     600 (for <500MW Power Plants)

SO2     200 (for Power Plants of 500MW & above)
