NTPC retrofitting old plants to meet revised emission norms

New Delhi, Jul 8: Seeking to bring down emission levels of all old power plants to revised stringent standards by 2022, the state-run National Thermal Power Corporation (NTPC) has started retrofitting such plants with necessary equipment. The very old coal-based plants may, however, be closed down in a phased manner if retrofitting is not feasible.
“We have a plan in place, wherein from 2019 onwards and by 2022, emission levels of all old power plants will be brought to national standards. Some may be closed which are very old, but rest will be done (retrofitted),” said Union environment secretary C K Mishra.
His assurance came in the backdrop of the extension of the deadline for the thermal power plants to meet the emission standards. He was speaking at a conference – The Earth Dialogues – on Wednesday.
The environment ministry had in 2015 notified the new standards and set the deadline of December, 2017 for the necessary retrofitment. The new standards are aimed at reducing emission of PM10, sulphur dioxide and oxide of nitrogen which will, in turn, help in bringing about an improvement in the Ambient Air Quality (AAQ).
The ministry had, however, later aligned itself with the Central Electricity Authority’s (CEA) plea for five years extension on the ground of practical difficulties, arguing that the retrofitment has to be done in phases to avoid problem in the power supply as too many units cannot be taken out for retrofitting at the same time.
