The effort to clean up India’s thermal power plants running on coal has never really taken off, despite the Ministry of Environment notifying emission limits for major pollutants such as suspended particulate matter, sulphur oxide, nitrogen oxide and mercury in December 2015. Considering that the cumulative impact of these pollutants on the health and well-being of people is severe, the Centre should have followed up the notification with a viable financial plan to help power plants acquire pollution control technologies. The economics favours such an approach for the larger plants, while for the smaller, older units, scaling down generation during the winter months when pollutants accumulate may prove beneficial. Originally, the compliance deadline was set for 2017, but that was missed and the plan now is to achieve the norms by 2022.
