11 coal-based power plants around Capital not complying with emission norms: Study

The 11 coal-based thermal power plants (TPPs) that fall within a 300-km radius of Delhi are not complying with emission control norms and are likely contributing to the prevailing high pollution levels in the national capital region (NCR), according to a new analysis carried out by the Centre for Science and Environment (CSE).

The analysis, released on Sunday, said that out of the 11 plants, all but one were exceeding the sulphur dioxide (SO2) norms, three were exceeding particulate matter (PM) norms, four were exceeding nitrogen oxide (NOx) emission norms, and five were not maintaining adequate emissions data in the public domain.

The study also said that only two plants were using flue-gas desulfurisation (FGD) - a technology mandated by the Union environment ministry to be installed to reduce SO2 emissions.

HT on November 22 reported that nine of these power plants have missed at least four deadlines to switch to this technology.
