A two-year old study released in 2015 by the
Centre for Science and Environment (CSE), (a well-respected non-profit public
interest research and advocacy organization in New Delhi) concluded that NTPC,
India's largest power producing Coal Company was way below the prevailing
standards across various parameters. The study, which analyzed 47 plants over
16 states, established the Badarpur plant as the country's most polluting power
plant. The study on the Badarpur plant The study called 'Heat in Power' analysed
and rated coal-based thermal power plants on nearly 60 environmental and energy
parameters. It rated 40% of the plants (around 18 of the 47) as having a score
less than 20%, based on various parameters. NTPC Ltd.'s Badarpur plant was
declared the poorest performing of all. This plant which contributed a
relatively meagre share of Delhi's power (7.9% during April to October 2015)
contributed around 80-90% of the particulate matter, SOx and NOx (Major
pollutants) from the energy sector in Delhi. As such it was ranked poorest on
the parameters of environmental performance and energy efficiency.
