TheNorth Chennai Thermal Power Station is apower station situated about 25 kilometres (16 mi) fromChennai city.[1] It is one of the major power plants ofTamil Nadu and has a total installed capacity of 1,830 MW (2,450,000 hp).[2][3][4]
The North Chennai Thermal Power Station was commissioned in 1994 in theThiruvallur district. It was built there due to its proximity to theEnnore Port, which also suppliesEnnore Thermal Power Station. It has won various awards for productivity and reduction in auxiliary consumption.[2][5] The coal necessary for the power station arrives from the Ennore Port.[6] Recently astator was brought to the station via the sea.[7] In recent years, due to a shortage of coal in the state, coal has been imported to operate the power plant.[8]

A 2014 study of coal plants in Southeast India documented extensive environmental impacts from the North Chennai Thermal Power Station, including dumping of large quantities of coal combustion waste into the Buckingham Canal and in nearby marshlands, leaking ash ponds, and discharge of hot water intoEnnore Creek. The impacts have been especially felt by local fishing communities, which have protested the expansion of the plant. Additional impacts have been caused by dredging associated with Ennore Port, which supplies coal to the plant. Environmental activists are demanding that construction on the third phase of the North Chennai Thermal Power Station in Ennore be halted since there is a wide variety of wildlife within the area of the plant that is at risk from continued construction. It is planned for 2019–2020.
The North Chennai Thermal Power Station is polluting the area inAthipattu Pudunagar,Ennore and thus has taken away the livelihood of many residents.Air pollution is one part of it, as toxic gases get free when coal is burned and the dust of the coal that is stored around the plants accesses the lungs while breathing. Data of the Central Pollution Control Board proves that the air in Ennore is unhealthy to breathe.[9] A huge threat to the environment inAthipattu Pudunagar andEnnore is the illegal dumping offly ash by theTamil Nadu Generation and Distribution Corporation (TANGEDCO), which is running the North Chennai Thermal Power Plant. Fly ash from the ash pond of the plant in leaking into theEnnore Creek.[10]Ennore Creek plays a vital role in balancing the coastal ecosystem in the area. Fly ash is a by-product whencoal gets burned and is toxic; it containsheavy metals such asarsenic,boron,cadmium,chromium,mercury andselenium.[11]Heavy metals such asselenium bioaccumulate in fish and harm their ability to reproduce. This affects fish resources and in turn, livelihood of fishermen. In some areas the dumped ash has reduced the depth of the creek from 14 feet below sea level to 2 to 4 feet. This reduces the creek´s ability to carry water, which is crucial, especially in times of flooding and in some areas makes it nearly impossible for fishermen to use their boats on the water. In a recent order the southern bench of theNational Green Tribunal forces TANGEDCO to remove the illegally dumped fly ash from the Ennore Creek. If TANGEDCO fails to do this within one week the two units from it will be shut down at the next hearing. Additionally, TANGEDCO has to repair leaking pipes and come up with a plan how to replace the old ones.[12]
