Units 1-9
The power station, which originally comprised six 50 MW units and three 100 MW units, was commissioned between 1962 and 1970. Lignite for the power project is supplied from the Neyveli lignite mine, which is owned and operated by NLC.[1]
Retirements
After the construction of two new units (10-11), the power station's nine original units were all decommissioned by the following dates (DD.MM.YYYY):[2][3]
- Unit 7: 06.02.2019[4]
- Units 1, 9: 31.03.2020[5]
- Units 2, 4, 8: 08.07.2020
- Unit 3: 30.07.2020
- Unit 5: 5 28.09.2020
- Unit 6: 30.09.2020[6]
Units 10-11
In the mid-1990's the government approved the expansion of the Neyveli Thermal Power Station by two 210 MW units. The new units were commissioned in September 2002 and March 2003. Lignite for the new units was catered from a 4 million tonne a year expansion of the existing Neyveli lignite mine.[7]
Reported pollution
In August 2023, an analysis of environmental impacts from several coal plants and mines in Tamil Nadu found widespread air, soil, and water pollution. New Neyveli Thermal Power Station, Neyveli Thermal Power Station I, Neyveli Thermal Power Station II, and Cuddalore IL&FS power station were included in the study, which was conducted by Poovulagin Nanbargal (Friends of the Earth Tamil Nadu) and the research NGO Manthan Adhyayan Kendra. The study found high concentrations of mercury, selenium, and fluoride in several drinking water sources near NLC mines and power stations. Water samples near the IL&FS plant in Parangipettai contained fluoride, iron, calcium, magnesium, and silicon above legal limits. The report recommended stricter regulation of the mines and power plants and measures to cut effluent discharges and the dumping of coal ash in local waterbodies.[8][9]
