Lignite for the power project is being supplied from the Neyveli lignite mine, which is owned and operated by NLC.[1]

On its website NLC states that the anticipated phase out of Neyveli Thermal Power Station I between 2009 and 2014 is "due to ageing of the plant". On its website NLC states that:

"it has been proposed to set up a power plant at Neyveli with a capacity of 2 x 500 MW, for which MOC has accorded sanction for the advance action proposals including for carrying out certain studies in respect of augmentation of existing mines. Preliminary activities such as preparation of Feasibility Report, Environmental studies, Contour Survey and Soil investigation study are in progress. Our company has initiated action for obtaining Mega Power Project status for this project so as to avail certain concessional duties. The estimated cost of the power project is Rs. 5000 crores."[2]

In January 2014, NLC said the power station would be commissioned in 2017-2018.[3]

In December 2016, and March 2017 the India Ministry of Power listed the scheduled commissioning of the plant for 2018.[4][5]

On December 28, 2018, NLC India conducted the boiler light-up test for the first unit, an initial step toward commissioning.[6]

Unit 1 was commissioned in September 2019.[7] Unit 2 was commissioned in February 2021.[8]

In January 2023, a proposal to amend the Environmental Clearance (EC) dated 21.10.2010 was assessed and denied (returned in "present form") by the Expert Appraisal Committee (EAC). The EAC determined "[t]he project proponent could not justify that amendment requested will not pose negative impact on the surrounding environment. It was also noted that PP has not submitted the certified compliance report of existing environmental clearance. It is necessary to have a detailed study on the possible environmental impacts on application of industrial waste water into agricultural fields in the nearby area of the project site by the reputed expert institute."[9]

According to the agenda of the EAC's 11th meeting (to be held in late June 2024), the project proponent had submitted a new proposal for amendments to the project's EC.[10]


In April 2012, the State Bank of India agreed to provide the project with a US$490 million loan.[11]

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.[12][13]
