The power station comprises three 210 megawatt coal-fired units with which were commissioned between 1994 and 1996, as well as two 600 MW units commissioned in 2013.[1]

Coal supply

Coal for the power station is supplied from Mahanadhi Coalfields Limited (Talchar & IB Valley) in Orissa and Eastern Coalfields Limited at Ranikanj in West Bengal.[2]

TANGEDCO consumes approximately 16 million tonnes of coal a year in its existing coal-fired power stations. Mahanadi Coalfields Ltd. and Eastern Coalfields Ltd. supply 13.5 Million tonnes per annum with the remainder "mainly" imported from Indonesia. The coal is transported by rail from the coal mines to the loading ports namely Haldia, Paradip and Vizag and discharged at Ennore Port and Tuticorin Port. Coal for the North Chennai Thermal Power Station is carried via a conveyer belt from the adjoining Ennore port.[3]


Two 600 MW units (Stage II) were added to the power station in 2013.[4]

Tamil Nadu Generation & Distribution Corporation applied for a terms of reference for another 800 MW unit (Stage III) in 2012,[5] with a proposed completion date of December 2017.[6]

As of August 2014 the company reports that "various studies for obtaining EC are underway."[7] An EIA was submitted in May 2015.[8]
