TheEnnore Thermal Power Station is a coal basedpower plant located inChennaiEnnore,Tamil Nadu.
Ennore Thermal Power Station was constructed to serve the purpose of energy generation in the year 1970. It is one of the four major thermal power plants ofTamil Nadu established by the Tamil Nadu Generation and Distribution Corporation Limited (TANGEDCO). Presently it has an installed capacity of 450 MW (600,000 hp).[1] The necessary coal arrives through ship to theEnnore Port.[2][3] However, the construction of the 1,000 MW plants (1,300,000 hp) in the premise began in the year 2007.[4][5][6] The Station presently consists of two 60-MW and three 110-MW units. A 500-MW coal-based unit was proposed, and its development started in the month of November 2007.[7] The total cost of the venture was 270crores. The plant was shut down on 31.03.2017 and will be replaced.
The Power Station has been a major provider of electricity in the state and its production capacity has been improved over the years.[8]The Ennore Power Station has also garnered various awards from theTANGEDCO.[1] However power deficit seems to be playing an important role for the recent decision.[9] It also has a special treatment plant to dispose the ash slurry in a proper way.[10]
Coal for ETPS is received from MCL (Talchar and Ib Valley), Orissa and ECL, Raniganj, West Bengal. The plant load factor (PLF) for the year 2008–2009 was 49.17 percent.[11]

It will be replaced with a single Supercritical unit of 660 MW, also run by theTANGEDCO.[12]The replacement does not have clearance yet. The plant is opposed by the residents who fear that the new plant will degrade the air quality and lead to a loss of fishing livelihoods.[13]
