The Ennore Thermal Power Station is a coal based power plant located in 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 of Tamil Nadu established by TANGEDCO. Presently it has an installed capacity of 450-MW.[1] The necessary coal arrives through ship to the Ennore Port.[2][3] However the construction of the 1000 MW plants 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 is proposed and its development started in the month of November 2007.[7] The total cost of the venture was 270 crores.


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 the TANGEDCO.[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]

The Ennor Thermal Power Station has been handed over for improvements. A SEZ project is being discussed at the site.[12][13] The new project will use the latest technology to enhance the output.The Proposal also talks about a super-critical procedural implementation.[14] In recent years due to shortage of coal in the state, coal is being imported to function the power plant.[15]
