in Tamil Nadu. The company is also setting up 1209 MW Solar Power Projects at Tirunelveli, Virudhunagar and Ramanathapuram districts of Tamil Nadu, of which, 300 MW have been commissioned. NLC is aiming to achieve a total renewable energy capacity of 4251 MW. NLCIL has a target of becoming a 20,000+ MW company by 2025. Works are under progress for the lignite based Neyveli New Thermal Power Plant (1000 MW), Bithnok TPS and Barsingsar TPS Expansion (each 250 MW). Further, NLC, jointly with the Uttar Pradesh Rajya Vidyut Utpadan Nigam Limited (UPRVUNL), is setting up a 3x660 MW coal based thermal power plant at Ghatampur in Uttar Pradesh, through its subsidiary company Neyveli Uttar Pradesh Power Limited (NUPPL) (equity participation in the ratio of 51:49). Apart from the above, the addition of thermal capacity to the tune of 6040 MW by way of installation of new plants and acquisition of power assets to the tune of 3000 MW is in the pipeline. NLC has also contributed significantly to the socio-economic development for more than half a century. The Business portfolio of the company is as under: Chronology of events Power projects NLC India has five pithead Thermal Power Stations with an aggregate capacity of 4240 MW. Further, NLC India has so far installed 51 wind turbine generators of capacity 1.50 MW each and also commissioned 140 MW solar photo voltaic power plant in Neyveli, resulting in an overall power generating capacity of 4431 MW (excl. JVs). Thermal Power Station I The 600 MW Neyveli Thermal Power Station-I in which the first unit was synchronized in May 1962 and the last unit in September 1970 consists of six units of 50 MW each and three units of 100 MW each. Power generated from Thermal Power Station-I after meeting NLC's requirements is supplied to TANGEDCO, Tamil Nadu which is the sole beneficiary. Due to the aging of the equipments / high-pressure parts, the Life extension programme has been approved by the Indian Government in March 1992 and was completed in March 1999 thus extending the life by 15 years. Given the high grid demand in this region, this power station is being operated after conducting the Residual Life Assessment (RLA) study. Indian Government has sanctioned a 2x500 MW Power Project (Neyveli New Thermal Power Plant – NNTPS) in June 2011 as a replacement for existing TPS-I. Thermal Power Station II The 1470
