  • While projects totaling 4,000 MW have already been commissioned during the first 4 years of the Xth plan period, projects totaling 9470 MW are at various stages of implementation. Another 5080 MW is under development. In addition, NTPC would diversify its generation portfolio with increasing presence in Gas and Hydro projects.

    20. 20. Renewable • NTPC plans to add 1000 MW from renewable sources by 2017. • Recently signed MoU for 500 MW of wind power in Karnataka. • MoU with ADB for development of 500 MW from renewable sources. • NTPC has taken major initiatives for fast tracking its solar power development programme. • We hope to set up 15MW solar capacity by 2012 and 50 MW capacity by 2014.Feb 28, 2013 20
    21. 21. Distributed Generation • NTPC has commissioned 10 projects in off-grid distributed power generation mode based on bi- mass, solar PV, micro hydel etc in villages around projects. • Several others are planned as part of CSR activities. • There is also proposal for setting up mini hydel projects at several places in Punjab and North- eastern states.Feb 28, 2013 21
    22. 22. Green Measures • NTPC has created green wealth and carbon sink in the form of more than 18 millions trees planted in and around plant areas. • NTPC has started implementing modern water harvesting systems in all upcoming townships in the projects for better management of water. • NTPC is committed for development of 1 million Sq feet of green building space within NTPC premises. • Energy Conservation can also play a major role; NTPC has adopted practices like Online Energy Management Systems, Energy Audit, Water-balance Audit for main plant and BOP equipments. As per study conducted by National Remote Sensing Agency, Hyderabad, the summer peak temperatures in areas surrounding Ramagundam Thermal Power Station of NTPC where about 1.2 million treesFeb 28, 2013 have been planted, has reduced to the extent of 30 C. 22
