Techno-economic analysis of 765 kV transmission in India

The development of extra and ultra high voltage transmission lines are becoming essential due to ever increasing energy demand worldwide. In order to strengthen the transmission infrastructure, transmission utilities are aiming at constructing high voltage and high power intensity power transmission lines for meeting the energy requirements with maximum possible efficiency and minimum adverse environmental effects. Extra and ultra high voltage transmission lines have been developed and being operated successfully in the developed nations. Recent trends in Indian transmission scenario are progressing towards establishing these lines. In the present study, an attempt has been made to present the design aspects of 765 kV transmission lines briefly. A detailed techno-economic analysis evaluating the benefits and costs resulting from these lines in power transmission has been carried and the results are summarized.
