High-Power Interconnections for Future of Indian Mega Cities

Data compiled by studies estimates that total electric energy requirement for the 13 of present Indian mega cities by the end of 12th Plan will be about 168 BU and by end of 13th Plan the requirement would be 233 BU. Also the ambitious plan of developing 100 smart cities by Indian government requires energy security both in decentralized and centralized manner. So in order to meet these demand future Indian cities requires a strong power link so that huge amount of power can be bought into the cities, for which Gas Insulated Transmission Lines (GIL) can be thought of as an ultimate solution for the problems caused by over-head line or underground cable running through cities. This paper addresses how new possibilities can mitigate power flow problems, reduce the risk of failure of electrical transmission systems and enable the installation of optimum solutions regarding technical, economical and environmental aspects.
