35.  Issues concerning availability of RoW and same are becoming critical –  Resistance of people, terrains in areas of mountains and forest  Sector to grow from 228 GW to 600 GW in next 20 years – Even 765kV system may not be good enough. New methods have to be found out  Challenges to develop Transmission system to meet the requirement of power flow from anywhere to anywhere.  With increasing magnitude of power transmission, create new challenges of proper O&M Issues & Challenges
