Need of new initiatives in Transmission

 Increased role of ISTS power transfer  Need of long distance Transmission system  Minimum use of land and Right-of-Way  Optimal cost per MW transmission  Optimal Transmission Losses  Adequate margin – to cater trading, contingencies  Implementation – Equipment availability, manpower

Road Map for Indian Power System

• Creation of reliable repairing facilities & development
• f indigenous manufacturing capacity
• Need to establish reliable testing facilities for EHV and

UHV

• Development of Smart Grid for real-time monitoring of

dynamic state and optimal utilisation of facilities

Issues & Challenges

SLIDE 21

Road Map for Indian Power System

• Issues concerning availability of RoW and land are

becoming critical –

– Resistance of people, terrains in areas of mountains and forest

• Sector to grow from 173 GW to 600 GW in next 20

years – Even 765kV system may not be good enough. New methods have to be found out

• Cable manufacturers need to Research & develop

cables which could be more cost effective

• With increasing magnitude of power transmission,

new challenges of proper O&M
