Road Map for Indian Power System
• Creation of reliable repairing facilities & development
of 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
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
Issues & Challenges
