Transmission System – As of Today • Strong back bone of 400 kV – Overlay of 765 kV & high capacity HVDC under Implementation • All India synchronous grid – One of the largest in the World • Thriving Pan-India Single Market enabled • Under new concept of planning, 10 nos. of high capacity corridors evolved - to reduce the dependency on a particular generation • No congestion in LTA, Congestion only in STOA & MTOA : Total congestion in 2013-14, about 5.6 BU (0.6%) as against annual generation of about 950 BU • Most Advance Load Despatch Centre in Operation

Change in Paradigm Earlier Now • De-licensed/Uncertainty in • Generation is licensed generation • Regional self sufficiency • Connectivity to Generators with limited inter- without PPA/Direction • Open access across the regional allocation nation • Predictable Transmission • Long term Access on Target Region • Economic despatch of generation
