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

Earlier

  • Generation is licensed
  • Regional self sufficiency

with limited inter- regional allocation

  • Predictable Transmission

Change in Paradigm

Now

  • De-licensed/Uncertainty in

generation

  • Connectivity to Generators

without PPA/Direction

  • Open access across the

nation

  • Long term Access on Target

Region

  • Economic

despatch

  • f
