THE MINISTER OF STATE (INDEPENDENT CHARGE) FOR POWER AND NEW & RENEWABLE ENERGY

( SHRI  R. K. SINGH )

- (a) & (b) : The connectivity between the Southern Grid and Power Grids of  other  regions  are  adequate  to  meet  the  requirements  of  power transmission between Tamil Nadu and other States.
- (c) : The  Southern  Region  (SR)  is  connected  with  the  North-EastWest  Region  (NEWR)  through  various  inter-regional  AC  links  at  220kV, 400KV,  765kV  level  and  HVDC  link.  With  the  commissioning  of  new transmission lines, the grid connectivity upstream and downstream of the main  NEWR-SR  corridor  has  further  strengthened.  The  detail  of  interregional links between SR and NEWR is at Annex.

No congestion has been reported in Day Ahead Market (Power Exchanges) since September, 2017.

- (d) : Green  Energy  Corridor  (GEC)  has  been  planned  to  facilitate integration of large scale renewable generation capacity in eight Renewable Energy resource rich States including Tamil Nadu. It includes strengthening  of  intra-State  and  inter-State  transmission  systems  and establishment of Renewable Energy Management Centres (REMC).

.........2.

The  inter-State  transmission  system  and  REMCs  are  being implemented  by  POWERGRID.  The  project  includes  about  approx.  3200 ckms line and Six Substations of total 18,000 MVA to be completed by May 2019.  Part  of  the  transmission  system  is  commissioned  and  balance transmission scheme is under various stages of implementation. The intraState transmission system is being implemented by the respective State Transmission Utilities (STUs).

The progress of the various schemes under GEC is regularly monitored by Central Electricity Authority/Ministry of Power.
