## UTILISATION OF PSDF FOR INTER STATE TRANSMISSION NETWORK

4289.  SHRIMATI RATHVA GITABEN VAJESINGBHAI:

Will the Minister of POWER be pleased to state:

- (a) the capacity of present transmission lines;

(b) whether the Union Government proposes to run these transmission lines in its full capacity and if so, the details thereof;

(c) whether the State Government of Gujarat is unable to supply surplus power to power deficit States due to constraints in inter-regional transmission corridors and if so, the details thereof;

(d) whether the Union Government has any plan for power deficit States and if so, the details thereof;

- (e) whether  the  State  Government  of  Gujarat has  requested  the  Union Government  to  utilize  the  funds  lying  in  Power  System  Development  Fund (PSDF)for  creation  of  sufficient  inter-regional  transmission  links  and  if  so,  the details thereof; and

(f) whether the Union Government proposes to use PSDF for establishing interState transmission network and if so, the details thereof?

THE  MINISTER  OF  STATE  (INDEPENDENT  CHARGE)  FOR  POWER,  NEW  & RENEWABLE ENERGY AND THE MINISTER OF STATE FOR SKILL DEVELOPMENT & ENTREPRENEURSHIP

( SHRI  R.K. SINGH)

(a) : The  total  circuit  kilometers  (ckm)  of  transmission  lines  at  the voltage level of 220 kV and above in the country is 4,15,517 ckm as on 30.6.2019.

- (b) : The transmission  lines  are  allowed  to  be  run  to  their  full  capacity wherever  it  is  permissible  in  accordance  with  Regulations/standards  of  Central Electricity  Authority  (CEA)/Central  Electricity  Regulatory  Commission  (CERC). However,  in  certain  cases,  the  loading  on  transmission  lines  may  have  to  be restricted keeping in view the voltage stability, angular stability, loop flows, load flow pattern and loading of weakest link in the grid.

(c) : Presently,  there  is  no  constraint  in  the  Inter-State  Transmission System (ISTS) for transfer of long term allocated power from various generating stations in Gujarat to different beneficiary States.

(d) : Augmentation  of  the  ISTS  network  is  a  continuous  process  and  is being carried out regularly based on implementation of new generations projects, growing  power  demand,  to  address  operational  constraints  etc.  A  number  of transmission  lines are  under  implementation  which  would  facilitate  power transfer from resource rich Western Region to power deficit areas, the details are as under :

- (i)
- (ii)
- Warora-Warangal 765 kV D/C line
- 600 MW, + 800 kV Raigarh - Pugalur HVDC bipole line
- (iii) Upgradation  of  +  800  kV  Champa  -  Kurukshetra  HVDC  bipole  line from 3000 MW to 6000 MW
- (iv) Vindhyachal-Varanasi 765 kV D/C line

(e) & (f): Based on the proposals of Gujarat, 9 schemes have been approved for which about Rs.400 crores has been sanctioned.

The funds  from  PSDF  are  utilized  for  the  categories  of  projects  as given below:

-  Creating  necessary  transmission  systems  of  strategic  importance  for relieving congestion in Inter-State Transmission Systems (ISTS) and intrastate system which are incidental to the ISTS.
-  Installation  of  shunt  capacitors,  series  compensators  and  other  reactive energy generators for improvement of voltage profile in the Grid.
-  Installation of standard and special protection schemes, pilot and demonstrative projects, projects for setting right the discrepancies identified in the protection audits on regional basis, any communication/measurement/ monitoring  scheme including installation  of Phasor Measurement Units (PMUs) etc.
-  Renovation  and  Modernization  (R&M)  of  transmission  and  distribution systems for relieving congestion.
-  Any other scheme/project in furtherance of the above objectives, such as, conducting technical studies and capacity building, etc.
