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 National Electricity Policy 2005 recognized that Transmission System requires coordinated action to develop a robust and integrated power system for the country.  Keeping  in  view  the  massive  increase  planned  in  generation  and  also  for development  of  power  market,  the  policy  emphasized  that  the  Central  Government would  facilitate  the  continued  development  of  the  National  Grid  for  providing adequate  infrastructure  for  inter-State  transmission  of  power  and  to  ensure  that underutilized generation capacity is facilitated to generate electricity for its transmission from surplus regions to deficit regions.

Towards this, development of National Grid was undertaken on continuous basis for optimal utilisation of unevenly distributed resources as well as to facilitate  power  transfer  from  surplus  to  deficit  regions  across  the  country.  In  the process, five regional grids namely Eastern Region (ER), North Eastern Region (NER), Western Region (WR), Northern Region (NR) and Southern Region (SR) were integrated in  a  progressive  manner through high capacity  High Voltage Direct Current (HVDC), 765 kV/400 kV inter-regional links. Integration of regional grids resulted in formation of One Nation - One Grid - One Frequency.

……….2.

(b) : Yes Sir.  One Nation - One Grid - One Frequency helps power sector and consumers to a great extent. It has facilitated power transfer from the resource rich areas to major load centers with reliability, security and economy. In addition, it has enabled  access  to  low  cost  power  as  well  as  development  of  vibrant  electricity market  with  significant  reduction  in  price  of  electricity  to  the  consumer.  Besides above, it is also facilitating integration of large scale variable renewable generation capacity in the grid.

(c) : The  present  cumulative  Inter-Regional  transmission  capacity  is  about 1,03,550 MW.

(d) : Strengthening/Augmentation of the National grid is a continuous process to meet the growing demand with reliability and security. In this direction, the InterRegional transmission capacity is also being enhanced. The cumulative inter-regional transmission  capacity  shall  be  enhanced  to  about  1,18,740  MW  in  next  2-3  years. Details  of  Inter-Regional  links  of  about  15000  MW  under  implementation  are  as follows:

(i)  Raigarh - Pugalur ±800 kV, 6000 MW HVDC Bipole

(ii)  Vindhyachal - Varanasi 765 kV D/c line

- (iii) Warora Pool - Warangal (New) 765 kV D/c line

(iv)  Loop  In  Loop  Out  (LILO)  of  Narendra  -  Narendra  (New)  400kV  (Quad)  line  at Xeldam (Goa)

- (v) Reconductoring of Siliguri - Bongaigaon 400kV D/c and Alipurduar -  Salakati 220 kV D/c lines with high capacity conductor.
