(SHRI  R.K. SINGH)

(a) & (b) : In  order  to  avoid  the  outage  in  the  electricity  grid,  the  Islanding  scheme  was reviewed  in  the  Ministry  of  Power  (MoP)  and  it  was  decided  that  islanding  schemes  may  be designed  for  all  major  cities  of  the  country  covering  the  essential  loads. All  the  five  Regional Power  Committees  (RPCs)  have  coordinated  with  the  States  and  have  identified  various  new islanding schemes.

(c) & (d) :     MoP, with assistance of Central Electricity Authority (CEA), has prepared a 'Crisis Management Plan' for addressing the manmade crisis situations such as terrorist attacks, cyberattacks,  bomb  threats,  strikes  etc.  Apart  from  basic  plan  that  encompasses  the  whole  power sector,  sector-specific  generic  documents  on  crisis  management  for  thermal,  hydro,  renewable, transmission  and  distribution  sectors  have  also  been  prepared.  All  such  plans  are  revised  on  a regular  basis  to  keep  it  abreast  with  the  new  challenges  and  issues  coming  up  with  changing times.

(e) & (f) :     While designing the Islanding schemes, States have been advised that the generating stations,  which  are  spatially  nearby  the  strategic  and  essential  loads,  may  be  given  priority. However, if there is a need to establish a power plant in/around such a city for the purpose, the proposal  may  be  submitted  for  consideration  of  the  concerned  State/Utility.  Possibility of installation of storage system at such location may also be explored.
