1643.  SHRI SELVAGANAPATHI T.M.:

Will the Minister of POWER be pleased to state:

- (a) whether  it  is  a  fact  that  the  Central  Electricity  Regulatory  Commission  has appointed a single-member bench to look into aspects relating to the preparedness of  power  managers  and  other  stakeholders  to  meet  the  challenges  arising  on account of the sudden surge in power demand and if so, the details thereof;
- (b) whether it is also a fact that the peak power demand is expected to be 232.2 GW and if so, the steps taken/being taken by the Government in this regard;
- (c) whether it is also true that there is an additional  requirement  of  generating resources of about 12.60 GW with a reserve requirement of 3% to meet contingency and if so, the details thereof along with the steps taken by the Government;
- (d) whether it is also true that the said Commission directed the National Load Dispatch Centre, Regional Load Dispatch Centres (RLDCs), and State Load Dispatch Centres  (SLDCs)  to  submit  a  report  on  the  implementation  of  steps  as  per  the provisions of the Grid Code; and

## THE MINISTER OF STATE IN THE MINISTRY OF POWER

(SHRI SHRIPAD NAIK)

- (a) : Yes.  Central  Electricity  Regulatory  Commission  (CERC)  in  Suo  Motu  Petition No.  9/SM/2024  has  appointed  a  Single  Member  Bench  on  07.10.2024  to  look  into aspects relating to the preparedness of system operators and other stakeholders to meet the challenges arising on account of the sudden surge in demand for power due to  seasonal  variations  and  give  recommendations  with  regard  to  the  remedial measures to be taken for the future.
- (b) & (c) : As per the submission made by NLDC/Grid-India to CERC in the Petition No. 9/SM/2024, the peak  power  demand was forecasted to reach  232.2 GW in October 2024  with  the  additional  generation  requirement  of  about  12.60  GW  (with  3% reserve).

The following major steps have been taken by Govt. of India for meeting the increasing electricity demand in the country: (a) Directions under Section 11 of Electricity  Act have been issued to imported coal based plants to operate and generate power to their full capacity. (b) Gas based power plants of NTPC as  well as gas-based generation procured through NVVN are being scheduled during high power demand period. (c) Steady  supply  of  coal  to  all  the  thermal  power  plants  is  being  ensured  to prevent fuel shortages. (d) All  the  GENCOs  including  IPPs  and  Central  generating  stations  have  been advised to generate and maintain full availability on daily basis excluding the period of planned maintenance or forced outage. (e) Hydro  based  generation  is  being  scheduled  in  a  manner  so  as  to  conserve water for meeting demand during peak period. (f) Planned maintenance of generating units is being minimized during period of high demand. (g)  To meet the growing electricity demand, new power generation capacity was monitored closely for timely addition. (h)  All the States/ plants were instructed to offer any surplus generation into the market for better availability for the deficit States. However, All India Maximum Demand in the month of October, 2024 was 219 GW which was met without any shortages. (d)  &  (e):  Yes.  Under  directions  of  CERC,  the  NLDC  and  RLDCs  have  submitted reports highlighting the activities in various time horizons as per detail at Annexure.
