## POWER SUPPLY TO NATIONAL GRID

3184. SHRI JASHUBHAI BHILUBHAI RATHVA:

Will the Minister of POWER be pleased to state:

- (a) the current total installed power generation capacity in the country along with the latest available figures indicating the respective shares of fossil fuel-based and nonfossil fuel-based sources;
- (b) the portion of this installed capacity that is presently generation-ready and capable of supplying power to the national grid together with the criteria used to determine gridreadiness;
- (c) whether the quantum of installed generation capacity remains unutilised or underutilised  due  to  the  absence  or  inadequacy  of  transmission  infrastructure,  if  so,  the details thereof, State wise; and
- (d)  the  timelines  proposed  by  the  Government  for  completing  the  transmission infrastructure  necessary  to  ensure  timely  evacuation,  grid  integration  and  optimal utilisation of power across all regions of the country?

## A N S W E R

THE MINISTER OF STATE IN THE MINISTRY OF POWER

(SHRI SHRIPAD NAIK)

(a) & (b): The  total  installed  power  generation  capacity  in  the  country  stands  at 5,05,023 MW, comprising 2,45,600 MW from fossil fuel sources and 2,59,423 MW from non-fossil  fuel-based  sources.  The  installed  capacity  has  been  commissioned  in accordance  with  applicable  technical  standards,  is  grid-connected  and  generation ready.  It  is  capable  of  injecting  power  into  the  National  Grid,  subject  to  prevailing system  conditions.  Details  of  electricity  generated  from  various  sources  during  the period from April, 2025 to October, 2025 are given in the table below:

| Category        | Installed Capacity (in MW)   | % Share in Installed Capacity   | Electricity Generated (April, 2025 to October, 2025) (in MU)   | % Share in Total of Generation   |
|-----------------|------------------------------|---------------------------------|----------------------------------------------------------------|----------------------------------|
| Fossil Fuel     | 2,45,600                     | 48.6%                           | 7,52,583                                                       | 68.2%                            |
| Non-Fossil Fuel | 2,59,423                     | 51.4%                           | 3,51,405                                                       | 31.8%                            |
| Total           | 5,05,023                     | 100%                            | 11,03,988                                                      | 100%                             |

………2.

(c) : The National Transmission Grid has been remained accommodative in integrating generation capacity, including large - scale Renewable Energy (RE). There has been no curtailment of generation capacity with effective General Access Network (GNA) to the Inter-State  Transmission  System  (ISTS).  However,  at  present,  temporary  GNA  for evacuation of 12,407 MW of power has been provided through the available margins on the existing ISTS, subject to technical and operational constraints across different time blocks. Of this, 5,370 MW is located in Gujarat, 4,088 MW in Rajasthan, and 2,949 MW in Karnataka/ Tamil Nadu.

(d) : Transmission systems associated with generation projects are planned well in advance and implemented in a phase manner, aligned with projected capacity addition. The  National  Grid  is  being  strengthened  on  a  continuous  basis  to  ensure  timely evacuation, grid integration and optimal utilisation of power across regions. Presently, 234 Inter-State Transmission System projects, capable of evacuating about 203 GW of generating capacity, are under various stages of implementation and are planned to be commissioned progressively by 2031.
