## DEPENDENCE ON COAL

3742.  DR. UDIT RAJ:

Will the Minister of POWER be pleased to state:

- (a) whether  the  country's  power  generation  over  the  next  few  decades  will continue to depend heavily on coal and if so, the details thereof;
- (b) whether  an  advanced  ultra  super  critical  technology  project  has  been approved by Government for coal based power plants; and
- (c) if  so,  the  objectives  and  the  progress  made  in  implementation  of  the project?

## A N S W E R

THE MINISTER OF STATE (INDEPENDENT CHARGE) FOR POWER AND NEW & RENEWABLE ENERGY

( SHRI  R. K. SINGH )

(a) : As per National Electricity Plan, 2018, all India coal based generation by the year 2021-22 is estimated to be around 63% of the total energy generated from all sources. Similarly,  by  the  year  2026-27,  all  India  coal  based generation is estimated to be around 55.7% of the total energy generation. Thus, country's  power  generation  over  next  decade  will  continue  to  depend  on  coal based generation.

(b) & (c) : The  Goverernment  has  approved  the  Research  and  Development (R&D) Project (Phase-I) for development of Advanced Ultra Super Critical (AUSC) technology for Thermal Power Plants.

The  objective  of  the  R&D  project  is  to  develop  coal  fired  power plants  with  Advanced  Ultra  Supercritical  Technology  (AUSC)  for  800  MW  with targeted efficiency of about 46%.

Phase-I  of    the  R&D  project  is  being  executed  by  a  consortium comprising  of  Indira  Gandhi  Centre  for  Atomic  Research  (IGCAR),  NTPC  and  BHEL under  the  Chairmanship  of  Principal  Scientific  Advisor  (PSA)  to  the  Government.  A dedicated Mission Directorate has been established to co-ordinate the R&D activities. Phase-II  of  R&D  project  envisages  installation  of  an  800  MW  AUSC  Technology Demonstration Plant based on the technology developed under phase-I.

The status of progress made in implementation of the milestones for Advanced Ultra supercritical R&D Project is given at Annex.  On completion of the R&D project,  800  MW  capacity  demonstration  plant  will  be  set  up  by  NTPC  at  the existing Sipat site.
