TO BE ANSWERED ON 24.11.2016

## STORAGE TECHNOLOGY FOR RENEWABLE ENERGY

## *139.  SHRI K. ASHOK KUMAR

SHRI BIDYUT BARAN MAHATO:

Will the Minister of NEW AND RENEWABLE ENERGY be pleased to state:

- (a) the  electricity  generation  capacity  through  the  renewable  energy  sources  in  the country at present;
- (b) whether the country has adequate storage technology for renewable energy and if so, the details thereof;
- (c) whether the natural variations in wind and solar energy and lack of adequate storage facilities  result  in  loss/waste  of  15-20  per  cent  of  all  renewable  energy  generated  in  the country and if so, the details thereof;
- (d) whether  the  Government  is  considering  Lithium-ion  to  be  used  for  battery  storage technology for renewable sector and if so, the details thereof; and
- (e) the  steps  taken/being  taken  by  the  Government  to  develop  storage  technology  for renewable energy in the country?

## STATEMENT REFERRED TO IN REPLY TO PARTS(a),(b),(c),(d)&(e) OF THE LOK SABHA STARRED QUESTION NO. 139 FOR 24.11.2016

(a): As on 30.09.2016, the electricity generation capacity through the renewable energy sources in the country is 45917 MW.

(b): Lead Acid battery  storage technology  for  Renewable  Energy  is  already available  in  the  country  and  is  being  used  in  off-grid/grid  interactive  solar photovoltaic systems/projects as also in small wind generator-solar photovoltaic hybrid systems in the country. Little experience is available for other technologies such as Li-on and vanadium-redox flow batteries in the country.

(c): No loss/waste of renewable energy generated is reported in the country at present.

(d) : Among  the  all  available  options  such  as  Sodium  Sulphur,  Vanadium redox,  Zinc-air  batteries,  pumped-hydro,  compressed  air  etc.  for  renewable energy power generation projects, Lithium-ion battery storage technology is one the prominent options to meet the anticipated challenges of frequency variation, load leveling, load shifting congestion in transmission and distribution etc.

(e): To get experience and develop storage technology for renewable energy in the country, Ministry of New and Renewable Energy (MNRE) has sanctioned following Research & Development (R&D) projects in energy storage area in the country:

i. One MW electrical (3.5 MW) solar thermal power plant with 16 hours thermal storage  for  continuous  operation  at  Mount  Abu  (Thermal  cast  iron  cavity receiver with heat storage).

ii.  High Energy Density Thermal Energy Storage for Concentrated Solar Plant at RKDF University, Bhopal.

iii. Development of a Modular Central Receiver Concentrated Solar Power Plant for  Decentralized  Power  Generation  at  NISE,  Gurgaon  (Cylindrical  conical thermal heat storage).

iv.  Development  of  Solar  PV  and  wind  hybrid  power  plant  and  large  scale battery  storage  at  Kaza,  Himachal  Pradesh.  (one  MWh  various  technologies battery storage).

In addition to above, three more projects with aggregate energy storage capacity  of  8.424  MWh  by  Indian  Oil  Corporation  Ltd.  (IOCL),  Rajasthan Electronics  and  Instruments  Limited  (REIL)  and  Bharat  Heavy  Electrical Limited  (BHEL)  have  been  finalized  to demonstrate  energy  storage for supporting Renewable Generation in the country. Solar Energy Corporation of India (SECI) has also issued a request for selection (RfS) for 100MW of gridconnected solar PV projects with large-scale battery energy storage systems at Kadapa  Solar  Park,  Andhra  Pradesh  and  200MW  in  Pavagada  Solar  Park, Karnataka.
