## LOK SABHA UNSTARRED  QUESTION NO. 2363

TO BE ANSWERED ON 16.03.2017

## TRANSMISSION PROJECTS

## 2363.   DR. K. GOPAL:

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

- (a) whether the transmission projects worth Rs. 50,000 crore would be up for bids during this financial year in order to boost capacity of renewable energy and if so, details thereof;
- (b) whether  the  increasing  share  of  renewable  energy  in  the  overall  energy  mix  in  the country will have significant implications for the national grid and will go upto 40 per cent by 2030 and if so, the details thereof; and
- (c) whether this will throw a huge challenge to the grid operations and if so, the details thereof and the steps proposed to be taken thereon?

## ANSWER

## THE  MINISTER  OF  STATE  FOR  POWER,  COAL,  NEW  &  RENEWABLE  ENERGY AND MINES (INDEPENDENT CHARGE) (SHRI PIYUSH GOYAL)

- (a): No Madam.  Under Green Energy Corridor transmission projects, Rs.5049.72 crore and  Rs.  11369  crore  have  been  bidded  out  under  intra-state  and  inter-  state  components respectively.(Annexure-I & II)
- (b): No Madam.  Share of renewable energy in overall energy mix of the country is not targeted  to  go  up  to  40%  by  2030.  The  Intended  Nationally  Determined  Contributions  of India  aim  to  achieve  about  40%  cumulative  installed  capacity  from  non-fossil  fuel  based energy resources by 2030.
- (c): Large  scale  integration  of  renewable  energy  into  the  grid  will  be  a  challenging situation  due  to  intermittent  nature  of  wind  and  solar.    To  meet  such  challenge,  following steps are being taken:
- (i) Development of Green Energy Corridor.
- (ii) Notification of Forecasting and Scheduling of Regulations by CERC and SERCs.
- (iii) Amendment of Regulations for Technical Standards for Grid Connectivity.
- (iv) Development of Renewable Energy Management Centres.
- (v) Installation of Availability Based Tariff meters.
