( SHRI  R. K. SINGH )

(a) : As per reassessment studies, carried out by Central Electricity Authority (CEA) during 1978-1987, the hydro power potential from major / medium schemes (above 25 MW capacity) is 145320 MW.  The total hydro power  generation  capacity  in  the  country,  including  pumped  storage scheme (above 25 MW capacity) as on 30.06.2018, is 45315.22 MW.

(b) : The work for reassessment of earlier assessed Hydro Electric Potential has been taken up by CEA in association with WAPCOS Ltd. (a public  sector  undertaking  under  Ministry  of  Water  Resources,  River Development & Ganga Rejuvenation), in March, 2017.

...........2.

(c) : The total Hydro Power Generation in the country [from Hydro Electric Projects (HEPs) above 25 MW capacity] during the year 2017-18 is 126122.70  Million Units (MUs)  and  in 2018-19  (upto 30.06.2018) is 31457.85 MUs. State-wise generation in respect of Hydro Electric Projects above 25 MW capacity is given at Annex-I.

(d) to (f) : As on 30.06.2018, 38 Hydro Electric Projects (above 25 MW) aggregating to 12208.50 MW are under construction in the Country and a total amount of Rs. 56,913.42 crs. has been spent on these projects. Out of these, 35 HEPs aggregating to 11023.50 MW are delayed due to various reasons. The details of these projects are at Annex-II.
