The 720MW Mangdechhu hy­dropower project will be com­mis­sioned be­gin­ning 2019.

As of Oc­to­ber 31, 2018, 98.99% of the over­all phys­i­cal progress of the project was achieved; 93.98% of the over­all fi­nan­cial progress with re­spect to the third re­vi­sion cost es­ti­mate un­der ap­proval from the Gov­ern­ment of In­dia and 98.82% over­all fi­nan­cial progress with re­spect to the sec­ond re­vi­sion cost es­ti­mate.

Man­ag­ing Di­rec­tor of Mangdechhu Hy­dropower Project AK Mishra said the Mangdechhu project is in an ad­vanced stage of com­ple­tion and sta­tus of var­i­ous civil, elec­tro-me­chan­i­cals, hy­dro-me­chan­i­cal and trans­mis­sion lines and its ATS are near­ing com­ple­tion.

More than 99.8% of phys­i­cal progress on dam works has been made, 99.79% on head­race tun­nel work and 98.89% on un­der­ground power house works, 98.3% on hy­drome­chan­i­cal works, 95.8% on elec­tro-me­chan­i­cal works and trans­mis­sion line and 100% ATS works.

AK Mishra said the MHPA man­age­ment is plan­ning to start fill­ing the wa­ter con­duc­tor sys­tem or the head­race tun­nel and pres­sure shafts from De­cem­ber 20, 2018 on­wards along with plug­ging of di­ver­sion tun­nel.

He also said that unit-1 shall be spun ei­ther on De­cem­ber 30 or 31 this year. Syn­chro­niza­tion of the first unit within In­dian Grid shall take place in the first 10 days of Jan­uary 2019.

“The full com­mis­sion­ing of all the four ma­chines is sched­uled by end of Jan­uary and be­gin­ning of Fe­bru­ary next year,” said AK Mishra.

Mangdechhu project will ex­port 3bn units ev­ery year to In­dia.

He said the project tar­iff is un­der dis­cus­sion be­tween the Gov­ern­ment of In­dia and the Royal Gov­ern­ment of Bhutan.

The to­tal ex­pen­di­ture in­curred as of Oc­to­ber 31 this year in­clud­ing ad­vances is around Nu 46bn and ex­pen­di­ture in­curred from ma­jor con­tract for dam, head­race tun­nel, un­der­ground pow­er­house, hy­dro-me­chan­i­cal, elec­tro-me­chan­i­cal and trans­mis­sion lines and its ATS is around Nu 37bn.

Ma­jor ex­pen­di­ture was made on con­struc­tion of the dam amount­ing to Nu 9bn as of Oc­to­ber 31, 2018.

The first re­vised cost es­ti­mate of Nu 40.2bn at 2014 price level was ap­proved by the Gov­ern­ment of In­dia, which is an in­crease of Nu 11,24bn from the ini­tial ap­proved cost of Nu 28.96bn at March 2008 price level. The sec­ond re­vised cost es­ti­mate in 2016 price level was Nu 46.72bn.

The project com­menced its con­struc­tion in Au­gust 2010.
