KALPONG
The Andaman and Nicobar Islands is presently meeting its power requirements through diesel generating sets for which diesel is transported from the mainland over a distance of 1200 km by sea.
The Kalpong HE Project ( 5.25MW) is the First Hydro-Electric Power Plant , executed and Commissioned by NHPC for and behalf of A&N Administration on Deposit Work basis in this islands now marks a major shift in the source of power generation at least in North Andaman from costly and polluting diesel driven generating sets to the cleaner hydro-electricity. The project is providing annual energy contribution to the tune of 14.83 MU and thus saving around 5000 KL of HSD oil annually which shall result in annual saving of around Rs.10.00 crore on account of Diesel only.
The project utilises waters of both the left and right forks of the Kalpong river in North Andaman by constructing a 34 M high Concrete Dam on the left and 27 M high Rock fill Dam on the right fork. A link channel connects both the left fork and right fork reservoirs. An approach channel carry water from the main reservoir (left fork) to the intake for further conveying it to the Power House through 133 M long tunnel and then through 650 M long steel buried penstock pipes, supported on 11 nos Anchor Blocks.
The Project was Commissioned on 1.9.2001 , 14 months ahead of Schedule and Handed Over to the A&N Administration w.e.f. 1.6.2002 after 9 months of Successful running and maintenance.
