Kalpong Hydroelectricity Project
Kalighat, Diglipur, North Andaman
The Kalpong hydro electricity project was built with a desire to use natural resources for power generation. Kalpong River, which is said to be the only large river in the islands, springs in the slopes of the Saddle Peak Natural Park, traverses in the northward direction for a length of about 35km before it joins the Aerial Bay Creek on the east coast. This project uses this available water resources to generate about 14.83 million units of energy per year and provide 5.25 MW of additional capacity in the power system of the region. The whole project has made a major shift in the source of power generation in North and Middle Andaman from the costly and polluting diesel-driven generating sets to the eco-friendlier hydroelectricity.
The Hydro-Electric Power Project is worth stopping by during your trip to Ram Nagar beach or Alfred caves. There are two dams to be visited; one is 34m high and 138m long concrete dam on the left fork of the river and the other is 27m high and 146m long rock-fill dam on the right fork. There is also a 300m long link channel, a 133m long tunnel, 3 numbers penstocks, a powerhouse with three units of 1.75 mw each and a switchyard.
