The highest point in the Andaman Islands is the 750 metre high Saddle Peak in North Andaman and traverses in a northerly direction for a total length of 35 km before merging into the sea near the Aerial Bay on the eastern coast. The Kalpong Hydroelectric Power Project is located at this point. Prior to its commissioning by the NHPC in September 2001, the islands were meeting their power requirements from diesel generating sets which were causing environmental and noise pollution.
