Alchi Hydroelectric Power Plant

The Nimoo Bazgo power project is a run-of-the-river power project on the Indus River situated at village Alchi, 70 kilometers from Leh in the Indian state of Jammu and Kashmir. The project was conceived on July 1, 2001 and approved on June 8, 2005, and construction began on June 9, 2005. The project involves construction of a 57-metre (187 ft)-high concrete dam with five spillway blocks of 13 metres (43 ft) each having ogee profile.

The Nimoo Bazgo power project envisages utilizing a rated net head of 34 metres (112 ft) to generate 239.30 gigawatt-hours (861.5 TJ) (million units) in a 90% dependable year. The project has three surface power units of 15 megawatts (20,000 hp) each with an total installed capacity of 15 megawatts (20,000 hp). Every unit has a 3.3 m dia, each 63 m long Penstocks. Each operating unit will be designed for a discharge of 48.7 cubic metres per second (1,720 cu ft/s) and also have transformer yard and switch yard. The project will be connected to the northern grid through a 220 kV transmission line from Leh to Srinagar (the line is scheduled for commissioning with project commissioning). The dam diverts water from the river by a 372 metres (1,220 ft) long diversion channel and involves a flooding of only 3.42 km². Thus the power density is 45 MW per 3.42 km², i.e. 13.16 W/m². The project is being developed by National Hydroelectric Power Corporation (NHPC) Ltd., while Bharat Heavy Electricals Ltd. (BHEL) has executed the Electro-Mechanical works.

All the three units of the project have been successfully commissioned. The project was inaugurated on 12th August 2014 by the Prime Minister of India Narendra Modi, in a ceremony attended by senior officials including Chief Minister of Jammu & Kashmir Omar Abdullah, National Security Adviser Ajit Kumar Doval and others.[1]
