The Chutak Hydroelectric Plant is a run-of-the-river power project on the Suru River (a tributary of Indus) in Kargil district in the Indian state of Jammu and Kashmir (224 km (139 mi) from the state's summer capital Srinagar). The barrage of the project is at Sarze village and the powerhouse is located on the right bank of the Suru near Chutak Village. The project construction began on September 23, 2006, and the first three generators were commissioned in November 2012. The fourth was commissioned in January 2013.[1]

The project includes construction of a 47.5-metre-long (156 ft) barrage, having 15 m height above the crest level, an underground powerhouse, and 3.3 m dia and 10.02 km long head race tunnel and installation of four nos. of vertical Francis turbine of 11 MW each. The project envisages utilizing a gross head of 63.4 m (208 ft) to generate 216.41 GWh in a 90% dependable year with an installed capacity of 44 MW. Each 11 MW underground generating unit will operate under a rated head of 52 m and a rated discharge of 24.05 cubic metres per second. The barrage diverts water from the river and involves a flooding of only 0.135 km2 (0.052 sq mi). Thus the power density is 44 MW per 0.135 km2, i.e. very high 326 W/m2, compared to dam-based hydroelectric projects. The project will be connected to the Northern Grid by the 220 kV Leh-Srinagar transmission line, which is to be scheduled for commissioning along with project’s commissioning.[2]

The project is being developed by M/s National Hydroelectric Power Corporation Ltd. The generating equipment is being supplied, erected and commissioned by M/s Bharat Heavy Electricals Limited. The generator/turbine was manufactured by BHEL's Bhopal unit whereas the controls were supplied by BHEL's Bangalore unit. The erection and commissioning is being done by BHEL's Power Sector Northern Region under able guidance of Narendra Kumar (GM Hydro-BHEL). As of date all four generating units of this project are running successfully.
