L&T Uttaranchal Hydropower Limited (L&T UHL) is implementing the 99 MW run-of-the-river Singoli-Bhatwari Hydroelectric Project in Uttarakhand. The project was awarded in 2006 on Build, Own, Operate and Transfer (BOOT) basis, after a competitive bidding process by Government of Uttarakhand (GOU). L&T UHL signed the Implementation Agreement with GOU in November 2009.
The project is located on Mandakini River, the right bank tributary of Alaknanda River, in the Garhwal region in Rudraprayag district in Uttarakhand, India. The proposed barrage site is 4 km downstream at the confluence of Mandakini River with Madhyamaheshwar River, near Singoli village. The power generating units would be located near Phalai village in a surface Power House located about 15 kms further downstream on the right bank of Mandakini River.
The Power House of the project is at a distance of 400 kms from Delhi, 165 kms from Rishikesh and about 25 kms from Rudraprayag.
The project involves construction of a 22 m high barrage, 11.26 km long head race tunnel of 4.9 m diameter, an orifice type surge tank, steel-lined pressure shaft and a surface powerhouse. Three Francis turbines of 33 MW each located inside the surface Power House will be used to generate 472.18 million units of energy in a 90% dependable year.
The project has obtained all clearances and has achieved financial closure. All construction contracts executed and construction is in progress.
