Situated in West Kameng District of Arunachal Pradesh, the Kameng H.E. Project (600 MW) is a run-of-the river scheme which will utilize the flows from Bichom and Tenga Rivers (both tributaries of the River Kameng) over a gross head of 536 m available in downstream of the confluence of the River Bichom with Kameng. The Project comprises of two Nos of Dams viz. Bichom & Tenga and water is transported through a Head Race Tunnel (HRT) & HPT / Penstock into the Kimi Power House for driving 4 Nos. of Vertical Frances Turbines,150 MW each. The design energy of the Project is 3353 MU in 90% dependable year with 95% Machine availability.
CCEA clearance of the Project was obtained in December 2004 at Rs 2496.90 Crs with a time of completion of 5 years. However owing to a range of factors, beyond the control of NEEPCO viz.major design change of primary structures, geological surprises, devastatingflash floods, contractual issues, law and order problems etc., the commissioning of the Project has been delayed and now anticipated for commissioning in January 2018. Due to this time over-run, the Project Cost has also gone up and the Revised Cost Estimate (RCE) of the Project has been appraised at Rs. 6179.96 crs at March ’15 PL by CEA.
