The first unit of the 111 MW Sawra Kuddu Hydro Electric Project will start generating power by this April. The process of filling the head race tunnel of the project will start soon.
Water will be made available at the main inlet valve of the project power house by March. Execution of the project started in June 2007 but ran into trouble over the excavation of the 11.365 km head race tunnel because of adverse geological rock conditions. The project comprises a diversion barrage on Pabbar river near Hatkoti and underground powerhouse on th per cente left bank of the Pabbar river near Snail village.
Addressing mediapersons at Hatkoti on Thursday, Himachal Pradesh Power Corporation Limited director (Civil) D S Thakur said despite adverse geological conditions encountered during the excavation of the head race tunnel, the project had to be driven through rock strata with high ingress of water along with flowing rock conditions at various locations. He said it had to be tackled very cautiously and with high engineering proficiency.
According to Thakur, work on the barrage was awarded to Patel Construction Company and the head race tunnel was initially awarded to Aban Coastal joint venture in June 2007. The barrage was completed on time but poor performance of Aban Coastal joint venture led to termination of the contract in January 2014. Balance works were subsequently awarded to Hindustan Construction Company Limited in November 2014.
The project will generate 386 million units per annum, earning a revenue of Rs 115 crore for the state government. It has 11.365 km long, 5 m finished diameter head race tunnel (HRT) and three 37 MW Francis Turbines (3 X 37 MW).
After being commissioned, each family affected by the project will be provided with 100 units of electricity per month for a period of 10 years.
