Project Detail

 

86 MW, Run-of-River, commissioned 2001. Annual production of 350 GWh, Net head is 600 m and discharge is 26 m3/s. Malana HPP have four desilting basins, a 249 000 m3 storage reservoir and a 3.3 km long. Headrace tunnel. 2 vertical shaft Pelton turbines.

Implementation: SediCon supplied a SediCon Dredge, allowing sediment removal without input of power, by using a hydrosuction system. The SediCon Dredge was implemented during monsoon season 2005.

Results: During two months in the summer of 2005, 36 000 m3 sediments were removed from the storage reservoir. As sediments were removed only during monsoon, when excess water is available, no water was taken from production.
