are the original planners and designers of the
Narayanpur-Tamankal cascade development.
The Narayanpur Dam is a balancing reservoir located on Krishna river downstream of the main storage at Almatti
Dam. From Narayanpur Dam, the main canals take off for providing irrigation to the vast lands of
Bijapur district. Downstream of Narayanpur Dam, the Krishna river flows for a distance of 50km in Karnataka
state before it enters Andhra Pradesh.
A proposal was conceived by the state utility Karnataka Power Corporation for the development of this stretch
of the river by diverting the flows at Narayanpur into a 70km long power canal
designed to carry 800 cumecs discharge to an underground power house with
an installed capacity of 1000 MW at Lingsugur.
The construction period was in excess of 10 years. The proposed power canal is
equivalent to constructing a river for 70km to divert the Krishna river flow to
the power house.
SECSD were instated by Energy
Secretary of Karnataka to examine whether an alternative to develop the hydropower potential of this
stretch was possible so as to make the project suitable for IPPs.
