A power house at the foot of the Mani dam on the right bank utilises the reservoir head and generates about 40 MU of energy annually. Two Penstocks of 2.5 mtrs in diameter embedded in the dam feed the two vertical axis Kaplan turbines coupled to the 4.5 MW generators.. The design head of the units is 22.5 mtrs and units operate for a head variation of 11.25 mtrs to 33.75 mtrs.
