The Rengali masonry-cum-concrete dam, 1,040 M long has been divided into 51 blocks for construction purposes. Of these, 24 blocks in the centre are spillway blocks provided with radial gates and a spillway bridge. There are 8 non-overflow blocks in the right flank and 19 in the left. Blocks 10 to 14 from the left are power dam blocks through which penstock pipes of 6 meter dia are embedded. The power house is located just downstream of the Power Dam. This dam connecting two hill ranges on either side along with a 4.6 M high dyke near village Khindo forms the reservoir of 414 Sq. Km at M.W.L. of 125.4 M.

The power house accommodates the service bay and 5 unit bays for installation of 50 MW capacity generators in each unit.

For power generation axial flow kaplan turbines with 8 blades having runners of 4.5 M dia rotating at a speed of 166.7 RPM at the designed head of 40 M to produce a rated output of 50 MW are provided.

The construction of main dam had been completed in 1985.

For utilising the water discharge of power house for irrigation purpose, a barrage with 2 canals is under construction at Samal, located about 45 Km downstream of Rengali Dam.
