| Project Features:
Saundatti PSP is located Belagavi district of Karnataka. It envisages creation of upper reservoir, water conducting systems, power house & lower reservoir near Karlakatti village. The scheme will involve construction of 4605 m long Geomembrane faced rockfill embankment dam for creation of upper reservoir of 0.735 TMC gross capacity. The Lower reservoir with 0.706 TMC gross capacity. The scheme envisages utilization of 193.35 m rated head and design discharge of 190.56 Cumecs for generation of 1280MW (4 units of 320 MW each) and 193.08 m rated head and design discharge of 95.81 Cumecs for generation of 320MW (2 units of 160 MW each).
The major project components are:
-
- Geomembrane faced Rockfill embankment with height in the range varying between 10m and 38m. for creation of Saundatti upper reservoir with 0.735 TMC gross storage capacity.
- Intake Structure.
- Water Conductor system, 4 nos. of 1060.60 m long and 7.1m dia. circular steel lined Penstock / Pressure Shaft (i.e., consisting of 263.15m long Surface Penstock, 244.19m long Vertical Pressure Shaft and 553.26 m long Horizontal pressure shaft up to powerhouse) to feed 4 nos. 320MW unit each. Similarly, One no. of 951.30 m long 7.1m dia. circular steel lined Penstock /Pressure Shaft (i.e., consisting of 259.72m long Surface Penstock, 243.33 m long Vertical Pressure Shaft and 448.25 m long Horizontal pressure shaft up to bifurcation point) which will get bifurcated into 2 nos. near powerhouse each of 77.65m long and 5.0m dia. to feed 2 nos. of 160 MW unit each.
- A surface Power house having an installation of four nos. reversible Francis turbine each of 320 MW capacity (All units are fixed speed turbines) operating under a rated head of 193.35 m in generating mode & 202.78 m in pumping mode and two nos. reversible Francis turbine each of 160 MW capacity (both units are fixed speed turbines) operating under a rated head of 193.08 m in generating mode & 202.88 m in pumping mode.
- Six numbers of 255.44m long tail race tunnel connecting the tail race outlet structure and the draft tube of the power house out of which four larger units has a tunnel dia of 8.0 m whereas two small units consists of 6.65 m dia.
- Tailrace Outlet structure.
- Geomembrane faced Rockfill embankment with height in the range varying between 10m and 24 m for creation of Saundatti lower reservoir with 0.706 TMC gross storage capacity.
