b) PROJECT PERSPECTIVE:

River Bhogavati, a tributary of Panchganga river rises in the Western Ghats of Sahyadri Ranges in Kolhapur District. Panchganga is one of the major tributary of Krishna river. The Dam constructed and strengthened with downstream buttresses, across Bhogavati river is masonary surki mortar dam of height 42.68 m with live storage of 236.79 Mcum. Water stored thus, is released through irrigation outlet directly into Bhogavati river to fill the downstream series of  K.T. weirs for irrigation. The dam has been constructed long back i.e. in 1954 across river Bhogavati at village Fejiwade, Tal-Radhanagari, Dist-Kolhapur

Automatic floodgates have been provided on left flank waste weir , which cascade down on hard exposed rock and meets original river course. There are 5 numbers of under sluices of size 2.44m X 5.7m each on left flank in saddle having a discharge capacity of 40000 cusecs. Normally the maximum discharge required for irrigation is 1400 cusecs; whereas each river sluice has discharging capacity of 8000 cusecs.

Water stored is let down in the river and further picked up downstream at series of weirs from where irrigation potential is served.

    2.1         PRESENT POSITION AND CHANGES PLANNED FOR HEAD WORKS:

It is proposed to convert existing two numbers of under sluices ( size 2.44m x 5.71m) into power outlet and suitable size steel lining with baffle on emerging out of dam connecting to penstocks in

the body of dam upto upstream face of power house, to feed water to two ( 2 Nos) Turbine Generating units of requisite capacity with main inlet valve in the power house building. It is proposed to generate power from the irrigation releases from Radhanagari dam utilizing the variable head.  Power House is proposed to be located at the toe of dam on right side plateau of under sluice canal. Tail water will be guided through a small length letting into the river. Each steel penstock of 3.25m diameter and 12mm thickness is designed to carry a peak discharge of 26.00 cumecs. Other under sluices will be used as bypass during closure of the unit to release discharge into the river, for downstream irrigation. Discharge capacity of three sluices will be 24000 cusecs, which is much more than irrigation need.

2.2        POWER POTENTIAL:

Head fluctuations are susceptible at the site and varies from about 35.00 m to 18.00 m and more of which is not economically usable during a small period of June i.e. about 8 days is available for power generation and July to April of each year are fully available for energy production. This resource has good renewable potential of about 27 Mus per annum. Studies show, to explore complete range, Francis set could be installed at the site. To achieve better flexibility 2 units each of 5000 kW totaling to 10000 kW could be installed to cover up energy generation limit as set by GOMWRD. 75% reliable annual generation works out to as indicated by GOMWRD as 26.83 Mus. 

The hydro scheme is basically planned as a small energy feeding station.

 2.3            GEOLOGICAL CONDITION AT SITE:

The site has earlier geological studies conducted for Radhanagari dam. Exposed rock is available in the riverbed and nearby areas. From trial pit observations, it is seen that a good foundation is available for powerhouse location. In addition, hard rock is expected about 3 to 5m below over burden in power block zone.

The powerhouse is proposed on D/S of buttresses constructed for strengthening of the dam.

2.4            INTENT Of THE TENDER :                                                                                                                                        Intent of the tender is to : Design, Manufacture, Test at Shop, Supply at site including Transport, handling, loading/unloading, Supervision during Erection, Testing, Commissioning and Setting to Operation of Turbine/Generator sets for Radhanagri Hydro Electric Project:
