LOCATION
Ideally on the left bank of Chambal River at Up Stream of Kota Barrage
The 220 KV GSS is within ½ Kms.
LAND
Land measuring approx. 250 hectares was required for the project in 1976
COAL Coal India limited supply coal from its coal producing subsidiaries BCCL, SECL & ECL through railway wagons
WATER The source of water for power station is reservoir formed by Kota Barrage on the Chambal River

8.Cooling System• In KSTPS hydrogen cooling system is employed for generator
cooling.• Hydrogen is used because of its superior cooling properties & low
density.• Thermal conductivity of H2 7.3 times of air.
• Seal oil system are used in turbine for less friction in bearing.• Water cooling also used for any kind of fire.
