KUTTIADY OLD POWER STATION (KHEP) |
||||||||||

With an installed capacity of 75 MW (3 x 25MW) the Kuttiady Power Station was commissioned on 30.09.1972. The main macinery for the project are of M/s FUJI Electric Co. Ltd. Japan. Vertical Pelton turbine is used in the station. The firm annual generation capability of Kuttiyadi old power station is 268 MU The date of commissioning of the units are as below. | ||||||||||

KUTTIADY EXTENSION SCHEME ( KES) |
||||||||||

An additional 50 MW unit was installed as part of this scheme near to the old powerhouse, to avoid spillage and loss of generation potential from the reservoir during heavy monsoon. The firm annual generation capablity of the unit is 75 MU . The machine (named as Unit #4) is of GE Canada make and was commissioned on 27.01.2001. This unit also uses verical pelton turbine. | ||||||||||

KUTTIADY ADDITIONAL EXTENSION SCHEME ( KAES) |
||||||||||

The 100 MW (2 x 50 MW) Kuttiady Additional Extension Scheme was formed by construction of a new powerhouse building adjascent to the Kuttiady Extension Scheme. The project was envisaged as solution to the spill and consequent energy loss during intense monsoon . The firm annual generation capablity of KAES is 223 MU. A penstock of approximately 2 km length and a tunnel of 686m was additionally constructed for this scheme. The first unit was commissioned on 11.10.2010 and second unit on 30.10.2010, raising the installed capacity of the project to 225 MW. The project was executed by BHEL - L&T Consortium. The machines uses vertical pelton turbine. | ||||||||||
