800 MW GE / Alstom Combined Cycle Gas Turbine
50 Hz Power Plant operates on Natural Gas Re:25937

25937

This is an 810 MW (2 x 405 MW, ISO) Combined Cycle Power Plant comprised of two (2) identical streams of 1+1+1 configuration.

Each stream has one 9FA Gas turbine from GE/USA, one Steam Turbine Generator from Alstom/Germany & one HRSG along with associated auxiliaries & the balance of equipment which fully equips a complete Plant.

The plant was commissioned in Oct 2015 and is currently not in operation as there is no gas supply. It is currently under preservation as per OEM norms.

Periodic maintenance and technical support for the Gas and Steam Turbines is on going and all plant and equipment will receive warranties and guarantees for performance from the respective OEM’s.
