Details: Reviews 1


The CCPP plant is a 810 MW (2 x 405 MW, ISO), combined cycle power plant.

The project comprises of 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 and one HRSG built by L&T along with associated auxiliaries and balance of plant.

The plant is designed to operate on Natural Gas.

The plant generation is at 15.75 KV stepped up to 400 KV for synchronization to the grid.

The plant was constructed by L & T

The plant was commissioned in Oct 2015 and is not in operation as there is no gas

supply. It is currently under preservation as per OEM norms ( GE, Alstom , L&T).

The units can be relocated at a suitable location within a period of approx. 24 months.

Owners had signed a Long Term Service and Parts Supply Agreement with GE for the

Periodic maintenance and technical support for the Gas Turbines. They will also provide

services for maintenance and spares supply for the Steam Turbines.

All plant and equipment will get warranties and guarantees for performance from respective OEM’s.
