The first contract covers the retrofitting of the turbine island equipment on the six units, while under the second contract Alstom will retrofit the units’ existing electrostatic precipitators.
Alstom will engineer, supply and install high pressure and intermediate pressure turbines, associated auxiliaries, turbine controller, bypass systems, heater refurbishment, instrumentation and control (I&C), and integration engineering coupled with installation supervision.
When completed, the retrofit will increase each of the six units’ power generating capacity by 20MW, bringing a total capacity increase of 120MW.
The project will boost cycle efficiency by 2.4%, thereby reducing the specific CO2 emissions by about 600,000 tons per year, Alstom said.
