Power plant with exhaust gas recirculation compressor

A power plant comprising:

• a gas turbine engine comprising a compressor having a compressor outlet, the gas turbine engine further comprising a turbine configured to discharge a first exhaust gas stream therefrom;
• a heat recovery steam generator configured to:
• extract heat from the first exhaust gas stream;
• and
• discharge a second exhaust gas stream and a steam stream therefrom;
• a cooler configured to cool the second exhaust gas stream, thereby defining a cooled exhaust gas stream, wherein the cooler discharges the cooled exhaust gas stream;
• an exhaust gas recirculation line configured to channel a first cooled stream portion of the cooled exhaust gas stream towards the compressor;
• a recirculation compressor configured to selectively pressurize the first cooled stream portion of the cooled exhaust gas stream for discharge to the compressor outlet;
• a steam turbine configured to:
• receive a first stream portion of the steam stream therein;
• and
• discharge a first extraction flow;
• and
• a carbon capture system configured to receive the first extraction flow and a second cooled stream portion of the cooled exhaust gas stream.
