Both capture plants treat flue gas from NGCC power plants containing around 6 wt % (4 mol %) CO 2 . The NGCC unit at each plant comprises two combustion turbines, two heat recovery steam generators (HRSGs), and one steam turbine, with flue gas diverted from the two HRSG stacks to the capture unit. The Panda NGCC unit has a maximum net output of 719 MW compared to 464 MW at the Mustang Station NGCC unit.
