A power plant system includes a set of gas turbines with a first gas turbine and a second gas turbine operating. The first gas turbine and the second gas turbine are configured to generate energy. The power plant system includes a first OTC unit associated with the first gas turbine, where steam is supplied from the first OTC unit. The power plant system includes a second OTC unit associated with the second gas turbine, where steam is supplied from the second OTC unit. Further, the power plant system includes a HRSG unit associated with a second gas turbine, where the steam is supplied to the HRSG unit from the first OTC unit and the second OTC unit to generate specific steam. The power plant system includes a set of steam turbines generates energy based on a supply of the specific steam from the HRSG unit to the set of steam turbines.
