Abstract: A system and method for reduction of diluent gaseous nitrogen (DGAN) compressor power in combined cycle power plant. A vapor absorption chiller (VAC) may be utilized to generate and transmit cooled fluid, such as water, to one or more heat exchangers located upstream and/or downstream of at least one compressor of the DGAN compressor system. Utilization of these heat exchangers may cool the temperature of the nitrogen, which may allow for less energy to be expended by the DGAN in compression of the nitrogen.
