A power generation system for an internal combustion engine includes: a turbocharger capable of performing a turbocharger power generation using rotation of a turbine provided in an exhaust passage of the internal combustion engine; and a control unit including at least one electronic control unit. The control unit is configured to calculate a first power generation instruction value required for the turbocharger, and determine whether or not a magnitude relationship in which generated power of the turbocharger power generation is larger than an increase amount of a pumping loss of the internal combustion engine resulting from the turbocharger power generation is satisfied based on an operational state of the internal combustion engine, and calculate the first power generation instruction value larger when the magnitude relationship is satisfied than when the magnitude relationship is not satisfied.
