PROBLEM TO BE SOLVED: To accurately correct injection quantity of reducing agent in regard to partial load of a generator in a cogeneration system provided with a generator including a combustor and an exhaust gas boiler collecting waste heat of exhaust gas discharged from the combustor. SOLUTION: This cogeneration system is provided with a generator 1 including a combustor 5, an exhaust gas boiler 2 collecting waste heat of exhaust gas discharged from the combustor 5, a catalytic reactor 3 provided in a downstream of the combustor 5, a reducing agent injector 4 injecting reducing agent into exhaust gas in an upstream of the catalytic reactor 3, a NOx concentration detection means 14 detecting NOx concentration in exhaust gas in the upstream of the catalytic reactor 3, and a controller 13 controlling reducing agent injection quantity determined according to power generation amount by the generator 1 based on NOx concentration detected by the NOx concentration detection means 14 at a time of rated load and partial load of the generator 1.
