Abstract

A cogeneration system (1) comprising a electric power and heat generator (11), an electric energy and heat quantity prediction means (101) for calculating prediction values of electric energy and heat quantity in a predetermined time zone on a prediction object day based on prestored electric energy and heat quantity used in the predetermined time zone, and a means (102) for controlling electric power and heat generated from the electric power and heat generator based on a prediction value calculated by the electric energy and heat quantity prediction means. The electric energy and heat quantity prediction means (101) calculated the prediction value by setting the weighting coefficients for the electric energy and heat quantity used one day before and seven days before the prediction object day, out of the electric energy and heat quantity used from one day to seven days before the prediction object day, larger than those for the electric energy and heat quantity used other days.
