PROBLEM TO BE SOLVED: To provide a cogeneration system, which levels a commercial power, and can be made smaller at a lower cost. SOLUTION: In a cogeneration-system operation time zone in daytime, the smaller and lower cost cogeneration system can be achieved by constituting the cogeneration system, by supplying a first consumption energy with electric power stored in an electric storage device, supplying a second consumption energy with the commercial power, and supplying a third consumption energy with generating power of a power generating device: provided that the first consumption energy is the consumption energy surrounded with a line X1 and a consumption power X(t), the second consumption energy the consumption energy surrounded with the line X1, a line X2 and the consumption power X(t), and the third consumption energy the consumption energy surrounded with the line X2 and the consumption power X(t): where X(t) is a consumption power on a time-consumption power diagram at a power supply point the cogeneration system is located, and the consumption power X(t) is divided into three by the line X1 and the line X2 (X1>X2); and, which is expected to contribute to spreading of the cogeneration system. |
