A power fluctuation suppressing method wherein by-product gas produced in a plant is used as a fuel for a high-efficiency combined cycle power generatio n facility so as to generate power, the calorific value is increased while using, as predetermined target values, the total amount of heat per unit tim e and the calorific value per unit amount of gas of the generation fuel prepar ed by adding a material having a calorific value higher than that of the by- product gas to the by-product gas, the calorific value and composition of th e generation fuel prepared by adding a material having a calorific value lower than that of the by-product gas are controlled, thereby adjusting the total amount of heat and the calorific value within predetermined ranges; another power fluctuation suppressing method wherein by-product gas produced in a plant is used as a fuel for a high-efficiency combined cycle power generatio n facility so to generate power and the generated fluctuating power is controlled by alternately using at least two power storages while switching between charging and discharging; and power generation facilities using the methods are disclosed. The short-term fluctuation of the power caused by the operation of the plant can be suppressed, and the long-term fluctuation can be also suppressed.The fluctuation-suppressed surplus power can be supplied to the outside of the plant as stable power by matching the power supply patter n with the power demand pattern.
