PROBLEM TO BE SOLVED: To provide the subject method in a compound power generation using coal as a raw material, which method having the capability of alteration in power load with constantly treating an approximately definite coal amount specified for a coal thermal cracking furnace as well as without reducing in the power generation efficiency. SOLUTION: A method for generating electricity, comprising a power generation process by the using as a fuel of thermal cracking reaction products brought from a coal thermal cracking furnace in which coal is blown into a high temperature gas formed by gasification by oxygen of coal, char and carbonaceous raw material and is subjected to rapid heating and thermal cracking reaction in a gas stream layer, and treating constantly an approximately definite coal amount specified for the coal thermal cracking furnace, which method generates electricity, when a low load of electricity, using a formed gas and stores a formed oil, on the other hand, generates electricity, when a high load of electricity, using a formed gas, oil and the oil having been previously stored. Furthermore, a hydrogen concentration of the thermal cracking atmospheric gas shall be 30% or above by blending hydrogen gas into a high temperature gas formed by gasification by oxygen of coal, char and carbonaceous raw material.
