SOLUTION: The electric power generating system 1 opens an electromagnetic valve 62 for sub-fuel and closes a second electromagnetic valve 63B by an operation management controller 82, and opens a first electromagnetic valve 63A, when the system starts the supply of sub-fuel gas F2 to the gas engine 2. Thus, the outlet pressure of a pressure regulator 61 is gradually brought close to the pressure of the air A for combustion in the inlet part (a) of a first mixer 7A. When the supply of sub-fuel gas F2 to the gas engine 2 is stopped, the electric power generating system 1 closes the first electromagnetic valve 63A, and opens the second electromagnetic valve 63B by the operation management controller 82. Thus, the outlet pressure of the pressure regulator 61 is gradually brought close to the pressure of the first fuel/air mixture M1 in the outlet (b) of the first mixer 7A.
