<P>PROBLEM TO BE SOLVED: To obtain a driving method for emergency gas turbine power generation equipment capable of restarting power supply by promptly restarting an emergency gas turbine power generation facility even while a commercial power source is interrupted again. Ž<P>SOLUTION: Power is supplied to a load by driving a plurality of the gas turbine power generation facilities 19, 29 when commercial power source is interrupted. Power is supplied to the load from the commercial power source when the commercial power source is restored, and stop operation of a plurality of the gas turbine power generation facilities 19, 29 is started at different stop operation start timing respectively. When power interruption occurs again before a plurality of the gas turbine power generation facilities 19, 29 lowers to the rotation speed to restart or less, at least one of a plurality of the gas turbine power generation facilities 19, 29 is restarted earlier than the timing when both of a plurality of the gas turbine power generation facilities 19, 29 synchronously start power interruption operation.
