Abstract: Gas turbine power plants augmented with an air injection system for hot air injection to augment power and are used to drive sensitive cogeneration processes are fitted with compressed air storage capability to more smoothly ramp on air injection in the event of sudden and unexpected interruption of the air injection system. Utilizing stored hot air injection prior to starting an air injection system significantly reduces the start-up time of the air injection system.
