Gas turbines have these advantages over steam plants:
Gas Turbine Power Plant
They are small in size, mass, and initial cost per unit output. Their delivery time is relatively short and they can be installed quickly.
Dr. M. Zahurul Haq
They are quick starting (as low as 10 s), often by remote control.
Professor Department of Mechanical Engineering Bangladesh University of Engineering & Technology (BUET) Dhaka-1000, Bangladesh
They are smooth running and have a capacity factor (percent of time the unit is operating at full power) of 96 to 98 percent. They can use a wide variety of liquid and gaseous fuels including gasified coal and synthetic fuels.

They are subject to fewer environmental restrictions than other prime movers.
