It depends, there are also many power plants that use diesel engines.
Knowing about ship propulsion, compared to turbines, diesels have higher efficiency and longer times between overhaul. Turbines are lighter.
Both mean that if you use turbines, you pay more for fuel and your ship must be docked more often which are a big nono in commercial shipping.
Generally only the military uses turbines in ships.
Sometimes they are installed in for example cruise ships if they need a lot of power and there's no space, / there are balance issues with diesels.
Probably on the land side if you only run it rarely, or your natural gas is extremely cheap, then a less efficient turbine is fine. Generally power plant frame turbines are more old fashioned and less efficient than aircraft turbines.
