Trying to use Nat Gas to fire the old coal boiler would be about half as efficient as putting in a combined cycle power turbine. A Power Turbine also generates electricity from the expansion of gases, not just heat.

I understand, but that’s not what I asked.
It seems they could leave the dynamos and building in place, and install some new gear, engines and cabling.
How can gas turbines offer more efficiency than NG piston engines? It seems they produce a lot of power in a small package, but use tons and tons of fuel.
