Power is torque x speed. If your torque for 23kW is 2280Nm at 100 rpm the generator will require 2280 x 100/250 Nm to produce 23kW.

Torque is decided by the speed for a given power. Each stage of conversion is less than perfect so you will loose a little in the gearbox so your input to the generator may be down to 22kW. Efficiency of 93% for a 20kW alternator is good going if you can manage it.

How accurate the 23kW calculation is is another matter I can only take that as given.
