[RE-wrenches] Generator Operating Cost

[Nick Soleil]

I have seen some 10 and 12 KW Kohler RZ gennys get ~16,000 hours.  Those are 
water cooled units, of course.

I do not have a lot of experiance but for back up commerical generatoers,
 but on smaller generators, 5 to 10 kW top end overhaul 1000 hours max, total 
3000 hours
Medium size 50 to 150 kW top end 2000 hours total overhaul 8 to 10,000 hours.  
Big engines 4 to 5000 hrs for top end and bottom end up to 20,000 hours

Fellow wrenches,

Anyone have some information, perhaps a spreadsheet, showing the cost to operate 

a generator?
How many hours should one expect a water-cooled propane generator to operate 
before overhaul or retirement? 25,000?
How many hours should one expect a water-cooled diesel generator to operate 
before overhaul or retirement? 40,000?


Thanks.
