It would be strange to have a diesel generator that could power a building only for a few hours. I’ve commissioned numerous diesel generators to provide power to power plants if the transmission line is down and generally they can go at least three days. A diesel generator that could use all its fuel in 3 hours would be like a car with a 1 gallon tank.
