below some about 25% (or maybe 50% depending on the model) of their full rated capacity, or else condensation can occur in the exhaust system.
That causes corrosion and a shortening of lifetime or at least increased maintenance cost.
The minimum load ratio has no direct effect on the operating hours of the generator, it is simply a constraint on how low the generator power output can go. But raising the minimum load ratio could indirectly lead to fewer operating hours because the generator is more productive when it runs.
A generator, rated at 16 MW, should be able to continuously supply a load of 16 MW. You don't need to compute its 'minimum load', because the minimum load will be zero watts! In other words, you can run the generator with no load whatsoever if you wish to waste fuel.The point is that the power supplied by a generator is determined by the load, NOT by the generator itself -so it is important that the generator is capable of supplying the maximum load applied to it. A generator's 'rated power output' simply tells us the maximum load it is capable of supplying.
The causes of over loading in generator comes from the action of applying more load that the generator is rated for. An example using a 5000 watt generator and a connected load of 6000 watts.
If the generator is to maintain the same rpm and power output, then a heavier load will increase the diesel consumption. The revolutions per minute the generator runs will increase as the load increases, thereby resulting in an increase in diesel consumption to maintain the high rpm. A Generator has a governor which attempts to maintain frequency at 60 Hz for North America. For the generator to increase the power output at the same frequency, the governor will increase the fuel and air to the engine. The fuel consumption will not be linear because of the curves associated with the particular engine. The fuel to KWH is know as the heat rate curve for the generator.
Have a look at AuroraGenerators.com If it is diesel your looking at about 1 gallon per hour however likely you are not running at full load. You can expect to be using on average 0.5 gallons per hour on an Aurora Diesel Generator
The load on a generator is a general word for whatever device is connected to it to use the power that is being generated.

Any device that uses the generator to supply its operating voltage is electrically classed as a generator load.

On an average load on a 15 kc DG is about 4 littered of diesel per hour.
The fuel usage will be based on the load applied to the generator and how many KW the generator outputs. The more load the higher the fuel consumption. You do not list the output of the generator nor the load so all I do is point you to the diesel fuel generator consumption chart. Click the link to see the chart where you can figure it yourself.
The size of the generator is based on the size of the load you want to supply. Size up the load in watts or amps along with what phase (single or three) and voltage that the load requires. These are needed to give a complete answer.
