generator run time
(OP)
I have been asked to provide the estimated run time for our 2 megowatt generator with 2000 gallons of fuel. Any one with suggestions on what information I should collect and a formula to plug them into. Many thanks in advance.

There is about 3.38 litres per (U.S.) gallon, i think.
RE: generator run time
At 25% of full load, gpm: 0.725 gpm (164.7 lph)
At 50% of full load, gpm: 1.25 gpm (283.6 lph)
At 75% of full load, gpm: 1.81 gpm (411.8 lph)
At 100% of full load, gpm: 2.50 gpm (558.5 lph)

What warmup or "idle" times do you expect when the generator will be unloaded but running before getting to "full load" - and remember that your actual "full load" will be LOWER than the generator nameplate rated load?
When your generator is called on as an emergency source, will you be able to (automatically or manually) trim low priority loads - what we used to call "rig for reduced electrical" on the submarines - so the actual emergency loads are reduced from your regular operation load?

Thanks y1a1n1k1s1 for coming back and telling us so we can hone our numbers a bit.

You may want to double check that data sheet. The numbers you mention are more likely to be for a 1500kW genset rather than a 2MW. I presume we are all talking about diesel fuel!
RE: generator run time
Fuel temp has two impacts, it is measured at the inlet of the fuel transfer pump, and above 75 to 90 degrees F will affect the fuel consumption rate by volume, at about 125 degrees F on many standby engines it will affect the power output. At between 135 and 150 degrees F it may affect service life of fuel system components due to low lubricity, low sulphur fuels compound this problem.
