How much propane will be needed for 20 kw generator use per hour?

It requires 2 horsepower to produce 1000 watts of energy per hour under load

Under load each horsepower consumes 10000 BTU per hour

Propane contains 92,000 BTU per gallon

Propane weights 4.2 pounds per gallon

How much Propane does a 20 kw generator use per hour?

Using these factors how long can a 5000-watt generator run on a 500 gallon propane tank at 50 capacity.

  • 10 horse power at 50% would use 5 HP to generate 2500 watts of electricity
  • 5HP X 10,000 BTU would consume 50,000 BTU per hour
  • 500 gallons X 92,000 = 46,000,000 BTU of energy in a full 500 gallon tank
  • 46,000,000 BTU divided by 50,000 BTU = 920
  • A 500-gallon tank that is full would run a 500-watt generator at ½ capacity for 920 hours.

How long will a generator run continuously?

A natural gas generator will run as long as it is required to run. A natural gas line will always have the pressure it needs to operate. During a power outage the line will continue to have pressure. A generator powered by natural gas will automatically turn itself on and run until the main power source is restored.

Final verdict

A generator powered by propane will run until the propane supply is exhausted. Most propane tanks, either above or below ground, are 500 to 1,000 gallons.

Expect a propane powered generator to burn 2-3 gallons an hour. A 500-gallon tank will power your home continuously for a week. A 1,000-gallon tank will last for 2 weeks.

By knowing the Generac home generator fuel consumption rate, an Assurance Power Systems specialist can assist you in determining the size liquid propane tank that would hold the needed quantity for the estimated amount of running time you anticipate for you needs.

In many areas natural gas lines and propane tanks are already installed, and your APS specialist can also determine the most effective and efficient ways to use any existing gas lines and storage tanks.

Using our previously mentioned Generac Home Generator sizes, a 22 KW Generac generator would consume 5.9 cubic meters per hour of natural gas at ½ load and 9.7 cubic meters per hour at full load.

These are mere approximations as generator fuel consumption rates for different models, and by running at different loads may vary the fuel usage to some degree.

It is also important to understand that in addition to the different loads that will affect fuel consumption caused by the number and size of appliances you are using, the effectiveness of home insulation may also factor into fuel consumption, as it directly affects the load placed on air conditioning.

The technicians at Assurance Power Systems are experts in determining the proper size generator for your needs and what type of fuel should power it and now you know how much propane does a 20 kw generator use per hour.

I hope that this article will help you make better decisions in the future about what to buy considering the special needs of the situation you find yourself in, considering that less power means less consumption.
