Understanding Generators and Their Fuel Requirements
Generators play a crucial role in providing power where it’s not available from the grid. At the heart of their operation is the conversion of fuel into electricity. Here’s a brief look at how they work and their fuel requirements:
How Generators Work:
- Generators convert mechanical energy into electrical power. An internal combustion engine, powered by a fuel source such as propane, diesel, or gasoline, drives this process.
- The engine turns a turbine, which then generates electrical energy through electromagnetic induction.
- The efficiency and output of a unit depend significantly on the type of fuel used and the engine’s design.
Types of Generators and Fuel Needs:
- Portable: Often run on gasoline or propane. They are smaller, used for temporary power solutions like camping or emergency backup during power outages.
- Standby: Typically larger and used for prolonged power outages. These often run on propane or natural gas due to their longer shelf life and availability.
- Industrial: Designed for heavy-duty applications, they usually run on diesel, known for its high energy density and efficiency in large-scale operations.
Fuel Efficiency:
- Fuel efficiency is a crucial aspect of its performance. It determines how long a generator can run on a given amount of fuel.
- Propane is particularly efficient and clean-burning, which makes it a popular choice. It produces fewer emissions and can be stored for long periods without degradation.
- The choice of fuel impacts not only operational costs but also maintenance needs and environmental footprint.
Understanding these basics helps you appreciate why choosing the right fuel, and consequently, the right size of the propane tank, is fundamental for your generator’s optimal performance. It’s not just about keeping the lights on; it’s about doing it efficiently, reliably, and responsibly.
Propane as a Fuel Source: Advantages and Comparisons
When you’re considering fuel options for your generator, propane stands out as an excellent choice for several reasons. Here’s why you might prefer propane over other fuels like diesel or natural gas:

What Size Propane Tank Do You Need for 22kw Generator
The tank size you need for a 22kw generator will primarily depend on how long you intend to run the unit. Considerably, a 120-gallon propane tank is sufficient to run the equipment for about 36-48 hours on average. For larger tank, let’s say a 500-gallon tank, the system can run for about 9 days without stopping.
To make a computation on how much propane it consumes, a 22kw capacity consumes about 2.5-2.8 gallons per hour; If the propane is at $2.75 per gallon, that is approximately $165-$184 per day of operation. This is just a conservative computation, consumption will also depend on the load of the unit.
What Size Propane Tank Do You Need for a 20kw Generator?
Again, a 20kw capacity there isn’t much difference from a 22kw. The most common tank size for a 20kw capacity is the 120-gallon, this is enough to power the unit for approximately 52 hours on average. While the 500-gallon tank will run the machine for about 220 hours.
But just being 20kw, it consumes a little less fuel. You can expect to spend about $150-$160 per day to run the the unit. Then again, a full-load unit in continuous operation will consume a lot of fuel. Everything will depend on the load the unit handles at a given time.
Those figures mentioned above are just a rough estimate. Propane prices vary from state to state so it is not possible to determine an exact amount. The aspect is the appliances that consume electricity, the more appliances that are turned on at a given time, the more fuel the unit consumes.
A 20lb Propane Tank Can Give a Short Run
A 20-pound tank you might have stored in your home will run the equipment for about six hours. A 20-lb propane tank can hold 4.6 gallons of propane, which is not enough to run the unit for a long period obviously. So, depending on the propane load in the tank, the operating period may vary.
The other factors are the wattage of the equipment. Nowadays, there are 4000-watt, 5000-watt, 7500-watt, and 10000-watt available in the market that run on propane and model and brand of the equipment.
