How to calculate Generator cost per kWh?
Generator Cost Per kWh = (Cost Of Fuel × 3412 BTU/kWh) / (Fuel Energy Content × Generator Efficiency) Let's now calculate the cost per kWh for propane generator, diesel generator, gasoline generator, and natural gas one-by-one: Let's look at a quick example of a propane generator.
How much does electricity cost per kWh?
The US national average cost of electricity from the grid is about $0.15/kWh. How does the cost per kWh from generators compare? Obviously, the generator cost per kWh will be higher, otherwise everybody would be using generators for electricity. But how much higher? $0.20/kWh? $0.40/kWh? Even $1.00/kWh?
How much does a propane generator cost per kWh?
Propane Generator Cost Per kWh = ($2.70/Gallon / 3412 BTU/kWh) / (91,452 BTU/Gallon × 0.223) = $0.45 Per kWh Essentially, at current propane prices, the cost to run a propane generator per kWh is $0.45/kWh. Compared to the grid electricity price of about $0.15/kWh, it will cost about 3 times more to generate electricity with a propane generator.
How much does a diesel generator cost per kWh?
Diesel Generator Cost Per kWh = ($3.70/Gallon / 3412 BTU/kWh) / (137,381 BTU/Gallon × 0.27) = $0.34 Per kWh As you can see, the cost to run a diesel generator per kWh is $0.34 per kWh. That is lower than the cost per kWh for propane. In fact, in some states, the electricity cost from the grid and from a diesel generator can be quite comparable.

These benchmarks help measure progress toward goals for reducing solar electricity costs. . Battery capacity (kWh): Larger batteries store more energy and cost more overall, but often have a lower cost per kilowatt-hour. Battery chemistry: Lithium Iron Phosphate (LFP) and Nickel Manganese Cobalt (NMC) are the most common chemistries, each with different price and performance points. With solar energy storage, your panels can continue powering your home even when the sun isn't shining — at night, during cloudy days, or during power. . Solar panels typically range from $50 to $80 per kilowatt-hour (kWh).
