Off-Grid Generator Fuel-Cost & Runtime Calculator
Off-grid Bitcoin mining lives or dies on one number: the effective cost of a kilowatt-hour from your generator. This calculator turns your miner’s wattage, duty cycle, generator fuel type and local fuel price into that $/kWh — plus fuel burned per day, daily and monthly fuel cost, runtime on a tank, and fuel cost per TH/s.
A generator is not free electricity — it is a fuel bill with a machine attached. Whether off-grid mining pays comes down almost entirely to which fuel you burn, not which generator you buy:
- Diesel is dispatchable and energy-dense but expensive — typically around $0.40/kWh at retail diesel prices. It rarely competes with grid power; its place is where no grid exists at all.
- Natural gas is the heat engine of the industry — and when it is flared or stranded wellhead gas that would otherwise be vented or burned off, its cost approaches zero. That is why oil-and-gas Bitcoin mining exists.
- Propane stores indefinitely and burns clean, but small units are only about 15% efficient, so it is a backup / portable / seasonal fuel, not a primary one.
Enter your numbers below. The consumption constants come from D-Central’s off-grid power components dataset; real fuel burn shifts with generator size, load and condition, so treat the output as a planning estimate, not a quote.
Quick answer
The Off-Grid Generator Fuel Calculator turns a miner's wattage, duty cycle, generator fuel type and your local fuel price into the number that actually decides off-grid mining economics: the effective cost of a kilowatt-hour from that genset. It also shows fuel burned per day, daily and monthly fuel cost, runtime on a tank, and fuel cost per TH/s. Diesel typically lands near $0.40/kWh; natural gas is a few cents; flared or stranded wellhead gas can be nearly free.
Fuel type, not the generator, decides whether off-grid mining pays. Flared gas converts otherwise-wasted methane into hashrate at a cost grid power cannot touch; diesel rarely competes unless power is otherwise unavailable.

How it works: effective $/kWh = fuel consumed per kWh × your fuel price. Consumption constants (diesel ~0.25 L/kWh, natural gas ~7.4 ft³/kWh, propane ~4.2 kWh/US gal) are from D-Central's off-grid power components dataset; real burn shifts with genset size, load and condition (avoid chronic light loading / wet-stacking). Compare the result against grid power — e.g. Hydro-Québec rates or the electricity-cost comparison. An estimate, not a quote.
