Fuel savings calculator
Wondering how much you could save in fuel costs by converting your truck fleet to natural gas? With our calculator, you can compare your estimated diesel cost with compressed natural gas (CNG) and liquefied natural gas (LNG) and find out what your payback period will be.

1These costs are estimates and are for illustration purposes only. These are average costs for FortisBC customers who purchased natural gas vehicles between November 2014 and November 2015. Actual prices may vary by specifications and applications.
2Fuel savings depend on factors such as load equipment type, driver performance and distance travelled, so actual savings may vary.
3Based on the incremental natural gas vehicle cost and funds available in the current round of funding.
4Based on the number of vehicles being converted, litres of natural gas fuel consumed annually, incremental natural gas vehicle costs and the estimated FortisBC incentive. This payback period is an estimate and may vary.
5Assumes a 15 per cent efficiency adjustment for a natural gas engine compared to a diesel engine.
6A conversion factor of 25.87 is used to convert from the price per GJ of natural gas fuel to diesel litre equivalent (DLE) pricing. Conversion based on the GHGenius model which is based on Canadian fuel and supply sources. Annual costs do not include vehicle maintenance costs.
7This represents FortisBC’s target price. Actual costs may vary. A conversion factor of 25.87 is used to convert from the price per GJ of natural gas fuel to diesel litre equivalent (DLE) pricing. Conversion based on the GHGenius model which is based on Canadian fuel and supply sources. Rate based on a combination of fuelling station costs and the amount of fuel consumed, and includes commodity, delivery and fixed charges and carbon tax.
