1These are approximate annual costs for space heating of a typical household in specific FortisBC service areas as identified. A typical household is defined as a single family house approx. 2,300 square feet with average insulation. Anticipated savings will be the difference between annual Renewable Natural Gas (RNG), natural gas, heating oil or propane costs for various heating equipment.

Calculations compare the most energy-efficient heating equipment currently available for natural gas furnace heating, oil furnace heating and propane furnace heating. The calculations are based on FortisBC natural gas rates as of July 2023, and heating oil and propane rates as of December 2022 (source: Home Heating Oil & Propane Study, The Sentis Group, December 2022). Calculations include applicable carbon tax as of April 2023. The cost of RNG depends on the blend you choose. The FortisBC biomethane (or RNG) rate is as of April 2023. You can designate 5, 10, 25, 50 or 100 per cent of the natural gas you use as RNG. You'll also receive a credit on the BC carbon tax on your bill, depending on the blend you choose.

Savings may vary by household and do not include potential rebates and/or incentives.

Renewable Natural Gas is produced in a different manner than conventional natural gas. It is derived from biogas, which is produced from decomposing organic waste from landfills, agricultural waste and wastewater from treatment facilities. The biogas is captured and cleaned to create Renewable Natural Gas (also called biomethane).
