Natural gas savings calculator
Cost out off-hours natural gas burn at your own rate, with an optional carbon price, and see what baseload creep is worth over a year.
This section will contain
- Inputs (§G.1): m³/h · off-hours hours · $/m³ · optional carbon price.
- UX: simple first (2–3 inputs → estimate), then an optional Refine step.
- The result is a data-viz moment, not form output: a §E widget with the money figure large and tabular.
- Export as CSV. The on-page result stays free and crawlable — and it is the ONLY thing this deployment delivers: §G.1's emailed PDF report is not built, so nothing on this site offers one. [TOM-REVIEW] §K.2.

What off-hours gas costs
Coming soon
Off-hours burn, with the carbon component priced beside it, because both move together and only one of them shows up on the bill as a line item.
The arithmetic is finished and tested. This calculator stays dark until the published rate constants it depends on are confirmed, because a calculator running on a guessed tariff is worse than no calculator.
The constants this is waiting on
gas.rate[TOM-VALUE]Enbridge Gas current rate schedule. §K.1 #4.gas.ghgFactor[TOM-VALUE]ECCC National Inventory Report emission factor for natural gas. §K.1 #5.gas.carbonPrice[TOM-VALUE]Current federal/provincial carbon pricing schedule — changes annually. §K.1 #6.
Blocking constants: gas.rate · gas.ghgFactor · gas.carbonPrice. §G.2 — “a calculator must not ship with any [TOM-VALUE] constant in its live maths.”
This section will contain
- Blocked on
gas.rate($/m³) — [TOM-VALUE]. Enbridge Gas current rate schedule. §K.1 #4. - Blocked on
gas.ghgFactor(kg CO₂e/m³) — [TOM-VALUE]. ECCC National Inventory Report emission factor for natural gas. §K.1 #5. - Blocked on
gas.carbonPrice($/tonne CO₂e) — [TOM-VALUE]. Current federal/provincial carbon pricing schedule — changes annually. §K.1 #6.
§G.2 hard rule — this calculator cannot ship until the blocking constants land. The other calculators stay live in the meantime.
