Commercial Gas Pricing | Commodity, Fees & Delivery

Build the price from its defined components

A national average is historical context, not an executable business offer. Use the tools for transparent arithmetic and written eligible offers for the actual purchasing decision.

Worked example: compare the full modeled supply scope

Assume hypothetical annual use of 12,000 therms. Offer A is $0.75 per therm plus $20 monthly; offer B is $0.70 plus $100 monthly. A models to $9,240 and B to $9,600, so B’s lower commodity price is $360 more expensive over the year. Delivery, taxes, exit costs and unlisted items are excluded.

That conclusion depends on the exact included charges and the assumed volume. If the usage forecast changes, rerun the comparison. If one rate is indexed or seasonal, a constant annual price is not an adequate substitute for monthly modeling. Keep the quoted units, service months and fee basis next to the normalized result so the reviewer can reproduce it without mistaking invented example prices for available commercial offers.

Build the complete price stack

EIA separates physical volume from energy units and describes supply, demand and storage influences on market prices. For an actual offer, distinguish the benchmark or fixed commodity price, location differential, service adders, recurring supplier fees and retained utility charges. Identify which line is contractual, which follows a tariff and which is only a budget assumption. EIA: natural gas volume, heat content and energy units; EIA: supply, demand, weather and storage price drivers.

Choose the denominator that matches the question

Supply dollars divided by normalized energy can describe a modeled supply cost. Total utility dollars divided by that energy describes a broader average that may include fixed charges, taxes or corrections. Do not use the second figure as if it were a competing supplier’s commodity rate. Keep the time period and included charges adjacent to every unit-cost number in the approval packet. EIA: natural gas customer choice and eligibility.

A comparison definition placed beside the result

For every displayed total, state the energy unit, service period, volume assumption, included charges and excluded charges. Identify which rates are written offers, tariff components or hypothetical inputs. Keep a versioned copy of the source so another reviewer can reproduce the comparison after a website changes. Test a lower-usage case where fixed fees matter more. If an offer contains a monthly index, use a monthly model instead of disguising that uncertainty inside one constant annual rate.

Use the appropriate planning tool

Fee-adjusted offer comparison: Use the flat-rate tool when its assumptions fit; move to the seasonal budget for monthly prices or volumes.
