You used less gas, or gas cost less. You used 79 therms this period against 112 in May.
Charges and taxes for the period; any previous balance is not part of the change.
Milder weather
This period had 2 heating degree days against 38 — 95% milder. At the same gas per degree of cold, that alone is about 32 therms less.
Rates and charges
Since your May bill, the cost-of-service adjustment (GRIP) was added (+$2.43).
Taxes and fees
The city franchise fee and taxes are a percentage of the charges above, so they move with them.
Natural gas cost
The purchased gas adjustment — what we pay for the gas itself, passed through at no markup — fell from $0.3380 to $0.3294 a therm.
Budget billing
About $214.00 a month, from the last twelve bills, settled once a year.
Payment arrangement
Spread this bill over the next few without collection activity.
Energy assistance referral
Local agencies; a pledge pauses collections while it is processed.

Starting from the May 2025 bill, the engine re-prices it at the volume the weather predicts, then at the volume used, then swaps in this period’s gas cost, weather adjustment, and each base rate in turn. Every step is priced line by line and rounded the way the biller writes lines, so the steps add to the real difference — −$14.02 — to the cent. It reproduces every issued bill in the system exactly.
