Before You Renegotiate Gas Supply, Reconcile the Whole Bill

Start with a reconciliation, not a price comparison

When a plant’s gas expense rises, the first question is often, “Can we get a better supply price?”

Start somewhere else: “Can we explain what we are paying for?”

Put the utility bill and any separate supplier invoice beside each other. Choose one completed service period. Trace the charges from the meter reading through the billed quantity to the amount due.

Keep three questions separate: Did the plant use more gas? Was the bill calculated correctly? Does the supply agreement still fit the business?

Those questions lead to different actions. Renegotiating supply will not resolve an incorrect meter multiplier. Disputing a bill will not fix a contract that assigns the plant risks management never intended to accept.

Build a one-period gas cost file

Start with two recent utility bills, every page, plus any supplier invoices covering those service periods. Add the executed supply agreement and amendments if you buy gas separately.

Choose a period with complete records, rather than starting with the most confusing month. Establish the normal billing sequence before investigating exceptions.

Create a worksheet with these fields:

Do not force mismatched periods into a comparison. Ask for the billing detail needed to align them. Keep prior balances outside the current-period cost calculation.

The test is straightforward: could someone who did not process these invoices reconstruct the cost?

Make the meter explain the quantity

Before checking a rate, check what it was multiplied by.

Match the meter identifier on the bill to the facility’s records. Then look for the opening and closing readings, reading dates, multiplier and conversion information. If the invoice does not show enough detail, request the underlying calculation.

Watch the units. A meter record expressed as volume and an invoice expressed as energy need a documented conversion before they can be reconciled. Do not treat similar-looking quantities as interchangeable.

Bring the operating calendar into this check. Ask the facility team:

High usage during a shutdown is a question, not a finding. Record the operating explanation, then decide whether the quantity still needs investigation.

If a reading is marked estimated, request the estimate basis and any later reconciliation. Avoid interpreting the next bill’s movement without that history.

Give every charge a job

Next, label each charge according to what it pays for. Use the invoice’s exact wording, but add a plain-English explanation alongside it.

Useful categories include gas supply, utility delivery, transportation, balancing, taxes and adjustments. Leave an item marked “unexplained” if the supporting documents do not establish its purpose.

Where both utility and supplier invoices exist, check the boundary between them. Similar descriptions do not prove duplication. Different descriptions do not prove that two charges are unrelated.

For each uncertain item, ask:

Avoid a broad complaint that “delivery looks too high.” Send a question tied to a line item, service period and calculation.

An effective utility bill audit should turn unfamiliar charges into either documented costs or specific issues requiring correction.

Treat balancing charges as a calculation to reconstruct

If a transportation account includes a balancing or imbalance charge, ask for the supporting statement before accepting or disputing it.

Request the quantities used, the relevant period, the calculation and the contractual assignment of responsibility. Ask the supplier to explain how its records reconcile with the utility’s records.

Keep the questions direct:

Do not substitute a general explanation of balancing for evidence that this particular charge is correct.

Test the delivery schedule separately from the supply price

Find the utility rate schedule code on the bill. Obtain the tariff version applicable to the service period, rather than assuming the latest version applies historically.

Compare the schedule’s eligibility requirements with the facility’s actual service arrangement. Review any stated billing minimums, fixed charges or other obligations only against the applicable documents.

An unfamiliar charge is not automatically an error. Likewise, a charge repeated across many bills is not evidence that it was set up correctly.

If another schedule appears relevant, compare the complete bill under both schedules using the same operating data. A lower individual rate is not enough to support a switch.

Keep the correction list separate from the buying decision

Finish with two lists.

Billing issues belong on the first: unsupported quantities, unexplained calculations, possible duplicate charges and adjustments that do not reconcile.

Purchasing questions belong on the second: price structure, pass-through costs, volume obligations, renewal terms and responsibility for balancing.

Use an energy procurement and hedging review for the second list. A correctly billed contract may still deserve reconsideration. That does not make its charges billing errors.

Give each open issue an owner and a requested document. Operations explains equipment use. Accounts payable reconciles invoices and credits. The contract owner checks supplier obligations.

Before submitting a formal dispute, confirm the applicable process and deadlines.

Close an issue when the explanation or correction is documented, not when someone says they will investigate. Keep unresolved amounts out of expected credits.
