Commercial utility bill auditing in Montana

Our Montana supplier-choice coverage focuses on natural gas. Montana’s general electricity supply market is no longer open to choice, so the gas program should not be used to describe statewide electric deregulation.

Montana natural gas utilities and billing review

Representative delivery utilitiesNorthWestern Energy

NorthWestern Energy is the gas delivery example in our Montana guide. An eligible account can have a competitive gas supplier while continuing to pay the local utility for delivery. The statements and supply agreement help identify which company charged each item.

Gas supply choice exists even though the general electricity market is no longer open to choice.

Put the account’s terms in context

When the supplier and delivery company bill separately, keep both invoices for the same service period. Differences in dates, units, or subsequent adjustments can make a comparison misleading if only one statement is available. Historical review follows the account records rather than a generic market price.

Evidence before conclusions

Follow the charge back to the record.

A useful Montana utility audit identifies the disputed line item, the billing dates, and the contract or tariff provision that should apply. We compare the calculation with those records and distinguish a possible error from a supported recovery claim.

A recent statement can help identify questions. A full historical review needs the records for the affected periods, with corrected bills and credits kept alongside the originals.

Montana utility audit questions

Does a gas supplier change replace NorthWestern’s delivery system?

No. Gas supply choice does not change the local transmission and distribution company. We examine the supplier and delivery records as separate parts of the account.

Can you review past utility overpayments?

Our agreed historical review can cover up to 36 months of available records. A recoverable period depends on the account, applicable rules, contract, deadlines, and evidence. One questionable charge is not automatically a three-year refund.

What happens after I upload a bill?

The upload provides an AI-assisted preliminary screening for our team. People review the findings and follow up about records and scope. Recovery work requires a signed agreement and letter of authorization.
