Key takeaways
- An accepted claim lets an analyst verify the error without doing research: the account, period, tariff basis, calculation and requested remedy are all on one page.
- Written authorization from the account holder is required before a third party can discuss or dispute an account.
- Escalate only after the utility's billing review has issued a written answer; most claims are resolved there.
The analyst's problem is verification
A utility billing analyst receiving a dispute has a queue of them. The question for each is whether the claim can be verified from the information in front of them and from the utility's own records. A claim that says the bill seems too high gets a request for more information. A claim that says the account was billed under schedule X, the tariff requires schedule Y for these reasons, and the difference for these months is this amount, can be checked in minutes.
Every part of a good claim is aimed at removing steps from the analyst's review. That is not a courtesy. It is what moves a claim from the pending pile to the approved one.
The core of a claim package
A complete package includes: the account number and service address; the billing periods affected; copies of the bills; the specific tariff provision, with schedule name and section; a statement of what the bill did and what the tariff requires; a calculation showing the corrected amounts line by line; the total refund requested; and the evidence that supports the factual premise, such as meter data or a site closure notice.
The calculation matters most. It should use the utility's own rate components and the same billing determinants the utility used, changing only the item in dispute. If the analyst can see that everything else matches the bill, the dispute is narrow, and narrow disputes are resolved faster.
Authorization and who may file
Utilities will generally discuss an account only with the account holder or someone the holder has authorized in writing. A third party filing on a customer's behalf needs a signed letter of authorization naming the accounts, and some utilities have their own form or require a notarized version for certain actions. Check the utility's process before submitting.
Trace Global files claims on behalf of customers under a signed letter of authorization. It is not a utility or a law firm, and the credit or refund is issued by the utility to the customer, not to the filer.
Where to send it and what to expect
Most utilities have a business billing dispute or commercial customer service group, and larger accounts may have an assigned account manager. Start there, in writing, and keep the reference number. A written dispute usually triggers a review period, after which the utility responds with an adjustment, a partial adjustment or a denial with a stated reason.
Across the claims Trace Global files, 94% are accepted in full or in part, and the median time from filing to credit or check is 47 days. Those figures include simple corrections and more involved multi-period claims, and individual timelines vary by utility and by how much history must be rebuilt.
When the answer is no
A denial should come with a reason. If the reason is factual, such as a disagreement over the meter reading, answer with more evidence: an interval export, an independent meter test, photographs of the nameplate. If the reason is interpretive, such as a different reading of the tariff, ask for the specific provision relied upon.
If a written denial stands and the customer believes the tariff supports the claim, state utility commissions generally run a consumer complaint process, often informal first and then formal. The details differ by state and the process is worth reading on the commission's own site before filing. Most claims never need it, but a clean record of the utility's written response makes it much stronger when they do.
