How to file a utility billing dispute and escalate to the state commission
Most billing disputes are settled by the utility's own billing group if the claim is documented well and filed in writing. A smaller number need the state public utility commission. The details differ by state and by utility, and some customers, such as municipal utilities and electric cooperatives, may fall outside commission jurisdiction altogether. This guide describes the general path. Before you file, read your commission's consumer complaint pages and your utility's tariff terms on billing disputes, because deadlines and forms are set there.

Confirm who regulates the utility
Investor-owned utilities are generally regulated by the state commission. Municipal utilities and cooperatives are often regulated by a city council or a board. Confirm this first, because it determines where escalation goes.
- 2
Document the error
Gather the bills, the tariff provision that applies, meter data or other evidence, and a calculation of the amount in dispute. Identify the periods affected and the account numbers.
- 3
Check the deadlines
Find any lookback limit on refunds and any deadline to dispute a bill in the tariff or commission rules for your state. Treat the shorter plausible limit as your working deadline.
- 4
Authorize any representative
If someone other than the account holder will file or discuss the account, provide a signed letter of authorization in the form the utility accepts.
- 5
File in writing with the utility
Send the dispute to the utility's business billing dispute group or your account manager. State the account, the periods, the facts, the tariff basis, the amount and the remedy requested. Keep the reference number and date.
- 6
Pay the undisputed amount
Many utilities and commissions expect the undisputed portion of the bill to be paid while a dispute is pending, and may allow disconnection for non-payment of it. Check the rules for how a disputed amount should be handled.

Obtain a written response
Follow up if you do not receive a response within the utility's stated time. Ask for the response in writing, with the calculation and the provision relied on for any denial.

Use the commission's informal complaint process
Where the utility's answer is unsatisfactory, most commissions accept a consumer complaint, usually first through an informal process in which commission staff contact the utility and seek a resolution. File with your complete package and the utility's written response.
- 9
Consider a formal complaint
If informal resolution fails, a formal complaint results in a docketed case, often with filing requirements, hearing procedures and a decision. Many commercial customers obtain counsel at this stage. The commission's rules and forms govern the process.
What makes a dispute strong
Disputes succeed when they are specific and checkable. Cite the tariff schedule and section, show the calculation line by line and attach the evidence. Avoid arguments about fairness and focus on what the filed tariff requires.
Keep the tone factual and keep every exchange in writing. If you speak to someone by phone, send a short email summarizing it afterward. A clean paper trail is the most useful thing in any later complaint.
When to bring in outside help
Routine corrections such as a wrong rate schedule or a billing demand error rarely need more than a well-prepared claim. Contested interpretations of a tariff, large multi-year claims or cases involving the utility's own fault in metering may justify a regulatory attorney.
