In plain language
What this regime says.
A regulated utility may only charge what its filed tariff allows. Ask which tariff sheet authorises the fee — a charge with no tariff authority must be refunded, and the state commission can order it.
Who is covered
Customers of regulated utilities in the United States.
What you get
A billing correction ordered or brokered by the state public utility commission. No statutory figure.
Where claims go wrong
- Arguing fairness instead of asking for the tariff authority.
- Not distinguishing the regulated utility from a competitive retail supplier, which has no tariff and is governed by contract and state UDAP law.

- State public utility commission tariffs and consumer rulesState public utility law (each state)A regulated utility may charge only what is in its tariff as filed with and approved by the state public utility commission. A charge that is not in the filed tariff is not merely unfair — it is unauthorised, and the commission can order it refunded

Where a figure is indexed, converted or published by a regulator rather than fixed in the instrument, the provenance is recorded separately. Anything marked as a modelled estimate is exactly that — a model, not a statutory number.
