Frequently Asked Questions
Can my utility really make billing errors?
Yes. Utilities manage millions of data points every month, and errors—like incorrect meter readings, wrong rate class assignments, or misapplied demand charges—do occur. Even small mistakes repeated over months can add up to significant costs.
How far back can I claim refunds?
It depends on your state and utility, but most allow claims for two to three years of past bills. Some jurisdictions permit even longer lookbacks if errors are well documented. The sooner errors are found, the better your chances of securing refunds.
Do I need special software to audit bills?
Not necessarily. Software can help, but the real value lies in expertise—knowing how tariffs work, how to identify irregularities, and how to interpret usage patterns. A skilled auditor can often uncover issues that software alone may miss.
