# Reading the Bill

> Taking an industrial statement apart line by line, from billing determinants to riders.

An industrial electricity bill is not one price. It is a stack of separate charges — energy, demand, transmission, distribution, riders, taxes — each metered differently and each responding to a different behavior on your site. Most of them are never explained on the bill itself, because the bill assumes you already have the rate schedule in front of you. This section takes the document apart line by line: what a billing determinant is, which numbers come from the meter and which come from a formula, where the multipliers hide, and how to reconcile a statement against the published tariff. If you cannot say which line item a given hour of operation lands in, nothing else on this site will help you. Start here.

- [How to Read an Industrial Electricity Bill, Line by Line](https://thedemandcharge.com/articles/how-to-read-an-industrial-electricity-bill): An industrial statement is four different charges stacked together, each priced on a different determinant. Here is what every line means and which ones respond to timing rather than volume.
- [A 12-Point Audit for Any Commercial Electricity Bill](https://thedemandcharge.com/articles/bill-audit-checklist): A repeatable review that takes about an hour with one bill and one tariff sheet, and finds the errors and mismatches that persist for years because nobody checks.
- [Billing Determinants — The Four Numbers That Set Your Bill](https://thedemandcharge.com/articles/billing-determinants-explained): Every dollar on a commercial electricity statement is a measured quantity multiplied by a price. Learn the four determinants and the bill stops being a mystery.
- [Estimated Reads, True-Ups and Rebills — When the Meter Was Not Read](https://thedemandcharge.com/articles/estimated-reads-and-rebills): An estimated bill is a placeholder that gets corrected later. On a demand tariff the correction is not always straightforward, and it is worth knowing how yours is calculated.
- [How to Get Your Interval Data, and What to Do With It](https://thedemandcharge.com/articles/interval-data-how-to-get-it): A monthly bill tells you a peak happened. Fifteen-minute interval data tells you when, how often and what caused it — and it is usually available for free.
- [Meter Multipliers and CT Ratios — The Line That Silently Scales Your Bill](https://thedemandcharge.com/articles/meter-multiplier-ct-ratio): On instrument-metered services the register reading is multiplied before it reaches the bill. When that multiplier is wrong, every determinant is wrong by the same factor.
- [Riders and Surcharges — The Charges That Are Not in the Rate](https://thedemandcharge.com/articles/riders-surcharges-explained): Fuel adjustments, transmission recovery, efficiency program funding and public benefit charges sit on top of the base rate. What they attach to decides what your savings project is worth.
- [Supply Charges and Delivery Charges on a Business Bill](https://thedemandcharge.com/articles/supply-vs-delivery-charges): In a retail choice state the bill has two halves with two different owners. Shopping moves one of them. The demand charge usually sits in the half that no supplier can touch.
- [kW vs kWh — Why Your Bill Has Two Different Units](https://thedemandcharge.com/articles/kw-vs-kwh-difference): Kilowatts are a rate, kilowatt-hours are a quantity, and your utility bills for both separately. Getting the distinction wrong is how savings projections end up wrong.
