Filed tariffs, quoted from the filing
Commercial electricity tariffs by utility
What each utility’s own filed tariff prints for its commercial schedule: the document, the schedule and the day we read it. Quoted, never estimated.
Delivery charges come from the utility’s filed tariff, whichever supplier you choose. This page lists the 16 of 38 utilities on this site whose tariff we have read and quoted, in 8 states, with the schedule, document and read date. Alberta’s 4 distributors are listed too. These are schedule figures, not bill estimates.

U.S. utilities
The delivery half of a commercial bill follows the address. The utility’s tariff sets it, a regulator approves it, and changing supplier does not change it. Select a utility to see the schedule it quotes, the figures and what is left out.
Alberta
Alberta’s distributors file tariffs by rate class, and the delivery charges follow the distributor, not the retailer. The rows are in the Alberta business guide, in Canadian dollars.

How to use a tariff row
- Find the schedule code on the bill first. A utility has many schedules, and the one on the bill decides which row applies.
- Read the units. A fixed charge is per month or per day, an energy charge is per kWh, a demand charge is per kW or per kVA, and a utility may print the same class in different units from another.
- Remember what is not there. Riders, supply, transmission pass-throughs, taxes and local fees are billed on top, and each page says which it leaves out.
- Check the date. Tariffs change by filing. Each row carries the day it was read, and is withdrawn from this site after the last day we vouch for it, until it is read again.
The ideas behind the lines are in supply versus delivery, ratchet clauses and load factor.

Common questions
- Where can I find my utility’s commercial rate schedule?
- In the utility’s filed tariff, which the utility or its regulator publishes. The bill prints the rate schedule code, and the tariff lists what that schedule charges. This page links the tariff documents we have read, and each utility page says which schedule it quotes.
- Does this page tell me what my bill will be?
- No. It quotes schedule figures as the tariff prints them. A bill also carries riders, supply charges, taxes and fees that depend on the account, so the figures here are context for reading a bill, not an estimate of one.
- Why are some utilities missing?
- A tariff is quoted only after it has been read and every quoted figure checked against the document. 22 of the 38 utilities on this site have not been read yet, and their pages say so rather than guessing.
A tariff row tells you what a schedule charges. Your bill tells you which schedule you are on and what you actually pay. Nobody calls unless you ask.
