Published benchmarks like "the average small-business electric bill is $X" are nearly useless for diagnosing your own bill. A bill is the product of three things that move independently: how much electricity you use, the rate you pay per kWh, and the fixed and demand charges your utility tariff adds. Change any one of those and the total can double.
What you actually need is a baseline built from your own meter data — and the U.S. Energy Information Administration (EIA) gives you the only benchmark worth comparing against: the U.S. average commercial electricity price runs roughly 12–13¢/kWh. Everything else is arithmetic you can do in 10 minutes from one bill.
Commercial electric bills have four components. Understanding each one tells you where to push.
A flat monthly fee for the metered connection — usually $15–$50 on small commercial schedules. It doesn't change with usage. If you run a tiny office using 200 kWh a month, this charge alone can push your effective rate well above the headline energy rate.
Cents per kWh for every unit of electricity you consume. The EIA puts the U.S. commercial average at roughly 12–13¢/kWh, and the same EIA data shows state averages ranging from under 9¢ in parts of the Southeast to more than 20¢ in Massachusetts and Hawaii. Your supply rate — the competitive portion — lives inside this number and is the part you can shop.
Dollars per kilowatt, billed on your highest 15-minute average power draw of the month. Most commercial tariffs apply this above 10–25 kW of peak demand. Demand charges don't track consumption — they track your worst spike. One afternoon with every piece of equipment running simultaneously sets the charge for the entire month.
Line items below the energy charge covering distribution upgrades, renewable portfolio standards, nuclear decommissioning, and state-mandated programs. These are set by utility tariffs and regulators — no supplier can remove them. They're worth understanding because they explain why two businesses on the same supply contract pay different totals.
Illustrative example: A storefront using 2,000 kWh in a month at 13¢/kWh plus a $30 customer charge lands near $290 — before any demand charge. Add a 15 kW peak and a hypothetical $12/kW demand rate and the bill reaches $470. Same building, same kWh, 62% higher bill.
These are the variables that explain why two businesses in the same industry and the same city can have bills that look nothing alike.
| Driver | Why it moves your bill | What you control |
|---|---|---|
| Total consumption (kWh) | More usage equals higher energy and sometimes higher demand charges. HVAC is usually the largest single load. | Equipment upgrades, setpoint schedules, LED lighting, occupancy controls |
| Supply rate (¢/kWh) | The competitive portion of the energy charge. Holdover contracts and default service can run well above the market rate you could lock by shopping. | Competitive supplier contracts in deregulated states (TX, OH, PA, MA, NJ, DC) |
| Peak demand (kW) | One high-coincidence interval sets the demand charge for the whole month — often one of the largest lines on commercial schedules. | Staggered equipment startup, load scheduling, interval-data monitoring |
| Rate class | Utilities set different tariffs for different customer sizes. A business that has grown past a threshold may qualify for a lower-cost commercial schedule but hasn't been moved. | Request a rate-class review from your utility; compare available schedules in the tariff |
Pull last month's bill and work through three numbers.
It appears on every bill, usually near the top or in the usage summary. Write it down.
Divide total charges (everything on the bill) by total kWh. This is your all-in effective rate — the honest number that includes customer charges, demand charges, and riders, not just the headline energy rate. A storefront paying $470 on 2,000 kWh has an effective rate of 23.5¢/kWh even if the supply rate is 13¢.
Your state utility commission publishes the default supply (standard offer or provider-of-last-resort) rate. In deregulated states — Texas, Ohio, Pennsylvania, Massachusetts, New Jersey, Washington DC — this is the rate you pay if you've never switched suppliers, and it's often above market. If your effective rate sits far above the default supply rate, the gap is mostly demand charges, riders, and fixed charges — not supply. If your supply rate alone (find it as a line item) exceeds the default, you're on a stale contract.
Three situations signal a bill problem worth acting on:
Effective rate far above default supply. If your supply line-item sits materially above what your utility commission posts as the default rate, you're likely on a holdover contract — an auto-renewed clause that kept you on old pricing after a fixed-term deal expired. Suppliers are required to disclose holdover terms, but few businesses notice when the contract rolls.
Wrong rate class for your load profile. Businesses that have grown — added a second HVAC unit, expanded floor space, taken on production equipment — often hit a higher demand threshold without being moved to the commercial tariff tier that fits. Utilities rarely audit your account proactively. Request a rate-class review; the downside is zero.
Demand charges dominating the bill. As a rule of thumb, once demand grows into a leading share of your bill, load management matters more than supply shopping. Switching to a cheaper supplier helps, but flattening the peak saves more per dollar of effort.
No single number is accurate because a bill is the product of three variables: how many kWh the business uses, the rate it pays per kWh, and the fixed charges its utility tariff adds on top. The U.S. Energy Information Administration (EIA) puts the average commercial electricity price at roughly 12–13¢/kWh, but a storefront in Massachusetts pays more than a warehouse in Texas, and a restaurant pays more than an office using the same square footage. Your real baseline is on last month's bill: divide total charges by total kWh to get your effective rate, then compare that against your state's default supply rate.
A commercial bill typically has four components. First, a customer charge — a flat monthly fee for being connected, usually $15–$50 for small commercial accounts. Second, an energy charge — cents per kWh for total consumption. Third, a demand charge — dollars per kW, based on your highest 15-minute power draw, which applies on most commercial schedules above 10–25 kW of peak demand. Fourth, riders and pass-throughs — distribution upgrades, renewable portfolio standards, nuclear decommissioning — listed as line items. Switching suppliers changes the energy charge only; the rest stays fixed by the utility tariff.
Pull one bill and do the 10-minute check: find the total kWh used, divide total charges by that number to get your effective rate, then look up your state's default supply rate. If your effective rate sits well above the default supply rate — especially if you've been on the same contract for more than 24 months — you're almost certainly on a holdover rate. Also check the rate class at the top of the bill; if you've grown past the threshold for your current class, you may qualify for a lower tariff tier.
It depends on the utility tariff and how much power the business draws at its peak moment. Most utilities apply demand billing to commercial accounts above roughly 10–25 kW of coincident peak demand. A small office rarely crosses that line. A restaurant, salon, or light-manufacturing space often does — HVAC, ovens, and equipment starting together can spike well past the threshold. If demand charges appear on your bill, the kW line — not the kWh line — is where to focus first.
Challenge the bill when your effective rate (total charges ÷ kWh) sits far above the default supply rate published by your state utility commission, when you've rolled onto a holdover or evergreen clause after a fixed-term contract expired, or when the rate class on the bill doesn't match your actual usage profile. Misclassified rate classes happen after a business expands — and utilities don't proactively move you to a cheaper schedule when your load profile changes.
