The Wrong Meter Costs More: Commercial Power Carries a 55.5% Premium

Two buildings on the same feeder can pay sharply different prices for the same electricity, and the difference is set by rate class, not by the market. Here is what the commercial premium over industrial power costs a working shop, and how to find out which meter you are on.

Drive any industrial corridor in America and the buildings look interchangeable: tilt-up concrete, a loading dock, a transformer humming behind a chain-link fence. The electric bills are not interchangeable. As of May 2026, the average commercial customer in the United States paid 13.5¢/kWh for electricity while the average industrial customer paid 8.7¢/kWh, according to the Energy Information Administration. Same grid, same electrons, and a 55.5% premium decided not by what a building does but by how its meter is classified. For a small manufacturer sitting on a commercial tariff, that premium is a cost nobody chose, few ever audit, and almost no one prices into a quote. It compounds through every machine hour the shop bills out.

Same electrons, two prices

Both figures come from the EIA's monthly accounting of average retail electricity prices, in cents per kilowatt-hour, blended across every state and utility. These are delivered prices: generation plus transmission and distribution, the number that actually lands on a bill rather than a wholesale spot rate. The gap between the classes is structural, not accidental. Industrial customers take service at higher voltages, often through their own substation, so the utility skips much of the low-voltage distribution network that commercial accounts depend on. Industrial loads also run flatter. A plant pulling steady power across two shifts is cheaper to serve per kilowatt-hour than an office block that spikes at nine in the morning and empties out by six.

Utilities price that difference through tariff schedules and regulators approve it; none of it is arbitrary. But the boundary between the classes is administrative, and a surprising amount of real manufacturing sits on the wrong side of it. A machine shop in a flex space zoned commercial. A fabricator subleasing a bay in a building wired for retail. A growing operation that never revisited the account it inherited with the lease. These shops frequently pay the schedule the landlord signed up for years ago, and the utility does not volunteer a reclassification. The premium just arrives, month after month, buried inside a delivered rate the shop never chose and rarely questions.

Commercial premium over industrial power, May 2026: 55.5%. Commercial service averages 13.5¢/kWh against 8.7¢/kWh for industrial accounts, a gap of 4.8 cents on every kilowatt-hour (EIA, delivered price).

What the premium does to a machine hour

Put numbers on it. Take a shop with about 50 kW of average draw across its spindles, compressor, chiller, and lights, running two shifts, roughly 4,000 run-hours a year. That works out to 200,000 kilowatt-hours annually. On the industrial rate, the year's power costs about $17,420. On the commercial rate, the identical consumption costs about $27,080. The classification alone is worth $9,660 a year, roughly $2.42 on every run-hour, before anyone hunts down a compressed-air leak or powers off an idle spindle. That is real money for a shop this size, and unlike a material surcharge it never appears as a line a customer can see or a buyer can push back on. It simply erodes the margin the machine-hour rate was built to protect.

The number scales linearly, which is what makes it dangerous. Double the connected load or add a third shift and the classification gap doubles with it. The shops most exposed are precisely the ones growing into industrial-scale consumption on a commercial-scale contract, paying the premium on every incremental kilowatt-hour just as their volumes would justify a better schedule.

The commercial premium is not a market price. It is a classification, and classifications can be appealed.

The gap is not closing

This is not a pandemic artifact working its way out of the system. Commercial power has climbed 21.4% since year-end 2021, from 11.15 cents per kilowatt-hour to 13.54 across that window, and the series touched 14.4¢ in February 2026, the highest reading in its archive. The latest print sits at the 76th percentile of the 5-year history and is up 4.7% from a year ago. A rate that has spent five years grinding upward is not a blip a shop can wait out; it is the new baseline.

Industrial power has been climbing too. Across its archived window, the industrial rate has ranged from 8.2¢ in April 2025 to 9.3¢ in July 2025, and the gap between the classes has persisted through the entire move. The mechanics favor persistence. Much of the recent increase on the grid is delivery cost, the poles and wires and substations, and delivery lands hardest on the classes served at low voltage. When the wires get more expensive, the commercial meter feels it first and keeps more of it. A shop waiting for the premium to mean-revert on its own is making a bet the rate structure does not support.

What to do with the number

Start with the bill, not the spreadsheet. Every utility invoice carries a rate schedule code, and that code, not the sign on the building, determines which of these two prices a shop pays. Call the utility and ask three questions: which schedule the account is on, what the industrial or large general-service alternatives require in service voltage, demand minimums, and load factor, and what a reclassification would take. Some shops will discover they already qualify and have simply never asked. Others will find the threshold requires a service upgrade or a demand commitment with its own payback arithmetic. Either answer converts an invisible premium into an explicit decision, which is the only kind a manager can act on.

Then reprice. The rate that belongs in a machine-hour calculation is the one on the actual bill: not a national average, not the number from the year the shop last rebuilt its rates. A shop quoting off a stale or misclassified power price is donating the difference on every job. And if an expansion or a relocation is on the table, rate class belongs in the siting analysis alongside wages and freight, because the meter a building comes with is part of its price. The premium documented here is one of the few costs in manufacturing that can sometimes be removed with a phone call and a form. It is worth an afternoon to find out.

Put your connected load, run-hours, and the rate on your actual bill into the energy cost per part calculator, then rebuild your machine-hour rate with the result. Run your shop's numbers
