Why your commercial energy bill keeps rising (the real reasons)

If you’re wondering why your commercial energy bill keeps rising even though your business hasn’t grown, you’re not imagining it. A utility bill is a stack of separate charges, and several of them can creep up quietly without anyone telling you. Here’s how to read what’s actually happening, the way we do during a Bloat Audit.

Supply vs. delivery: the two halves of the bill

Almost every commercial electricity bill splits into two parts, and they’re set by different people:

• Supply — the cost of the actual electricity (the kilowatt-hours). In deregulated states, you can shop this with a third-party supplier. This is where most rate changes happen.
• Delivery — the cost of moving that power over the wires. This is set by your local utility and approved by regulators, so it’s largely fixed for you.

When your bill climbs, the first move is to figure out which half moved. A higher supply rate is something you may be able to act on. A higher delivery charge usually isn’t, but it tells you not to waste energy chasing the wrong number.

The expired fixed-rate contract that rolled to variable

This is the most common reason a commercial energy bill keeps rising, and it catches good operators all the time. You signed a fixed-rate supply contract a year or two ago, the term quietly ended, and instead of renewing at a new fixed rate you were rolled onto a month-to-month variable rate — often called a “hold-over” or “default” rate.

Variable rates float with the market, and they’re frequently set higher than what you’d get on a fresh fixed contract. The bill doesn’t announce this. It just goes up. Check your supply section for the words “variable,” “month-to-month,” or a contract end date that has already passed.

Broker markups baked into your rate

A lot of business owners sign supply contracts through an energy broker or a salesperson who knocked on the door. Brokers can be useful, but their commission is often built directly into the per-kilowatt-hour rate you pay. You may never see it as a line item.

That’s not automatically a rip-off, but it does mean two things:

• The rate you were “given” may have room in it.
• Comparing one broker quote to your current rate isn’t the same as comparing the underlying market.

If your rate came from a broker, it’s worth knowing what the markup is so you can judge the deal on its merits.

Demand charges: paying for your peak, not your total

Many commercial accounts get billed not just for how much energy they use, but for their highest demand spike in the billing period — usually measured in kilowatts (kW) over a 15-minute window.

That means a single afternoon where you ran every machine, every AC unit, and every light at once can set a demand charge that follows you across the whole month. If your usage looks flat but your bill jumped, look for a “demand,” “kW,” or “capacity” charge. Smoothing out when equipment runs can sometimes move this number without cutting production.

Seasonal rates and time-of-use pricing

Utilities often charge more for power during the months and hours when the grid is strained:

• Seasonal rates — summer rates are commonly higher than winter rates (or vice versa, depending on region).
• Time-of-use — power costs more during peak afternoon hours and less overnight.
• Rate-class changes — if your usage grows past a threshold, the utility can move you to a different, sometimes pricier, rate schedule.

None of these mean a mistake was made. They mean the bill responds to when and how much you use, not just the total.

How to find out which one is hitting you

You don’t have to be an energy expert to narrow it down. Pull a recent bill and check, in order:

• Did the supply rate per kWh change, and is there an expired contract date?
• Does it say variable or month-to-month?
• Is there a separate demand (kW) charge that spiked?
• Did the bill cross into a higher-cost season or rate class?
• Did the rate come from a broker, and do you know the markup?

If you’d rather not decode it yourself, that’s the whole point of a free Bloat Audit. Send us one recent energy bill and a human reviews it for you, then hands back exactly what looks negotiable and what doesn’t. We never contact your utility or supplier and never change anything without your approval, and we won’t promise savings we can’t show you on paper.
