We Just Want the Lowest Price!

Why the lowest price is harder to find than it looks

The buyer who treats a competitive bid like a used-car haggle usually feels like the sharpest person in the room. Collect a few numbers, play the suppliers off each other, pick the smallest one, and walk away a winner. That confidence is exactly what a headstrong buyer gets played on. The number they picked was smallest for a reason that had nothing to do with getting a better deal.

There are two problems, and they compound each other.

A buyer who does not account for both ends up comparing a stripped Thursday bid against a complete Monday bid and calling it a win. They sign. The real total shows up on the second or third invoice, when the contract is already locked and there is no recourse. The rest of this page walks through both traps, names the tricks by name, and shows the several disguises the same charge wears from one bid to the next.

The same bid on two different days

Here is a common scene. A buyer gathers three quotes over two business weeks and picks the lowest. Supplier C came in cheapest, so C wins. The buyer never learns that C only looked cheapest because the market happened to dip the day C quoted, and that C is actually carrying the fattest margin of the three. Toggle the comparison below to see what happens when all three are priced on the same day, the way a real solicitation is run.

Numbers are illustrative and cover the supply component only, the part you actually shop. Delivery is a separate charge the utility sets and passes through at cost, and taxes go to the state and your city with the supplier only collecting them. Neither is where the games happen. The real trap is a bill that refuses to keep those two apart from your supply charges, which we take apart further down.

This is why a bid in Texas is usually good only on the day it is presented, and why gathering quotes over two weeks is not comparison shopping. It is collecting snapshots of different markets and pretending they line up. The only honest way to compare is to make every supplier quote at the same moment.

What is actually inside a fixed price

Here is the part that trips up nearly everyone. In Texas, four different contract structures can all be sold to you as "fixed pricing." They differ in how three components are treated: congestion, line losses, and ancillary services. The most bundled version rolls all three into the number you sign. The others leave one, two, or all three to be passed through at cost, which means the real total lands on a later bill. Every one of those structures is allowed to wear the word fixed.

So when a buyer says "just give me your fixed price," they think they are asking one clear question. They are actually asking four different suppliers to answer four different questions, and then they compare the answers as if they matched. A supplier who wants to win on the headline number simply moves a component out of the price and passes it through. The bid drops. The buyer smiles. The cost did not go anywhere.

One aside, since it trips people up. ERCOT is an energy-only market. There is no separate capacity charge the way some other grids have one. If a bid shows a line called "capacity" or "demand," that is the utility's delivery charge, not a wholesale capacity cost, and true scarcity pricing is already baked into the energy number through the Operating Reserve Demand Curve.

Bid A wins the beauty contest and loses the actual contract. The buyer who signs A because the front number was lower pays more for three years and finds out in month two, when congestion, line losses, and a volumetric adder they never priced start showing up on the invoice. Reading a bid means putting every component back in the box before you compare, whether the supplier bundled it or not.

Line losses, and the quiet cost of volumetric billing

Line losses are the power that turns to heat on the way from the plant to your meter. You use one hundred units, more than one hundred have to leave the plant, and someone pays for the difference. On an honest fixed bid, that cost sits inside the price. When a supplier passes it through instead, it becomes a line you never quoted, appearing weeks after you signed. It also travels under several names, so a buyer cross-checking their bill against their contract may not realize the loss factor line and the UFE line and the unaccounted-for energy line are all the same thing.

Volumetric billing means a cost is charged as a small adder on every kilowatt-hour instead of a fixed line on the bill. Sometimes that is normal. Sometimes it is where an extra three to four percent of margin goes to hide. A fifth of a cent per kWh looks like a rounding error next to a six-cent energy price. It is nearly invisible on the bid, and it scales with every unit you use. Multiply it by a year, then by a full term, and it stops looking like nothing.

A 0.20¢ per kWh adder is a middle-of-the-road example. Sharper ones run higher and are just as hard to see.

The Winter Storm Uri charges hiding in your rate

After the February 2021 freeze, the state moved to spread the storm's enormous wholesale costs across many years instead of letting them land all at once. The result was roughly three billion dollars in bonds, paid back through two non-bypassable charges that Texas customers now carry: a default securitization charge and an uplift securitization charge. They service old debt. They have nothing to do with the power you will use tomorrow.

Here is why they belong on this page. Suppliers used to pass these charges through as their own labeled lines, which at least kept them in plain sight. More of them now offer to fold securitization and uplift into the fixed rate instead. That creates two problems for a buyer who watches only the headline number. First, it is one more component to check for whether it sits inside the price or gets billed on top, and a bundled bid and a pass-through bid cannot be compared until you know which is which. Second, once the charge vanishes into a single rate, it stops being a line anyone questions. The reason it exists, a specific decision to intervene in the wholesale market after the freeze, quietly fades from view. That suits the people who would rather it be forgotten.

None of this makes a bundled bid wrong. It makes it a bid you have to read closely. Ask each supplier plainly whether securitization and uplift are inside the rate or passed through, get the answer in writing, and only then line their number up against anyone else's.

One charge, several names

Much of what makes bids hard to compare is that the same cost wears a different costume from one supplier to the next. A buyer who thinks they are missing a charge is often just looking at it under a name they do not recognize. Tap any charge below to see its aliases and what it really is. Once you can read past the names, the games get a lot easier to spot.

What a bill looks like when nobody wants you to read it

All of this eventually lands on an invoice. A supplier who wants to be understood groups it plainly: the utility's delivery charges in one place, the supply you shopped in another, taxes at the bottom. Some suppliers do the opposite on purpose. The example below is modeled on a real bill. It drops regulated delivery, competitive supply, a margin adder, and government taxes into one flat list with no headings, splits the "fixed" energy rate into three different numbers, prints ancillary services twice under two names, and tucks an index charge into a product that was sold as price-locked. Read as printed, it is close to unreadable. That is the point of it, not an accident.

Two of these buckets are not where a supplier makes its money, and should never be confused with the supply you shopped. Regulated delivery is set by your utility and passed through at cost, the same on any supplier's bill. Taxes belong to the state and your city, with the supplier acting only as the collector. Strip those two out and the competitive supply, the only part that ever varied between bids, is sitting right there. On this bill it was arranged so you could not find it, split across three lock rates with an index charge and a plain retail adder mixed in. That is where this supplier quietly padded the number, and a buyer who shopped on the headline rate alone had no way to see it coming. Our bill explainer walks each of these lines in detail, one at a time.

The usage band nobody reads

Even a truly all-in fixed price has a condition attached that price-only buyers almost never check. The rate is only guaranteed to cover a range of usage, called the bandwidth or swing. Stay inside the band and you pay your fixed rate. Drift outside it, in either direction, and the difference gets settled at whatever the market is doing that month, which can sit well above the number you locked. Slide your usage below to see it.

Businesses grow, shrink, add a shift, close a site, or run harder through a hot summer. A buyer who negotiated hard on the rate and ignored the band can win the price and still get a nasty settlement bill the first time reality drifts from the volume they guessed at signing. The band is not a footnote. It is part of the price.

The fixed rate that was never really fixed

A fixed price only holds if the supplier does the unglamorous work behind it. To promise you one rate for three years, they have to buy the wholesale power ahead of time to cover it. That is called hedging, and it costs money. Some suppliers skip part of it, or all of it. They sell a rate below what anyone else can offer, collect the difference while the weather stays mild, and quietly carry the bet that no extreme event shows up before your contract ends. That suspiciously low number is not a sharper supply deal. It is an unhedged position, and you are the one standing behind it.

Then an event arrives, a deep freeze now, and in earlier years a long brutal summer. Demand surges, supply tightens, and wholesale prices run to the system-wide offer cap, thousands of dollars per megawatt-hour against a normal price closer to forty. During Winter Storm Uri in 2021 that cap sat at nine thousand dollars for the better part of a week. A supplier that never bought the power to back your rate now has to buy it at that level in real time while still billing you the cheap rate it sold you. A thin balance sheet does not survive that. The supplier defaults, ERCOT removes it from the market, and its customers get handed off to a provider of last resort. After Uri, a whole wave of retail providers went under in exactly this way.

For the customer, that is the worst possible moment. Your fixed contract is simply gone. The provider-of-last-resort rate is market-based and carries a premium, often several times what you had been paying. You are back in the market days after a price spike, when forward prices are still high and suppliers are skittish. The buyer who signed the lowest number did not lock in a bargain. They bought a promise with nobody funded to keep it, and the bill came due at the one time it hurt most.

You cannot see a supplier's hedge book from the outside. What you can look at is whether a rate sits well below everyone else's for no clear reason, and who actually stands behind it: a supplier with its own generation, a real balance sheet, and years in the market, against a lightly funded reseller that competes on price alone. Sorting that out is a large part of what vetting a supplier means, and one more reason the lowest number on the page and the safest contract are rarely the same line.

When the buyer tries to be the broker

The most confident version of the price-only buyer decides to cut out the middleman. Call five suppliers, capture the broker margin for themselves, pocket the difference. It feels shrewd. It usually costs them money.

Going direct, a buyer gets rate-card pricing built for people who do not know what to normalize. They collect quotes over two weeks, so nothing is comparable. They have no read on where the market sits in its seasonal cycle, so they cannot tell a good day to lock from a bad one. They have no way to tell a clean all-in bid from a stripped one, no leverage to hold a supplier to a same-day number, and no benchmark to know whether any of it is fair. The inside sales desk on the other end of the phone does this every single day. The buyer does it once every three years. It is not a fair fight, and the person who thinks they won it is exactly the person a sharp desk hopes to hear from.

This is the entire reason a firm like ours exists. We solicit multiple suppliers on the same day, so the comparison is real. We put every bid back in the box and normalize it to one all-in number, so the headline games stop working. We read the band and confirm how congestion, losses, and ancillaries are treated before you sign, not after. And we tell you where the market sits in its cycle, so locking is a decision and not a guess. Our compensation is built into the fixed price the same way the winning supplier's own inside sales cost is, so it is the competitive process, not a separate invoice, that sets your number. A disciplined process routinely beats what a headstrong buyer negotiates alone, which is the opposite of what most people expect.
