This October, a mild week of open windows will drop some Texas home from 1,010 kilowatt-hours to 985 — and raise its electric bill by $125.
No late fee, no penalty, no rate hike. Frontier Saver Plus 12 pays a $125 bill credit in any month you use 1,000 kilowatt-hours or more, and pays nothing — not a prorated dime — at 999. Twenty-five kilowatt-hours of easing off the AC can be the whole difference.
This page is the math behind that line, pulled straight from the plan’s pricing fact sheet (the EFL), plus an honest answer to the question the plan’s name begs: does Saver Plus actually save you money?
Rates checked August 6, 2026, against Frontier’s current EFLs for all five Texas delivery areas (dated July 28 – August 1, 2026).
The deal on the label
Frontier Saver Plus 12 shows up on rate tables with one of the lowest advertised prices in Texas — 7.1¢ per kilowatt-hour in the AEP Central delivery area, and as low as 6.5¢ in Houston, per the current EFL (dated July 30, 2026). Here’s what’s underneath that number, from the same document:
- Energy charge: 13.58¢ per kWh. What Frontier actually charges for every unit of power.
- Delivery charges: 5.69¢ per kWh plus $3.24 a month. Pass-through fees to your local wires company (the TDU) — the same on every plan.
- Usage credit: $125 per billing cycle when usage hits 1,000 kWh or more. Nothing below that.
The real rate is 13.58¢ plus delivery — call it 19 cents and change, all in. Not cheap. The entire “cheapest plan in Texas” story rests on the $125 credit. And the credit rests on a single number: 1,000.
The rest of the label, at a glance — all from the current EFLs:
| The fine print | What it says |
|---|---|
| Plan type | Fixed rate, 12 months, bill-credit structure |
| Frontier’s base charge | $0 a month (TDU delivery charges pass through) |
| Bill credit | $125 every billing cycle at or above 1,000 kWh; $0 below |
| Cancellation fee | $150 — waived if you move and show proof |
| Renewable content | 30.4% (the statewide average is 33.3%) |
| Billing | Paperless only — keep a valid email on file or fees can apply |
| Escape hatch | 60-Day Happiness Guarantee: one free swap to another Frontier plan |
The exact figures shift a little between delivery areas, but the structure is identical everywhere Frontier sells this plan. Here’s the plan’s own three-tier price disclosure across Texas, straight from each area’s EFL:
| Delivery area | 500 kWh | 1,000 kWh | 2,000 kWh |
|---|---|---|---|
| CenterPoint (Houston) | 19.5¢ | 6.5¢ | 12.5¢ |
| Oncor (Dallas–Fort Worth) | 20.2¢ | 7.3¢ | 13.3¢ |
| AEP Central (Corpus Christi) | 19.9¢ | 7.1¢ | 13.2¢ |
| AEP North (Abilene) | 21.2¢ | 8.4¢ | 14.5¢ |
| TNMP | 22.2¢ | 8.9¢ | 14.8¢ |
Average price per kWh from Frontier’s EFLs dated July 28 – August 1, 2026. Same cliff in every row: the left column is roughly triple the middle one.
The math at the edge of the cliff
Two bills, priced with the AEP Central EFL’s own numbers. Say your billing cycle closes and the meter reads exactly 1,000 kWh — the sweet spot:
- Energy: 1,000 × 13.58¢ = $135.80
- Delivery: $3.24 + 1,000 × 5.69¢ = $60.14
- Credit: −$125
- Total: about $71. Average price: 7.1¢.
Now say the meter reads 999:
- Energy: 999 × 13.58¢ = $135.66
- Delivery: $60.08
- Credit: $0
- Total: about $196. Average price: 19.6¢.
One kilowatt-hour less. $125 more. No proration, no partial credit, no close-enough. The EFL says it without blinking: “There is no Usage Credit for a billing cycle when usage on this plan is below 1000 kWh.”
Put those months next to a plain fixed-rate plan and the shape of the product jumps out. The Saver Plus column is computed from the EFL above; the fixed column is our illustration at 14¢ all-in — a middling plain rate, given that Texas fixed plans mostly land between 12¢ and 16¢ as of August 2026:
| Your month | Saver Plus | Plain 14¢ fixed (illustration) |
|---|---|---|
| 500 kWh — apartment | ~$100 | ~$70 |
| 999 kWh — missed by one | ~$196 | ~$140 |
| 1,000 kWh — hit the floor | ~$71 | ~$140 |
| 1,500 kWh — summer | ~$167 | ~$210 |
The cliff has a second face, too. The credit is a flat $125, so the more you use past 1,000, the less it matters. At 2,000 kWh, the same EFL puts the average at 13.2¢ — nearly double the headline. At 500 kWh: 19.9¢, apartment territory, and the worst deal on the page.
So the sweet spot isn’t “1,000 or more.” It’s a narrow band sitting right at and just above 1,000 kWh — and your usage has to land in that band twelve months in a row.
Three numbers give the cliff away
You don’t need to decode the fine print to spot a credit cliff. Every EFL opens with the same three-column table: the average price at 500, 1,000, and 2,000 kWh. Saver Plus prints 19.9¢ — 7.1¢ — 13.2¢.
On a plain fixed-rate plan, those three numbers sit within a penny of each other. When the middle number is a third of the left one, you’ve found a cliff — and the advertised rate only exists for people whose meter lands on the magic number.
Thirty seconds, three numbers. That test works on every bill-credit plan in Texas, not just this one.
The month that gets you
Nobody falls off this cliff in August. A Texas summer pushes almost any house past 1,000 kWh without trying. The credit lands, the bill looks great, and Saver Plus feels like the smartest thing you signed all year.
The bill that gets you arrives in April. Or October. Mild weather, windows open, the AC finally resting — and a typical house drifts down to 700–900 kWh. The credit vanishes, and you’re paying nearly 20¢ effective for your lightest month of the year.
Notice what that means: the plan is cheapest when the weather is brutal and you’re using the most power, and most expensive when the weather is gentle and you’re using the least. Your reward for conserving is a higher rate. That’s not an accident — it’s the shape of the product.
Here’s a full year, as an illustration. Say your house averages about 870 kWh a month — a smaller Texas home — clearing 1,000 kWh only in June through September. Four credits at $125 sounds like $500 in free money.
Run every month through the EFL’s prices and the year totals roughly $1,550 — about 15¢ per kilowatt-hour average. Not 7.1¢. Not close. The eight months without a credit quietly ate the four months with one, and that boring 14¢ fixed plan from the table above would have cost about $90 less.
The smaller your home, the worse the trade. And the people most likely to sign — apartment renters who saw a 6.5¢ headline at the top of a rate table — are the people the math treats worst.
Frontier’s 60-Day Happiness Guarantee is a real safety net: one free swap to another Frontier plan in your first 60 days. But most people sign up in summer, when every month clears the floor. By the time the first mild month exposes the cliff, the window closed months ago.
Frontier isn’t the villain here
Let’s be fair, because it matters: Frontier Utilities is a good electric company. It’s owned by NextEra Energy — the largest energy company in North America — has sold power in Texas since 2008, and routinely prices 20–30% under TXU and Reliant. We say as much in our Frontier Utilities profile, and Frontier wins plenty of our head-to-heads, including TXU vs Frontier and Reliant vs Frontier.
The problem is the structure, and it’s an industry habit, not a Frontier invention. A big chunk of the Texas market plays some version of the bill-credit game. TXU dresses the same trick up as free days. Gexa — Frontier’s sister brand under NextEra — runs a credit cliff of its own (Gexa vs Frontier).
Even inside Frontier’s lineup, Saver Plus is the middle child of a whole family built this way: Saver Value plans put the credit floor down near apartment-sized usage, and Saver Deluxe and Premier push it higher for big homes. Same cliff, different altitude. If a Frontier plan tempts you, match the floor to your usage — not the name.
Why does the credit exist at all? Because rate tables sort by the advertised average at 1,000 kWh. A $125 credit aimed precisely at that number buys the top of every list. The plan isn’t designed around your house. It’s designed around a sort order.
Is Saver Plus ever a good deal?
Yes — genuinely, for the right house.
If your home clears 1,000 kWh every month of the year — all twelve, not just the summer — Saver Plus is one of the cheapest ways to buy electricity in Texas right now. Bigger homes, pool pumps, electric heat, full households: if your lightest month runs 1,050 kWh or more, the credit shows up on every bill and the 7.1¢ story is your actual life.
Here’s the break-even in one line: a month that hits 1,000 kWh saves you roughly $70 against a mid-priced fixed plan, and a month that misses hands most of that back — $56 at 999 kWh, about $40 at a light 700 — so the fewer months you’re sure of, the faster this plan’s edge evaporates. (The figures come from the bill table above, recomputed at 700 kWh.)
The test takes five minutes: pull your last 12 months of usage from any bill or your online account, and find your lowest month.
- Lowest month at 1,050 kWh or above? The plan fits. Take the cheap rate and don’t look back.
- Any month under 1,000? The math flips. Every one of those months, you pay roughly 20¢ effective — and a plain fixed-rate plan a cent or two higher at headline will beat Saver Plus on total yearly cost for most homes.
If you don’t know your usage, that’s your answer too. This plan punishes guessing.
What to do instead
- Get your real usage. Twelve months of it — from an old bill, your online account, or Smart Meter Texas. Write down your lowest month.
- If that lowest month is under 1,000 kWh, skip credit plans entirely. A boring fixed rate with no floor will cost less across the year, even when its headline number looks worse.
- Compare at your actual usage on ComparePower. Enter your usage and the prices are computed at your number, credits and all — including Frontier’s own plans, some of which fit small homes far better than Saver Plus does.
- Weighing Frontier against the big brands? Start with TXU vs Frontier or Reliant vs Frontier. Frontier often wins — just usually on a different plan than this one.
A $125 credit is not a gift. It’s your own money, collected at 13.58¢ a kilowatt-hour and handed back only if your meter cooperates.
