The plan behind the name
People search this plan by name, so start with what the name is selling. Frontier Utilities Saver Plus 12 advertises one of the lowest averages on the Texas shelf: 7.3 cents per kWh at 1,000 kWh in Oncor territory as of August 2026. Frontier itself is a real company, with main offices in Dallas and Houston per its own site, PUCT certificate 10169, and a 60-day Happiness Guarantee. None of that is the story.
The story is the pricing. The rate you sign is 13.3 cents per kWh, every hour, every kilowatt-hour, plus delivery charges. The 7.3 cent average exists because a $125 bill credit lands in any billing cycle where you use 1,000 kWh or more, and the advertised number is computed at exactly that point. Use 999 kWh and the credit is zero. The month you conserve is the month the plan charges you most.
And Saver Plus is not only Frontier's plan. Gexa Energy sells the identical structure as Eco Saver Plus 12: same 13.3 cent energy charge, same $125 credit at the same 1,000 kWh line, same $150 cancellation fee, bills identical to the penny at 500, 1,000, and 2,000 kWh in our August 7, 2026 feed pull. Both brands answer to the same parent, NextEra Energy. We tore down the shared engine and the ownership trail in our Gexa Eco Saver Plus review; this page covers the Frontier side of the same machine.
Claims vs. fine print
Four claims on the front. Four footnotes on the back. Here they are, side by side.
The mailer says
An advertised average of 7.3 cents per kWh at 1,000 kWh (Oncor, as of August 2026).
The fine print says
The rate you sign is 13.3 cents per kWh plus Oncor delivery charges (6.0 cents per kWh and $4.06 a month). The 7.3 is arithmetic, not a price: the $125 credit lands at exactly 1,000 kWh and drags the average down at that one point. At 500 kWh the same plan averages 20.2 cents. At 999 kWh, 19.8 cents. At 2,000 kWh, 13.3 cents.

The mailer says
A "$125 bill credit" in months you use 1,000 kWh or more.
The fine print says
All or nothing, decided monthly. Use 1,000 kWh and the full $125 appears; use 999 and you get zero. No partial credit, no proration, and every billing cycle starts the count over. A strong August does nothing for a mild October.

The mailer says
A Frontier plan, from an independent Houston company you can comparison-shop against the big names.
The fine print says
The engine is not exclusive to Frontier. Gexa Eco Saver Plus 12 carries the identical energy charge, credit, threshold, and cancellation fee, and prices to the penny at every usage level in our August 2026 feed. NextEra Energy has owned Gexa since 2005 and took over Frontier in a deal reported in January 2019. Comparing these two brands is checking one spreadsheet twice.

The mailer says
A 60-Day Happiness Guarantee: switch plans within 60 days if it is not working out.
The fine print says
Real, and worth using if you discover the cliff early. But the hatch opens onto Frontier's own shelf, where five of the six Saver-family plans in our August 2026 Oncor feed are bill-credit plans with thresholds at 500, 750, 1,000, 1,500, and 2,000 kWh. Swapping cliffs is not escaping cliffs.

The rate is public. The average is built.
Every number here is checkable. Frontier publishes the Electricity Facts Label after you enter a ZIP code on its site, and the plan prices in marketplace feeds including ours. What you pay in Oncor territory as of August 2026: an energy charge of 13.3 cents per kWh, no REP base fee, Oncor's delivery charges passed through (6.0 cents per kWh plus $4.06 a month), and one conditional line: $125 off any billing cycle of 1,000 kWh or more.
The advertised average moves by territory because the delivery charges, and Frontier's energy charge itself, shift with the wires company. At 1,000 kWh, Saver Plus 12 averages 6.5 cents in CenterPoint territory, 7.1 in AEP Central, 7.3 in Oncor, and 8.9 in TNMP as of August 2026. Every one of those numbers is computed at the credit's exact landing point. Step off the point and the same plan runs 19.5 to 22.2 cents at 500 kWh depending on territory.
Here is the number that exposes the engine. The cheapest flat, no-gimmick plan in Oncor territory costs 12.8 cents all-in at 1,000 kWh as of August 2026. Saver Plus's energy charge alone is 13.3 cents, before delivery is even added. Strip the credit away and this plan loses to the boring option at every usage level. The credit is not a bonus on top of a good rate. The credit is the entire pitch.
Saver Plus is sold at frontierutilities.com, with the Electricity Facts Label shown after you enter a ZIP code, and through marketplace feeds including ours. It did not appear in the Power to Choose results we pulled for a Dallas ZIP in August 2026; Frontier listed its Power Saver plans there instead. If you enroll, pull 12 months of your own usage first and count how many months fall below 1,000 kWh.
How the $125 credit works
The mechanism is one sentence long: if your usage in a billing cycle is 1,000 kWh or more, $125 comes off that bill; anything less, nothing does. A 999 kWh month earns the same credit as a zero kWh month: none. Each cycle stands alone. The energy charge, delivery charges, and taxes are untouched either way.
There is no ceiling on the other side. A 2,000 kWh month gets the same $125 spread across twice the usage, which is why the average climbs back to 13.3 cents. And you do not control which side of the line you land on. Weather does, and so does your meter-read calendar. A cool spring, a two-week trip, a billing cycle that closes a few days early: any of these pulls a month under 1,000 kWh, and you find out which side you landed on when the bill arrives. This is the standard trap of the bill-credit class, and it cuts both ways at every threshold.
Do the math on a Frontier bill
Two bills define this plan, priced in Oncor territory as of August 2026. Use 999 kWh: no credit, $197.60, a 19.8 cent average. Use 1,000 kWh: credit lands, $72.80, a 7.3 cent average. About twenty cents' worth of electricity swings the bill by $124.80.
Now score it against the boring alternative. On the market's cheapest flat plan, 12.8 cents all-in at 1,000 kWh, that month costs about $128.30. A Saver Plus month that hits the threshold saves you about $55.50 against that. A month that misses at 999 kWh costs you about $69.50 more. Every miss erases a hit, and then some. To come out ahead over a full year you need clearly more hit months than miss months, and Texas shoulder seasons vote against you every spring and fall.
Place a real home on that curve. The average Texas household used 1,096 kWh a month in 2024, per the U.S. Energy Information Administration. That average is built from Julys far above the line and Aprils below it. So run the honest test before signing: pull your own 12 months of usage and count the months under 1,000 kWh. That count, times roughly $69.50, is what this plan's bad months cost. Neither Frontier's site nor any marketplace will run that count for you.

Fine print, decoded
The five footnotes on the back of the mailer, translated into plain English.
| What the footnote says | What it means |
|---|---|
| $125 usage credit applies in billing cycles with usage of 1,000 kWh or more. | All or nothing, every month. 999 kWh earns zero, and each cycle starts over. The months you conserve, travel, or get mild weather are the months the credit walks away. |
| Energy charge of 13.3 cents per kWh plus Oncor delivery charges (6.0 cents per kWh and $4.06 per month), passed through without markup. | Without the credit this is a losing flat plan: its energy charge alone, 13.3 cents, tops the cheapest no-gimmick Oncor plan's entire all-in price, 12.8 cents at 1,000 kWh as of August 2026. Everything you might save rides on hitting the threshold. |
| 12-month term. Early termination fee: $150. | Discover the cliff in month three and it costs $150 to leave, unless you use the 60-day guarantee first. Our feed carries the 12-month version; if you are quoted a longer-term Saver Plus, read its EFL before signing, especially the exit fee, which typically grows with the term. |
| Renewable content: 30.4%. | The identical plan on Gexa's shelf is 100% renewable at the same price, backed by renewable energy credits. Same engine, same bills, different paint. If the green matters to you, the twin gives you more of it for the same money. |
| 60-Day Happiness Guarantee: new residential customers can switch to a different Frontier plan within 60 days of activation with no cancellation fee. | A real escape hatch, but it applies one time only, your contract term restarts with the new plan, and it opens onto Frontier's own shelf, where five of six Saver-family plans are credit cliffs at different thresholds (500 to 2,000 kWh in our August 2026 feed). Read the EFL of whatever you land on as carefully as the one you left. |
The Frontier shelf, and the other name on the engine
Saver Plus is one of six Saver-family plans Frontier listed in our Oncor feed in August 2026, and five of them are bill-credit plans: Saver Value ($50 at 500 kWh), Saver Value Plus ($75 at 750), Saver Plus ($125 at 1,000), Saver Deluxe ($100 at 1,500), and Saver Premier ($150 at 2,000). The sixth, Light Saver 12, skips the credit but carries an $8 monthly base charge on usage under 2,000 kWh. Every plan wears the word Saver. Each one saves a different customer, and costs every other one.
Each of those plans also has a twin on Gexa's shelf. In our August 7, 2026 feed, five of the six price penny-identical to a Gexa Eco Saver counterpart at every usage level we check; the sixth differs by a tenth of a cent. The Gexa versions carry a 100% renewable badge, the Frontier versions 30.4%, and the bills match anyway. The practical effect on you: comparing Frontier against Gexa looks like shopping and is not. The defense is the same as always. Compare plans by their all-in cost at your own usage, not by how many logos you checked. The full ownership story is in the companion teardown.
What to do instead
For contrast, here is the live Oncor market on the day we published (August 2026). The cheapest all-in plan at 1,000 kWh was 7.0 cents per kWh, and it is a bill-credit plan too; the whole class cuts both ways. The cheapest flat plan with no credits and no tiers was 12.8 cents all-in at 1,000 kWh, less than Saver Plus's bare energy charge before delivery is even added. Compare plans at your own usage, including the rest of the Frontier lineup and its Gexa twin, below.
