ChatGPT and other large language models are undeniably among the most important technological inventions since the World Wide Web. Most people are already familiar with how to use these tools to summarize emails, draft resumes, or get general advice. But can you rely on them to navigate the complex Texas electricity market? While AI is brilliant at general tasks, our testing shows mixed results when it comes to finding the cheapest True Fixed rate plan in Texas.
Can ChatGPT help me find the best electricity plan?
The easiest way to answer that question is to test it. For this review, we used:
- ChatGPT (latest model: 5.6 Sol)
Our expectations were simple and reasonable:
- We want to find the cheapest possible electricity rate with no gimmicks or tricks
- Absolutely no bill credit plan, True Fixed-Rate plans only, Contract length: 12 to 23 months Service area: Dallas–Fort Worth (Oncor).
- If the AI cannot accurately identify the best plans, at a minimum we expect it to route us to trustworthy sources.
What Are the Best True Fixed-Rate Plans Right Now?
Before analyzing the results, we need to establish the ground truth. As of August 22nd 2026, the best True Fixed-Rate electricity plans—with no bill credits, no usage thresholds, and no pricing tricks—in the Dallas–Fort Worth (Oncor) area are priced at approximately 11.3¢ per kWh at 1,000 kWh usage:
| Company | Plan | Term | kWh @ 1000 |
|---|---|---|---|
| Varsity Energy | HOMERUN 12 | 12 months | 11.3¢ |
| Octopus Energy | Octo Simple 12 | 12 months | 11.3¢ |
| Energy Texas | No Bull 12 | 12 months | 11.7¢ |
These plans are the best True fixed rates plans right now, you can have a list of the top 10 cheap electricity plans here. this is a curate and validate list that include the options of the website power to choose.
Now Let’s Ask ChatGPT
We asked a very simple question: “Give me the top 3 cheapest fixed rate electricity plans in the Dallas area.”
ChatGPT responded with:
- APG&E — SimpleSaver 12 (~6.80¢/kWh)
- Gexa — Eco Saver Plus 12(~6.9¢/kWh)
- 4Change Energy — Maxx Saver Value 12 (~6.9¢/kWh)
❌ This answer is wrong.
All of these plans are bill credit plans.
They only reach those low advertised rates if you hit a specific usage level (usually exactly 1000 kWh). Miss it by even 1 kWh, and your bill can spike dramatically. As you can see in the table below:

| Company | Plan | Term | kWh @ 500 | kWh @ 1000 | kWh @ 2000 |

| Gexa Energy | Gexa Eco Saver Plus 12 | 12 months | 19.8¢ | 6.9¢ | 13.0¢ |
We Asked Again (More Explicitly)
We clarified: “I don’t want bill credit plans. I want true fixed-rate plans only.”
ChatGPT then responded with something closer to the truth:
- Rhythm Energy — Simply Select
- BKV Energy — Bluebonnet 12
- APG&E — Simple Choice 12
Are these true fixed-rate plans? ✅ Yes.
Are they the cheapest? ❌ No.
Are they the cheapest? ❌ No.
For example, BKV Bluebonnet 12 is a clean True Fixed plan — but it is not among the cheapest true fixed-rate options. It ranks 21 out of 45 plans reviewed (August 2026). It’s a good plan, from a good company. but it is not the best-priced option.
Can You Trust ChatGPT to Avoid Gimmicks?
❌ No. And this is the dangerous part. On the very first question, ChatGPT confidently provided a wrong answer that pointed directly to the type of plans consumers are trying to avoid.
Why does this happen?
ChatGPT (and Gemini) rely on top-ranking search results to find answers. Unfortunately, many of the "authoritative" websites they scrape are built to sell, not to inform. These sites often:
- Rank plans by "teaser" price only, ignoring the real cost.
- Display rates only at 1,000 kWh, hiding price spikes for smaller homes.
- Highlight complex bill credits that look cheap on paper but risk high bills.
- Mislabel bill-credit plans as standard "fixed-rate" options.
When AI models search the web, they see those plans repeatedly listed as the “cheapest.” The models may vaguely mention that a plan could involve bill credits, but they do not reliably filter them out. This creates a real risk: AI can unintentionally guide people straight into the traps they are trying to avoid.
What Is the Best Way to Use ChatGPT for Texas Electricity?
The manual method above works, but it puts the work on you. You still have to find the right list, download the EFLs, and feed them in one by one.
There is now a faster way. ChatGPT does not fail because the model is weak. It fails because the data it finds is bad. The sites it reads rank plans by teaser price and label bill credit plans as "fixed," so the model repeats what it reads. Instead of fighting that with better prompts, we fixed the data.
The Clear Energy Facts plugin is approved and live in the ChatGPT plugin directory. It connects ChatGPT directly to the same plan database behind our city pages: True Fixed filtering, pricing verified against the EFL, and rates at 500, 1,000 and 2,000 kWh instead of only the 1,000 kWh number that hides the spikes.
The plugin only provides properly structured plan data, including a detailed breakdown of rates and charges, so ChatGPT can perform calculations and comparisons accurately.
Along with True Fixed plans, Free Nights and Free Weekends plans are also provided and updated weekly. ChatGPT will have the necessary information, such as the free hours window and whether TDU charges are included during the free period. If you want, you can ask ChatGPT to perform calculations, analyze your uploaded CSV usage data, and compare plans based on your consumption.
This is one of the best ways to use ChatGPT to find the best electricity plan. Without the plugin, ChatGPT may simply search for the lowest advertised rates, which are usually bill credit plans. With the plugin, you give ChatGPT access to properly categorized plans, including Power to Choose offers.
Final Verdict — Should you use ChatGPT to shop for electricity?
- ❌ Not as a search engine
- ❌ Not as a ranking tool
- ✅ Yes — as an EFL analysis assistant
- ✅ Yes — by using Clear Energy Facts Plugin
AI is powerful, but electricity pricing is full of traps, and today's models are only as good as the data they are fed. Unfortunately, the top search results for electricity are plagued by comparison websites that prioritize their own commissions over your savings. A model reading those pages is not being careless. It is repeating the most confident answer available to it, and in this market the most confident answer is usually the one someone paid to put there.
That is the difference between the two red marks and the two green ones above. On its own, ChatGPT inherits the bias of the pages it reads. Given clean data, the same model does the part it is genuinely good at, which is arithmetic and comparison across many variables at once. It will check a plan at 500 kWh instead of only 1,000, read the free hours window against your actual usage, and tell you plainly when the cheap advertised rate depends on hitting a number you will miss half the year.
