Data sources

The core dataset

We maintain an independent plan-intelligence feed originating from the official plan-export feature on Power to Choose (powertochoose.org), the Public Utility Commission of Texas's own electric-choice comparison site. It tracks filed rates by delivery utility and preserves official Electricity Facts Label links for research, provider and utility content, monitoring, and a future fallback comparison system. It does not define which plans are currently available inside our live marketplace.

Electricity Facts Label enrichment

Every plan is legally required to publish an Electricity Facts Label: a standardized disclosure with the real energy charge, base charge, contract term, and exact termination-fee language. We went a step further and read a historical subset of those documents. The old “80 of 138” result describes one archived July 2026 sample; it is not current coverage and should not be used to judge today's plan universe. New daily feed rows begin as not checked unless a matching previously verified Electricity Facts Label can be carried forward by the same official URL. Every static sample links to the official Electricity Facts Label, and an unreviewed or automation-resistant document remains labeled honestly rather than receiving invented enriched terms.

The ZIP-to-delivery-utility map

Which company delivers electricity to a given address (Oncor, CenterPoint, etc.) isn't something Power to Choose's export tells you directly: pricing there is organized by delivery utility, not ZIP code. We built our ZIP-to-TDU crosswalk separately, directly from each delivery utility's own published service-territory ZIP list. Some ZIP codes genuinely straddle more than one utility's territory; where that's true, we ask which utility serves your specific address rather than guessing, because the same plan can be priced differently depending on which TDU actually delivers your power.

How current is this data, really?

The independent KV feed refreshes daily and is served only while its recorded timestamp is fresh. That refresh supports monitoring and research, but it does not rewrite static provider, utility, city, blog, or guide pages. Static plan samples therefore carry their own checked date and are regenerated only after Electricity Facts Label-link review and a controlled site deployment.

The I Moved to Texas marketplace is separate from this research feed. Our marketplace partner controls the live inventory, pricing, address validation, checkout, and enrollment shown there. A fresh independent feed is not proof that the same offer appears in the marketplace, and a marketplace offer is not proof that we independently parsed its Electricity Facts Label. Prices, availability, and terms can change, so always confirm the current Electricity Facts Label and final checkout terms before enrolling.

Possible gaps and errors

• Deposit requirements are not disclosed in our current source export for any plan: we flag this honestly rather than assume "no deposit."
• The statewide independent export is organized by delivery utility, not exact ZIP or address; address-level eligibility must be verified separately.
• The bill-credit flag on a plan is a heuristic based on matching plan name and terms text, not a fully structured field: it's possible for an unusually worded plan to be missed.
• Electricity Facts Label automation can fail on dynamic viewers, authentication, or bot protection; those links require manual review and remain unparsed until verified.
• Providers add, remove, and change plans continuously; a dated static sample is historical context, not present-moment inventory.

Authoritative sources, if you want to verify anything yourself

• Public Utility Commission of Texas: the state regulator overseeing retail electric choice.
• Power to Choose: the PUCT's own official plan-comparison site and the origin of our core dataset.
• Internal Revenue Service: current termination rules for the federal residential clean-energy credit.
• Texas Comptroller: the solar and wind-powered energy-device property-tax exemption and Form 50-123.
• Oncor Residential Solar Program: current territory, equipment, contractor, and interconnection requirements for that utility's program.
