How Texas Retail Choice Works When You Shop Plans
Shopping for electricity in Texas feels unlike shopping almost anywhere else in the United States. In much of the state you do not buy power from the company that owns the poles outside your house. You pick a retail seller, compare plan documents that look like nutrition labels, and lock in a price for months or years—or you get rolled onto a month-to-month rate if you ignore the expiration notice. That split between who sells the energy and who delivers it is the core of retail choice. Getting it right can save real money. Getting the site, the plan type, or the fine print wrong is how people overpay for the same electrons on the same wires.
What retail choice actually changes on your bill
Retail choice—also called customer choice or electric deregulation at the retail level—means you can select an alternate company to sell you electricity while your local wires company still delivers it to the meter. The ¹ describes the split plainly: the alternate supplier markets or generates the energy; the distribution utility still delivers it and charges for that delivery service.
In Texas, the split is sharper than in most choice states. Inside the ERCOT region, customers of investor-owned utilities must buy from a competitive retail electric provider or be assigned one; participation is not an optional add-on the way it is in many other states, according to the ². Your monthly bill still blends energy charges and delivery charges. What you shop for is mainly the retail energy product—the rate, contract length, fees, and any renewable content—while regulated delivery rates for poles, wires, and metering ride along.
That matters for small businesses as much as households. A bakery and a home office may share the same TDU territory and see similar delivery line items, yet pick different retail products based on usage shape, credit needs, or appetite for price risk. The electrons are a commodity. The contract is not.
The cast of characters: REP, TDU, ERCOT, and the PUC
Four names show up on every competent shopping checklist.
A Retail Electric Provider (REP) is the company you pay for electricity. REPs buy power in wholesale markets, design plans, set rates, and send bills. ³, the state’s largest delivery company, puts it this way: in most of Texas you choose the REP that sets your rates and plans; Oncor does not sell power, set your plan, or send the monthly electric bill.
A Transmission and Distribution Utility (TDU)—also called a wires company or TDSP—owns the poles, wires, and meters. It reads meters, maintains the network, and restores outages. Delivery charges on your REP bill reflect regulated rates the TDU charges the REP for delivery; ⁴ notes those delivery rates are approved by the Public Utility Commission of Texas. In the Houston area, ⁵ likewise states that a retail customer must purchase power and energy from a designated REP while CenterPoint provides delivery service in its territory.
ERCOT—the Electric Reliability Council of Texas—runs the grid that serves more than 27 million customers, about 90 percent of the state’s electric load, and administers retail switching for millions of premises in competitive areas, according to ⁶. When you switch REPs, ERCOT is the registration hub that keeps customer-provider relationships straight so you do not lose service mid-switch.
The Public Utility Commission of Texas (PUCT) licenses and oversees REPs, runs consumer protections, and operates the official shopping site. ⁷ states that if you live in the ERCOT region and are not served by a cooperative or municipally owned utility, you can choose your electric provider—and points shoppers to Power to Choose.
Outages still go to the wires company, not the brand on your marketing email. ⁸ is explicit: call your local TDU for interruptions; reliability of delivery stays with the regulated wires company regardless of which REP you picked.
Who can shop—and who still has a monopoly utility
Not every Texan shops. ⁸ explains that the 1999 deregulation law opened choice in most of the state to encourage competition, but municipalities and cooperatives were not required to deregulate. Enter your ZIP on the Plans page—or call 1-866-PWR-4-TEX—to see whether choice exists where you live.
⁹ adds useful geography. Senate Bill 7 unbundled investor-owned utilities and launched retail competition on January 1, 2002. Municipally owned utilities and cooperatives could opt in; most did not. Those non-opt-in areas—including places like Austin and San Antonio and many smaller communities—do not offer a choice of retail providers. ERCOT estimates that roughly 85 percent of Texas electricity consumers can choose a REP, covering major metros such as Dallas–Fort Worth, Houston, Corpus Christi, Galveston, and Waco. EIA reporting has similarly noted that ERCOT covered the large majority of Texas residential customers in competitive choice territory and that those customers must choose a supplier or be assigned one (¹⁰).
If you are in a municipal system, shopping looks different. ¹¹, a City of Austin utility, publishes a tiered residential tariff with a customer charge, energy charges that rise with usage tiers, a power supply adjustment, community benefit charges, and a regulatory charge. You do not pick among competing REPs; you manage usage, efficiency, and optional green products inside one regulated rate design. That is the regulated-market experience in miniature: one utility, published rates, less plan roulette—and no Power to Choose catalog.
How to shop on Power to Choose without getting lost
Start at the official site. ¹² is the PUCT’s “official and unbiased electric choice website,” open to providers to list offers for free. The ¹³ warns that look-alike sites use similar names; Power to Choose is the one affiliated with the commission. A later Chronicle investigation found brokers adopting “Power to Choose” language in search ads, confusing shoppers into commission-driven sites (¹⁴). Bookmark ¹², confirm the PUCT branding, and be skeptical of near-clones.
The site’s ¹⁵ walks the practical workflow: enter your ZIP; estimate average monthly usage from past bills (usage spikes in months like August and February); filter by price, contract length, prepaid status, time-of-use pricing, renewable percentage, and provider; then refresh results. It also surfaces complaint-based satisfaction signals. The guide’s last step is non-negotiable: open the fact sheet and read it before you enroll.
That fact sheet is the Electricity Facts Label (EFL)—standardized pricing and contract information so you can compare offers apples to apples, as the ⁸ describes. Pair it with the Terms of Service agreement (your actual contract) and the “Your Rights as a Customer” disclosure. Advertised cents-per-kWh on a search results page are a starting line, not a finish line. Narrow to a short list, then read documents.
For a move-in in Oncor territory, the delivery utility’s process is: find the premise’s ESI ID, choose a REP (or call Texas Electric Choice at 1-866-797-4839), give the REP the last seven digits of the ESI ID, and let the REP send the move-in order (¹⁶). You do not call Oncor to “buy power”; you buy from the REP and Oncor energizes delivery.
Rate designs that look cheap until you read the fine print
Fixed-rate plans lock a price for a term longer than one month; variable-rate plans can change month to month, as the ¹⁵ notes. Fixed rates are useful when you want bill predictability through summer heat or winter cold snaps. Variable rates can look attractive on a teaser month and then climb; the Chronicle primer advises checking historical rate links on the EFL and notes that many advocates prefer some certainty over pure market exposure (¹³).
Minimum usage fees punish low use. If you use less than a threshold—often discussed around 500 or 1,000 kWh—you may owe an extra charge even though you conserved. The ⁸ says those fees may not appear as a clean line item and that the EFL is where you verify them. Apartment dwellers and efficient small homes should treat minimum-usage plans as guilty until proven innocent against their actual monthly kWh history.
Tiered and time-of-use products change the price based on how much you use or when you use it. Filters on Power to Choose exist specifically so you can exclude minimum-usage and tiered plans if you want a cleaner comparison (¹⁵). “Free nights and weekends” can raise weekday rates enough that the gift of free hours is no gift at all for a conventional work-from-home schedule (¹³).
Prepaid plans are another category the site lets you filter. Consumer advocates quoted in the Chronicle primer argue prepaid products often carry higher per-kWh rates and fee stacks and weaker disconnection notice protections—worth extreme caution unless your credit situation leaves few alternatives.
Bill credits and freebies—thermostats, gift cards, team gear—are marketing. Watchdogs in that same primer argue your annual energy spend usually dwarfs the swag; shop the all-in cost at your usage, not the prize.
Finally, brand familiarity does not restore power faster. In Houston, CenterPoint restores outages regardless of REP brand; what varies is customer-service complaint history visible on Power to Choose (¹³).
Switching, move-ins, renewals, and your rights
You can choose a new plan or company at any time, but breaking a fixed contract can trigger early termination fees—review your Terms of Service. There is no PUC switching fee unless you request a special meter reading off the normal cycle (⁸). After you enroll, ERCOT mails confirmation; you have three business days to change your mind. The switch typically completes within seven business days with no service lapse, and you do not have to call your old REP—the new one and ERCOT handle the handoff—though you remain responsible for any early-exit penalties (⁸).
Contract expiration notices are a shopping alarm clock. Providers must warn residential customers before a term ends; if you do nothing, you can land on a month-to-month variable product that is rarely the cheapest long-term option (⁸; ¹³). Reporting on PUC rules has noted that residential customers can switch without an early termination fee if they time the switch no earlier than 14 days before the expiration date in the notice (¹³); confirm the timing in your expiration letter and Terms of Service before you act.
Customer rights include protection against slamming (switching without permission) and cramming (unauthorized add-on charges), non-discrimination rules, privacy limits on sharing customer-specific data, Spanish-language materials where required, and a PUC complaint path at 1-888-PUC-TIPS (⁸). If a REP exits the market, you should get advance notice in most cases; if not, service moves to a Provider of Last Resort rather than going dark—then shop again promptly, because POLR service is a safety net, not a destination plan (⁸).
Disconnection for nonpayment is real: expect a termination notice with a window to pay or arrange payment (⁸). Treat deposits, late fees, and paper-bill fees as first-class shopping criteria, not afterthoughts.
Outside Texas: voluntary choice markets and regulated bills
Texas is the extreme case because choice is mandatory for eligible ERCOT IOU customers. Elsewhere, retail choice is usually voluntary. The ² counts nineteen states plus D.C. with some commercial and industrial choice, and fifteen of those states plus D.C. with choice across sectors—and notes that outside ERCOT, customers can stay with the default utility supply. Nationally, residential participation in choice programs has been modest as a share of all U.S. households, peaking near 17 million customers around 2014 (¹⁰).
Ohio is a useful contrast: it opened a full retail market after a long transition and has been among the leaders in residential choice enrollment outside Texas, though participation dynamics shift with prices and supplier events (¹⁰). In many Midwestern and Mid-Atlantic choice territories, the local utility still delivers power and often still prints a consolidated bill that separates supplier charges from delivery charges—similar unbundling, different default rules. Wherever you are, the practical shopping advice is the same: confirm whether your address is eligible, contact your distribution utility or state commission for supplier lists, use any state-sanctioned shopping portal when one exists, and read the contract for early-exit fees and variable-rate reset language (¹).
If you live in a fully regulated market—or a Texas municipal/co-op area—you still have decisions, just different ones: rate class, demand charges for small business, time-of-use pilots, efficiency rebates, and budget billing. Compare your bill’s line items to the utility’s published tariff the way Austin Energy customers can match charges to the residential rate page (¹¹). Shopping skill transfers: know your kWh, know your fees, know who to call for an outage.
A practical decision checklist
- Confirm eligibility. ZIP code on ¹² or your state commission site. No choice? Work the regulated tariff and efficiency levers instead.
- Gather usage. Twelve months of kWh if you can; otherwise expect seasonal swings and avoid plans that only “win” at 500 / 1,000 / 2,000 kWh display points.
- Use the official portal. Prefer ¹² in Texas; treat look-alikes as ads until proven otherwise (¹⁴).
- Filter ruthlessly. Fixed vs variable, term length, prepaid off unless necessary, minimum-usage and tiered plans off unless your usage clearly fits (¹⁵).
- Read the EFL and Terms of Service. Every non-obvious fee should be explainable in one sentence before you click enroll (⁸).
- Check complaint history and renewable content if those matter to you—both are filterable on the official site.
- Time switches to contract ends when you are in a fixed term; calendar the expiration notice so you do not auto-roll to a costly month-to-month product.
- Save outage numbers for the TDU, not the REP marketing line (⁸).
- For move-ins, have the ESI ID ready and let the REP issue the order (¹⁶).
- Escalate disputes to the REP first, then the ⁷ at 1-888-782-8477 when needed.
Retail choice does not make electricity less physical. It makes the commercial layer competitive. In Texas that competition is deep, documented, and easy to misuse. The winning move is boring on purpose: official site, real usage, fixed clarity when you need it, documents read end to end, and a calendar alert before every contract expires. Do that, and the market works more like a tool than a trap.
