Texas Prepaid Electricity: What Pay-As-You-Go Really Costs

Prepaid electricity sounds simple: buy power the way you buy gas for a car, watch the balance tick down, and top up when it runs low. In deregulated Texas, that model is real—and heavily regulated—but the sticker price on a shopping site is rarely the whole story. This guide walks through how pay-as-you-go service works, what drives the true cost per kilowatt-hour (kWh), and how to compare it against a traditional postpaid plan without getting blindsided by fees, delivery charges, or a sudden shutoff.

What prepaid electric service actually is

In Texas, ¹. A retail electric provider (REP)—the company that sells you the energy plan—lets you fund an account balance up front, then draws down that balance as your home uses power. ¹; instead, you get electronic updates on remaining funds and usage, and you can ask your REP for a ¹ of activity.

That cash-flow model is the main product difference. You still need a working meter (typically a smart meter that can report usage frequently), and ¹ for balance and disconnection notices. ¹; if you become designated while on prepaid, ¹ so service is not interrupted mid-crisis.

² that does not require a deposit and does not always include a contract, but that does require timely prepayment and close monitoring. Think of prepaid as a payment and credit product layered on top of the same wires and the same wholesale market that serve postpaid customers. The physics of your air conditioner do not change. What changes is when you pay, how fast you can lose service if the balance bottoms out, which documents disclose fees, and often the effective price you pay for each kWh.

Why Texas retail choice matters for prepaid shoppers

Most of Texas sits inside the ERCOT region, where the ³—and ³. In those competitive areas, you pick a REP for the energy product, while a transmission and distribution utility (TDU or TDSP) owns the poles, wires, and meters that deliver power to your address. You generally cannot shop the wires company the way you shop the REP.

: Oncor owns the delivery system and bills REPs for delivering and metering electricity; REPs then bundle those regulated delivery charges into what customers pay. . , so switching REPs does not erase wires costs—it only changes how the competitive energy piece is priced and billed.

That architecture is why prepaid "true cost" has two layers. Layer one is the REP's prepaid product: energy price, daily or other service fees, payment fees, and reconnection rules. Layer two is TDU delivery, which shows up whether you are prepaid or postpaid. A fair comparison always includes both.

For context on statewide pricing, the U.S. Energy Information Administration reports , while the —below the . Those averages mix regulated and competitive areas and every plan type. They are benchmarks, not a promise that any prepaid offer will land near them.

Power to Choose—the PUCT's official shopping site—also notes that ². That single sentence is the starting point for a true-cost analysis: you may trade a deposit and a credit check for a steeper effective cents-per-kWh and a tighter disconnection clock.

The fee stack that turns an advertised rate into a real bill

Start-up cash is the first number most people notice. Under PUCT prepaid rules described in the agency's prepaid FAQ, a REP does not require a traditional deposit for prepaid; instead it requires ¹. ¹, so the check you write on day one can exceed $75 even though the prepaid connection balance itself is described as up to $75. Details sit on the ¹ for the specific product.

Ongoing costs are where advertised cents-per-kWh get slippery. Each REP sets its own fee menu. The PUCT tells shoppers to ¹ for product fees and charges. In practice, that can include daily service charges, payment processing fees at certain channels, fees for paper copies of usage summaries, and other non-energy charges that never appear in a headline energy rate. as recurring pain points for households living close to the edge.

Delivery charges sit underneath. Oncor's delivery charges to REPs , and REPs include those charges in customer pricing. Because fixed delivery and any fixed REP fees spread across fewer kWh for light users, a small apartment can see a much higher average price per kWh than a large house on the same plan, even when the "energy rate" looks identical. : headline rates are often built around a specific usage level, and base charges or minimum-usage fees can rewrite the math when your home uses less.

Variable pricing adds another twist. The PUCT notes that ¹: your prepayment buys a dollar amount of electricity, not a locked pile of kWh, and ¹—sometimes daily—so there is not one fixed price that applies to every unit you use. ²: the rate can move with the market and at the company's discretion, which can help when wholesale prices fall and hurt when they spike.

Wholesale conditions matter for that risk. EIA has forecast in a Short-Term Energy Outlook analysis—among the lower regional averages in that outlook—while still projecting . Variable prepaid customers feel wholesale and retail product changes faster than someone locked into a multi-year fixed plan.

How to read the Electricity Facts Label like a cost engineer

Texas requires an ¹ so customers can compare offers. The PUCT and shopping materials treat the EFL as standardized pricing disclosure; ¹ on Power to Choose and on the REP's site. , along with energy charges, base charges, and early termination fees for plans that have them.

What you are hunting on the EFL is not the teaser energy-only number in an ad. You want the average price per kWh at usage levels that match your home, and the fee table that explains what is baked into those averages. ¹⁰: ask what you will pay per kWh at 1,000 kWh average monthly usage, and ask whether that rate includes energy, transmission and distribution charges, and recurring customer charges.

A practical true-cost worksheet looks like this:

  1. Pull 12 months of usage if you can (or estimate summer and winter peaks separately). ¹¹, with higher consumption in months like August and February.
  2. Open the EFL for every prepaid and postpaid finalist and record the average price at the nearest usage tier to your typical month—and at your summer peak month.
  3. Add one-time or episodic costs the average price may exclude: connection balance, third-party payment fees, reconnection after a shutoff, and any paper-statement fees listed on the PDS or Terms of Service.
  4. Convert deposits on a competing postpaid plan into a cash-flow cost. Postpaid deposits are refundable if you leave in good standing, but they still tie up money. ² and ².
  5. Compare the all-in dollars for a normal month and a high-usage month, not just cents per kWh on a calm spring bill.

¹² can speed the side-by-side view, but treat the EFL as the controlling document, not the sorting column on a results page. when bill credits, tiers, or base charges are in play.

Disconnection, reconnection, and the cash buffer you actually need

Prepaid's sharpest cost is not always the rate. It is interruption risk.

The PUCT prepaid FAQ is blunt: ¹; if your balance falls below the disconnection balance, ¹. ¹. You should receive ¹—but if usage burns the balance faster than expected, ¹.

That is a different rhythm than traditional postpaid collections. that prepaid customers can face automatic shutoffs once balances hit zero, with far less runway than the longer notice periods associated with traditional nonpayment processes, plus fee stacking for payments, statements, or reconnects. The same reporting noted that who were not "indebted" in the same sense. The PUCT itself warns that ¹, and urges you to confirm eligibility before signing up.

If you are disconnected, restarting is a two-step cash event when the account is negative: ¹. The FAQ says you should ¹, with product-specific reconnection details on the PDS. Every avoidable reconnect is a true-cost item that never shows up in a shopping-site average price.

Deferred payment plans still exist in limited cases on prepaid—¹—including when an account reaches a ¹ (a National Weather Service heat advisory or cold alert), when a governor-declared disaster triggers PUCT requirements, or when the REP under-billed by $50 or more for reasons other than theft. Entering a deferred plan can ¹ until the plan is paid off. That protection can keep you powered; it can also lock you into a product you would rather leave.

Operationally, budget prepaid like a weekly fuel tank, not a monthly mortgage. Keep a buffer above the disconnection balance large enough to cover a hot weekend with the air conditioner running, a delayed paycheck, or a payment that takes hours to post through a third-party pay station. Autopay or calendar reminders are not optional extras; they are part of the product's cost of ownership.

Who prepaid fits—and who should walk away

Power to Choose frames prepaid as ², often without a long-term contract, but with a requirement to prepay on time, no monthly bill, electronic monitoring, and ². The PUCT's "is it right for you" checklist asks whether you ¹—and whether you can accept disconnection if the balance slips.

Prepaid tends to fit people who:

  • Need service without a large refundable deposit or a credit screen.
  • Want short or no contract terms and the ability to leave without an early termination fight.
  • Check their phone, will act on low-balance alerts, and can reload quickly.
  • Use prepaid's visibility to cut waste—, and households that respond to daily cost signals can stretch a balance further.

Prepaid is a poor fit when:

  • Someone in the home depends on electricity for critical or chronic medical needs (¹).
  • You expect energy assistance programs to cover shortfalls—¹.
  • Your household cannot reliably keep a positive balance through summer peaks.
  • You want a locked-in fixed rate for budgeting across a one- or two-year lease. ² aside from certain TDU, ERCOT administrative, or government-imposed fee changes—something most prepaid variable products do not promise.

Small businesses in competitive areas face the same math with less forgiveness: a mid-day outage from an empty prepaid balance can cost more in lost sales than any rate premium on a postpaid commercial plan. If cash is lumpy, a postpaid plan with a deposit or average billing may be cheaper in expected-value terms even when the EFL cents look higher.

Outside Texas, "prepaid" may mean something different—utility-run prepay meters in regulated territories, or competitive offers in other choice states. Always read local rules. The Texas documents cited here (PDS, EFL, PUCT prepaid FAQ) are Texas-specific; Ohio or Maryland shoppers should use their own official shopping sites and regulator FAQs rather than importing Texas disconnection timelines wholesale.

A shopping workflow that surfaces true cost

Use a deliberate sequence rather than sorting Power to Choose by the first price column you see.

  1. Confirm you are in a competitive choice area and identify your TDSP. ¹¹ and note which wires company serves the address; delivery charge levels differ by territory.
  2. Filter for prepaid only after you know your monthly kWh. ¹¹—use it after you estimate usage from past bills.
  3. Open the Fact Sheet / EFL and the PDS for every finalist. ¹¹ before you assume a plan fits.
  4. Ask the ¹⁰ out loud: all-in price at 1,000 kWh, whether TDU and recurring fees are included, fixed vs variable vs indexed, contract length, deposit (or connection balance), payment options, and what happens if you miss a payment.
  5. Price a reconnect and a third-party payment fee into your annual estimate even if you hope never to need them. Hope is not a line item; history is.
  6. Run the same EFL exercise on one or two strong postpaid fixed plans. Include the deposit's cash opportunity cost and any early termination fee if you might move. Only then decide whether prepaid's flexibility is worth the ².
  7. If you enroll prepaid, set notification channels the day you start, store the REP's payment options, and keep a written note of the disconnection balance and connection balance from the PDS.

For usage reduction—the one lever that cuts both prepaid burn rate and postpaid bills—¹³ still points to basics that move the needle: seal air leaks and weatherize, manage thermostat setbacks, and attack always-on loads. ¹³. On prepaid, every kWh you do not use is cash that stays in the account another day.

Bottom line: compare dollars, not slogans

Pay-as-you-go electricity in Texas is a legitimate product with clear rules: ¹, electronic notices, EFL and PDS disclosure, and a disconnection clock measured in days rather than long postpaid collections cycles. It can be the right tool when credit barriers or deposits would otherwise keep the lights off, or when you want daily visibility into spending.

It is the wrong tool when you treat the shopping-site energy rate as the whole cost. True cost is the EFL average at your real usage, plus TDU delivery reality, plus fee drag, plus the expected value of reconnects and missed assistance, minus any deposit you avoid. Run that math for a mild month and an August month. If prepaid still wins on total dollars and you can live with the shutoff rules, take it. If it only wins on "no deposit" marketing while losing on annual spend, take the postpaid plan, fund the deposit, and sleep through the night without watching a balance countdown.
