Cheap Light Companies in Texas (2026 Guide)

Picture two neighbors in Plano paying for the same kilowatt-hours delivered over the same Oncor wires. One locked in a plan two years ago and forgot about it. The other spent twenty minutes on Power to Choose last spring. Their monthly bills look nothing alike.

That gap exists because Texas deregulated its retail electricity market, which means residents in most of the state pick their own electricity provider, called a Retail Electric Provider (REP). The REP sets the energy rate and the contract terms. The poles-and-wires company, the Transmission and Distribution Utility (TDU), delivers the electricity and collects a pass-through delivery fee that appears on every plan regardless of which REP you choose.

The four TDUs serving deregulated Texas are Oncor (Dallas-Fort Worth and West Texas), CenterPoint Energy (Houston), AEP Texas (Corpus Christi, Laredo, and surrounding areas), and TNMP (parts of West and South Texas). Your TDU is determined by your address and never changes when you switch providers. Shopping for a cheap light company is really shopping for the best REP rate layered on top of your fixed TDU fees.

The Public Utility Commission of Texas (PUCT) oversees the market, licenses REPs, and runs powertochoose.org, the official state shopping site. Every REP is required to publish an Electricity Facts Label (EFL) for each plan, a standardized disclosure that shows the all-in rate at three usage tiers: 500 kWh, 1,000 kWh, and 2,000 kWh per month.

Cheap light company is how most Texans search when they want to lower their electric bill. The phrase covers REPs offering low per-kWh rates, low or no monthly base charges, and straightforward contract terms. The distinction matters because a REP advertising 7.9 cents/kWh might bury a $9.95 monthly customer charge that raises the effective rate considerably at low usage levels.

As of August 2026, the lowest advertised all-in rate in the Oncor/Dallas area at 1,000 kWh sits at roughly 6.8 cents/kWh across about 128 active plans. The median all-in rate across those same plans is around 15.9 cents/kWh. That spread, more than nine cents per kilowatt-hour, translates to a meaningful dollar difference on a typical Texas home using 1,000 to 1,500 kWh a month.

Rates differ by TDU territory and by usage level. A plan cheap at 2,000 kWh per month can be expensive at 500 kWh because of how base charges and bill credits stack up at different tiers. The EFL is the only document that shows you the real all-in number at each tier. For live rates updated daily, check ElectricRates.org's Texas page or run a search on powertochoose.org.

Start on powertochoose.org. Enter your zip code, and the site returns every licensed REP plan available in your area. Sort by price at your typical monthly usage (500, 1,000, or 2,000 kWh). The site displays the all-in rate from each plan's EFL, so you are already looking at numbers that include delivery charges.

A few practices separate informed shoppers from people who just grab the top result:

Match the usage tier to your reality. Pull up your last twelve months of bills or log into your TDU's smart-meter portal. If you average 800 kWh a month, sort by the 500 kWh column and cross-check the 1,000 kWh column. Some plans have bill credits that only trigger above a usage threshold, making them look attractive at 1,000 kWh but more expensive at lower usage.

Read the EFL before you enroll. Every plan has one. It lists the all-in price at all three tiers, the contract length, early termination fees, and any special conditions. Fifteen minutes with the EFL can prevent bill shock.

Check the contract term. Month-to-month plans offer flexibility but sometimes higher rates. Fixed-rate plans lock your energy charge for 6, 12, or 24 months. Neither is universally better; it depends on your situation and rate direction.

Look at the REP's customer service record. The PUCT publishes complaint data by provider. A plan that is two cents cheaper per kWh from a provider with a poor service history may cost more in time and frustration.

The EFL is a one-page standardized document every Texas REP must provide before you sign up. Think of it as a nutrition label for electricity plans. Here is what each section tells you:

Average Price per kWh at 500/1,000/2,000 kWh. This is the all-in number including your TDU delivery charge, any monthly base fee, and all taxes and fees averaged into a single cents-per-kWh figure at each usage level. This is the number to compare across plans.

Energy Charge. The per-kWh rate the REP charges for the electricity itself, before delivery.

TDU Delivery Charge. The pass-through fee from your wires company. It appears on every plan because it is set by the TDU, not the REP. You pay it no matter which light company you choose.

Monthly Customer Charge. A flat fee some REPs charge regardless of usage. A high customer charge pushes up your effective rate at low usage levels.

Bill Credits. Some plans credit your bill when usage hits a threshold (say, 1,000 kWh in a billing cycle). These credits are why a plan can look dramatically cheap at exactly 1,000 kWh but expensive at 900 or 1,100 kWh.

Contract Term and Early Termination Fee. Know how long you are locked in and what it costs to leave early.

If two plans list different all-in rates at 1,000 kWh, the EFL is the tiebreaker. Ignore teaser rates in advertising and go straight to the EFL.

Every electricity bill in Texas includes a TDU delivery charge, and those charges vary by utility. Oncor's delivery fees differ from CenterPoint's, which differ from AEP Texas's and TNMP's. Because those pass-through fees are baked into the all-in EFL rate, a plan that is the cheapest option in Houston (CenterPoint territory) might not be the cheapest option in Dallas (Oncor territory) even if the REP's energy charge is identical.

This means you should always compare plans using your actual zip code, not statewide averages. The rate figures cited in this post, roughly 6.8 cents/kWh at the low end and 15.9 cents/kWh at the median, reflect the Oncor/Dallas area at 1,000 kWh as of August 2026. Rates in your territory may be higher or lower. For current figures specific to your address, use ElectricRates.org or powertochoose.org.

Affordable light companies in Texas generally compete across a few plan structures:

Fixed-Rate Plans. The energy charge is locked for the contract term, typically 12 or 24 months. Your TDU delivery charge can still change (TDUs file rate adjustments with the PUCT), but your REP energy charge stays constant. Fixed-rate plans are popular because they provide predictability through summer peaks.

Variable-Rate Plans. The energy charge floats month to month based on market conditions. They sometimes start lower than fixed plans but can spike during high-demand periods, including Texas summers. Month-to-month variable plans let you switch anytime without an early termination fee.

Indexed Plans. The rate is tied to a market index, often the ERCOT wholesale price. These can be very cheap in mild months and significantly more expensive during heat events. They suit customers who track the market or have flexible usage.

Prepaid Plans. You pay before you use electricity, with no credit check and no deposit. Prepaid plans often carry a slight premium over the cheapest postpaid fixed rates but can be the right fit for renters or people building credit history.

Green or Renewable Plans. Some REPs offer 100 percent renewable content (wind, solar, or RECs) at rates that are sometimes competitive with standard plans. Worth checking if environmental sourcing matters to you.

For most households wanting the lowest possible rate on a 12-month term, fixed-rate plans tend to produce the cheapest all-in cost. Always verify with the EFL.

Switching REPs in Texas is designed to be straightforward. There is no physical work involved; the same TDU wires deliver power before and after your switch.

Step 1: Know your current contract status. Log in to your current REP's account portal or call them to find your contract end date and early termination fee. If you are month-to-month, you can switch anytime. If you are under contract, calculate whether the savings justify any exit fee.

Step 2: Shop with your usage in mind. Gather your last few bills or check your TDU's smart-meter portal for monthly kWh totals. Use that number to compare EFL rates on powertochoose.org or ElectricRates.org.

Step 3: Enroll online. Most REPs let you sign up in minutes on their website. You will need your address, service account number (optional but helpful), and a start date. The new REP coordinates the switch with your TDU.

Step 4: Watch for confirmation. You will receive an enrollment confirmation and a copy of your Terms of Service and EFL. Save these. Your switch typically takes effect on your next meter read date.

Texas law gives you the right to cancel a new enrollment within three federal business days of receiving your terms of service, without penalty. If something looks wrong in the confirmation documents, contact the REP immediately or file a complaint with the PUCT.

A few patterns show up repeatedly among customers who end up with higher bills than expected after switching to an 'affordable' light company:

Comparing headline rates instead of EFL rates. Advertising can feature the energy-only charge, not the all-in rate. Always pull the EFL for the real number.

Ignoring usage tiers. A plan with a large bill credit at exactly 1,000 kWh will look fantastic on a comparison site but can be expensive for a household averaging 700 kWh. Run the math at your actual usage.

Forgetting the early termination fee when switching mid-contract. A fee of $150 to $200 can wipe out months of savings from a cheaper plan. Time your switch to align with your contract end date when possible.

Choosing a variable plan during summer. Texas summers put extreme pressure on the ERCOT grid. Variable and indexed rates can rise sharply during heat events. Locking in a fixed rate before peak season is a common strategy among experienced Texas shoppers.

Not re-shopping at renewal. REPs often roll expiring customers into higher variable rates by default. Put a reminder on your calendar about 45 days before your contract ends so you have time to compare and switch without a gap.

Three resources cover the Texas market well:

powertochoose.org is the PUCT's official state shopping site. It lists every licensed REP plan with EFL-sourced all-in rates by zip code and usage tier. It is free, unbiased, and comprehensive.

ElectricRates.org's Texas page aggregates current plan data and updates rates regularly, making it useful for a quick side-by-side view before going deeper on specific providers.

The PUCT's Industry Scorecard on powertochoose.org lets you check a provider's complaint standing before you commit. A cheap rate from a company with a high complaint ratio is worth a second look.

As of August 2026, the spread between the cheapest and median all-in rates in the Oncor area runs roughly nine cents per kilowatt-hour. For a household using 1,200 kWh a month, that gap adds up fast. Spending half an hour comparing plans is one of the better uses of time for any Texas household that has not re-shopped in the past year.
