ComparePower: Texas Electricity Comparison Tool Review (2026)

ComparePower is a Texas electricity comparison marketplace that lets consumers compare plans from 50+ Retail Electric Providers in a single search. ComparePower aggregates plan data—rates, contract terms, fees, renewable content—and presents it in a standardized format so you can compare apples to apples.^[1]

ComparePower operates as a licensed exchange under PUCT rules. The platform earns a commission from REPs when customers enroll through the site. This commission is already factored into the plan rates—you do not pay extra for using ComparePower compared to going directly to a REP.

The platform launched in 2013 and has facilitated millions of electricity enrollments. ComparePower serves the entire ERCOT deregulated market: customers of Oncor, CenterPoint, AEP Texas, TNMP, and LP&L.

ElectricRates.org uses ComparePower's API to power our Texas electricity comparisons. When you compare Texas plans on our site, the data comes from ComparePower's real-time feed of available plans.

ComparePower's process is designed to get you from search to enrollment in under 5 minutes. Here is how the flow works.

Step 1: Enter your ZIP code. ComparePower identifies your TDU based on your location. This determines which plans and delivery charges apply to your address.

Step 2: Browse available plans. Plans are displayed with key details: rate per kWh at 500, 1,000, and 2,000 kWh; contract length; monthly fees; renewable percentage; and early termination fees. You can filter by plan type (fixed, variable, green) and sort by rate.

Step 3: Review the Electricity Facts Label (EFL). Every plan links to its official EFL—the standardized disclosure document required by the PUCT. The EFL shows the complete rate breakdown at three usage levels.

Step 4: Enroll online. Select a plan, enter your service information (address, ESID, move-in date or switch date), and complete enrollment. ComparePower submits your enrollment directly to the REP.

Step 5: Confirmation. You receive enrollment confirmation from both ComparePower and your new REP. The switch typically takes 1-3 business days.

Power to Choose is every Texas consumer's right to pick their electricity provider. The Public Utility Commission of Texas (PUCT) runs the official comparison website at powertochoose.org to help consumers exercise that right. ComparePower and the Power to Choose website serve the same basic function—comparing electricity plans—but differ in important ways.^[2]

Plan coverage: The Power to Choose website lists every plan from every PUCT-licensed REP. ComparePower lists plans from participating REPs (50+), which covers the vast majority but not all providers.

User experience: ComparePower invests heavily in interface design. Filtering, sorting, and plan comparison tools are more polished than powertochoose.org's simpler layout. ComparePower also offers usage-based recommendations.

Enrollment: Both allow online enrollment. ComparePower's enrollment is integrated directly into the comparison flow. The Power to Choose site links you to individual REP websites to complete enrollment.

Neutrality: powertochoose.org is a government-run site with no commercial interest. ComparePower earns commissions from REPs, though plan rates are the same as going direct. Read our full Power to Choose guide for deeper analysis.

ComparePower's filtering system helps narrow hundreds of plans to a manageable shortlist. Knowing which filters matter saves time.

Usage level filter: The most important filter. Plans are priced at 500, 1,000, and 2,000 kWh. A plan ranked #1 at 1,000 kWh might rank #20 at 2,000 kWh due to tiered pricing or usage credits. Set this to your actual monthly usage for accurate comparisons.

Contract length filter: Choose between month-to-month, 6-month, 12-month, 24-month, and 36-month terms. Longer terms generally offer lower rates. Month-to-month plans offer flexibility at a premium.

Plan type filter: Fixed rate (locked price), variable rate (changes monthly), indexed rate (tied to wholesale prices). For most households, fixed rate is the safest choice.

Renewable energy filter: Filter for 100% renewable, partial renewable, or conventional plans. Texas renewable plans are often price-competitive with conventional options.

Pro tip: After filtering, sort by the rate at your specific usage level and review the top 3-5 plans' EFLs before enrolling. The cheapest rate isn't always the best deal once fees are factored in.

Finding the lowest rate on ComparePower requires knowing a few market dynamics that aren't obvious from the search results.

Check rates at your actual usage. Do not default to 1,000 kWh if your home uses 1,800 kWh. Many plans have minimum usage fees or bill credits that make rates dramatically different at various usage levels. Check your Smart Meter Texas data for your actual average.

Shop during off-peak months. Spring (March-May) and fall (October-November) typically offer the lowest fixed rates. REPs price plans based on forward wholesale costs, and summer expectations drive up rates from June through September.

Compare total monthly cost, not just rate. A plan at 9.5 cents per kWh with a $9.99 monthly fee costs more than a plan at 10.2 cents with no fee—at usage below 1,400 kWh. The EFL at your usage level accounts for fees, but double-check.

Watch for promotional pricing. Some plans offer low introductory rates that increase after a few months. Read the EFL fine print for any "promotional" or "introductory" language.

Avoid variable rates in summer. Variable rates can spike 50-100% during Texas heat waves when wholesale prices surge on the ERCOT market.

Enrolling through ComparePower requires a few pieces of information. Having these ready makes the process take under 5 minutes.

Required information:

Service address: The physical address where you want electricity service. Must be an address in the ERCOT deregulated market.

ESID (Electric Service Identifier): Your meter's unique ID. ComparePower can usually look this up from your address. If not, find it on your current bill. See our ESID lookup guide.

Service date: For switches, your new plan starts within 1-3 business days. For move-ins, choose your desired start date at least 3-5 business days in advance.

Personal information: Name, date of birth, SSN or driver's license number (for credit check unless choosing prepaid or no-deposit plans), email, and phone number.

After enrollment: You receive confirmation emails from ComparePower and your new REP. Your existing provider (if switching) is notified automatically—you do not need to call them to cancel. Your TDU (Oncor, CenterPoint, etc.) processes the switch in the background.

ComparePower operates under PUCT regulation as a licensed electricity marketplace. Understanding how the business model works helps you use the platform with confidence.

How ComparePower makes money: REPs pay ComparePower a commission for each customer enrollment. This commission is built into the plan rate—the rate you see on ComparePower is identical to what you'd pay enrolling directly with the REP. You do not pay extra for using a comparison site.

PUCT oversight: The PUCT requires all plan information displayed on comparison sites to match the official Electricity Facts Label. Misleading rate displays can result in fines. ComparePower pulls plan data directly from PUCT-registered EFLs.

Unbiased sorting? Like any comparison marketplace, be aware that default sorting may factor in commission rates. Always sort by rate at your usage level rather than relying on default or "recommended" sorting to see the truly cheapest options.

Customer reviews: ComparePower has consistently strong ratings on Google and BBB. Complaints typically relate to REP service issues rather than the comparison platform itself. ComparePower provides customer support for enrollment-related issues.
