Independent provider review

Constellation Review

Last reviewed

Constellation is one of the largest energy companies in the country and the parent of Champion Energy and GoodCharlie. Its Texas lineup is complex. It offers plain fixed-rate plans and A/C service bundles for homeowners who want HVAC coverage with their electricity, alongside several bill-credit plans, which we generally don't recommend. It has one of the better complaint records in the state, and its renewal offers are generally reasonable.

Editorial insight

Our Take

Constellation brings scale and stability. It is a national energy supplier with a long track record, it consistently ranks near the top of the Public Utility Commission of Texas complaint scorecard, and it recently acquired two of the providers we rate highest, Champion and GoodCharlie.

The Constellation brand itself is less straightforward than its sister companies. Half of the eight plans in our check depended on bill credits: its lowest advertised plan, both A/C Alert & Service bundles and a 24-month plan. On the EFLs we checked, the credits were $35 a month at 1,000 kWh and another $15 at 2,000 kWh. Simple fixed-rate plans are there, including a 12-month plan with no minimum usage fee and a 100% renewable plan, but you have to sort through the bill-credit plans to find them.

Our verdict

Constellation is a stable, well-run provider with a strong complaint record. Choose one of its simple fixed-rate plans, read the EFL on anything with credits or add-ons, and compare the market before you renew.

Provider evaluation

How We Graded Constellation

Every provider is graded on the same four criteria: Price Competitiveness, Pricing Transparency, Customer Experience, and Renewal Practices. Grades run A to D and reflect our independent editorial assessment, not just advertised rates.

  1. B-

    Price Competitiveness

    Constellation's simple fixed-rate plans are reasonably priced but rarely the lowest available. Compare its offers against the current rates in the table below.

  2. C+

    Pricing Transparency

    Half of Constellation's lineup depends on bill credits of up to $50 a month, including its lowest advertised plan, both A/C service bundles and a 24-month plan. We generally don't recommend bill-credit plans, because a month below the threshold costs noticeably more. Plain fixed-rate plans are available, including a 12-month plan with no minimum usage fee, so a careful shopper has clear choices.

  3. B+

    Customer Experience

    Constellation consistently ranks near the top of the Public Utility Commission of Texas complaint scorecard, one of the better records among large providers. Phone support is available weekdays and Saturdays, and live chat is available online.

  4. B

    Renewal Practices

    Constellation's renewal offers are generally reasonable. They can come in somewhat above its new-customer rates, but without the sharp jumps common at teaser-rate providers. It still makes sense to compare the market before you renew.

The overall grade of B is our editorial judgment across all four criteria, not a simple average. Read our editorial standards

Standout features

What Makes Constellation Different

Constellation's advantages come from its size and its service record, with a rewards program on top.

  1. 01

    A Large, Stable Company

    Constellation is one of the largest energy companies in the United States and the parent of Champion Energy and GoodCharlie. Few Texas providers have stronger financial backing.

  2. 02

    Strong Complaint Record

    Constellation consistently ranks near the top of the Public Utility Commission of Texas complaint scorecard, which adjusts complaints for the size of each provider.

  3. 03

    Home Service Bundles

    Some plans include A/C breakdown coverage and performance monitoring for up to two units, which can appeal to homeowners who want electricity and HVAC protection from one company.

  4. 04

    Renewable and Time-of-Use Options

    Fixed Rate Green is backed by 100% wind and solar renewable energy certificates, and Free Power Hours 12 includes free electricity from midnight to 4 a.m. EV owners can choose FreeCharge plans with the same free overnight window or FlexCharge plans with a lower rate from 10 p.m. to 6 a.m.

  5. 05

    Constellation Rewards

    Customers earn Reward Points every month and can redeem them for deals on dining, shopping, entertainment and travel. The program also runs gift card and product giveaways and a prize wheel that awards a $5 to $25 gift card on every spin. It's a nice extra, but it doesn't lower your electricity rate, so weigh the plan's price first.
