Constellation Review and Ratings

Last updated:

Read our Constellation Review and Ratings. Constellation currently holds a Clear Energy Facts Score of 4.0 out of 5, ranking #6 out of 42. We evaluate plan quality, pricing transparency, and customer service.

Constellation is a national energy giant (a Fortune 200 company) serving the Texas market and currently stands as the nation's largest producer of carbon-free energy. 

Constellation: What we like

  1. BBB accreditation: Constellation is a BBB-accredited business with an A+ rating.
  2. Exceptional Google Reviews (2026): It is currently difficult to find negative feedback for this provider in 2026. Based solely on customer service reviews, it is performing as one of the top-rated companies for the year so far.
  3. Established and trusted provider: It is a well-established company and earned the 2025 Great Place To Work® certification. Constellation also states that it is one of the largest producers of carbon-free energy in the United States.
  4. Consistent pricing: Rates are generally consistent across shopping platforms, making it easier to find their best offers regardless of where you compare plans.
  5. ETF assistance: They offer assistance with early termination fees when switching from another provider, covering up to $150. Learn more here.
  6. HVAC protection add-on: Several plans can be bundled with HVAC protection. This perk can be useful for small to medium repairs, but customers should carefully review coverage limits and exclusions. As of December 2025, coverage is capped at $2,000 with a $0 deductible, and certain items such as refrigerant (freon) leaks are not covered. Overall, this is a valuable add-on when its limitations are clearly understood. Learn more here.
  7. Low cancellation fees: Their cancellation fees are lower than the industry average.
  8. Strong referral program: Constellation offers a referral program where both you and your friend can receive a $50 gift card after signup. Learn more here.
  9. Rewards program praised by customers: Several Google reviews highlight Constellation’s rewards program as a positive perk. It’s the company’s free, standard loyalty program and often includes monthly giveaways and prizes for users. Learn more here.

Constellation: What we don’t like

  1. HVAC program limitations: Some users have reported dissatisfaction with the HVAC protection program, which makes it important to carefully review the Terms of Service and set realistic expectations. Understanding coverage limits and exclusions is essential before enrolling.
  2. Call center payment fee: A $6.95 fee applies if a customer chooses to make a payment through a call center agent instead of using self-service payment options.
  3. Bill Credit Plan Strategy: Many of their most advertised rates are bill credit plans that require reaching specific usage thresholds (usually 1,000 or 2,000 kWh). While these plans can offer value for medium-to-large homes that consistently hit those targets, they are generally not a good fit for small apartments. Lower consumption in an apartment often results in missing the credit entirely, leading to a much higher effective rate.
  4. Higher-priced True Fixed plans: While True Fixed Rate plans are available, their pricing is generally higher than the current market average.
  5. Mobile App Frustrations: The Constellation Energy Hub app is currently rated low across app stores. The app is relatively new, and improvements are expected as future updates are released.

Transparency Review in Detail

5.0 /5.0

Transparency

Ranked #1 of 42 companies

Constellation obtains the highest transparency score because its rates and plans are largely consistent across all platforms, including its website, sponsored content on Google, and the Power to Choose marketplace. While minor differences between rates on Power to Choose and the company’s website can occasionally occur, these variations are typically less than 3%.

Customer Service Review in Detail

4.0 /5.0

PUCT complaint record

Ranked #7 of 42 companies

In this section we focus on the company’s customer service, using the official complaint data from the Public Utility Commission of Texas (PUCT).

1. PUCT scorecard rating. This score shows how this provider compares to other Texas electricity companies based on the number of customer complaints the PUCT receives about them.

2. What the PUCT scorecard means. The PUCT publishes a scorecard that rates Retail Electric Providers based on their complaint history. It compares a company's market share to its share of complaints filed with the state. Companies that resolve issues before customers feel the need to contact the PUCT receive higher ratings (5 Power Circles), while companies that frequently force customers to escalate issues receive lower ratings.

If a company does not have a PUCT rating (or we show “No rating”), it usually means there is not enough historical data for the PUCT to calculate a score. This typically happens when a company is new to the market or has a customer base too small to be statistically compared to larger providers.
