In our Texas electricity provider reviews, Constellation Energy earned a score of 4.3 out of 5. This score ranks Constellation slightly above the industry average of 4.2 out of 5. The company offers unique plans that cover your heating and air system. You can choose from a variety of term lengths, including month-to-month, nine, 12, 24 or 36-month contracts.
While Constellation offers appliance protection plans that may benefit some Texans, it offers very few straightforward, no-gimmick energy plans. However, the light company does offer competitive electricity rates, and you can secure a rate lower than the Texas average for most plans when you use at least 1,000 kilowatt-hours (kWh) per month. Though, you might have limited plan choices since they aren’t available in every Texan city.
Despite these limitations, Constellation offers well-rated customer service, making it a strong energy choice in the Lone Star State.
Pros and Cons
Pros:
- Unique appliance protection plans
- Perks for EV owners
- Solid customer service rating
Cons
- Many confusing rate structures
- Limited plan variety
- Hard to compare plans online
Constellation Energy Plans
Constellation Energy offers five main plan types, but your options vary based on location. While Constellation offers a wide range of plan types, it doesn’t offer any straightforward options with easy-to-understand rates.
Most of its plans feature a bill credit, which can lead to confusing and unpredictable energy bills. Review your past bills to understand your usage and make sure it aligns with the bill credit requirements before signing up for a plan with a usage-based discount.
For example, the 12-month Fixed Rate + Bill Credit +A/C Protect Plus plan offers a $35 credit when you use at least 1,000 kWh and up to 1,999 kWh. With the same plan, you earn an additional $15 credit when your usage equals or exceeds 2,000 kWh. In short, your total discount — or if you get a discount at all — will depend entirely on your energy usage.
A/C Protect Plus plans cover breakdowns and monitor your heating and air system’s performance. This offering is unique to Constellation and might benefit those with aged systems or who need frequent repairs.
Electric vehicle (EV) plans offer time-of-use rates with free electricity or discounted prices during off-peak hours. You can choose from 12 or 24-month options and two different time-of-use cycles. For one of the EV plans, the on-peak time is from 6 a.m. to 10 p.m., so you get a discounted rate overnight. The other option provides free electricity from 12 a.m. to 4 a.m. Consider charging overnight and scheduling charge hours to get the most out of the discounted or free electricity times.
Constellation’s variable rate plan is the most expensive option. Its costs fluctuate month to month based on market conditions. We almost never recommend variable-rate energy plans because they often lead to unpredictable energy costs.

Our Thoughts on Constellation Energy
Constellation Energy earned a 4.3 out of 5 overall rating, landing above average in our rankings of 25 Texas energy providers. Constellation offers unique plan options that you won’t find with other providers, including those with A/C Protect Plus and for EV owners. You could receive additional savings if you frequently need HVAC repairs or own an EV.
However, it’s noteworthy that Constellation doesn’t offer any straightforward, no-gimmick energy plans. Energy companies offering straightforward plans without bill credits or complicated pricing structures tend to rank higher in our review. Based on our research, bill credits may advertise low prices but often lead to unpredictable energy costs.
Additionally, Constellation’s prices and plans are confusing compared to those of other providers with simpler website experiences. When comparing Constellation plans, take time to review the fine print. Some of the options appear similar, but the benefits may vary for different usage levels.
Constellation stands out for its wide range of plan offerings and its reputable customer service. However, we’d like to see the provider offer more straightforward plan offerings. While Constellation Energy has some attractive features, we suggest comparing plans and understanding the price structure before signing up to ensure it matches your needs.

What Customers Say About Constellation Energy
With Constellation’s 4.5 out of 5 rating for customer satisfaction, it’s not surprising that the provider has high ratings on Google Reviews as well. Constellation has a 4.6 out of 5-star rating based on more than 3,000 customer reviews. Customers like the addition of appliance repair and monitoring and comment on the affordable pricing.
“I have enjoyed Constellation Energy for seven years now. They are low priced, making it much more affordable to run the appliances and a/c as much as needed. They have an excellent bonus program designed to keep your AC tuned as well as other items throughout the house,” wrote Ashley B.
Those who used the appliance repair services reported positive experiences. “The tech that visited my home was such a hard worker. He made recommendations and made sure I understood what needed to be done. I am very impressed and satisfied with the service I received,” said Gail M.
Some negative reviews highlight confusion about bill credit plans. “I switched to this company because they promised to give $50 credit for each bill. They sent me the first bill without credit when I called customer service. They said we can’t do anything for you,” wrote Dale D. A customer service representative responded to this message explaining how energy usage impacts bill credit eligibility.
Despite the 1 out of 5 star average from 45 BBB reviews, Constellation has an A+ rating and BBB accreditation. Low BBB ratings are pretty standard across energy companies in Texas, so it’s not a major concern. Also, take note that BBB reviews aren’t just from Texas residents because Constellation operates in other deregulated states.
Reading Constellation Energy’s Electricity Facts Label
You will find the cost breakdown in your plan’s EFL, including the energy charge, utility fees and renewable percentage. Here’s an example EFL for the Fixed Rate Green plan in the TDU Oncor.
- Average price per kWh: These estimates show the average charges based on your energy use. The prices typically include bill credits, TDU fees and your energy charge.
- Base charge: Some providers or plans require a base charge or minimum usage fee. This charge varies by plan and provider but typically doesn’t cost more than about $10.
- Energy charge: This charge is what you pay per kilowatt-hour without considering discounts or bill credits. To understand potential total costs, it’s best to compare energy charges instead of average prices.
- TDU delivery charges: Your TDU charges a fee for delivering electricity. Delivery fees usually have a flat monthly charge and a fee based on usage.
- Type of product: This section indicates whether your plan has fixed rates or variable rates. Fixed rates remain constant throughout the contract term, but variable rates change based on the market.
- Contract term: This section details how long your contract lasts. Most energy providers offer 12, 24 and 36-month contract terms. In addition, Constellation has 18 and 20-month plan options.
- Early termination fee (ETF): Canceling a fixed-rate contract before its end date may result in an ETF. Constellation typically charges a $150 cancellation fee for fixed-rate plans.
- Renewable content: This section shows the percentage of your energy plan that comes from green energy. The average renewable percentage in Texas is 33%.
- Other disclosures: The disclosure section details if, why and how much your rate may change throughout your agreement.
Note the difference in rate across the three usage levels. While many bill credit plans have a very large rate range, this plan features a fairly reasonable range in rates because the usage credits are fairly small: $35 and $15, respectively. Also, note that the two usage credits apply at two different usage levels. We captured this EFL on January 14, 2025.
What Is the Best Way To Contact Constellation Energy?
Constellation Energy offers several contact options, including by phone, online chat, email and social media.
- Phone: Call 888-900-7052
- E-mail: Submit your message online
- Social media: Message on Facebook or X
- Home service contact: Schedule HVAC repairs or maintenance
If your home loses power, contact your utility company. As a retail electricity provider (REP), Constellation provides energy plans and manages billing while your TDU handles downed lines and outages.
How Do You Move or Transfer Service with Constellation Energy?
You can transfer your service to your new address if it’s within the provider’s service area. Simply call Constellation’s customer service and let them know you’re moving. After providing a move-in date and updated address, Constellation will handle the transition.
When you request to move service, Constellation typically processes it the same day. However, the provider recommends initiating a move about 30 days in advance to ensure you have power when you need it.
Final take: Constellation Energy Offers Reasonable Rates on Bill Credit Plans
Constellation Energy has a reliable business history and offers a range of unique electricity plans in Texas. Its plan variety means you can switch plans as your energy needs change while staying with the same trusted provider. We like the energy plans available for those who own an EV or need extra appliance protection, as they are not common offerings with other providers.
However, the bill credit plans on the provider’s website can be confusing and challenging to compare. As with any energy plan, thoroughly review the contract details and EFLs to avoid unexpected charges and find a plan that fits your energy needs. Additionally, if you’re looking for a more straightforward plan type, you may need to consider other providers, such as TriEagle Energy.
Frequently Asked Questions About Constellation Energy
Will Constellation Energy charge me a cancellation fee?
Constellation usually charges a $150 ETF when you cancel a fixed-rate plan before the contract ends — even with a longer term of 24 or 36 months. This is fairly rare among providers. Many charge significantly higher cancellation fees for long-term contracts. Regardless, you can avoid an ETF if you’re moving outside Constellation’s service area or you have less than two weeks in your contract. Variable rate plans don’t have a cancellation fee because they are month-to-month plans without a long-term contract.
Do the Constellation Energy rates shown include everything?
The average price per kilowatt-hour listed on your EFL is an estimate depending on the energy charge, TDU fees and potential base charge. These estimates assume you qualify for bill credits, making the total potentially misleading. We suggest comparing your typical usage to the average levels to determine how your rate may vary.
Does Constellation Energy run a credit check?
Yes, Constellation runs a soft credit check during the enrollment process. It won’t impact your score, but low credit or a history of late payments might result in paying a deposit to enroll in your plan. You can avoid deposit payments by requesting a letter of credit from your previous provider that shows your consistent payment history.
What is the best Constellation Energy electricity plan?
We recommend the Fixed Rate Green 12-month plan for competitively-priced renewable energy. However, the best Constellation electricity plan for you depends on your usage and what’s available in your area. Compare contract terms and energy charges to find the best plan for your needs.
