Q: What steps do I need to take to choose a new supplier?

A: The process is easy:

  • Have a recent copy of your utility bill.
  • Review our pricing plans.
  • Carefully read the terms and conditions for your plan.
  • Choose the plan that best fits your needs and fill out the simple online form.

Q: Is my personal information safe?

A: Yes, we are required by law to keep your information confidential.

Q: If I choose Constellation, will it impact my participation in state assistance programs that help me with my energy bill?

A: If you currently participate in state assistance programs that help you with your energy bill, please check with your current program to see about eligibility for choice.

Q: If I select a contract, is there a fee for cancellation?

A: An early termination fee may apply, depending on which type of plan you choose. For instance, if you opt for a month-to-month electricity plan, then no fee applies. But, if you select a fixed-term contract and cancel your agreement before your contract period ends, then a fee may apply. Be sure to read the contract documents that apply to the plan you’re considering, and ask our friendly Customer Care Team any questions you may have prior to signing up.

Q: Will you check my credit?

A: Yes, as a part of the enrollment process we do check your energy risk score. Although this check is done through a national credit agency, it is a "soft inquiry" that will be referenced on your report and is not revealed to creditors or lenders; consequently, it will not negatively impact your credit score.

Business customers: We perform a credit analysis, once you complete a credit application.

Q: Why do you need my Social Security Number (SSN)?

A: Residential Customers: We use your social security number as a unique reference to identify you during energy risk score analysis. Once you provide your social security number on our secure website or to a Customer Care Team member, we will only store the last 4 digits in your account information. This information is maintained for future identification purposes.

Q: Help! I have always paid my bills on time but your website says I need a deposit!

A: It is possible that some of the information provided during enrollment was typed incorrectly. First, try clicking the back button on your browser to check the details, especially your birthdate, social security number, and spelling of your full name. If everything is correct and our web site continues to ask you for a deposit, contact your previous retail electric provider and request a letter of credit. They should send you a letter by U.S. Mail that will show your payment history. You can also ask them to fax the letter of credit to us at 1-866-477-8576 to help expedite the process. We would be happy to accept this letter in place of a deposit.

Q: I am moving into my new home in less than 3 business days, why can’t I get power sooner?

A: When you request a new move in, we typically process that order and send it out for completion the same day (possibly the following business morning if your order was submitted late in the afternoon or after hours). However, in order to physically come out and read/connect your meter, we have to make an appointment with your local metering company (your TDU) and they require at least 3 business days’ notice to perform this task. Since the TDU that services you is decided by where in Texas your meter is located, this timeline does not shorten regardless of which provider you choose (some other providers add their processing time to this 3 day window so they may quote a longer turn-around time).

Q: I am moving and Constellation is not available at my new address. What are my options?

Billing Questions for Texas Customers

Q: What are the TDU charges on my bill?

A: TDU charges are those charges associated with the delivery of electricity to a customer over poles and wires from your Transmission and Distribution Utility (TDU). The TDU charges are outside of the control of Constellation, are approved by the PUCT, and are passed through directly to you without additional markup. TDU charges are assessed by each respective TDU to all customers in their service territory, regardless of who their retail electric provider is. Constellation, as the billing agent for the TDU, collects these charges from customers on behalf of the TDU and remits them back to the TDU. Such charges are clearly labeled as a separate line item on your bill so that you can clearly distinguish which charges are Constellation’s and which are the TDU’s.

Q: How is the due date of my bill determined?
A: Your utility company reads the meter at your address each month and sends a report to us with your usage. We then generate a bill immediately after receiving your usage report from your utility. Your due date is two weeks after your bill is issued.

Keep in mind your due date may vary slightly from month to month. For example, if your bill was due on the 15th last month, your bill may be due on a different day the next month.

Q: Can I change the due date of my bill?

A: Unfortunately you can't. Your bill due date is determined by the date your utility company reads your meter. We do not control when that happens.

Q: What is the energy charge?

A: Your energy charge is the amount that Constellation collects from you for electricity supplied and used. It is what you agreed to pay at a cost per kilowatt when you signed your contract. It is also the component of your electricity bill that Constellation controls.

Q: Where do I find my average price per kWh?

A: Your average price per kWh can be found on your electricity facts label (EFL) or on your invoice labeled “The average price you paid for electric service this month” under the Current Charges Detail section. The average price is where you can see the overall cost of your electricity consumption and what you can use to compare your rate to any other rate in the market.

Q: Does the average kWh price include my local utility’s charges for delivery?

A: Yes. Our average price is an estimated all-in price based on 2,000 kWh of energy usage per month, and includes:

  • Your energy charge
  • Estimated TDU charges
  • All other recurring charges (e.g. bill credits or minimum usage fees, depending on your plan type)

Q: What is an unbundled rate plan?

A: An unbundled rate plan means our energy charges are billed separately from your Transmission and Distribution Utility (TDU) charges.

General Questions

Q: What is the difference between my local utility company and Constellation?

A: Constellation is a supplier of electricity and natural gas. Your local utility company will be responsible for the delivery of electricity or natural gas to your home and will maintain all poles and wires.

Q: How will the relationship with my current utility change if I buy power from an alternate energy provider?

A: Your relationship with your utility will remain the same. The utility company is bound by law to provide equal service to all of its customers regardless of your provider of electricity or natural gas supply.

Q: Will my utility company need to be notified of the change to Constellation?

A: When you make the switch to Constellation, we will take care of contacting your current utility.  You will receive a notice from your utility confirming your selection of Constellation as your electricity or natural gas supplier.

Q: What do I do if my power goes out?

A: Contact your local utility and report the outage. Your local utility, or distribution company, is still responsible for maintaining the reliability of the transmission and distribution system, including the poles, wires and pipelines that deliver your electricity and natural gas supply to your facility.

Q: Whom should I contact if I have a question regarding the status of energy competition or licensed retail energy providers (REPs) in my market?

A: You should contact your local Public Utility Commission or Public Service Commission.

Energy Choice and Retail Competition Facts

Q: Where can I learn more about energy and energy-related topics?

A: Visit our Energy 101 section where you can get an overview about energy, how it’s produced, what determines electricity pricing, and some of the terms commonly used.

You can also visit the U.S. Energy Information Administration’s page, Energy Explained, a web site that provides even greater detail about the many forms of energy available, energy generation, how the markets operate, how much renewable energy the United States uses, and hundreds of other energy topics.

Q: There are so many acronyms and terms! What do they mean?

A: The electricity industry is full of abbreviations that describe terms that are often unfamiliar to the everyday person. To help, we have prepared a glossary of terms to provide a quick walk-through of the definitions.

Q: How does switching electricity plans or providers affect my electricity delivery service?

It should not be affected. Your service should be constant while you switch. Your local utility will still be responsible for delivering your power and responding to any service calls or emergencies. They take care of the poles and wires. Switching to Constellation is a choice, and you are not required to switch in order to continue receiving power.

Q: Should I choose a move-in or a switch?

A: If you are just moving into a new property and the power is due to be newly in your name at this address, you should select Move-In. If the power is currently in your name at this address, with another provider, your options are Self-Selected Switch or Standard Switch.

Should I choose a standard switch or a self-selected switch? Select "Standard Switch" if you are not on a contract or if your current contract is about to expire in the next 10 days. This type of switch will typically take 3 to 7 business days.

Select "Self-Selected Switch" if you are in a contract with your current provider and would like to schedule a specific business day after its expiration for your switch. Please note that a Self-Selected Switch date may not be scheduled for more than 30 calendar days in advance from date of enrollment request.

Q: What is Renewable Energy?

A: Renewable Energy, also known as green power, is energy generated by the sun, wind, earth, and water. These resources replenish themselves naturally. Renewable energy fuels include solar, landfill biomass, wind and geothermal.​

Q: Do you have green or renewable energy plans?

A: We offer a renewable national wind product available for customers in states where we offer competitive electricity.
