Constellation Energy main energy services

Constellation energy for residential customers

Constellation offers a variety of fixed-rate electricity plans and natural gas options that fit with most budgets. It also provides renewable energy plans at fixed rates that can be 100% wind, solar, or a combination of both.

Constellation Energy also provides various home services, such as a professional energy efficiency assessment, a smart home security system, or all-in-one energy and A/C bundle.

Constellation Energy for business customers

Small businesses and larger commercial or industrial customers have access to Constellation Energy electric rates as well. They can also choose from a varied list of natural gas or renewably sourced energy plans, working with Constellation to find the most energy-efficient plan.

Green energy options with Constellation Energy

Constellation Offsite Renewables (CORe) and Renewable Energy Certificates (RECs) are two ways businesses can take advantage of Constellation’s renewable programs. CORe offers businesses access to offsite renewable energy through retail power contracts, and RECs give businesses the ability to publicly claim they have procured renewable energy to help advertise their sustainability goals.

For residential customers, sourcing your energy from 100% wind power is an easy way to take advantage of Constellation Energy’s renewable energy profile.

The company also installs on-site solar panels at no upfront cost to the customer. Constellation does this by still owning and maintaining the system, while you purchase the energy that is produced by the solar PV. This can be done for either business or residential customers.

Other Constellation Energy initiatives

Constellation energy plans can come with tools to help your system safely adapt to the changing grid. Things such as cogeneration, backup generation, batteries, and fuel cells are becoming an ever-growing part of the energy industry.

Community investment

As previously mentioned, Constellation Energy has a vested interest in working with the communities it serves. One of its strongest allies is Habitat for Humanity, with whom they work with to provide affordable power to homes in need. It also gives through E2: Energy to Educate, providing grants for projects that teach students about energy. The company also has its Community Champions grant program, where customers can apply for smaller grants for passion projects.

Energy plan FAQs

What is a fixed-rate plan?

A fixed-rate plan means you pay the same electricity supply rates every month on your electric bill. The length of the bill can vary, from month-to-month, 12 months, 24 months, or even 30 months

What is a variable-rate plan?

A variable-rate plan means your electricity supply rates per month for electricity fluctuate with the wholesale price of the electricity.

Who do I call if there’s an outage?

Don’t call your electricity provider, but your local utility company regarding any power outage. It is responsible for delivering electricity to your home or business and maintaining the lines that get it there.

What happens if I move?

Contact your provider to see if it offers Texas electric plans to your new address. If it does, you can still continue service with your provider by updating information. If not, click here to learn more about switching providers. If you can demonstrate that you are moving, you normally won’t owe an early termination fee.

Why does Chooseenergy run a credit check?

We run what is called a soft credit check, which determines whether you need to pay a deposit for service and how large that deposit will be.

A few things to remember

  • Don’t forget to read your plan’s Electricity Facts Label before you sign up for service. This contains essential information such as:
    • Price per KW-hour
    • Early termination fees
    • What percentage of your power is renewably sourced
  • Whatever energy provider you choose will set up service with your utility company or your transmission and distribution service provider (TDSP). There shouldn’t be a break in your power supply during this transition.
  • The same TDSP that delivers your electricity will maintain your electric infrastructure. Utility fees are labeled as TDU or TDSP on your monthly bill and are separate from your provider charges.
