Save on heating and cooling your Duncanville home with Rhythm.

The summer months are characterized by intense heat and low humidity, making temperatures feel even hotter. Winters are relatively mild, with cooler temperatures during the day and occasional cold spells at night. Spring and fall are generally pleasant, offering moderate temperatures and manageable weather conditions. Rainfall is fairly limited, with most of it occurring in the spring and summer. 

This is one major reason why many Duncanvilleians residents choose a fixed rate plan with a 12, 24, or 36 month contract: so they can know what to expect from each month’s energy bill. But our variable rate, time of use, and month-to-month plans are also built with Duncanvilleians in mind, to make sure that you find a plan that fits your needs and your budget.

FAQ

Because Duncanville, like large parts of Texas, has a deregulated energy market, your electricity will be generated and transmitted by a utility that is assigned based on your area, but you must choose a retail energy provider (REP). For a handy guide on how to choose which plan is right for you, read How to Shop for Energy in Texas.

For Duncanville residents, we offer fixed, variable, time-of-use, and month-to-month plans, all of which are powered by green energy.

Got an electric vehicle? We’ve got you covered, with EV Plans tailored just for you.

Many of our plans come in 12, 24, or 36 month term lengths. Some, like our month-to-month plan, do not require a long-term contract.

If thousands of happy customers are any indication, then you’re going to love Rhythm Energy. But just to make sure that you do, we offer a 30 day risk-free trial period. If you break your contract after the first 30 days, we will charge an early termination fee of $10-20 for each whole month remaining in your contract, depending on the plan selected.

The rate you pay depends on where you live, determined by how much it costs to produce electricity, delivery fees from your utility, and the energy market. We offer fixed rate plans that bill you the same monthly rate for 12, 24, or 36 months, as well as variable rate plans that change monthly based on the wholesale cost of energy.

Some of our plans do require a deposit, which can be paid online during plan sign-up or by calling 1-888-7RHYTHM. The deposit must be satisfied before an enrollment can be confirmed or electricity service started. Deposits will be fully reimbursed after 12 consecutive on-time payments, with interest at the rate approved by the Public Utility Commission of Texas. Based on their credit profile, some customers may qualify for the Deposit Alternative Program.

Rhythm Energy offers same-day electricity connection, enabling fast and easy services for our customers.

Texas electricity providers have no control over power outages, but at Rhythm Energy we are committed to helping make sure that the power you want and need is reliable. Because utility companies, rather than providers, are responsible for maintaining the grid, if you experience a power outage then you should contact your utility. Find the right phone number and helpful tips here.

You can also stay up to date on live grid and power outage information through updates from your local utility company, as well as through ERCOT alerts. Sign up here for ERCOT grid emergency alerts to be sent to your email address.

Diversifying the sources of power that Duncanvilleians use into more renewable energy sources is an important step in stabilizing the grid. An area that relies heavily on natural gas for power generation (like Duncanville) can be subject to gas shortages and volatile prices on the market. By diversifying into a greater number of renewable sources like Rhythm Energy uses, particularly in larger cities, the state may be able to help avoid future blackouts. To learn more about the grid and what measures are being taken to stabilize the grid, read our article on the Texas Power Grid.
