Choosing an energy plan in Duncanville with the best electricity rates can be challenging because the deregulated energy market has led to hundreds of plans and dozens of companies to choose from. According to the Public Utility Commission of Texas (PUCT), there are over 170 plan options from many electricity providers in the Duncanville area. While you can find many plans with fixed rates and clear contract terms, many plans advertise cheap electricity through deceptive marketing and hidden fees.

How To Choose The Best Duncanville Electricity Plan

Texas electricity providers offer a wide range of energy plans for Duncanville homeowners. Some plans offer straightforward fixed rates, but others use features like bill credits or time-of-use rates, which can make your power bills unpredictable. We recommend fixed-rate plans with 12-month contracts, which offer predictable monthly electricity bills while giving you the opportunity to find another rate once per year. Before enrolling in any plan, read its electricity facts label (EFL) to rule out any hidden fees, bill credits or tiered rates.

The best time to enroll in a fixed-rate plan is during spring or fall when Texas electricity rates are typically lower. You should avoid locking in your rate during summer or winter because energy prices tend to increase due to the high demand caused by air conditioners and space heaters. A 12-month contract term gives you the opportunity to secure low rates every year, but 24 and 36-month plans are also available, sometimes with lower rates than 12-month plans.

Before comparing Duncanville electricity plans, knowing your monthly energy usage is also critical. Most plans charge different rates at 500 kWh, 1,000 kWh and 2,000 kWh — one plan might be favorable for a large home using 2,000 kWh, but not for a small apartment using 500 kWh. If you don’t have a record of your latest power bills, you can download your usage data from the Smart Meter Texas website.

Duncanville Plan Types

Providers in Duncanville offer over 170 electricity plans across six main categories. For predictable energy costs, fixed-rate plans with 12+ month contracts are recommended, though other types may suit different consumption and payment preferences.

• Fixed-Rate Electricity Plans charge the same kilowatt-hour price throughout the entire contract term, typically 12-36 months. These plans offer price stability but include early termination fees if cancelled before the contract ends.
• Variable-rate electricity plans are month-to-month plans with no minimum contract term, but rates change monthly based on market conditions or provider decisions. These plans can lead to unpredictable bills and especially high rates during summer peak demand.
• Bill credit plans charge higher base electricity rates but offer bill credits if consumption falls within specified ranges. While they can provide savings when usage stays within the target range, rates can double if consumption falls outside it.
• Time-of-use energy plans charge different rates depending on the time of day, with highest rates during peak-demand periods and lowest rates during off-peak hours. These plans often include complex rate structures that make bills hard to predict.
• Solar buyback plans are designed for homes with solar panels, allowing customers to sell excess energy back to the grid while paying normal rates for grid electricity usage. These plans typically offer fixed rates with 12+ month terms.
• Prepaid energy plans allow customers pre-load their account with funds that are withdrawn as electricity is used in lieu of monthly bills. These plans typically don’t require credit checks or security deposits. Companies like Payless Power are known to offer prepaid electricity in Texas.

Duncanville’s Utility Company

You can choose your electricity provider in Texas, but your geographic location determines the transmission and distribution utility (TDU) that operates the local grid. Local utility companies are also sometimes referred to as TDSPs. Oncor Electric Delivery is the TDU that serves the Dallas-Fort Worth metroplex — including Duncanville. TDUs are also known as “poles and wires” companies because they deliver electricity from all providers in their electricity service area.

When you compare electricity plans in Duncanville, their advertised rates normally include Oncor’s fees. However, we recommend checking the electricity facts label (EFL) before enrolling in any plan to verify that the advertised rate matches the actual rate you will pay.

Also, note that your local utility company manages the local grid and repairs power outages. During an outage, you should contact your local utility company to report the issue or gather information about the problem.

Duncanville Commercial Electricity

The Texas deregulated electricity market allows both homes and businesses to choose their electricity providers. However, commercial rates are typically lower than residential electricity rates: business rates in Duncanville range from around 7 to 13 cents per kWh, depending on the specific plan chosen and your consumption level. Commercial rates can also vary significantly depending on the starting date of your plan. Many electricity providers serve both residential and commercial customers, including Reliant and TXU.
