How to find the best energy plan in Duncanville
#1 rule: Know your usage!
Discovering how much electricity you will consume in a month is the ideal way to shop for power in Duncanville. Why does this matter?
The rate you see electricity companies advertising is for an exact monthly usage (usually 2000 kWh).
Every plan uses a different equation for how your monthly statement is computed, and your monthly bill will change according to how much electricity you use in a month.
Unless you use exactly the advertised amount each month, you will end up paying an effective “price per kWh” different than what you observed when you signed up.
Thankfully, there’s a better way to shop for a power plan.
Calculating your expected monthly bill based on expected monthly usage, then comparing plans by total monthly cost is the best way to shop for the best rate for you.
Even better, if you have 12 months of usage history for your household, you can compare plans by total annual cost. This annualized method considers the changes in usage between the summer and winter months and is the ideal way to discover the perfect electricity plan for your home.
ComparePower does all the complicated math for you in an instant. What takes hours on a spreadsheet is now done in a few seconds.
We put the power in your hands, taking what would amount to hours of research, spreadsheets, and computations across hundreds of plans and assisting you step-by-step with the energy rate plan that’s best for your home’s consumption.
We clarify the details, disclosing all charges, so you’ll know precisely where your money is going and what to anticipate on your bill.
We then help you sign up with your selected energy provider without leaving our website.
The bottom line is you must know your expected or historical usage before selecting the right electricity plan for your home.

If you don’t know your usage, estimate
If you cannot acquire 12 months of historical usage, or you’re the owner of a brand new home, the next best thing is to estimate how much energy you will use in an average month.
Although knowing the previous 12 months of usage is optimum, it is far better to estimate the average energy consumption than to select the first electricity provider that you see advertised. After all, you have no idea how much energy you will use at that point.
Use ComparePower to shop for the best energy plan for your specific usage.
Moving to Duncanville: Setting up electricity
If this is your first time setting up electricity service in Duncanville, to get the best rate, you need to get the previous 12 months of energy usage for your new home.
Ask the previous homeowner to provide you with their past 12 months of usage.
This information is readily found in recent billing statements.
Acquiring usage for the past 12 months may take effort, but the time (and savings) will be well worth it.
Once you have historical usage, ComparePower will do the math instantly to help you find the best plan for your home’s usage pattern.
Note: If you can’t obtain a usage history, you can estimate your monthly usage instead. Utilize our “Help Me Choose” tool when you enter your zip code below, and we’ll help you evaluate your home’s usage.
By signing up for a plan through ComparePower, you will receive automated reminders when renewing your existing plan or possibly switching plans.
Switching electricity companies in Duncanville
Switching is good. Market conditions are always changing, so it is important to shop for a lower price every year when your contract is about to expire.
Your existing electricity company will typically raise your electricity rate once your term expires. If you do not take action, you’ll be left on a month-to-month rate significantly higher than the plan you signed up for.

Before renewing your contract, shop the rates of competing electricity companies.
Switching can save you hundreds or thousands of dollars yearly on your energy bill.
Switching is easy:
- You don’t have to call your current company to cancel (no “break-up call”)
- No one comes to your home
- There is no disruption in your power supply
- It takes just minutes
When you decide to switch, your new energy provider will handle everything for you, including canceling service with your previous provider.
Your lights stay on when you switch. Electricity in Duncanville is all delivered by the Oncor Transmission and Distribution Utility.
The wires and poles that deliver power to your home do not change when you switch energy providers. Therefore the reliability of your service is not affected.
You can choose any date within 14 days of your contract expiration date without an “early termination” penalty. That’s Texas Law.
If you’re still under contract, check how many months remain on your contract. You can set a future start date with most companies up to 6o days in advance.
And even if you’re well inside your contract, savings achieved on your monthly bill by switching companies may outweigh the fee of breaking your existing contract.
If you’re ready to switch and want to know how to find the best plan, remember that understanding your usage is the best way to find the best price.
You will want to gather your historical usage for the last 12 months to determine your household’s best plan with the lowest rate.
