As of August 2026, plans we offer in the Oncor territory average 15.3¢ per kWh at 1,000 kWh of monthly use, and today’s lowest effective rate is 6.8¢. Advertised rates move with your usage, so price plans at your own numbers.

Oncor is Thornton’s transmission and delivery utility. It owns the wires and meters and restores outages. You choose your retail electricity provider; Oncor delivers no matter who you pick.

Yes — most Thornton addresses have smart meters, so orders placed by 5 p.m. on a business day can start the same day. Pick your start date at checkout, up to 90 days ahead.

Compare effective rates at YOUR usage, not advertised rates — fees and bill credits bend each plan differently. Check the contract length and cancellation fee, then confirm delivery charges are included. The tables on this page do all three, and checkout takes about ten minutes.

Yes. Texas law gives you a 14-day window before your contract end date to switch with NO early-termination fee. Find your end date on your bill, then shop it today — the expensive move is drifting onto a holdover rate.

It changes with your usage. The lowest effective rate we price in Thornton today is 6.8¢ per kWh at 1,000 kWh — but a plan that wins at 1,000 kWh can lose at 2,000. Enter your ZIP and usage to see which company is cheapest for your home.

How to Find the Best Energy Plan in Thornton

#1 rule: Know your usage!

Discovering how much energy you will consume month-to-month is the ideal way to shop for power in Thornton. Why should you care?

The rate you see power companies advertising is for an exact monthly usage (usually 2000 kWh).

Every plan has a different calculation for how your monthly bill is computed, and your monthly bill will vary depending on how much electricity you use each month.

Unless you match the exact advertised usage each month, you will pay a “price per kWh” different than the one you saw advertised when you ordered.

Fortunately, there’s a better way to pick your electricity provider.

Calculating your expected monthly bill based on anticipated monthly usage, then comparing rates by total monthly cost is the best way to shop for the lowest rate for you.

Better yet, if you have a year 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 determine the right electricity plan for your home.

Compare Power does all this math for you in an instant. What could take you 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 investigation, spreadsheets, and calculations across hundreds of offers and navigating you step-by-step to the energy plan that’s best for your household’s usage.

We clarify the details, disclosing the various charges, so you’ll know precisely where your money is going and what to anticipate on your monthly bill.

We then help you order your plan with your selected energy provider without leaving our service.

The takeaway here is you must know your expected or historical usage before picking the right electricity plan for your home.

If you don’t know your usage, estimate

Suppose you recently purchased a home or business or cannot obtain 12 months of usage history. In that case, you can always estimate your average monthly energy usage.

While not as optimal as having all the previous 12 months of usage, estimating your average usage is better than blindly choosing the first plan you see advertised by an energy company at a specific usage that isn’t what you’ll consume.

Use Compare Power to find the best energy plan for your specific usage.

Moving to Thornton: Setting up Electricity

If this is your first time setting up electricity service in Thornton, you need to get the previous 12 months of energy usage for your new home to get the best rate.

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, Compare Power will do the math instantly to help you find the best plan for your home’s usage pattern.

Note: You can estimate your monthly usage if you can’t obtain a usage history. 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 Compare Power, you will receive automated reminders when renewing your existing plan or possibly switching plans.

Switching Electricity Companies in Thornton

Switching is good. Market conditions are constantly changing, so shopping for a lower rate yearly when your contract expires is essential.

Your existing electricity provider will generally raise your electricity rate once your contract expires. If you do not act, you’ll be left on a month-to-month rate significantly more 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 contact your current provider to cancel (no “break-up call”)
  • No one comes to your home
  • There is no disruption in your electricity supply
  • It takes just minutes

When you switch, your new electricity provider will take care of everything for you, including canceling your service with your previous company.

There is no loss of power when you switch. Electricity in Thornton is all delivered by the Oncor Transmission and Distribution Utility.

The wires and poles that deliver electricity to your home do not change when you switch energy companies. Therefore the reliability of your service is not affected.

You can pick any date within 14 days of your contract expiration without an “early cancellation” fee. That’s Texas Law.

If you’re still under contract, find out how many months remain on your contract. You can set a future start date with most providers up to 6o days in advance.

The amount saved each month by switching to a different electricity company may outweigh the one-time fee to get out of your contract early.

If you’re ready to switch and want to find the best plan, remember that knowing your usage is the best way to find the cheapest rate.

You will want to gather your historical usage for the past 12 months to determine your household’s best plan with the lowest rate.

Thornton Electricity Rates FAQs

Did You Know?

HISTORICAL

Thornton was established in 1871 as a railroad town along the Houston and Texas Central Railway, serving as a crucial shipping point for cotton and agricultural products from the rich Blackland Prairie region. The town was named after railroad official John Thornton, and its strategic location made it a vital link between Houston and Dallas during the late 19th century railroad boom.

RECENT

In 2020, Thornton completed a major infrastructure improvement project that upgraded its water treatment facility and replaced aging water lines throughout the city. This $2.3 million project, funded through state grants and local bonds, ensures reliable water service for residents and has attracted new businesses to the area.

FAMOUS PEOPLE

Country music singer and songwriter Roger Miller, famous for hits like 'King of the Road' and 'Dang Me,' spent part of his childhood in Thornton during the 1930s. Miller later won 11 Grammy Awards and was inducted into the Country Music Hall of Fame, often crediting his small-town Texas upbringing for inspiring his storytelling style.

DID YOU KNOW

Thornton is home to one of the oldest continuously operating general stores in Texas, established in 1873 and still serving customers today. The store maintains its original wooden floors, tin ceiling, and vintage cash register, and locals claim it's where the first Coca-Cola was sold in Limestone County in 1886, though this remains a friendly dispute with neighboring towns.

CULTURAL

Every October, Thornton hosts the annual Cotton Festival, celebrating the town's agricultural heritage with a parade featuring antique tractors, cotton picking demonstrations, and the crowning of the Cotton Queen. The festival draws visitors from across East Texas and features traditional bluegrass music, homemade quilts, and a famous cornbread cook-off that has been running for over 40 years.
