Quick answers

Sunnyvale electricity questions, answered

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 Sunnyvale’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 Sunnyvale 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 Sunnyvale 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 Sunnyvale

#1 rule: Know your usage!

Knowing how much energy you will consume in a month is the ideal way to find a deal on electricity in Sunnyvale. Why should you care?

The “price per kWh” you see energy companies advertising is for an exact monthly usage (usually 1000 kWh).

Every plan has a different equation for how your monthly statement is computed, and your monthly bill will be determined by how much electricity you use in a month.

Unless you match the advertised usage each month, you will pay a “price per kWh” different than what you observed when you signed up.

Fortunately, there’s a better way to choose your energy provider.

Calculating your expected monthly bill based on estimated monthly usage, then comparing plans by the total monthly bill is the best way to shop for the lowest rate for your household.

Better still, if you have a year of usage history for your home, 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 best way to find the perfect energy plan for your home.

Compare Power does all the complicated math for you instantly. What takes hours inside a spreadsheet is now done in just moments.

We put you in the driver’s seat, taking what would amount to hours of investigation, spreadsheets, and computations across hundreds of offers and assist you step-by-step with the energy plan that’s best for your household’s usage.

We clarify the fine print, disclosing all fees, so you’ll know precisely where your money is going and what to expect on your monthly bill.

We then assist you in ordering your plan with your selected electricity provider without leaving our service.

The bottom line is you must know your expected or historical usage before ordering 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 usage history. In that case, you can always estimate your average monthly energy usage.

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 Compare Power to shop for the best electricity plan for your specific usage.

Moving to Sunnyvale: Setting up Electricity

If this is your first time setting up electricity service in Sunnyvale, 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, Compare Power will do the math instantly to help you find the best plan for your home’s usage pattern.

Note: If you cannot obtain historical usage information, a second option would be to estimate your future usage via our “Help Me Choose” tool. The tool can assess your home’s projected electricity consumption by simply entering your zip code.

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 Sunnyvale

Switching is good. Market conditions are constantly in flux, so shopping for a lower price each year when your contract expires is essential.

Your existing energy company will typically raise your electricity rate once your term expires. If you do not act, you’ll be left on a month-to-month rate significantly higher than the plan you signed up for.

Before renewing your contract, check the rates of competing electricity providers.

Switching can save you hundreds or thousands of dollars yearly on your electricity 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.

Your lights stay on when you switch. Electricity in Sunnyvale 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 electricity companies. Therefore the reliability of your service is not affected.

You can choose any date within 14 days of your contract expiration without an “early cancellation” 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 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 know how to find the best plan, remember that understanding your usage is the best way to find the best rate.

Keep in mind that when you get ready to switch and you want to know the most efficient way to find the right plan at the best rate, it is essential that you first understand your usage. To accomplish that, you must collect the usage history for the past 12 months.

Sunnyvale Electricity Rates FAQs

Did You Know?

HISTORICAL

Sunnyvale was founded in 1953 as a planned community by developer Ray Hubbard, who envisioned a small suburban town with large lots and a rural feel just outside Dallas. The town was incorporated in 1953 with only 200 residents, making it one of the youngest incorporated cities in Dallas County, designed specifically as a bedroom community for Dallas workers seeking country living.

RECENT

In 2019, Sunnyvale completed a major downtown revitalization project that transformed the historic Town Square area into a modern community hub with new shops and restaurants. The city also implemented a comprehensive smart city initiative, installing LED streetlights and digital infrastructure throughout the community to improve energy efficiency and connectivity for residents.

FAMOUS PEOPLE

Country music star LeAnn Rimes lived in Sunnyvale during her teenage years when she first rose to fame in the 1990s. She recorded her breakthrough hit 'Blue' while residing in the community, and often mentioned how the small-town atmosphere of Sunnyvale helped keep her grounded during her rapid rise to stardom at age 13.

DID YOU KNOW

Sunnyvale has one of the most unusual city council meeting traditions in Texas - they begin each meeting by reading aloud thank-you letters from residents, a practice that started in 1965 and continues today. The city also holds the distinction of having the smallest incorporated area in Dallas County while maintaining its own independent school district, fire department, and municipal services.

CULTURAL

Sunnyvale is famous for its 'Town Days' festival held every October, which features the unique tradition of crowning both a 'Miss Sunnyvale' and a 'Mr. Sunnyvale' in separate competitions that have been running since 1958. The community takes enormous pride in maintaining its small-town character despite being surrounded by major Dallas suburbs, with many families having lived there for multiple generations and city policies specifically designed to preserve the rural atmosphere.
