AboutPort Isabel
Did You Know?
Port Isabel was founded in 1928 and named after Queen Isabella of Spain, who sponsored Christopher Columbus's voyages to the New World. The town was established as a deep-water port to serve the Rio Grande Valley's growing agricultural industry, particularly citrus and cotton exports. During World War II, the port played a crucial role as a training base for naval personnel and a departure point for military supplies heading to the Pacific Theater.
In 2019, Port Isabel completed a major waterfront revitalization project that transformed the historic downtown area into a tourist destination featuring new restaurants, shops, and a marina expansion. The $15 million project included the restoration of several 1930s-era buildings and the creation of a new boardwalk that connects to South Padre Island. This development has significantly boosted the local economy and attracted new businesses to the area.
FAMOUS PEOPLE/EVENTS: Port Isabel is famous for being the filming location for several scenes in the 1956 movie 'Giant' starring Rock Hudson, Elizabeth Taylor, and James Dean. The iconic Port Isabel Lighthouse, built in 1852, served as a backdrop for the film and has since become one of the most photographed landmarks in South Texas. The lighthouse was also used as a navigation aid for ships carrying supplies during the Mexican-American War.
Port Isabel is home to the world's largest population of Kemp's ridley sea turtles, the most endangered sea turtle species on Earth. Every year between April and July, hundreds of these rare turtles come ashore to nest on the nearby beaches, with some females weighing up to 100 pounds. The town has become a major center for sea turtle research and conservation, with scientists from around the world coming to study these ancient mariners.
Port Isabel hosts the annual Texas International Fishing Tournament, which has been running since 1934 and is one of the oldest saltwater fishing competitions in the United States. The four-day event attracts thousands of anglers from across North America who compete for prizes in multiple categories including red snapper, king mackerel, and tarpon. The tournament has become so integral to the town's identity that local schools close during the event, and many businesses offer special tournament week promotions.

How to Find the Best Energy Plan in Port Isabel
#1 rule: Determine what your usage is!
Knowing the amount of energy you will consume monthly is the ideal way to shop for power in Port Isabel. Why is this so vital?
The rate you see energy companies advertising is for an exact monthly usage (typically 1000 kWh).
Every plan uses a different equation for how your monthly bill is computed, and your monthly bill will vary depending on how much power you consume 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 enrolled.
Thankfully, there's a better way to choose your power provider.
Calculating your total monthly bill based on anticipated monthly usage, then comparing options by total monthly cost is the best way to shop for the lowest rate for you.
Even better, 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 ideal way to find the right electricity rate plan for your home.
Compare Power does all the complicated math for you in an instant. What takes hours inside a spreadsheet is now solved in just seconds.
We put the power in your hands, taking what would amount to hours of investigation, spreadsheets, and computations across hundreds of offers to guide you to the best electricity rate plan for your household's usage.
We clarify the fine print, disclosing the various charges, so you'll know exactly where your money is going and what to expect on your monthly bill.
We then help you sign up with your chosen energy provider without leaving our service.
The bottom line is you should know your expected or historical usage before selecting the best electricity plan for your home.
If you don't know your usage, estimate
If you cannot acquire 12 months of historical usage or own a brand new home, the next best thing is to estimate how much energy you will use in an average month.
While not as optimal as having all the previous 12 months of usage, estimating your average usage is better than blindly picking the first plan you see advertised by an electricity provider at a specific usage that isn't what you'll consume.
Use Compare Power to find the best electricity plan for your specific usage.
Moving to Port Isabel: Setting up Electricity
If this is your first time setting up electricity service in Port Isabel, 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: 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 it's time to renew your existing plan or possibly switch plans.
Switching Electricity Companies in Port Isabel
Switching is good. Market conditions are constantly in flux, so shopping for a lower rate each year is vital when your contract expires.
Your existing electricity company will typically raise your electricity rate once your contract 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 energy providers.
Switching can save you hundreds or thousands of dollars yearly on your electricity 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 electricity provider will handle everything, including canceling service with your previous company.
Your lights stay on when you switch. Electricity in Port Isabel 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 choose 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. You can set a future start date with most companies up to 60 days in advance.
And even if you're well inside your contract, savings achieved on your monthly bill by switching providers may outweigh the fee of breaking your existing contract.
If you're ready to switch and would like to know how to find the best plan remember that knowing your usage is the best way to find the lowest price.
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.
