Round Rock’s Trusted Energy Provider

If you call Round Rock your home, you’ll likely find much to enjoy in this classic Texas town. You are within commuting distance to Austin, but many people find work locally in the life sciences, financial services and technology sectors.

Round Rock is one of the fastest growing cities in the country and it’s not hard to understand why. You can enjoy a stroll past stately homes and the charming shops of Main Street, stock up on local crafts and produce on Market Day or shop national chains in the Round Rock Premium Outlets®. Its award-winning schools and reputation for safety can make it ideal for families. As the “Sports Capital of Texas,” Round Rock is also home to facilities that have earned national acclaim.

The town got its start as a place where horses, wagons and herds of cattle could safely cross Brushy Creek in relatively low water. A round rock, still visible today, marked the crossing spot. The charming “old town” area of historic buildings was the backdrop of the notorious gunfight between a Texas Ranger and a train robber in 1878.

Things have calmed down since then, and cattle no longer slosh across the creek. Now you can enjoy every modern convenience. When you choose Constellation, you are choosing one of the leading retail electric providers in Round Rock and have options to choose from when it comes to electricity rates and plans.
