There’s always something happening in Harlingen—known as the “Capital City of the Valley.” The town of over 68,000 residents is just 30 miles inland from the Gulf of Mexico, South Padre Island’s beaches and scenic sites like the Laguna Atascosa Wildlife Refuge.

Located in the center of the Rio Grande Valley, Harlingen is part of one of the fastest-growing regions in Texas. Since the 1980s, the Rio Grande Valley population has more than doubled, from just under 600,000 people to nearly 1.4 million—and Harlingen has seen its fair share of this explosive growth.

What makes Harlingen so attractive is the warm tropical weather, an abundance of activities and attractions, as well as a community that is warm and welcoming.

Harlingen is a great spot for birdwatchers as well. Two of the nine World Birding Centers are located in the Rio Grande Valley—the 40-acre Harlingen Thicket and the Arroyo Colorado in the 55-acre Hugh Ramsey Nature Center. Located in the “Central Flyway,” over 400 species of birds have been seen in this area, and visitors come from around the world to catch a glimpse of these exotic migratory birds. The area also attracts golfers, boaters, cyclists, fishermen, hunters, campers and outdoor enthusiasts.

Whether you’re new to town or a long-time member of the community, Reliant is here to help residential customers find the right energy plan and electricity prices for your needs in current electricity markets.

As one of the top Texas electricity companies, we take pride in providing you with the highest level of energy service, easy-to-use tools to help you manage your account, and a wide range of electric plans.
