Since 2001, Gexa Energy has served more than 1.8 million Texas households.1 That kind of longevity in a deregulated market comes from offering plans that actually fit the way people live, not just a single generic option.

*Competitor rates are each provider's own published average price per kWh at 1,000 kWh of monthly usage for this service area, including TDU delivery charges, as listed on the provider's website on November 12, 2026 at 10:16 AM CT. Rates vary by utility service area and change frequently. Estimated monthly bills assume 1,000 kWh of usage. Always review each plan's Electricity Facts Label (EFL) for complete and current pricing, fees and terms.
Gexa Energy's plan lineup covers a wide range of home sizes, usage patterns, and living habits, so there's rarely a single "right answer" for every household. The Electricity Facts Label (EFL) for each plan is the best place to confirm exact pricing, terms, and eligibility before you commit.
A fixed-rate plan locks in your Energy Charge for the full length of your contract term. That kind of consistency can be especially useful heading into a Central Texas summer, when usage (and the temptation to worry about your bill) tends to spike.
Certain Gexa Energy plans include a bill credit once your household's monthly usage reaches the threshold listed on that plan's Electricity Facts Label. Reach the threshold, and the credit applies to your bill. Fall short, and it doesn't kick in for that billing cycle. The best way to know if this structure fits your home is to line up your past bills against the specific threshold listed in the EFL you're considering.
Free Electricity plans build in set windows, in our case weekends, when qualifying usage is billed at $0. If your household can shift laundry, charging, or other electricity-heavy tasks into those windows, this structure may be worth a closer look. Keep in mind the other charges may still apply.
Some Gexa Energy plans come bundled with smart thermostat technology and energy management tools. Paired with Gexa MyAccount and the Gexa Energy Mobile App, these features give you a clearer picture of your usage in real time, which can be especially handy during Round Rock's longer cooling season.
If your home has a qualifying solar installation, Gexa Energy's solar buyback plans let you earn bill credits for eligible excess electricity your system sends back to the grid. Your plan's Electricity Facts Label and Product-Specific Terms outline exactly how those credits are calculated.
If you're already charging an EV at home, Gexa Energy offers plans built around that routine. These plans provide an energy charge credit during eligible overnight hours, helping you get more value out of charging while everyone's asleep. TDU delivery charges still apply during every charging window.
With a variable-price plan, your Energy Charge can move up or down each month based on market conditions. That flexibility appeals to some households, particularly those who aren't planning to stay in one place long or who'd rather avoid a longer contract commitment.
Flat rate plans hold your Energy Charge steady as long as your usage stays within the range specified in the plan. Go over that range, and the extra kilowatt-hours are billed at an additional rate. For households with fairly predictable monthly usage, this structure can offer another path to a steadier bill.
In Round Rock, electricity bills are primarily shaped by:
Hot Central Texas summers often increase electricity usage as air conditioners run longer to keep homes comfortable.
Square footage, insulation levels, home age, and overall energy efficiency can all influence monthly electricity consumption.
Occupancy, remote work setups, electric vehicle charging, appliance use, and other daily habits affect how much electricity a household uses.
Fixed-rate plans, variable-price plans, usage credits, and Free Electricity plans all calculate energy charges differently.
Regulated Oncor Electric delivery charges are included in your monthly electricity charges regardless of which Retail Electric Provider you choose.
Estimated electricity bills in Round Rock can vary based on seasonal energy use and the current price of your selected plan. Using Gexa's average available price of 16.6¢/kWh, the estimated average monthly electricity bill in Round Rock is $165.59. For a typical home, the average monthly bill is approximately $192, while apartment residents typically pay around $128 per month. This equals estimated annual electricity costs of $2,304 for a home and $1,532 for an apartment.
A typical Round Rock home's bill ranges from about $111 in Feb to $302 in Jul. For an apartment, bills range from $94 in Nov to $171 in Jul.
*The chart uses live plan pricing and seasonal usage data to provide a more accurate estimate than a static annual average. Estimates are modeled using Gexa's average available rate at 1,000 kWh and typical seasonal usage patterns. Actual bills will vary based on electricity usage, plan selection, and applicable TDU delivery charges.
The right plan for your household comes down to three things: how much electricity you use, when you tend to use it, and how much predictability you want in your monthly bill.
A single month's bill only tells part of the story, while looking at a full year of usage gives you a much better sense of how your household's habits shift with the seasons, especially given how much Round Rock's summer heat can drive up usage compared to spring or fall.
The lowest advertised rate isn't always the plan that ends up saving you the most. It pays to weigh contract length, plan structure, and extra features like smart thermostat tools, solar buyback, or EV charging credits. Reading the Electricity Facts Label (EFL) before you enroll is the best way to confirm exactly how a plan works, from pricing to contract terms to eligibility requirements.

Yes, Round Rock is part of Texas' deregulated electricity market, which means most residents and businesses can choose their own Retail Electric Provider (REP) instead of defaulting to a single utility. That choice lets you compare plans, pricing, and features before deciding what fits your household.
Your electricity rate is shaped by your chosen plan, your contract terms, and current market conditions. Your monthly electricity charges are a different equation entirely, driven by how much electricity your household uses, the plan structure you've selected, and TDU delivery charges. Reviewing the Electricity Facts Label (EFL) before enrolling helps you understand how these two pieces fit together on your actual bill.
Round Rock is served by Oncor Electric Delivery, the Transmission and Distribution Utility (TDU) responsible for maintaining power lines and restoring service during outages. Gexa Energy, as your Retail Electric Provider, handles your plan, billing, and customer support instead.
