Looking for an energy provider in Round Rock, Texas, may be daunting due to the numerous providers, countless plans and intricate terms laid out in some energy plan contracts. However, if you take your time to research and compare Texas electricity rates, you may be able to find the best price per kilowatt-hour (kWh) for your needs. We’ve put together a guide to the top electric companies, the best rates and the top energy plans in Texas to help you find the best energy plan for your home in Round Rock.

Best Electricity Rates in Round Rock

To ensure affordability, consider choosing a transparent, no-gimmick fixed-rate plan, which typically has more predictable monthly energy costs.

In the deregulated energy market in Texas, the lowest advertised rate often relies on bill credits for cheap rates. This plan type can cause bill confusion because the promised discount rate only applies if your usage meets very strict requirements. If your usage falls below or rises above the required kilowatt-hour level, your rate can skyrocket. For more predictable costs, we recommend the straightforward options below.

Cheapest Electricity Rates in Round Rock

Check out the table below to find the cheapest Round Rock electricity rates. However, note that some of these energy plans may offer bill credits, which can cause unpredictable energy bills.

While bill credit plans promise low prices, you’ll only enjoy the discounted rate when your energy usage meets very specific monthly kilowatt-hour requirements. If your usage is too low or too high for the required consumption level, you won’t receive the bill credit, and your rates will increase.

However, if your energy usage consistently meets the bill credit requirements, you may be able to save with this plan type. Carefully review the plan’s EFL before signing up for any energy plan.

How To Choose the Best Round Rock Electricity Plan

Energy companies often offer confusing plan options, such as time-of-use plans and bill credit plans, making it challenging to predict monthly bills accurately. To combat this confusion, we suggest you opt for a straightforward, fixed-rate plan with competitive and predictable rates from reputable electricity providers. We recommend plans that span at least 12 months to secure fair and consistent rates for an extended period. It’s crucial to carefully review the plan’s electricity facts label (EFL) for full plan details.

Understanding your energy consumption patterns is vital for accurately estimating your average electricity costs. By visiting the Smart Meter Texas website, you can begin to recognize your energy usage, enabling you to make well-informed decisions about selecting the most suitable energy plan. You can also pull your energy usage from past energy bills. We recommend looking at your usage over an entire year to account for seasonal fluctuations.

Switching Electricity Providers in Round Rock

Switching providers is easy with these three steps.

  1. Enter your ZIP code below to review providers and plans for your Round Rock home.
  2. Identify which plan you’d like to switch to.
  3. Enter your information and switch your provider in less than five minutes.

Round Rock Plan Types

We suggest opting for fixed-rate plans because they are reliable and predictable, ensuring you have more predictable energy bills each month. However, depending on your specific needs, budget or habits, you might consider other energy plan types, such as variable-rate plans, time-of-use plans or bill credit plans. It’s crucial to assess all the available options before committing to one particular electricity plan.

Fixed-Rate Electricity Plans in Round Rock

Fixed-rate plans offer a steady rate per kilowatt-hour for the entire length of your contract, which can range from six to 60 months, although the most common contracts are typically 12 months. Plans with fixed rates ensure pricing stability regardless of your monthly usage or external factors that may increase prices. However, they may also include an early termination fee (ETF) if you cancel your plan before your contract expires.

Prepaid Energy Plans

Prepaid electricity plans, frequently called no-deposit plans, allow customers to pay for their electricity in advance. These plans also do not require credit checks or upfront cash deposits. While a prepaid electricity plan enables you to pay upfront for your usage, it may also come with higher rates than a traditional postpaid energy plan. If you do opt for a no-deposit plan, we recommend Payless Power. Our research indicates that its fixed rates yield more predictable energy costs than those offered by other prepaid light companies.

Variable-Rate Electricity Plans in Round Rock

Unlike fixed-rate plans, variable-rate energy plans charge rates that fluctuate month-to-month. This means your cost per kilowatt-hour can vary monthly based on supply and demand, weather events, natural gas costs and other factors that impact energy rates in Texas. Unless you want to avoid a contract because you need a short-term energy solution, we almost never recommend this plan type. Rates that change every month are almost guaranteed to lead to surprise energy bills.

Solar Buyback Plans in Round Rock

Round Rock residents who have installed their own solar panels may want to consider a solar buyback plan, which allows you to sell surplus electricity back to the grid. By earning bill credits for the excess electricity generated by your solar system, you can offset your energy costs and earn a faster return on your panels. Energy retailers, including Chariot Energy and Rhythm Energy, offer these plans to homeowners across Texas.

Bill Credit Plans Round Rock

When signed up for a bill credit plan, you receive credits applied to your monthly electricity bills when your energy consumption falls within a specified range of kilowatt-hours. If your usage dips below this threshold — or rises above a maximum ceiling or kilowatt-hours — you will likely see a substantial increase in your energy rate. Although these plans often advertise low rates, bill credit plans can lead to higher bills if your energy consumption does not align with the conditions outlined in the contract terms.

Time-of-Use Energy Plans in Round Rock

Time-of-use plans adjust rates based on the time of day or season. They typically charge higher rates during peak hours and discounted — or even $0 — rates during off-peak hours. These plans are sometimes called “free nights and weekends” plans. These plans are designed to encourage customers to use less energy during periods of high demand. However, it can be difficult to know how and when to use the most energy to save money on your monthly energy costs. For this reason, we don’t recommend time-of-use plans for most Texans.

Round Rock’s Utility Company

Oncor serves as the transmission and distribution utility (TDU) responsible for delivering energy to residential and commercial properties in Round Rock, Texas. 

The deregulated market operates on a three-part system that involves generators, TDUs and retail energy providers (REPs). Generators produce electricity using various sources, including natural gas, solar power, wind power, coal and more. Light companies purchase said energy in wholesale auctions with oversight from the Public Utility Commission of Texas (PUCT) and the Electric Reliability Council of Texas (ERCOT). Meanwhile, utility companies deliver that electricity to homes and businesses across the state. 

When dealing with a power outage, contact your utility directly. Utilities are responsible for managing the local grid, which includes addressing blackouts.

Round Rock Commercial Electricity

Many of the top light companies in Round Rock provide commercial electricity services. Because businesses tend to use very large amounts of energy, business energy rates tend to be cheaper than residential prices. According to November 2024 data from the U.S. Energy Information Administration (EIA), commercial rates are currently 8.73 cents per kWh, while residential rates are 15.60 cents per kWh.

Frequently Asked Questions About Round Rock Energy

What company has the cheapest electricity rate in Round Rock?

Gexa Energy, Chariot Energy, Frontier Utilities and 4Change Energy all offer plans with comparably cheap energy rates, starting significantly lower than the statewide average. However, many of these plans rely on bill credits to provide the cheapest energy rates, which can lead to unpredictable energy costs. For more predictable monthly bills, you may want to consider plans from TriEagle Energy or Rhythm Energy.

What is a good price for electricity per kilowatt-hour in Round Rock?

A good rate in the Round Rock area is between 13 and 17 cents per kWh from a stable plan from a reputable provider. The average residential electricity rate in the state is 15.60 cents per kWh, so any comparable rate can be considered fair and good.

What is the best energy provider in Round Rock?

The best energy provider will depend on your energy needs, habits and budget. However,  our top-rated providers include TriEagle Energy, Reliant Energy and Green Mountain Energy. All three providers deliver excellent customer service, competitive energy rates and typically predictable energy bills.

Can you get same-day energy in Round Rock?

Yes, some providers in Round Rock, Texas, offer same-day electricity plans. These plans allow you to get electricity on the same day you sign up for your plan without a waiting period. Many major energy companies, such as Reliant Energy, Gexa Energy and 4Change Energy, offer same-day plans. Before signing up, check the provider’s cut-off time to make sure you can still secure same-day lights.
