Gexa Energy offers a range of plans designed for different home sizes, lifestyles, and usage patterns. Some customers want steady monthly Energy Charges, while others are looking for credits tied to usage, solar, or overnight EV charging.
Fixed-rate electricity plans keep your Energy Charge steady throughout your contract term, which can make monthly budgeting easier. That kind of consistency can be especially helpful in Lewisville, where summer cooling often pushes electricity use higher for several months at a time.
Some Gexa Energy plans include a bill credit when your monthly usage reaches a plan-specific threshold listed in the Electricity Facts Label. For example, a qualifying plan may offer a bill credit when your household reaches 1,000 kWh during the billing cycle. If you do not reach that threshold, the credit will not apply that month. These plans can work well for households that already have a good sense of how much electricity they use each month.
Gexa offers a Free Weekends electricity plan that offers free electricity usage from 12:00 AM Friday to 12:00 AM Monday. This plan can be a good fit for households that can shift some of their usage into the qualifying window.
Keeping cooling costs in check matters more during the hottest Texas months, and that is where smart thermostat and energy management plans can help. Gexa Energy offers a plan that includes smart thermostat technology and tools designed to help you better understand your home’s electricity usage. With Gexa MyAccount and the Gexa Energy Mobile App, you can review your electricity usage, monitor account activity, and make adjustments that support your comfort goals.
For homeowners with a qualifying rooftop solar system, Gexa Energy’s solar buyback plans provide bill credits for eligible excess electricity your system sends back to the grid. Solar buyback can be a helpful option for Lewisville homeowners who want to get more value from their solar investment. Be sure to review the Electricity Facts Label and Product-Specific Terms so you understand how excess energy credits are calculated.
If you charge an electric vehicle at home, Gexa Energy offers plans designed around overnight charging habits. These plans provide an energy charge credit when your vehicle charges during eligible overnight hours, helping you align your routine with off-peak periods.
Variable-price plans offer flexibility because your Energy Charge can change from month to month based on electricity market conditions. That can be useful for customers who do not want a long commitment, but it also means monthly electricity charges are generally less predictable than they are with a fixed-rate plan. If you expect to move soon or prefer a plan without a longer contract term, a variable-price plan may be worth considering.
Flat rate plans provide a consistent monthly Energy Charge while your electricity usage stays within the plan’s specified usage range. If your household goes beyond that range, additional Energy Charges apply to the extra kilowatt-hours used. This type of plan can work well for households with stable usage and a good sense of their monthly energy needs. Reviewing your past bills can help you decide whether a flat rate plan fits the way your home uses electricity.
The biggest factors that affect Lewisville electricity bills include:
Air conditioning is often the largest contributor to household electricity use during the hot summer months.
Lewisville includes a mix of established neighborhoods, lake-area homes, and newer developments, all of which can influence electricity usage.
Occupancy, appliance use, work-from-home schedules, entertainment systems, and overnight EV charging can all affect monthly consumption.
Fixed-rate plans, variable-price plans, usage credit plans, and Free Electricity plans all calculate Energy Charges differently.

The right electricity plan isn't simply the one with the lowest advertised rate. It's the one that fits the way your household uses energy every day. Taking a little time to understand your usage patterns, your home, and the features that matter most can help you choose a plan with confidence.
One of the easiest ways to compare electricity plans is to look beyond a single monthly bill. Your electricity usage changes throughout the year, especially in North Texas where summer cooling needs can be very different from winter energy use. Looking at your annual usage gives you a more complete picture of how your home uses electricity and can help you identify plans that better match your lifestyle.
Finding the right electricity plan is about more than comparing advertised rates. Looking at the full picture can help you choose a plan that continues to meet your needs throughout your contract. Before enrolling, review the Electricity Facts Label (EFL) for details about Energy Charges, fees, contract terms, and plan features.
