Watt Owl may receive a commission from providers when you sign up through our site. Our rankings are based solely on estimated cost at your usage level—commissions never influence plan placement.
Why do our rates look different from other sites?
Most comparison sites show the rate from your plan's Electricity Facts Label at exactly 1,000 kWh. We estimate your total monthly cost — including Texas-New Mexico Power delivery charges — at your selected usage level. This gives you a more complete picture of what a plan is likely to cost, not just the energy rate.

What Affects My Electric Bill in Lewisville?

Homes in Lewisville use an average of 1,089 kWh per month, or about 13,065 kWh per year. Usage peaks in July at around 1,542 kWh due to air conditioning demand, and drops to its lowest in January at around 850 kWh.
The best time to switch is during shoulder months (March–April and October–November) when demand is lower and providers often offer competitive rates. However, you can switch anytime with no interruption to your service. Currently, rates in Lewisville start as low as 9.13¢/kWh for fixed-rate plans.
When your contract ends, your REP is required to send an expiration notice at least 14 days before your contract expires. If you don't select a new plan before expiration, you'll typically be moved to a month-to-month variable-rate plan, which is often more expensive than a fixed-rate contract. We recommend shopping for a new plan at least two weeks before your contract ends to ensure a smooth transition.
Switching providers is free and straightforward. Choose a new plan, complete the enrollment with the new REP, and they handle notifying your current provider. Your power stays on throughout the process — Oncor Electric Delivery continues delivering electricity regardless of which REP you choose. Most switches take effect within one to three business days after your enrollment is processed.
