Lewisville, TX
Ambit Energy Electric Service, Rates & Plans

Lewisville is a growing suburban city in Denton County, located north of Dallas along Lake Lewisville and serving as a major residential and employment hub in the region. When you move to Lewisville, you'll work with two separate electricity providers. Oncor Electric Delivery is the regulated utility that owns and maintains the poles, wires, and meters in your area—call Oncor for any outages or service interruptions. For your electricity plan, billing, and customer service, you'll contact a retail electricity provider such as Ambit Energy. This two-provider setup is standard for Texas's deregulated electricity market and gives you the freedom to choose your rate plan while Oncor handles the reliable delivery infrastructure. Lewisville's summer heat demands significant air conditioning, with typical high temperatures reaching the low to mid-90s and cooling costs representing a major portion of yearly electricity use. Winter months are mild and require minimal heating, making summer consumption the primary driver of annual usage. Most Lewisville households use between 1,000 and 2,000 kilowatt-hours per month during peak cooling season. When comparing rate plans, focus on pricing at the 1,000 to 2,000 kWh tier rather than promotional rates advertised at 500 kWh, since that tier reflects where most residences actually fall over a full 12-month contract and delivers the best genuine savings for your situation.
