Oncor Electric Delivery still owns the poles, wires, and meters and restores outages no matter which plan you pick. Your retail plan only sets your price, term, and billing.
Pricing varies by ZIP and usage from Old Town and Castle Hills to Vista Ridge, so a smart comparison starts with your address, not a single "Lewisville average."
Lewisville sits in Denton County in the Dallas-Fort Worth metroplex, where Oncor Electric Delivery is the regulated Transmission and Distribution Utility (TDU). They own the poles, wires, and meters, restore outages, and set the delivery charges that are the same for every retail provider.
From Old Town along Main Street to the neighborhoods around Lewisville Lake, the city runs on the Oncor grid. Whichever retail plan you choose, Oncor still delivers the power and restores outages, so you are free to pick Ambit purely on price and rewards.

Lewisville is a fast-growing suburb in Denton County, anchoring the northern side of the Dallas-Fort Worth metroplex along Interstate 35E. It grew up around the railroad and Old Town Main Street, and today wraps the shoreline of Lewisville Lake, a major recreation draw for boating, fishing, and lakeside parks. Master-planned communities such as Castle Hills and the retail and entertainment hub at Vista Ridge have helped turn a small farming town into a regional commuter and shopping center. In a deregulated Texas market, that growth means Lewisville homeowners can shop the open market for their own electricity plan instead of taking whatever a single utility offers.
Report outages to your local utility, Oncor Electric Delivery, at (888) 313-4747 — not to your retail provider. They restore power no matter which plan you have.
