Quick answer

Carrollton is a deregulated market served by Oncor, so you choose your retail provider while Oncor owns the wires. The city is notably diverse and unusually spans three counties (Dallas, Denton, and Collin). Base charges a flat 8¢/kWh energy rate plus Oncor delivery and a flat monthly membership — no teaser rates.

The real question

What should you pay in Carrollton?

There's no single "right" number — it depends on your home, your usage, and your plan. But a lot of Texans pay more than they expect, and it's usually not the headline rate's fault. Many plans advertise a low rate that only applies inside a narrow usage band, or hand back a "bill credit" only if you land on exactly the right kilowatt-hours. Miss the threshold and the effective rate jumps.

The honest way to know what you should pay is to compare the all-in cost — energy plus Oncor delivery plus any fees — at your actual usage. Base removes the guesswork: one flat 8¢/kWh energy charge and a flat monthly membership, with no teaser rates and no bill-credit games.

Takes about two minutes.

The wires

Who delivers your power in Carrollton?

Oncor is the largest transmission and distribution utility in Texas. It owns and maintains the poles, wires, and meter across the Dallas–Fort Worth area. Oncor doesn't sell electricity and you don't choose it — it's set by your address, and it handles outages and restoration regardless of which retail provider you pick.

Local context

How electricity rates work in Carrollton

Carrollton is one of the most diverse suburbs in DFW, with a large and well-established Asian and Korean-American community — about 43% of residents speak a language other than English at home — and above-metro incomes (median household income around $102,000). It's also geographically unusual, spanning three counties: Dallas, Denton, and Collin.

For electricity, though, Carrollton is straightforward Oncor territory across all three counties, fully deregulated. You choose your retail provider, Oncor delivers the power, and the delivery charges are the same no matter who you pick.

Why are Carrollton bills highest in summer?

Carrollton shares the North Texas heat — about 20 days a year over 100°F on average — so summer air conditioning is the main driver of electricity bills, the same as across the rest of the DFW Metroplex.

Carrollton, the grid, and backup power

Carrollton is on the ERCOT grid that nearly collapsed during Winter Storm Uri in February 2021. A home battery is a separate product that backs up your own home during an outage; it doesn't change Oncor's wires service, which is identical for every retail provider.
