Quick answer

McKinney is a deregulated market served by Oncor, so you choose your retail provider while Oncor owns the wires. It's among Texas's top-5 fastest-growing cities and has more than doubled in about 20 years, so new single-family homes are everywhere. Base charges a flat 8¢/kWh energy rate plus Oncor delivery and a flat monthly membership.

The real question

What should you pay in McKinney?

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.

The wires

Who delivers your power in McKinney?

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 McKinney

McKinney was among Texas's top-5 fastest-growing cities in 2024, adding more than 11,000 residents in a single year on its way past 240,000 — a population that has more than doubled in roughly two decades. It's the Collin County seat, known for blending a charming historic downtown with rapid suburban growth.

That growth means tens of thousands of relatively new single-family homes — good candidates for solar and battery — across a city that's a perennial 'best place to live.' Power is delivered by Oncor and the retail market is wide open, so comparing the all-in cost of a plan is worthwhile.

Why are McKinney bills highest in summer?

McKinney is in Collin County under the North Texas heat — about 20 days a year over 100°F on average. With a lot of newer, larger homes, summer cooling tends to push usage above the Texas average from June through September.

McKinney, the grid, and backup power

McKinney 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 or restoration, which are identical across retail providers.

Apples to apples
