McKinney is one of the fastest-growing cities in the United States — a Collin County suburb north of Dallas that has transformed from a small historic town into a major residential market of nearly 250,000. Its housing stock is predominantly large single-family homes built in the 1990s through the present, with an active new construction market continuing to add units in its northern and western corridors. Every McKinney address is within Oncor Electric Delivery's deregulated service territory. Like neighboring Plano and Frisco, McKinney's large-home profile means summer electricity usage that regularly exceeds the 1,000 kWh advertised benchmark — often by 50% or more.

The short answer

McKinney ZIP codes 75069–75072 are Oncor Electric Delivery territory — fully deregulated. Fixed-rate plans as of May 2026 advertise 9.5–13.5¢/kWh at 1,000 kWh. Collin County homes are large — 2,200–4,000 sq ft is typical — driving summer usage of 1,400–2,000 kWh. The 2,000 kWh EFL tier is the most predictive pricing point for McKinney households.

Oncor in McKinney — Collin County Market

Oncor Electric Delivery serves McKinney and all of Collin County as the regulated TDU. Oncor's TDSP charges — a fixed monthly customer fee and a per-kWh distribution charge regulated by the PUCT — appear on every McKinney bill. At 1,000 kWh, these charges typically add $8–$13. At 2,000 kWh in peak summer, the delivery component rises to $16–$22.

McKinney sits at the northern edge of the DFW metroplex — the same Oncor service territory that covers Dallas, Plano, and Frisco. Plan availability is equivalent across the entire Oncor footprint, meaning McKinney residents access 60–90 active plans from 20+ providers.

A Texas example

David and Amy live in a 3,000 sq ft home in north McKinney (75071), built in 2018. August usage: 1,880 kWh. Their plan was advertised at 10.5¢/kWh at 1,000 kWh — they expected around $105 for energy. Actual August energy charge: $193.42 at the interpolated rate of 10.29¢/kWh. Oncor TDSP added $24, taxes $11, and a $9.95 base charge completed the $238.37 total bill. A plan comparison that month showed a plan with the same 1,000 kWh advertised rate but a lower 2,000 kWh rate that would have produced a total bill of $211.50 — a $26.87 monthly saving, or $134 over five summer months.

Why the 2,000 kWh EFL Tier Matters Most in McKinney

McKinney's Collin County housing stock is large by Texas standards. A 3,000 sq ft home in north McKinney with a 16-SEER HVAC running on a 100°F August day in DFW will use 55–75 kWh per day. Over 31 August days, that is 1,700–2,300 kWh. For these households, the 1,000 kWh advertised rate is essentially irrelevant — it describes usage that the home exceeds by the 10th of the month.

The 2,000 kWh EFL tier — the third and final required disclosure price on every Electricity Facts Label — is where McKinney summer comparison should start. A plan with a higher advertised rate but a significantly lower 2,000 kWh rate will almost always win for large-home McKinney households. This is the core value of interpolated comparison: it shows you exactly which plan wins at your real usage level.

The math

McKinney home, August, 1,900 kWh. Plan A: 10.5¢ at 1,000 kWh, 9.0¢ at 2,000 kWh — interpolated rate at 1,900 kWh: 9.15¢, energy charge $173.85. Plan B: 9.8¢ flat at all EFL tiers — energy charge $186.20. Plan A saves $12.35/month at this usage level — even though its advertised 1,000 kWh rate is 0.7¢ higher. Over five summer months: $61.75 saved. The headline rate pointed squarely to the wrong plan.

Smart move

New-construction McKinney homes in 75071 are often equipped with smart thermostats from the builder. Many homeowners accept the default schedule — typically a constant setpoint throughout the day. Setting the thermostat to pre-cool to 72°F between 6–9 AM and raise to 78–80°F between 2–8 PM (peak ERCOT hours) reduces daily peak demand without meaningfully reducing comfort. At 1,900 kWh/month, a 10% usage reduction saves 190 kWh — about $17 at 9¢/kWh — every August month without switching plans.

Key Takeaways

McKinney ZIP codes 75069–75072 are Oncor territory — delivery charges are fixed. Large Collin County homes drive summer usage of 1,400–2,200 kWh — making the 2,000 kWh EFL tier the most relevant comparison point, not the 1,000 kWh advertised rate. Compare plans at your actual usage level for meaningful savings.
