Frisco grew from 33,000 residents in 2000 to over 230,000 by the mid-2020s, making it one of the fastest-growing cities in the United States. That growth brought thousands of large, energy-intensive new homes — master-planned communities with 2,500–4,000 sq ft floor plans, pools, and multiple HVAC zones — into the deregulated Texas electricity market. For Frisco households, comparing plans by their true cost at high usage levels matters more than for smaller-home cities.

Oncor in Frisco — The Fixed Layer Under Every Bill

Oncor Electric Delivery serves all of Frisco across Collin and Denton Counties. Oncor is responsible for the physical delivery of electricity — substations, distribution lines, and the smart meter at your address. Oncor's TDSP charges are regulated by the PUCT and are the same for every Frisco customer regardless of which REP they use.

Your retail electric provider (REP) is the competitive layer — the company that prices and sells you electricity. REPs buy power in ERCOT's wholesale market and pass it to you through a plan. Switching your REP has no effect on Oncor's delivery; your lights stay on uninterrupted. Frisco typically has 60–90 active plans available across 20+ REPs.

Why Frisco's New Homes Drive Higher Usage

The residential construction boom in Frisco produced a housing stock that skews larger and newer than most Texas cities. Master-planned communities like Starwood, Newman Village, and Stonebriar contain primarily large single-family homes. Newer homes tend to be better insulated than older stock, but their greater square footage means the total cooling load is still high.

According to EIA residential consumption data, air conditioning accounts for roughly 50–60% of summer electricity usage in a Texas home. A 3,000 sq ft Frisco home running a standard central AC system during a 100°F North Texas August day will often consume 70–90 kWh per day — that is 2,100–2,700 kWh for the month. At those usage levels, the 2,000 kWh tier on the EFL becomes the most relevant pricing point, not the 1,000 kWh figure in the advertisement.

Frisco ZIP Code Plan Availability

ZIP	Area	Housing Character
75034	West Frisco / Stonebriar area	Large homes, established master-planned communities
75035	Central Frisco	Mix of mid-sized and large suburban homes
75036	North Frisco / newer development	Newer construction, high proportion of large homes

Choosing the Right Plan for a Large Frisco Home

For high-usage homes, two plan characteristics matter more than the advertised rate. First, the rate at the 2,000 kWh EFL tier — if your home uses 1,800+ kWh in summer, this number is more representative of your actual summer cost than the 1,000 kWh figure. Second, the base charge — a plan with a $15/month base charge and a lower per-kWh rate often outperforms a plan with no base charge and a higher per-kWh rate at usage levels above 1,500 kWh.

The True Cost Calculator lets you enter your actual monthly usage for any plan and see the estimated annual bill. For Frisco homeowners, running this calculation at your typical summer peak (1,700–2,200 kWh) is essential — the ranking of plans by cost can change significantly between the 1,000 kWh and 2,000 kWh benchmarks.

Key Takeaways

All Frisco ZIPs are Oncor territory — TDU charges are uniform and non-negotiable. Your REP and plan are the variables. Frisco's large, newer homes frequently push summer usage above 1,800 kWh, making the 1,000 kWh advertised rate an especially poor proxy for real cost. Compare plans by estimated bill at your actual usage level, paying particular attention to the 2,000 kWh EFL tier if your summer usage typically exceeds 1,500 kWh.

Frequently Asked Questions

What are typical electricity rates in Frisco, Texas?

As of May 2026, fixed-rate plans in Frisco (Oncor territory) typically advertise 9.0–13.0 cents per kWh at the 1,000 kWh EFL level.

Search by your Frisco ZIP for a true-cost calculation.

Who is the electricity TDU for Frisco?

Oncor Electric Delivery serves all of Frisco. Frisco spans Collin and Denton Counties — both are within Oncor's ERCOT service territory. Oncor owns the delivery infrastructure; your retail electric provider (REP) handles pricing and billing. You can switch REPs freely; you cannot change your TDU.

Does Frisco's rapid growth affect electricity plan availability?

Frisco's population growth has been among the fastest in the country over the past decade, and its housing stock skews toward new, large single-family homes. New construction connects directly to Oncor's distribution network and enters the competitive market immediately. Plan availability in Frisco ZIPs is typically broad — 60–90 active plans across 20+ providers.

Are electricity rates different in Frisco vs. Plano or McKinney?

Frisco, Plano, and McKinney are all Oncor territory, so TDU delivery charges are identical. Most major REPs file the same plans across Collin County and the broader DFW metro. Occasional ZIP-specific promotions aside, plan pricing is effectively the same across these North Dallas suburbs.

What ZIP codes cover Frisco electricity customers?

Frisco's primary residential ZIP codes are 75034, 75035, and 75036. Portions of newer development may carry adjacent ZIPs as master-planned communities expand. All fall within Oncor's deregulated service area. Enter your specific ZIP for the most accurate plan results.

Enter your Frisco ZIP in the search tool or on the PUCT's Power to Choose site (powertochoose.org), select a plan, and complete the signup online.
