Who provides electricity in Frisco?
Two utilities do: Oncor and CoServ. A utility owns the poles and wires, and it fixes them when the power goes out. The City of Frisco is not one of them. Its resident guide lists CoServ and Oncor, and it points to Power to Choose for shopping.
| Utility | What it is | Can you pick a power company? |
|---|---|---|
| Oncor | A delivery company. It owns the lines and does not sell power. | Yes. You pick from the plans on Power to Choose. |
| CoServ | A co-op based in Corinth, owned by the people it serves. It delivers and sells the power. | No. CoServ sets the rate for its members. |
The state calls the choice program "customer choice." A co-op or a city utility may join it at any time, says the Commission's own FAQ on these utilities. Until one joins, the only price for its members is its own. On Oncor's lines, the company you pick is called a retail electric provider, or REP. Our REP guide shows what it does and what Oncor does.
Two City buildings sit side by side on Research Road. The 2021 City letter lists its Public Works center at 11300 Research Rd on CoServ. It lists the pump station at 11310 Research Rd on Oncor. Next-door neighbors can have different utilities.
Frisco is not the only split city nearby. McKinney, to the east, has Oncor, CoServ and a second co-op, GCEC.
What does electricity cost in Frisco?
It depends on your utility. An Oncor home pays the plan it picks, and a CoServ home pays CoServ's rate. These prices are the average cents per kWh at three levels of use. They include delivery and the monthly charges, so the two sides line up. Taxes are not in them. The Oncor-area rows come from plans anyone in that area can buy. The CoServ row is the Standard rate plus its $15 monthly charge.
| Plan | 500 kWh | 1,000 kWh | 2,000 kWh |
|---|---|---|---|
| Cheapest plain 12-month plan, Oncor area | 12.1¢ | 12.0¢ | 11.8¢ |
| Middle plain 12-month plan, Oncor area | 13.7¢ | 13.2¢ | 13.0¢ |
| CoServ Standard rate | 14.48¢ | 12.98¢ | 12.23¢ |
"Plain" means a fixed rate for 12 months, with no bill credit or usage fee flag, not prepaid and not time-of-use. Our guide to the cheapest plans covers every type. CoServ's price moves each month. It adds or takes off a power-cost adjustment, and that was minus 1.3¢ in October and minus 1.0¢ in September.
Pick your utility to see what CoServ's Standard rate costs next to plans in the Oncor area.

This is a guide, not a quote. It leaves out taxes, bill credits and fees. A plan's facts label shows the price you would pay, and CoServ's rate page shows its current month.
Which utility serves my Frisco address?
Your bill or your meter's ESI ID gives the sure answer. A map can only narrow it down. CoServ publishes a map of its service boundary, and we laid it over the Census Bureau's lines for Frisco and measured land. All of Frisco sits inside CoServ's boundary. On 44.7% of the city, CoServ is the only company with a certificate. On 55.2%, CoServ shares the land with Oncor.
Our measurement of CoServ's boundary map over Census city lines, using flat-map area math. Shared land means more than one company holds a certificate. It does not show who serves a house. CoServ last edited the map layer on December 12, 2018, so treat the edges as approximate.
A ZIP code is a rough guide too. Here is the land in each Frisco ZIP, split the same way. We counted only the part of each ZIP that lies inside Frisco.
| ZIP | Share of Frisco's land | CoServ alone | CoServ and Oncor share |
|---|---|---|---|
| 75033 | 31.2% | 53.5% | 46.5% |
| 75034 | 23.3% | 25.8% | 74.2% |
| 75035 | 35.0% | 33.7% | 66.3% |
| 75036 | 9.0% | 99.5% | 0.5% |
Even a ZIP that is mostly shared land has CoServ homes in it. Three sure ways to check:
- 1Read your bill.
The company that sends it is CoServ, or it is a power company with "delivered by Oncor" on it.
- 2Look up your ESI ID.
This is the ID of your meter. Oncor's lookup finds it from an address, and our guide to who your electric utility is shows how to read it. If Oncor finds no meter for your address, ask CoServ.
- 3Ask CoServ.
It has a map for your address and a Customer Care line at 940-321-7800, Monday to Friday, 8 a.m. to 5 p.m. Central.
What if CoServ serves my Frisco home?
Then CoServ is your only power company, and you choose among its rates, not from a plan list. CoServ says its members never need to shop around. You start on the Standard rate, and a CoServ agent can look at your use and suggest a better fit. All of its residential rates include the energy and the wires.
| Rate | Price per kWh | Who it suits |
|---|---|---|
| Standard | 11.48¢ | Everyone. It is the default. |
| Solar Savings | 11.67¢ | Anyone who wants 100% solar power and has no panels |
| Summer Savings | 7.87¢ off-peak, 20.23¢ on-peak | People who can shift use away from 3 p.m. to 8 p.m. from May to October |
An Oncor home that wants 100% renewable power can buy a plan for it instead. Our guide to green energy plans shows what those cost beside plain plans.
Starting service costs a $40 connection fee. A deposit depends on a credit check and, per CoServ, will not exceed $300. CoServ refunds it after 12 on-time bills in a row, or when you close the account. The Customer Care line is 940-321-7800.
CoServ and Oncor both appear on Power to Choose results for some Frisco ZIP codes. If CoServ serves you, ignore the plan list. Those plans are not open to you.
Do the City's own records show both utilities?
Yes. In October 2021, the City of Frisco sent the Commission a letter on its water and sewer sites, to meet a 2021 state law. The letter lists which utility powers each site. We placed the sites that give map points on CoServ's boundary map.
The City lists its Public Works center, pump stations and lift stations on CoServ. Of the 17 we could place, 10 sit on CoServ-only land and 7 on shared land.
The City lists tanks and pump sites on Oncor. All 6 sit on shared land. None sits on land that only CoServ holds.
That fits the map. If your street is on land that only CoServ holds, CoServ serves you. On shared land, either utility may, so check your bill. The letter is from 2021, and Frisco has grown since.
What is on a Frisco electric bill?
An energy charge, a delivery charge, a monthly charge and the city's sales tax. Who sets each one depends on your utility, and the part you can shop is smaller than most people think.
| Line | Oncor homes | CoServ homes |
|---|---|---|
| Energy charge | Your power company. You can shop it. | CoServ. One rate set by the co-op. |
| Delivery charge | Oncor, at a rate the state approves. Same for every company. | Already inside CoServ's rate |
| Monthly or base charge | Part of the plan you pick | $15 on the residential rates |
| City sales tax | Frisco is on the Comptroller's list of cities that tax home power | Same city tax |
Our Oncor guide breaks down the delivery charge an Oncor home pays. Look for a city tax line on the bill too. The Comptroller's list covers cities that charge a local sales tax on home gas and electricity. Frisco is on it. The city sets the rate, and it is not part of any plan price.
How do you start electric service in Frisco?
Find your utility first. Then the choices open up, or they do not.
- Find the utilityCheck the last bill, ask the seller or landlord, or look up the address. This tells you if you can shop.
- Oncor home: pick a planCompare plans for your ZIP. Open the facts label for each and read the 500, 1,000 and 2,000 kWh rows.
- CoServ home: applyAsk CoServ to start service. Plan on the $40 fee and a possible deposit.
- Set the start dateChoose the day you get the keys. Do this before the move so there is no gap.
Our guides to setting up electricity and same-day service walk through the steps for an Oncor home.
Who do you call when the power goes out in Frisco?
Call the utility that owns your lines, Oncor or CoServ. Your power company cannot fix them. If you are not sure, the City's Public Works office can help.
| Utility | Report an outage | Note |
|---|---|---|
| Oncor | 888-313-4747, or text OUT to 66267 | Oncor fixes the lines for every company on its system |
| CoServ | 855-938-3496 (electric emergency) | The co-op fixes its own lines |
| City of Frisco | 972-292-5800, Public Works | For street lights on major roads, or when you are not sure |
Our guide to reporting a power outage lists what to do while you wait.
What should you check before you sign a Frisco plan?
Make sure Oncor serves your home first. Then check the price, the term, the label and the cancel fee.
- You know your utility is Oncor
- The price is fixed for the whole term
- The facts label shows a fair price at 500, 1,000 and 2,000 kWh
- The cancel fee is small, or there is none
- Signing a plan before you know if CoServ serves you. It is not open to you.
- A bill credit you must earn, which can vanish if you use a little too little
- A deposit or fee that is not necessary. Ask what it is for.
- A short term of one to three months, when the price can jump at the end
Our guide to Power to Choose shows how the plan list works. A plan is a contract, so keep the facts label you signed.
If CoServ sends your bill, its rate is your price, so ask CoServ which rate fits your use. If your bill says Oncor, compare plans at your ZIP before you sign.
Compare plans at my ZIPA partner runs the plan finder. If you sign up, it may pay us a fee, and that never moves a rating or a score.
Questions, answered
Who is the electric company in Frisco?
There are two utilities. Oncor serves part of the city and CoServ serves the rest. If you are on Oncor, you pick a power company. If you are on CoServ, the co-op is your only company.
Can I choose my electricity company in Frisco?
Only if Oncor serves your home. CoServ members cannot pick, because CoServ sets its own rates. Check your bill or your ESI ID to see which you have.
Is Frisco on Oncor or CoServ?
Both. Our map math finds CoServ alone on 44.7% of the city's land and shared with Oncor on 55.2%. The City's own 2021 letter lists sites on both.
Is CoServ cheaper than an Oncor plan in Frisco?
It depends on your use. At 1,000 kWh, CoServ Standard was 12.98¢ in October 2026. The middle plain plan in the Oncor area was 13.2¢ and the cheapest was 12.0¢. Use the tool above for 500 and 2,000 kWh too.
Which Frisco ZIP code is almost all CoServ?
75036. In our map math, CoServ alone holds 99.5% of the Frisco land in that ZIP, so a home there is most likely on CoServ. Your bill is the sure answer.
Could CoServ join customer choice?
The Commission's FAQ says a co-op may join customer choice at any time. CoServ's own site says its members never need to shop around, so check its site for news.
How much does it cost to start CoServ service?
CoServ charges a $40 connection fee. A deposit may apply, based on a credit check, and it will not exceed $300.
Does the City of Frisco sell electricity?
No. The City's resident guide lists CoServ and Oncor for electricity. The City contracts with both for street lights, and its Public Works office takes calls at 972-292-5800 when you do not know whose light it is.
