Electric Company by Address: Free Instant Lookup (2026)

Updated on October 28, 2026

15 min read

To find the electric company for your address, enter it in the lookup tool below or check your latest bill. Every address has a local utility that delivers the power and is set by geography — you cannot change it. But in a deregulated state, that utility only delivers; the supplier who sets your rate is yours to choose. So “who is my electric company” has two answers, and which one you can shop depends on your address.

How do I find out what electric company services my address?

There are three quick ways to find the electric company by address. Fastest is the lookup tool above: type your address and it returns the utility that serves it and, where the market is deregulated, the suppliers you can shop. Second, your most recent electric bill names the delivery utility and, if you have one, your current supplier. Third, your state’s public utility commission publishes service-territory maps. For most people the tool is the shortcut, because service territory follows your address block by block.

Who provides electricity to my address?

Two parties can be involved. The delivery utility — companies like AEP Ohio, ComEd, PSE&G, or Oncor — owns the poles and wires to your address and restores outages, and it is assigned to you by location. The supplier is who generates or buys the power and sets the rate. In a regulated state the utility is also the supplier, so there is one electric company for your address. In a deregulated state, the utility still delivers, but you choose the supplier.

Does my address have electricity choice?

Whether you can choose your electric company by address depends on your state. Thirteen states plus Washington, D.C. — Texas, Ohio, Pennsylvania, Illinois, New Jersey, New York, Massachusetts, Connecticut, Maryland, Maine, New Hampshire, Rhode Island, and Delaware — let residents choose a supplier. If your address sits in one of those, you can compare suppliers against the utility default and lock a better rate. If not, the local utility is your only option and the rate is regulated.

How to switch the supplier at your address

If the electric company by address lookup shows a choice market, switching is simple and the utility, wires, and reliability never change — only the rate and the company on the supply line of your bill. Compare offers against your utility default, pick a plan, and the switch happens on your next meter read with no interruption. Our guide to comparing energy plans walks through it, and the average electric bill by state helps you judge a fair rate.

Why the electric company depends on your exact address

The electric company by address is drawn at the street level, so two homes a few blocks apart can have different delivery utilities, and whether you can shop a supplier flips at state and market boundaries. That is exactly why a by-address lookup beats a generic search: the electric company for your address is a precise answer, not a regional guess. Enter your address once and you get the utility, the choice status, and the suppliers you can actually order.

Major electric delivery utilities by region

Delivery utilities are regional, so the electric company by address is likely one of a handful of large operators in your area. In Texas the delivery utilities include Oncor, CenterPoint Energy, AEP Texas, and TNMP. Ohio has AEP Ohio, Duke Energy Ohio, and FirstEnergy’s Ohio Edison. Illinois runs on ComEd and Ameren, the Northeast on Con Edison, National Grid, PSE&G, and PECO, and the Mid-Atlantic on BGE and Pepco. These are the companies that own the wires to your address and answer when the power goes out, regardless of which supplier you choose.

Knowing your delivery utility matters even in a deregulated market, because it is who you call for an outage and who reads your meter. The supplier only affects the rate. Once the electric company by address lookup shows you both, you know exactly who to call for service and who to shop for savings.

Who delivers power in every state

In 32 states the largest electric utility is also your only electric company. In 13 states plus Washington, D.C., you keep the utility but choose who supplies your power, and in 5 more, choice is limited. The table lists the utility that serves the most homes in each state, its outage line, and, where you can shop, what the default rate is called and when it resets.

Largest utility = most residential customers, from the U.S. Energy Information Administration’s EIA-861 report or the utility’s own published count. Outage lines come from each utility’s website or official notices; where we could not confirm a number, we link to the utility instead. Choice status follows each state utility commission and EIA. Many states have several utilities, so run your full address through the lookup above to confirm yours. Last updated October 1, 2026.

Texas: which utility delivers power to your ZIP code?

Texas is the state where the electric company by address question comes up most, because roughly 85 percent of Texans live in a deregulated area where they pick the retailer but not the wires company. The wires company, called a Transmission and Distribution Utility (TDU), is fixed by your ZIP code and appears on every bill as a delivery charge. There are five: Oncor, CenterPoint Energy, AEP Texas Central, AEP Texas North, and Texas-New Mexico Power (TNMP). Lubbock joined the competitive market in 2024, with Lubbock Power & Light acting as the wires company.

The table below answers the electric company by address question for Texas’s largest deregulated cities by naming the utility that owns the lines. Territories follow old utility boundaries rather than city limits, so a large suburb can straddle two TDUs. When in doubt, the state’s official Power to Choose tool confirms the TDU for any ZIP code, and our energy hub shows the plans available once you know it.

Two cautions before you treat this table as your electric company by address answer. First, Lewisville, League City, Galveston Island, and parts of Denton and Brazos counties are split between TNMP and a neighbor, so a ZIP lookup is the only reliable answer there. Second, the outage number belongs to the wires company, not your retailer. If your lights go out, calling the TDU gets a crew moving; calling the supplier only gets you transferred.

Texas cities where you cannot choose your electric company

About 15 percent of Texans get a different electric company by address answer, because they live inside a municipal utility or electric cooperative that opted out of deregulation. If your address is in one of these cities, the utility below is both your wires company and your only supplier, and no comparison site can change that. Shopping for internet and home security at that address still works normally.

The good news when the electric company by address lookup returns a municipal or co-op name is that the municipal and co-op rates in Texas are often competitive with the best retail plans, and there is no contract to manage. The bad news is that when those rates rise, as several did after Winter Storm Uri to pay down storm debt, there is no way to shop around. If you are moving, the electric company by address question is worth asking before you sign a lease, because the answer decides whether you will ever be able to switch.

Electric company by address: the questions people actually type

Thousands of people search Bing and Google with their own street address and the words “what power company services” in front of it. The lookup above answers that in one step; these are the follow-up questions that come with it.

Why does the lookup ask for a ZIP code instead of my full street address?

Because the electric company that delivers power is assigned by service territory, and territories follow ZIP codes and county lines far more often than individual streets. A ZIP is enough to identify the utility for the overwhelming majority of homes. The rare exceptions are ZIPs split between two utilities (common on the edges of Texas TDU territories and in parts of Ohio and Pennsylvania); when that happens the tool shows both, and your latest bill or the meter tag settles it.

What power company services my address if I just moved in and have no bill yet?

Enter the ZIP in the lookup above. If you want to confirm it, the meter on the outside of the home carries the utility’s name or logo, and the previous occupant’s final bill (often still in the mailbox) names it too. In a deregulated state you then pick the supplier yourself; in a regulated state the utility the tool shows is also the company you call to start service.

Is there one electric company per address, or can there be two?

In regulated states (Florida, Georgia, the Carolinas, most of the West and Southeast), one company delivers the power and sells it, so there is a single answer. In deregulated states (Texas, Ohio, Pennsylvania, Illinois, New York, New Jersey, Maryland, Massachusetts, Connecticut, Maine, New Hampshire, Rhode Island, Delaware, DC), every address has two: the utility that owns the wires and the supplier that sets your rate. The utility is fixed; the supplier is your choice.

How do I get insights on the electric company for my address, such as rates and reliability?

Once the tool identifies your utility, its name links to the state and city pages on this site that show the current average rate, the cheapest plans available, how often the utility raises delivery charges, and (for Texas) the TDU delivery fee that applies regardless of which supplier you choose. For outage history and complaint counts, each utility’s state public utility commission publishes an annual reliability report; the state pages link to them.

How do I find the electric company for an apartment or rental?

The same way as a house: enter the building’s ZIP. The difference is who holds the account. If electricity is in your name, you choose the supplier (in a deregulated state) and the utility is the one the lookup shows. If the landlord includes electricity in rent or the building is submetered, the landlord holds the account and you cannot switch suppliers, but the delivering utility is still the one the tool shows.

What if my address is served by a co-op or a city-owned (municipal) utility?

Then the lookup shows the co-op or municipal utility, and in nearly every case it is also your only option for buying power. Electric cooperatives and municipal utilities are exempt from retail choice even inside deregulated states; Austin Energy, CPS Energy in San Antonio and the Texas co-ops are the well-known examples. You cannot shop suppliers at those addresses, but you can still compare internet, home security and home warranty plans at your address.

Frequently asked questions

How do I find out what electric company services my address?

Use the electric company by address lookup tool above, check your latest electric bill, or view your state utility commission’s service-territory map. The tool is fastest.

Who provides electricity to my address?

The electric company by address is a delivery utility set by your location, plus a supplier. In regulated states they are the same company; in deregulated states you choose the supplier.

Can I choose my electric company by address?

Only if your address is in a deregulated state. There you keep the delivery utility but pick your supplier and rate.

What is the difference between my utility and my supplier?

The utility is the electric company by address: it delivers power and handles outages; the supplier sets the rate. Deregulation lets you shop the supplier, not the utility.

Why does my neighbor have a different electric company?

Service territories are drawn at the street level, so the electric company by address can differ and nearby addresses can fall under different delivery utilities or different choice rules.

How do I know if my address is deregulated?

Enter it in the tool, or check whether your state is one of the 13 plus D.C. with residential electricity choice.

Does switching suppliers change my service?

No. The wires, reliability, and outage response stay with your utility; only the rate and supply company change.

Is the address lookup free?

Yes. Finding the electric company for your address and comparing suppliers is free and never marked up.

Who is my electric provider by ZIP code?

A ZIP code narrows it down but does not settle it, because utility territories are drawn street by street and one ZIP can straddle two utilities. Use your full street address in the lookup tool. In Texas, the ZIP-to-utility table on this page shows which delivery utility covers most of each area, and the tool confirms your exact address.

How do I find the electric company for a home I am moving into?

Ask the seller, landlord or leasing office which utility delivers power, or run the new address through the lookup tool above before move-in day. In a deregulated state, set up the delivery utility and choose a supplier three to five business days before you arrive so the power is on when you get there. Our new home utilities checklist covers the rest of the setup.
