What You'll Learn

Ask the previous owners or your real estate agent
If you're in the process of buying a new home, it's a good idea to find out about your electricity provider before you move in. One way to do this is to ask the previous owners or your real estate agent. During the closing process, you can reach out to your real estate agent or the seller's agent to find out the utility companies for the address you're moving to. Don't forget to ask if there is a separate supplier, as in some areas, the utility company and the electricity provider are different.
If you're unable to get in touch with the previous owners or their agent, you can try contacting your local city or town hall. They may be able to tell you the local utility company for your address. Additionally, they can inform you if your area has energy choice, meaning you can choose your energy supplier.
In some places, such as Texas, the electricity market is deregulated, and you must choose your electricity supplier. In such cases, you can use an ESID Lookup Tool (Electricity Service Identifier) to find your utility company by entering your address. This tool will also show you offers from retail electricity providers, allowing you to compare plans and rates to find the best option for your needs.
Alternatively, if you have access to an energy bill or online account from the previous owners, you can find the contact details of the energy supplier and reach out to them directly. You can also look for the Distributor ID number on the bill, which can help identify the network operator for your connection. Remember, the network operator is different from your energy supplier, but they can provide you with your supplier's details if needed.

Use an ESID Lookup Tool
If you want to find out which electric company services a particular house, you can use an ESID Lookup Tool. ESID stands for Electric Service Identifier, and it is a unique number assigned to a property address. It is sometimes referred to as an ESIID, ESI ID or ESI-ID.
The ESID Lookup Tool allows you to enter an address to find the corresponding ESID number. This number is not visible on your meter but is tied to a physical address. Each ESID is unique to a specific meter location, and each delivery company has a different number sequence. For example, ESIDs for Oncor typically start with 1044, while those for CenterPoint usually begin with 10089.
By using the ESID Lookup Tool, you can determine the electric utility company for a particular address, as well as other important information. The tool will provide you with your unique ESID number, the meter status, and the electric utility company servicing that address. Additionally, you may also see offers from retail electricity providers.
It is important to note that if you are unable to find your ESID number or if the tool returns an error, it could be because the meter is new and hasn't been set up yet. In such cases, you may need to contact the utility company or the website support for assistance in setting up the meter and getting your power turned on.
The ESID Lookup Tool is particularly useful in deregulated areas, where you have the option to choose your electricity provider. In regulated areas, one utility company typically provides all services, while in deregulated areas, you can select your retail electricity provider, who will sell you the electricity and manage customer service, billing, and plan options.

Find your local utility company
Finding your local utility company can be a bit tricky, especially in deregulated areas where you must choose your electricity supplier. Here are some ways to find your local utility company:
Ask the Previous Owners or Your Real Estate Agent
If you're buying a new home, don't wait until you move in to find out who your electric company is. During the closing process, reach out to your real estate agent or the seller's agent to find the utility companies for your new address. Ask if there is a separate supplier for electricity and natural gas.
Visit Your Local City Hall
You may be able to find your local utility company by contacting your town hall or municipal building. They can also inform you if your area has energy choice, meaning you can select your energy supplier.
Check Your Utility Bill
If your utility company bills you directly, look for a line item or section on your bill that indicates the type of energy supply, such as "natural gas supply" or "gas supply charges." This can help you identify if you have a separate supplier for natural gas.
Use Online Tools and Hotlines
If you live in Texas, you can use the ElectricityPlans ESID Lookup Tool by entering your address to find your utility company. Additionally, some websites offer energy comparison tools where you can enter your zip code to see all available electricity providers in your area. Similarly, if you live in Massachusetts, you can use the search bar on the Mass.gov website to find the companies providing electric services to your city or town.
In England, Scotland, or Wales, you can call 105, the free power cut emergency number, to connect with your local electricity distribution network operator. For Northern Ireland, the number is 03457 643643.
Understand the Difference Between Network Operators and Energy Suppliers
Your electricity network operator maintains the wires that bring electricity to your home, while your energy supplier is the company that bills you for your energy usage. Your network operator may be able to provide you with your supplier's details if you don't have a recent bill.

Check your energy bill
If you receive a paper bill through the mail, the energy supplier's name and logo will be printed on the bill. The bill will also include the company's contact information, such as their address, phone number, and email.
If you have an online account with your energy supplier, you can log in to view your bill and find the company's contact details. Most energy suppliers will have an online portal where you can access your bills and account information.
Energy bills will also include pricing information, such as the price per kilowatt-hour (kWh) for electricity and per cubic feet (Ccf) or therm for natural gas. This information can be useful for comparing prices with other energy suppliers and determining if you are on the best plan for your needs.
Additionally, your energy bill may include a ''Distributor ID' number, which can help you identify your electricity network operator. This number is different from your energy supplier, as the network operator is responsible for the maintenance of wires and pipes that carry electricity and gas.
Finally, your energy bill will likely include a unique identifier for your electricity supply, such as a Meter Point Administration Number (MPAN). This number helps energy companies track your electricity usage and ensure accurate billing.

Contact your town hall
If you are wondering which electric company services a particular house, one way to find out is by contacting your town hall. Visiting the town hall or municipal building may allow you to find more information about the utility companies that service your area or if you have the option to choose your provider.
Many towns and cities across the United States have deregulated their energy markets, allowing customers to choose their energy supplier. In such cases, the utility and the energy provider are different entities. The utility handles the transmission of electricity but does not provide the electricity itself. Your town hall can inform you if your area has energy choice.
If you are unsure whether your area offers energy choices, you can contact your local utility or state regulatory commissions. They can guide you on the utility companies that service your address and help you understand your utility and energy supplier options. You can then use your energy bill to understand the pricing of your energy plan.
Additionally, your town hall may be able to provide information on natural gas providers in your area. If your utility bills you, look for a line item or section that mentions "natural gas supply" or "gas supply charges." Your supplier may also bill you directly.
