Details of your supply

Check your supply details using this service

Imagen contador

This service allows you to view technical and contractual information about your electricity supply, from the supply address to its technical specifications, associated contracts, and available services.

 

What information will you find?

 

Supply address

Location details for the supply point: province, municipality, town, ZIP code, and full address.

 

Technical details

Electrical characteristics of the supply. These are the most common fields:

  • Supply voltage
  • Voltage type
  • Power (kW)
  • Reserved extension power
  • Documentation date
  • Official activation date of the supply
  • Essential supply
  • Indicates whether the supply point has special protection against outages

 

CAU and access requests

If you have registered self-consumption, here you will find the CAU code (Self-Consumption Code), a unique 26-digit code that identifies your energy generation installation, much like an ID number. It is issued by the distributors and allows you to connect your supply point to your solar installation, which facilitates consumption monitoring and the offsetting of surplus energy.

You can also view the most recent change request processed for the supply: registrations, cancellations, modifications, or changes in the electricity supplier.

 

ATR Contracts

An ATR (Third-Party Network Access) contract is the agreement that allows your electricity supply to use the distribution network to receive power.

It is signed by your electricity supplier with the distribution company (not directly by the customer) and governs how you access the network: power, rate, technical conditions, etc.

In other words, the ATR contract is the “technical contract” that defines how electricity reaches your supply point, while your contract with the supplier defines the financial terms (price, billing, etc.).

This service allows you to view all the technical conditions of your electricity supply in one place, specifically:

  • Who your supplier is
  • What rate you have
  • What power capacity you have contracted for each period
  • Since when the contract has been active

 

Supplier History

In this section, you will find the complete record of access requests linked to your supply point. The system displays the most recent change request processed—whether it’s a new connection, disconnection, modification, or change of supplier—and the dates associated with the communication processes between the distributor and your current supplier. If you need more details about a specific request, you should contact your electricity supplier directly.

 

Downloading Meter Reading and Usage Certificates

Access the official certificates for the period during which you were the account holder. The process is simple:

  1. Select the individual or business name for which you want to download the certificate and click “Apply.”
  2. Select the CUPS (supply point) for which you need the certificate.
  3. Specify the download period—start and end month and year—and request the download.
  4. Once generated, select the certificate from the list and click “Download” to obtain the PDF.

 

Request for refund of the security deposit

If you previously paid a security deposit for your service connection, you can request a full refund online. To do so, you must provide the supply’s CUPS, the bank account in the account holder’s name where the payment should be made, and attach the necessary documentation: the bank certificate (required), the account holder’s ID (optional), and, if the applicant is not the contract holder, a power of attorney. 

 

What else can you do using this service?

In the right-hand side menu, you’ll find shortcuts to the most relevant services for the supply point you’re viewing:

Enable or disable notifications for scheduled outages and service disruptions

  • View and download load profiles (your consumption in 15-minute intervals)
  • View the maximum power you’ve drawn in recent months
  • Reset the ICP (power control switch) and check the meter in real time
  • Download meter reading and consumption certificates
  • View associated self-consumption information
  • What information can I view about my supply point?

    • In the supply details, you’ll find the full address of the supply point, the technical specifications of the installation (voltage, grid type, and maximum power), and the active grid access contracts (ATR) you have. If you have registered self-consumption, you’ll also see the CAU code and its type.

  • What does it mean if my supply is listed as “essential”?

    • It means your supply point has special protection against outages. This applies to facilities that, due to their operations, require continuous and priority electrical service. If you believe your supply should have this status and it is not marked, contact your electricity supplier.

  • Why are there no results in the access request history?

    • The portal only displays the most recent change request processed for the supply. If no results appear, it may mean that no request for registration, cancellation, modification, or change of supplier has been processed yet, or that the information is not yet available in the system. In that case, contact your supplier for more information on the status of your requests.

  • Can I download consumption certificates for any period?

    • You can only download reading and consumption certificates for the periods during which you were the account holder for that supply point. If the account holder was another person or company during any period, that data will not be available to you. Additionally, the certificates are linked to a specific CUPS, so you must select the correct supply point before specifying the download period.

      The certificates are generated in PDF format and can be used as official proof for third parties, such as government agencies or financial institutions.

  • What documentation do I need to request a refund of the security deposit?

    • To process the refund, you will need: a bank statement certifying that the account indicated is in the name of the contract holder or the deposit holder (required), and optionally the deposit holder’s ID (front side only). If the person making the request is not the holder themselves, you must also attach a power of attorney. You can include additional documentation in the “Other documents” section if you deem it necessary.
