I’m a self-supplier

How can I manage my self-supply request?

What type of self-consumption do you want to connect?

If you want to request a self-supply connection

*With no surplus

*Or with surplus, with a capacity equal to or lower than 15 kW, located on developed land and connected to the equipment and services required by urban planning legislation.

You must process the formality with the relevant authority and your supply company. Before that, don’t forget to request your Self-Supply Code (CAU) on this page.

When you have your CAU, you will have to legalise your installation with your Autonomous Community, and you will also be able to apply for the contract with your supply company.

If you want to request a self-supply connection.

*With surplus, with a capacity over 15 kW.

*With surplus, with a capacity equal to or lower than 15 kW, NOT located on developed land and connected to the equipment and services required by urban planning legislation.

Your self-supply will be associated with a network access and connection process with your distribution company. If that is us, you can easily manage this process by registering in our Private Area.

And, when we provide your Self-Supply Code (CAU), you will have to legalise your installation with your Autonomous Community and you will be able to apply for the contract with your supply company.

What is a CAU?

A Self-Supply Code (CAU) is a unique self-supply identifier. It will comprise the 22-character Universal Supply Point Code (CUPS) of your supply followed by A and three zeros. The distribution company is responsible for providing you with the code and you will need it on all self-supply requests to register your installation in your Autonomous Community. In our case, you can get it using this simple form.

What is a CIL?

A CIL is a liquidation code used to quantify and liquidate (where appropriate) surplus energy generated by an installation. It will comprise the generation Universal Supply Point Code (CUPS) followed by 001. The distribution company will be responsible for providing you with the code when you complete your connection request. Production surpluses must be liquidated when there is no offsetting. But we will always give you the code in case you need it in the future.

Check if your installation will need access and connection, and get your Self-Supply Code (CAU)
