How to connect a new supply to the grid
Connection requests
On this page, you will find out what an electrical connection is, when you need one, what types of requests you can process, and the phases of the procedure until you can set up your supply contract
What is an electrical connection?
The connection is the installation that connects the distribution network to a customer's supply point. In other words, the work required to connect a supply to the distribution network, encompassing both the physical execution and the connection right up to the delivery point.
You need a connection when you want to register a new supply.
When do you need to submit a request?
You must submit a request in any of the following cases:
- You want to set up a new supply contract for a new property or an existing property where your supply was not initially planned (e.g., dividing a commercial premises).
- You already have a connection, but need to increase the power or change the voltage of your supply.
- Your supply had a contract in the past, but has been disconnected for more than three years.
- You need a connection for a short-term supply: fairs, mobile supplies, or other temporary events.
- You need a temporary connection to carry out construction work.
- You already have a connection and need a second one for supply security (backup supply).
- You are a distributor and need to process extensions or new points connected to the e-distribución network, or manage generation and demand feasibilities.
How can you submit the request?
Via the website (most of cases)
You can process your request from the private area of our website, under Grid Connection > New supply registration / modification request.
There you will find the forms for all types of requests: new supplies, power increases, voltage changes, temporary supplies, temporary construction supplies, backup supplies, and extensions or new points for distributor requests.
Via email (building renovations)
If your request relates to a building renovation and involves the unification or segregation of SPUC (supply point codes), it is not yet possible to manage it via the website. In this case, send us an email at conexiones.edistribucion@enel.com and attach the downloadable form available on our website.
Phases of the connection process
From the moment you submit the request until you can contract the supply, the process goes through five phases:
Phase | What it involves |
1. Request submission | You submit your request with the necessary documentation. According to CNMC Circular 1/2024, requests falling under the scope of RD 1183/2020 must be accompanied by a descriptive technical report for the new consumption installation. |
2. Presentation of conditions | We inform you of the technical and financial conditions required to make the connection. |
3. Accepting the conditions | You confirm that you accept the conditions we have presented. |
4. Execution of the works | We carry out the necessary works and installations to connect the supply to the grid. The indicative execution schedule is available on our website (CNMC Circular 1/2024). |
5. Availability to contract | Once the works are completed, the supply point is ready for you to set up a contract with your energy supplier. |
