The process of connecting a supply
Connection requests
- New supply, in case you need an electrical connection for a new property, or it is an existing property (which already has a connection) but your supply was not initially planned (for example partition of a local).
- Power Extension / Voltage Change, in case you already have a connection and need to expand the power or change the voltage of your supply. You must also select this option if your supply has a contract but is terminated.
- Temporary: select this option if you need an electrical connection for a short-term supply (fairs, itinerant supplies, etc.).
- Provisional supplied by builders: if you need a provisional electrical connection to perform a work.
- Supplementary supply: if you already have an electrical connection and need a second one for security of supply (relief supply).
- Rehabilitation of buildings that may be associated with a unification/segregation of CUPs,
- Electrification studies for requests for general urban development plans (PGOU) or future urban developments, in initial stages where the distribution of plots and their power is not yet fully defined. This allows an initial capacity study to be carried out for infrastructure forecasting and the reservation of land, without including economic valuations that can be defined at a later stage when the development parameters for each plot are specified.
- Extensions or new distributor points connected ‘downstream’ to the e-distribution network.
To deliver electrical energy to a new supply, it is necessary to enable a connection point to the distribution network and carry out the installation up to the customer's electrical supply. This necessary connection work between the client and network is technically known as a “connection”.
When you need to have a new electrical energy supply or expand the power of an existing one, you must process a request that will entail the execution of a new electrical connection or the adaptation of the network facilities to be able to serve it.
Types
When a new supply requires a connection to the distribution network, you can make your connection requests, using the online forms available in the private area of the website, in the section Connection to the Network / New supply registration/ modification request, for the following cases:
There are three very singular requests for which web management is not yet possible, so they must be opened by sending an e-mail to conexiones.edistribucion@enel.com, attaching the following downloadable form:
