In permanent installations, there are two segments to be made within low voltage connections:

Power exceeding 41.4 kVA

We have defined the value of 41.4 kVA as the requested power above which a prior assessment of the conditions for connection to the low voltage network will be required.

The evaluation of the total power requested corresponds to the sum of the powers of all the installations fed from the same branch, according to the concurrency coefficients provided for in the Technical Rules for Low Voltage Electrical Installation (RTIEBT), according to the electrical specifications.

If the building is new and has more than one branch, information must be provided on all planned supplies, so that we can assess the need to define special technical conditions for connections to the grid.

Check here the addresses where to send the documentation associated with your request of power grid connection exceeding 41.4 kVA.

Powers less than or equal to 41.4 kVA

We consider that requests for requested power less than 41.4 kVA do not generally require prior assessment of connection conditions.

For these requests, the technical evaluation and definition of the respective charges will be made in the request of connection to the electric network.

What is a Building Identification Number and how can I get one?
The Building Identification Number (NIP) is a sequential numerical identifier assigned to each building for the purposes of processing and providing information on buildings. In addition to the georeferenced graphic representation of the building, any other data and/or elements that allow for a better characterisation of the building are associated with this number. This number can be consulted directly on the SRIESP website in the "NIP Consultation" option, available in the main SRIESP menu, after the technician in charge has registered.
