Grid Connection Conference: New Challenges for Electric Mobility
On 1 June, E‑REDES organised an event in Lisbon that brought together industry experts and organisations to discuss the evolution of grid connections within a changing electricity system. 

The event was divided into two distinct parts. In the morning, the discussion focused on measures to simplify and digitise connection processes. In the afternoon, the focus shifted to technical solutions, with particular emphasis on electric mobility and the new sub-metering model, which forms part of the evolution of the sector’s legal framework.

The sub-section breaks down the consumption figures for electric mobility

Sub-metering allows for the independent measurement of electricity used at charging points, even when they are connected to the main supply. This model is introduced under Decreto‑Lei n.º 93/2025.

The presentation highlighted the changes to the electric mobility model, in which sub-metering is presented as one of the possible options, though its implementation is not mandatory.

In practice, sub-metering creates an internal metering point with a new delivery point code (DPC). The process comprises three stages: application, certification and contract, and requires the validation of documents and certification of the installation.

Under this model, consumption associated with electric mobility is handled independently, without the need for a dedicated connection to the grid. This solution allows for more flexible management of charging and keeps pace with developments in the regulatory framework.
